摘　　要：本文通过管状C/C复合材料的3D模型,推导出纤维体积分数的计算公式。用有限元分析软件对管状C/C复合材料进行了温度场模拟。并在此基础上,对不同温度载荷下温度分布情况进行了分析。结果表明,管状C/C复合材料其传热能力能够满足不同温度载荷条件下的传热要求。此法还可以进一步完成在不同温度载荷下管状C/C复合材料的热应力分析。Through a three-dimensional model of braided tubular carbon/carbon composites in this text a formula of fiber volume fraction was developed.Temperature field was analyzed through finite element method and simulated by finite element analysis software.It indicated that the heat-transfer capability of braided tubular carbon/carbon composites can meet the requirement of heat transfer by the analysis of temperature field with different temperature loads.Furthermore,thermal-stress analysis can also proceed by the method.
