text: The use of hybrid materials as a combination of fibre-reinforced plastic (FRP)
and metal is of great interest in order to meet the increasing demands for sustainability,
efficiency, and emission reduction based on the principle of lightweight design.
These two components can therefore be joined using the intrinsic joining technique,
which is formed by curing the matrix of the FRP component. In this study, for
the hybrid joint, unidirectionally pre-impregnated semi-finished products (prepregs)
with duromer matrix resin and micro-alloyed HC340LA steel were used. In order
to conduct a detailed investigation, the damage mechanisms of intrinsically produced
fibre metal laminates (FMLs), a new clamping device, and a novel pressing tool
were designed and put into operation. The prepregs were prestressed by applying
a preloading force using a specially designed prestressing frame. Hybrid specimens
were then produced and subjected to nanoindentation and a shear tensile test.
In particular, the effect of the residual stress state by varying the defined
prestressing force on the damage mechanisms was studied. The results showed that
no fracture patterns occurred in the interface of the specimens without preloading
as a result of curing at 120 °C, whereas specimens with preloading failed at the
boundary layer in the tensile range. Nevertheless, all specimens cured at 160
°C failed at the boundary layer in the tensile range. Furthermore, it was proven
that the force and displacement of the preloaded specimens were promisingly higher
than those of the unpreloaded specimens.

text: The utilization and preparation of functional hybrid films for optical sensing
applications and membranes is of utmost importance. In this work, we report the
convenient and scalable preparation of self-crosslinking particle-based films
derived by directed self-assembly of alkoxysilane-based cross-linkers as part
of a core-shell particle architecture. The synthesis of well-designed monodisperse
core-shell particles by emulsion polymerization is the basic prerequisite for
subsequent particle processing via the melt-shear organization technique. In more
detail, the core particles consist of polystyrene (PS) or poly(methyl methacrylate)
(PMMA), while the comparably soft particle shell consists of poly(ethyl acrylate)
(PEA) and different alkoxysilane-based poly(methacrylate)s. For hybrid film formation
and convenient self-cross-linking, different alkyl groups at the siloxane moieties
were investigated in detail by solid-state Magic-Angle Spinning Nuclear Magnetic
Resonance (MAS, NMR) spectroscopy revealing different crosslinking capabilities,
which strongly influence the properties of the core or shell particle films with
respect to transparency and iridescent reflection colors. Furthermore, solid-state
NMR spectroscopy and investigation of the thermal properties by differential scanning
calorimetry (DSC) measurements allow for insights into the cross-linking capabilities
prior to and after synthesis, as well as after the thermally and pressure-induced
processing steps. Subsequently, free-standing and self-crosslinked particle-based
films featuring excellent particle order are obtained by application of the melt-shear
organization technique, as shown by microscopy (TEM, SEM).
