英文摘要	Silicon oxycarbide fibers were prepared from vinyltrimethoxysilane (VTMS), tetraethoxysilane (TEOS) and phenyltrimethoxysilane (PTMS) by sol-gel method. It was found that the carbon content of the silicon oxycarbide fibers can be adjusted from 21.8% to 30.1wt% by change the mole ratio of VTMS, TEOS and PTMS in the precursors. The oxidation resistance of the fibers was impacted by the content and structure of carbon. The oxidation resistance decreased with the increasing content and domain size of the carbon. Silicon oxycarbide fibers prepared with 75%VTMS-25% TEOS showed good oxidation resistance in air at 600 , because a thin and dense silica film was formed on the surface of the fibers, preventing fibers from further oxidation.
