摘要
Abstract
Carbon fiber reinforced SiBCN-matrix composites were fabricated by polymer infiltration and pyrolysis route (PIP) with a lab-produced SiBCN precursor (P-SiBCN) as a matrix source.Their mechanical properties were investigated.The composite obtained from 8 PIP-cycles showed its flexure strengths of 334 MPa at room temperature,and in-situ flexure strength of 367 MPa at 800℃ in inert gas atmosphere.The composite retained its 60％ strengths upon bending even at 800℃ in air.关键词
