Appliion of electron beam curing for silicon …

A SiC fiber was synthesized from polycarbosilane-polyvinylsilane (PCS-PVS) blend polymer with electron beam curing under vacuum. The SiC fiber obtained from the blend polymer which contains 20 wt% of PVS in PCS was very fine and flexible, and its average diameter was 7 μm. Although the yield of the SiC fiber from the blend polymer was 73%, that is lower than that of 82% from PCS, with the
