text: "The state of the art shows that PBF-LB/M offers great potential for pressure-loaded
parts, with significant weight reductions and simultaneous optimization of flow
resistance. This study is aimed at applying existing calculation methods for pressure-loaded
parts to additively manufactured pipe structures, considering the two materials
EN AC-43000 (3.2381, AlSi10Mg) and AISI 316L (1.4404, X2CrNiMo17-12-2). For this
purpose, systematic tensile tests are carried out for both materials. In addition,
a statistical evaluation is performed to determine the design-relevant strength
characteristics with a survival probability Ps of 97.5 % for both materials in
the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half
of which are heat treated, geometrically measured and then subjected to a burst
pressure test to experimentally determine the failure-critical internal pressure.
These results are compared with calculated burst pressures. The calculations are
based on the application-relevant methods identified in this study, considering
the strength values determined for the respective material condition. This comparison
is used to assess the suitability of the calculation methods for additively manufactured
pipe structures, based on the materials investigated."

text: Um die international und national beschlossenen Klimaziele zu erreichen, müssen
die verkehrsbedingten Emissionen in der Bundesrepublik Deutschland drastisch reduziert
werden. Hierzu bedarf es einer umfassenden Mobilitätswende, welche die Etablierung
emissionsärmerer und effizienterer Mobilitätsformen umfasst. Ein Lösungsansatz
können on-demand Dienste bieten, die den öffentlichen Personennahverkehr bedarfsgerecht
gestalten und so dessen Akzeptanz steigern. Zahlreiche bisher eingeführte on-demand
Dienste mussten jedoch nach Beendigung des Projekt- bzw. Förderzeitraums wieder
eingestellt werden. Maßgebliche Herausforderungen waren die Integration der Dienste
in die bestehenden ÖPNV- und Mobilitäts-Strukturen sowie teilweise damit einhergehende
ökonomische Aspekte. In diesem Beitrag wird eine Methode vorgestellt, welche neben
der Einführung neuartiger Mobilitätsdienste auch die Entwicklung eines nachhaltigen
Mobilitäts-Ökosystems anstrebt. Der Fokus liegt dabei auf ländlich geprägten Regionen
und ihren besonderen Herausforderungen im Bereich des öffentlichen Nahverkehrs.
Die Methode beschreibt ein fünf-phasiges Handlungsschema, in welchem Potenziale
bestehender Strukturen genutzt, Mobilitäts-Stakeholder eingebunden und verhärtete
Mobilitätsverhalten allmählich positiv verändert werden. Anhand der Initiative
Neue Mobilität Paderborn wird aufgezeigt, dass mithilfe der Methode erste Schritte
hin zu einem Mobilitäts-Ökosystem absolviert werden können. Darüber hinaus werden
Einführungsszenarien für die neuartige, sich noch in der Entwicklung befindliche
Mobilitätslösung NeMo.bil in einer Beispielregion erarbeitet.

text: Fibre-reinforced polymers are increasingly used due to their high specific
strength, making them suitable for local sheet metal reinforcement. This allows
improved overall mechanical properties with reduced wall thickness of the sheet
metal part and, thus, lower weight of the components. One of the main focuses
of research into such hybrid structures is on the adhesive properties and the
respective failure behaviour of the interfaces. Generally, the failure behaviour
under the influence of mechanical loads can be divided into adhesive, cohesive
and mixed-mode failure. The correlation between observed failure behaviour and
adhesion properties of the hybrid composite materials is analysed in detail in
this work. The hybrid composite consists of an aluminium sheet of the alloy EN
AW‑6082 T6 and thermoset carbon fibre-reinforced plastic (CFRP) prepreg. The aluminium
sheet was laser pretreated before hybrid production to improve the adhesion properties.
The specimens studied were produced by the prepreg pressing process, in which
the components are cured and joined simultaneously. The influences of the thickness
of the CFRP part, the layup, the fibre orientation at the boundary layer, and
the laser pretreatment parameters on the properties of the hybrid joints were
investigated.

text: 'Abstract. Accurate Finite Element Modeling (FEM) of joints is essential
in the design of complex mechanical systems such as automotive body-in-white (BIW)
structures, as it plays a critical role in evaluating their performance. Although
well-established techniques exist for modeling rotationally symmetric joints,
there remains a significant gap in effectively modeling non-rotationally symmetric
joints. These joints are particularly relevant in the automotive BIW, where they
can better accommodate anisotropic loading conditions. In this study, strategies
for modeling non-rotationally symmetric joints were explored using finite element
simulations in LS-DYNA. The findings demonstrate that discrete beam elements can
capture the anisotropic characteristics of such joints. Two models were tested:
a single-beam model for stiffness periodicity every 90°, and a three-beam model
for stiffness periodicity every 120°. Force responses, stress distribution, and
sheet bending behaviors were analyzed, confirming that discrete beam elements
can accurately represent direction-dependent stiffness. These results establish
a foundation for developing advanced joint modeling strategies in complex mechanical
systems.'

text: To reduce transport-related environmental impacts, innovative mobility system
approaches such as on-demand services are being developed. These can include operating
vehicles that differ regarding their characteristics and application profile from
privately owned cars in motorized individual transport. Studies on life cycle
assessment and life cycle engineering of vehicle lightweight structures are mainly
limited to these privately owned cars and the impact category of climate change.
In this paper, a method for life cycle assessment-based engineering of lightweight
structures in vehicles for various mobility system applications, including on-demand
mobility services, is developed. The method enables the holistic life cycle assessment
of lightweight structures in different mobility system applications considering
parameter changes at the upstream products, component, subsystem, vehicle and
mobility system levels, as well as the integration of results into engineering
activities. A case study is used to show that the vehicle and mobility system
application of lightweight structures can significantly influence their environmental
impacts and the selection of ecologically preferable product designs. The application
in vehicles for on-demand mobility services can lead to an increase in absolute
use stage energy demand and environmental impacts compared to applications in
privately owned vehicles for motorized individual transport. However, normalized
to the transport performance provided, the lifecycle environmental impacts of
structural components in vehicles for on-demand mobility services can be lower
than in vehicles for motorized individual transport. The paper contributes methodically
and with quantitative results to improved decision making in life cycle engineering
activities for lightweight structures in mobility system applications.

text: This paper discusses the influence of joint orientation with non-rotationally
symmetric geometry, on load distribution and structural behavior. The focus is
on understanding how changes in the alignment of individual joints affect the
distribution of load, neighboring joints, and the overall performance of the component.
Lap shear specimens with multiple joints arranged in a line are analyzed to explore
these effects. Simplified models are used to model the joints in finite element
simulations, allowing for efficient yet accurate analysis of the load distribution
and structural response under varying joint orientations. Variations in joint
orientation result in measurable changes in the distribution of forces on adjacent
joints, influencing their behavior and that of the overall assembly. Experimental
validation confirms the numerical results, providing deeper insights into the
interaction between individual joints and their surroundings. This work contributes
to the development of systematic approaches for optimizing the design of components
with non-rotationally symmetric joints. The study highlights the importance of
considering directional properties of joints in designing structural components.

text: As global industries seek to reduce energy consumption and lower CO2
emissions, the need for sustainable, efficient maintenance processes in manufacturing
has become increasingly important. Traditional mold cleaning methods often require
complete tool disassembly, extended downtime, and heavy use of solvents, resulting
in high energy costs and environmental impact. This study presents a novel localized
ultrasonic cleaning process for injection molding tools that enables targeted,
in situ cleaning of mold cavities without removing the tool from the press. A
precisely positioned ultrasonic transducer delivers cleaning energy directly to
contaminated areas, eliminating the need for complete mold removal. Multiple cleaning
agents, including alkaline and organic acid solutions, were evaluated for their
effectiveness in combination with ultrasonic excitation. Surface roughness measurements
were used to assess cleaning performance over repeated contamination and cleaning
cycles. Although initial tests were performed manually in the lab, results indicate
that the method can be scaled up and automated effectively. This process offers
a promising path toward energy-efficient, low-emission tool maintenance across
a wide range of injection molding applications.

text: Over the past decades, the importance of lightweight structures in the aircraft
and automotive industries has steadily increased due to regulations aimed at reducing
global warming. Work hardened steel alloys are commonly used for lightweight applications,
but they face stability issues when the material thickness reaches certain thresholds.
Fiber Reinforced Plastics (FRP) offer a viable alternative due to their high strength-to-weight
ratio, but they are often expensive due to long production cycles and high material
costs. A feasible solution lies in hybrid lightweight designs that utilize expensive
FRP materials only in highly stressed areas, achieving a balance between low mass
and acceptable cost. These hybrid structures are lighter than metal components
and more cost-effective compared to fully FRP structures, without compromising
mechanical properties. This study focuses on producing rotationally symmetrical
hybrid structures using Resin Transfer Molding (RTM) combined with vacuum assistance
in a single-stage process. The research examines the effects of injection pressure,
mold temperature, and the interface between metal and FRP. The mechanical characterization
of these hybrid structures was conducted to assess their performance under torsion,
compression, and interlaminar shear strength (ILSS) loading conditions. The results
indicate that hybrid designs can offer a lightweight alternative without compromising
mechanical properties.

text: Currently, the need for resource efficiency and CO2 reduction is growing
in industrial production, particularly in the automotive sector. To address this,
the industry is focusing on lightweight components that reduce weight without
compromising mechanical properties, which are essential for passenger safety.
Hybrid designs offer an effective solution by combining weight reduction with
improved mechanical performance and functional integration. This study focuses
on a one-step manufacturing process that integrates forming and bonding of hybrid
systems using compression molding. This approach reduces production time and costs
compared to traditional methods. Conventional Post-Mold Assembly (PMA) processes
require two separate steps to combine fiber-reinforced plastic (FRP) structures
with metal components. In contrast, the novel In-Mold Assembly (IMA) process developed
in this study combines forming and bonding in a single step. In the IMA process,
glass-mat-reinforced thermoplastic (GMT) is simultaneously formed and bonded between
two metal belts during compression molding. The GMT core provides stiffening and
load transmission between the metal belts, which handle tensile and compressive
stresses. This method allows to produce hybrid structures with optimized material
distribution for load-bearing and functional performance. The process was validated
by producing a lightweight hybrid brake pedal. Demonstrating its potential for
efficient and sustainable automotive production, the developed hybrid brake pedal
achieved a 35% weight reduction compared to the steel reference while maintaining
mechanical performance under quasi-static loading

text: Injection molding plays a pivotal role in modern manufacturing, enabling the
mass production of complex components with high precision. However, traditional
tooling methods often face challenges related to thermal management, design constraints,
and material efficiency. This study examines the use of additive manufacturing
(AM) in the development and optimization of injection molding tools to overcome
these limitations. A novel prototype was fabricated using AM techniques, incorporating
integrated cooling channels and optimized lattice structures to enhance thermal
performance and simplify the manufacturing process. Experimental validation demonstrated
the prototype’s effective integration into a vacuum-assisted resin transfer molding
(VA-LRTM) system without requiring modifications to existing tooling setups. The
results showed significant improvements in temperature regulation, reduced cycle
times, and consistent mechanical properties of the molded components compared
to conventional approaches. By reducing the number of tool components and eliminating
the need for support structures during manufacturing, AM also minimized material
waste and post-processing requirements. This research highlights the transformative
potential of additive manufacturing in injection molding tool design, offering
increased flexibility, cost efficiency, and enhanced functionality to meet the
evolving demands of modern industrial applications.

text: The degree of crosslinking in unidirectional prepreg materials was investigated
using differential scanning calorimetry to assess their curing behavior and thermal

text: The corrosion behavior of a hybrid laminate consisting of laser-structured
aluminum EN AW-6082 ∪ carbon fiber-reinforced polymer was investigated. Specimens
were corroded in aqueous NaCl electrolyte (0.1 mol/L) over a period of up to 31
days and characterized continuously by means of scanning electron and light microscopy,
supplemented by energy dispersive X-ray spectroscopy. Comparative linear sweep
voltammetry was employed on the first and seventh day of the corrosion experiment.
The influence of different laser morphologies and production process parameters
on corrosion behavior was compared. The corrosion reaction mainly arises from
the aluminum component and shows distinct differences in long-term corrosion morphology
between pure EN AW-6082 and the hybrid laminate. Compared to short-term investigations,
a strong influence of galvanic corrosion on the interface is assumed. No distinct
influences of different laser structuring and process parameters on the corrosion
behavior were detected. Weight measurements suggest a continuous loss of mass
attributed to the detachment of corrosion products.

text: Within the current energy and environmental crisis, new material- and energy-saving
processes are needed. For this reason, this study focuses on the development of
a new forming technology for Ti-6Al-4V sheet metal. It is based on combination
of solution treatment by resistive heating with rapid tool-based quenching and
subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening
already known for steels and hot die quenching known for aluminium alloys. One
of the main influencing factors for this process is the heat transfer coefficient
(HTC). It is an important driver for adjustment of basic parameters, as selection
of tool material or the forming speed but also plays an important role while elaborating
temperature distribution in the numerical model. Therefore, a new and unique test
rig was developed to determine the HTC and to perform tool-based heat treatment
at specimen level under laboratory conditions. The test rig was used to investigate
the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further
the effect of heat treatment in the test rig and tool-based quenching on microstructure
and mechanical properties was studied. To improve the prediction of the temperature
distribution of the titanium during cooling, the HTC was integrated into the numerical
process simulation

text: Additive manufacturing of metallic components often results in the
formation of columnar grain structures aligned along the build direction. These
elongated grains can introduce anisotropy, negatively impacting the mechanical
properties of the components. This study aimed to achieve controlled solidification
with a fine-grained microstructure to enhance the mechanical performance of printed
parts. Stainless steel 316L was used as the test material. High-intensity ultrasound
was applied during the direct energy deposition (DED) process to inhibit the formation
of columnar grains. The investigation emphasized the importance of amplitude changes
of the ultrasound wave as the system’s geometry continuously evolves with the
addition of multiple layers and assessed how these changes influence the grain
size and distribution. Initial tests revealed significant amplitude fluctuations
during layer deposition, highlighting the impact of layer deposition on process
uniformity. The mechanical results demonstrated that the application of ultrasound
effectively refined the grain structure, leading to a 15% increase in tensile
strength compared to conventionally additively manufactured samples.

text: Abstract. Traditionally, joints are cylindrical and rotationally symmetric.
In the present study, non-rotationally symmetric joints are used for joining steel
and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also
analyzes the impact of non-rotational symmetric joint rotation on the load-bearing
capacity. Single lap joint specimens were fabricated using the In-Mold assembly
technique for joining steel sheets with GMT. Tensile shear tests were performed
on different orientations of the joint geometry, and it was observed that changing
the joint orientation influences the load-bearing capacity. The joints are constitutively
modeled using beam elements and the influence of joint rotation on load distribution
is examined through a static simulation study.
