Heat-resistant coreless silicon carbide fibres for composite materials with ceramic and metallic matrices

An original method of synthesis of fibre-forming polycarbosilane was developed. A study of the physicochemical properties of samples of Japanese and our polycarbosilane demonstrated their identity.

Description
Summary:An original method of synthesis of fibre-forming polycarbosilane was developed. A study of the physicochemical properties of samples of Japanese and our polycarbosilane demonstrated their identity. Manufacture of coreless silicon carbide fibres was investigated. The conditions were developed and samples of fibres with a strength of up to 2.5 and a modulus of elasticity of 180 GPa were made. It was found that the physicomechanical properties of our fibres are on the level of mass-produced Japanese fibres and their structural and thermal characteristics are identical.
