A successful, energy efficient and thus economical realization of lightweight structures, whether based on light metals such Al, Mg or Ti or fiber-reinforced composites, is one of the prerequisites for reducing energy consumption, whether in arespace, automotive or architecture. Within that context, fiber-reinforced composites play a crucial role. However, in order to become successful, they require both cheap high performance fibers and fast curing thermo- or duroplastic high-performance matrices and, last but not least, a fast processing technology that brings both parts together. As to fibers, carbon fibers, glass, oxide and non-oxide ceramic fibers as well as poly(aromatic) fibers are in the center of interest. There, current research focuses on cheaper production rechnologies and, for carbon fibers, cheaper progenitors (precursors). In terms of production technologies, modern multi-filament wet-spinning technologies, e.g. those based on ionic liquids, offer access to unprecedented fiber dimensions and properties, e.g. to supermicrofibers < 5 μm in diameter. This presentation will outline current highlights in both carbon and ceramic fiber research as well as in (dry) wet spinning of cellulosic precursors for high-end applications.
