Preparation of Silicon Oxycarbide Glass Fibers by Sol-Gel Method-Effect of Starting Sol Composition on Tensile Strength of Fibers

摘要

Silicon oxycarbide (Si-O-C) glass fibers were prepared by heat-treating the gel fibers drawn from the solution containing tetra-ethyl-ortho-silicate (TEOS), tri-ethoxysilane (HTES) and methylo-tri-ethoxysilane (MTES) in the course of sol-gel reaction.
