摘要：The precursor composition of silicon carbide fibers provided by the inventionhas greatly improved spinnability and can be spun at a very high spinning velocity to givea green filament which has a much larger tensile strength than those of conventionalprecursor materials and is capable of giving silicon carbide fibers having increased tensilestrength by the infusibilization and calcination of the green filament of the compositionunder tension. The composition comprises from 80 to 99.9 parts by weight of a
polycarbosilane polymer and from 20 to 0.01 part by weight of a silmethylene polymerhaving a degree of polymerization larger than the specified lower limit.
