Polyimide fiber is a polymer material with good heat resistance. It has a variety of excellent physical properties. It is one of the highly favored high-tech fibers in the fields of aerospace, radiation protection materials, and high temperature resistant chemical materials. The Russian Institute of Polymer Chemistry used polyimide crystals, nano-carbon fibers, and carbon microfibers to produce composite materials (carbon plastics).
Polyimide can be crystallized from the melt, and the crystal structure can improve the heat resistance, water resistance and alkali resistance of the material. Study of adhesives using 1,3-bis-(3,3,4,4-dicarboxyphenoxy)benzene and 4,4-bis-(4-aminophenoxy)-diphenyl as composite materials . Polyimide crystals, binder particles, modified nano-carbon fibers produced in Japan (content 3%), Russian-made “Aurolu” carbon microfibers (content 55%), made of composite materials under laboratory conditions . The duration of the polyimide crystals in the experiment was only one-tenth of the usual, the interlaminar fracture toughness of the composites increased, and the crystallinity of the composites reached 40%. The study was funded by the government of the Russian Federation.
