The silicon carbide fiber and polycarbosilane fiber developed in 1990 have come up to advanced world standard. They promise wide application in astronautic field sand national economy. detail.

The influences of the fiber substrate pretreatment process and matrix densification methods on the properties of carbon fibers reinforced silicon carbide composites have been investigated.

Polycarbosilance(PC P) is a precursor for silicon carbide(SiC) fiber with good mechanical properties and low specific resistance.
