本文从C/C复合材料的原材料入手,研究了基体添加剂及碳纤维表面处理对C/C复合材料高温抗氧化性能的影响,结果表明,在C/C复合材料复合成型之前,在基体中增添抗氧化物质及对碳纤维进行表面处理都能改善高温抗氧化性能,并在实践中发现,碳纤维用量也与C/C复合材料的高温抗氧化性能有一定关系。 In this paper, starting from the C / C composites raw materials, the matrix additives and carbon fiber surface treatment on the C / C composites high temperature oxidation resistance, the results show that before the C / C composites composite molding, add matrix Oxidizing substances and carbon fiber surface treatment can improve the high temperature oxidation resistance, and in practice found that the amount of carbon fiber with the C / C composite high temperature oxidation resistance have a certain relationship.
