Abstract

The properties of heat-resistant polymer fibers (Arimid, PFBT) and samples of organoplastics based on them have been investigated. It has been established that polyimide and polybenzazole fibers can be used as a reinforcing filler to create organoplastics at operating temperatures up to 350‒400 °C. The level of retention of the elastic modulus in bending of organoplastics based on PFBT fiber and IP-5 heterocyclic binder is 90 %. Heat-resistant organoplastics are promising for use in the aerospace industry and mechanical engineering.
