摘要：

Synthesis of two kinds of polycarbosilane (PCS) with different number average molecular weights and different melting points was done by thermal decomposition and condensation was achieved by polydimethylsililene (PDMS). PCS was melt-spun through trilobal-shaped spinning jets in N2 atmosphere and triobal PCS fibers were thus obtained. Observations of the fibers were made by SEM and it was found that the fiber's degree of profile was unchanged after air curing and heat treatment.
