Abstract
A SiC fiber was synthesized from polycarbosilane-polyvinylsilane (PCS-PVS) blend polymer with electron beam curing under vacuum. The SiC fiber obtaine d from the blend polymer which contains 20 wt% of PVS in PCS was very fine and flexible, and its average diameter was 7 mum. Although the yield of the SiC fiber from the blend polymer was 73%, that is lower than that of 82% f rom PCS, with the curing dose of 15 MGy, its yield increased up to 80% with the curing dose of 35 MGy.
