Production of an Interphase Coating of Polycarbosilane and Rolivsan Ceramic-Forming Compounds on Carbon Fiber

Аннотация

The conditions for depositing a ceramic-forming compound interphase coating on carbon fibers were investigated. Use of polycarbosilane and Rolivsan ceramic-forming compounds in hexane (<3 mass%) and polymer derived ceramic infiltration in an inert medium produced according to the optimal regime based on thermal kinetic calculations an even interphase coating that increased the thermal-oxidation resistance of the starting carbon fibers. The combustion products of carbon fibers with the deposited interphase were hollow SiO₂ structures.
