text: The use of continuous fiber-reinforced thermoplastics (FRTP) in automotive
industry increases due to their excellent material properties and possibility
of rapid processing. The scale spanning heterogeneity of their material structure
and its influence on the material behavior, however, presents significant challenges
for most joining technologies, such as self-piercing riveting (SPR). During mechanical
joining, the material structure is significantly altered within and around the
joining zone, heavily influencing the material behavior. A comprehensive understanding
of the underlying phenomena of material alteration during the SPR process is essential
as basis for validating numerical simulations. This study examines the material
structure at ten stages of a step-setting test of SPR with two FRTP sheets with
glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage
phenomena within different areas of the setting test are analyzed three-dimensionally
and key parameters are quantified. Dominating phenomena during the penetration
of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF)
and fiber bending, while delamination, fiber kinking and roving splitting are
also observed. At the final stages, the bottom layers of the second sheet collapse
and form a bulge into the cavity of the die.

text: 'Fiber reinforced plastics (FRP) exhibit strongly non-linear deformation behavior.
To capture this in simulations, intricate models with a variety of parameters
are typically used. The identification of values for such parameters is highly
challenging and requires in depth understanding of the model itself. Machine learning
(ML) is a promising approach for alleviating this challenge by directly predicting
parameters based on experimental results. So far, this works mostly for purely
artificial data. In this work, two approaches to generalize to experimental data
are investigated: a sequential approach, leveraging understanding of the constitutive
model and a direct, purely data driven approach. This is exemplary carried out
for a highly non-linear strain rate dependent constitutive model for the shear
behavior of FRP.The sequential model is found to work better on both artificial
and experimental data. It is capable of extracting well suited parameters from
the artificial data under realistic conditions. For the experimental data, the
model performance depends on the composition of the experimental curves, varying
between excellently suiting and reasonable predictions. Taking the expert knowledge
into account for ML-model training led to far better results than the purely data
driven approach. Robustifying the model predictions on experimental data promises
further improvement. '

text: The importance of fiber-reinforced plastics for lightweight construction applications
is steadily increasing due to their outstanding weight-specific property values.
However, a decisive disadvantage of these composite materials has so far been
the high material and process costs, which is why fiber-reinforced plastics are
almost exclusively used in small to medium-sized series. Optimization of manufacturing
methods is of great importance to reduce the production cost. In this study, two
concepts are proposed that can optimize vacuum assisted light resin transfer molding
(VA-LRTM) further, leading to a possibility of fully automatic process. Conventional
VA-LRTM methods are used to produce complex fiber-reinforced plastics (FRP) and
hybrid components. Traditional molds used to produce components via VA-LRTM are
sealed using polymer materials to prevent the leakage of matrix system. The seals
undergo tremendous amounts of thermal, chemical, and mechanical loadings. Thus,
sealings must be replaced in short intervals. In the current study, a concept
where sealing is achieved by accelerating the curing of matrix system itself with
the help of heating elements and catalysts resulting in a self-sealing approach
is proposed. Another concern is mold surface contamination during component production.
To address this, a modified automatic cleaning technique based on ultrasonic cleaning
was proposed which can be integrated into the production line with minimum modification.
Both the proposed concepts were validated and optimized using experiments, simulations,
and analytical approaches by producing metal-FRP hybrid shafts.

text: 'Polymer composites represent the industry standard in injection molding for
the production of plastic components with increased requirements in terms of heat
resistance and stiffness. In the field of laser sintering (LS), these materials
are less common so far. In order to extend the available material variety for
the LS process, new ceramic-filled Polyamide 613 powders are investigated within
the scope of this work. Here, the resulting properties from two different powder
production methods are compared. One filled powder is produced by dry blending
and the other powder with the same filler and filling ratio is produced by encapsulating
the filler particles inside the polymer particles within the dissolution-precipitation
process. It was found that encapsulating the filler particles can provide certain
benefits for the processability, for example an improved powder flowability or
better filler dispersion. However, encapsulating the filler also alters the thermal
properties of the precipitated powder. '

text: AbstractPure iron is very attractive as a
biodegradable implant material due to its high biocompatibility. In combination
with additive manufacturing, which facilitates great flexibility of the implant
design, it is possible to selectively adjust the microstructure of the material
in the process, thereby control the corrosion and fatigue behavior. In the present
study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured
by electron beam melting (EBM). The microstructure, the corrosion behavior and
the fatigue properties were studied comprehensively. The investigated sample conditions
showed significant differences in the microstructures that led to changes in corrosion
and fatigue properties. The EBM iron showed significantly lower fatigue strength
compared to the HR iron. These different fatigue responses were observed under
purely mechanical loading as well as with superimposed corrosion influence and
are summarized in a model that describes the underlying failure mechanisms.

text: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'

the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon
detectors on a silicon substrate using laser lithography. We show saturated internal
detection efficiencies with wire widths ranging from 0.59 µm
to 1.43 µm under illumination at 1550 nm. We demonstrate
both straight wires, as well as meandered structures. Single-photon sensitivity
is shown in devices up to 4 mm in length. Laser-lithographically written devices
allow for fast and easy structuring of large areas while maintaining a saturated
internal efficiency for wire widths around 1 µm."

text: Wood–plastic composites (WPC) are enjoying a steady increase in popularity.
In addition to the extrusion of decking boards, the material is also used increasingly
in injection molding. Depending on the formulation, geometry and process parameters,
WPC tends to exhibit irregular filling behavior, similar to the processing of
thermosets. In this work, the influence of matrix material and wood fiber content
on the flow, mold filling and segregation behavior of WPC is analyzed. For this
purpose, investigations were carried out on a flow spiral and a sheet cavity.
WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow
path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC.
The opposite behavior occurs at higher wood contents due to the different shear
thinning behavior. Slightly decreased wood contents could be observed at the beginning
of the flow path and greatly increased wood contents at the end of the flow path,
compared to the starting material. When using the plate cavity, flow anomalies
in the form of free jets occur as a function of the wood content, with TPU exhibiting
the more critical behavior. The flow front is frayed, but in contrast to the flow
spiral, no significant wood accumulation could be detected due to the shorter
flow path lengths.

text: Carbon fiber reinforced plastics (CFRPs) gained high interest in industrial
applications because of their excellent strength and low specific weight. The
stacking sequence of the unidirectional plies forming a CFRP laminate, and their
thicknesses, primarily determine the mechanical performance. However, during manufacturing,
defects, e.g., pores and residual stresses, are induced, both affecting the mechanical
properties. The objective of the present work is to accurately measure residual
stresses in CFRPs as well as to investigate the effects of stacking sequence,
overall laminate thickness, and the presence of pores on the residual stress state.
Residual stresses were measured through the incremental hole-drilling method (HDM).
Adequate procedures have been applied to evaluate the residual stresses for orthotropic
materials, including calculating the calibration coefficients through finite element
analysis (FEA) based on stacking sequence, laminate thickness and mechanical properties.
Using optical microscopy (OM) and computed tomography (CT), profound insights
into the cross-sectional and three-dimensional microstructure, e.g., location
and shape of process-induced pores, were obtained. This microstructural information
allowed for a comprehensive understanding of the experimentally determined strain
and stress results, particularly at the transition zone between the individual
plies. The effect of pores on residual stresses was investigated by considering
pores to calculate the calibration coefficients at a depth of 0.06 mm to 0.12
mm in the model and utilizing these results for residual stress evaluation. A
maximum difference of 46% in stress between defect-free and porous material sample
conditions was observed at a hole depth of 0.65 mm. The significance of employing
correctly calculated coefficients for the residual stress evaluation is highlighted
by mechanical validation tests.
