Novel oxidation-stable carbon-based multifibrillar fibers with exceptional mechanical properties via electrospinning

Project description: Nowadays, carbon fibers are one of the most important engineering fiber types due to their excellent mechanical properties and light weight. Therefore, C-fibers are well established as reinforcements for various composites such as fiber-reinforced plastics and fiber-reinforced ceramics for applications in aerospace, automotive, military, aerospace, construction, wind turbines, as well as medicine and sports. The disadvantage of carbon fibers is the oxidation that already starts at 400 ° C. This DFG project aims to develop the next generation of C-fibers with high thermo-oxidative stability and exceptional tensile strength. The potential of these carbon fibers, which are easy to process in textile technology, for reinforcing plastics and for ceramic reinforcement will also be investigated and evaluated. The necessary complementary expertise for the synthesis and modification of corresponding polymers, their processing into multifibrillar fibers by electrospinning, their curing and pyrolysis is available at the two chairs of Ceramic Materials and Macromolecular Chemistry II at the University of Bayreuth.
