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: The degree of crosslinking in unidirectional prepreg materials was investigated
using differential scanning calorimetry to assess their curing behavior and thermal
characteristics. To complement these measurements with a non-destructive, in-situ
method, the propagation properties of guided acoustic waves in cured carbon fibre-reinforced
epoxy plates were analysed. Correlations between the degree of crosslinking and
acoustically determined mechanical properties were drawn to enable a future non-destructive
evaluation approach.

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: To improve the mechanical performance and to address current shortcomings
of adhesive bonds such as bond degradation due to aging, a pulsed laser surface
pretreatment of the metal surfaces of aluminum AW 6082-T6 joints with epoxy adhesive
E320 is investigated. The surface treatment of the specimens resulted in increased
single-lap shear (SLS) strengths before and after hydrothermal aging in 80°C hot
water compared to nonpretreated reference specimens. In order to reveal the correlations
of laser parameters, resulting surface morphologies and the SLS strength, differently
laser pretreated surfaces were characterized at the micro- and nanoscale using
optical and scanning electron microscopies. The surface enlargement was quantified
with a digital image analysis of cross-sections prepared from the joint interfaces.
An analysis of variances (ANOVA) of the SLS results indicated that the laser parameters
power and pulse frequency were most critical for obtaining high SLS strengths.
Pretreated joint surfaces with a high micro- and nano-surface enlargement and
deep solidification structures provide high SLS strengths of up to 50 MPa and
almost negligible aging losses of merely 4%. Undercut structures on the pretreated
surfaces were found to be beneficial for the mechanical and aging properties when
only limited micro- and nanostructuring was applied.

text: The transferability of structure–property relationships for laser-pretreated
metal adhesive joints to laser-pretreated metal–carbon-fiber-reinforced plastic
(CFRP) bonds was investigated. Single-lap shear tests were performed on hybrid
AW 6082-T6–CFRP specimens pretreated with the same pulsed laser surface parameter
sets on the metal surface as previously tested, AW 6082-T6–E320 metal adhesive
joints. The fracture surfaces were characterized to determine the type of failure
and elucidate differences and commonalities in the link between surface structures
and single-lap shear strengths. Digital image analyses of the hybrid specimens’
fractured surfaces were used to quantify remaining CFRP fragments on the metallic
joint side. The results indicate that high surface enlargements and the presence
of undercut structures lead to single-lap shear strengths exceeding 40 MPa and
35 MPa for unaged and aged hybrid specimens, respectively. Whereas for the metal–polymer
joints, the trend from high strength to weakly bonded specimens is largely continuous
with the degree of surface structuring, hybrid metal–CFRP joints exhibit a drastic
drop in joint performance after aging if the laser-generated surface structures
are less pronounced with low surface enlargements and crater depths. Surface features
and hydrothermal aging determine whether the specimens fail cohesively or adhesively.

text: A parameter investigation for manufacturing a hybrid system through the prepreg
pressing process was carried out within the scope of this work to achieve optimal
adhesion properties. The hybrid specimen comprises an aluminium sheet of alloy
EN AW 6082 in T6 condition and a thermoset Carbon Fibre Reinforced Plastics prepreg.
The prepreg pressing process allows the curing reaction of epoxy resin and the
joining process to occur simultaneously to avoid an additional bonding process
step. The surface of the aluminium sheet was pretreated in advance using a pulsed
Nd:YAG laser to enhance the bonding properties. In the first step, the shear edge
tests investigated the adhesion properties achieved with different consolidation
(temperature, time and pressure) and laser parameters. Then, 3-point bending tests
were carried out to investigate the influence of the consolidation parameters
on the mechanical properties of the Carbon Fibre Reinforced Plastics-laminate.
In this way, the optimal parameter sets for manufacturing hybrid structures were
determined.

text: This paper introduces an intrinsic manufacturing process of a hat profile
made of laser-pretreated aluminium sheet of alloy EN AW-6082 in T6 condition and
carbon fibre-reinforced plastic (CFRP) prepreg. The resin system used in combination
with CFRP was epoxy resin (EP). Before manufacturing, the laser-pretreated aluminium
sheet and CFRP prepreg were stacked to form a multi-layer composite, which was
pressed simultaneously in one process step. The optimal CFRP layer structure was
calculated in advance using the finite element method. During the forming process,
the curing reaction and the joining of the aluminium sheet and CFRP prepreg will
take place simultaneously. Thus, further joining techniques such as bonding and
riveting could be saved, and a much more efficient process could be achieved.
After manufacturing, shear-edge test was used to characterize the adhesion properties
of the hybrid part.

text: The corrosion behavior of a hybrid material consisting of intrinsically bonded
carbon fiber-reinforced epoxy resin with laser-structured EN AW 6082 metal was
investigated. Particular attention was paid to the effects of the laser-structuring,
surface topography and the contacting. Pristine and hybridized specimens were
corroded in aqueous NaCl electrolyte (0.1 mol/l) using a potentiodynamic polarization
technique and subsequently analyzed using computed tomography, scanning electron-,
light- and laser scanning microscopy. The results show that the corrosive reaction
arises mainly from the aluminum component. Surface pretreatment of the aluminum
resulted in increasing corrosion rates, but showed no influence on the hybrids
corrosion properties. Optical micrographs suggest that the epoxy resin acts as
a sealant preventing galvanic corrosion between the aluminum and carbon fibers
by hindering the diffusion of the electrolyte into the joints. While corrosion
effects were observed locally at the aluminum surface, they were, contrary to
expectations, not enhanced on the hybrid interfaces.
