FOR 2021: Acting principles of Nano-Scaled Matrix Additives for Composite Structures

Carbon fibre reinforced composites are well established for high performance applications in lightweight constructions. The interphase between load-bearing fibre and load-mediating polymer matrix has been optimized in countless studies over the past decades. The research of DFG-project FOR2021 initially approached macroscopic issues such as stiffness, crack resistance
and shrinkage behaviour during curing which could not be improved without nanotechnology.

The used boehmite (AlOOH) nanoparticles enabled a comprehensive material design by modifying the surface properties with adsorbates and selectively bound molecules. Experiments and simulations on different size scales identified and implemented various new construction principles for the boehmite reinforced epoxy matrix, including controlling the curing reaction and especially network formation. An intelligent material design became accessible which reproducibly generates improved property profiles.

The members of the research group FOR 2021 cordially invite you to a scientific dialogue. We look forward to your contributions and suggestions.
