Abstract (english): Fiber-reinforced composites have superior properties compared to conventional structural materials. They already gain a very high standard, resulting in application in the aerospace and other important industries, however, there is still room for further improvement. These aim toward manufacturing, cost reduction during material processing, application, and last but not least superior material properties.Nanocomposites (polymers filled with nanoparticles as carbon nanotubes, graphene, etc.) have been under investigation in the last decade and they resulted in tremendous improvements in mechanical properties, as fracture toughness or electrical conductivity.Nanocomposites used as matrix for fiber-reinforced polymers (FRPs) have the potential to improve overall mechanical properties as interlaminar shear stress, first-ply failure, impact and compression after impact, etc. At the same time, the polymer matrix being an isolator by nature can be turned into an electrically conductive material. This additional function can not only be used for electric charge ablation but also be used for sensing deformation and/or damage. Especially, their potential for strain sensing applications with electrical conductivity methods can be used to investigate the electromechanical response of nanocomposites or FRP deformation when subjected to mechanical load.An integration of carbon nanoparticles into the matrix of FRPs not only improves the overall properties, they turn into a multifunctional material. Superior mechanical properties combine with sensing capabilities. Composite materials can even better compete with conventional structural materials, respectively, are an even more attractive alternative.
