碳/碳复合材料是一类本质上为陶瓷但表现出脆性至假塑性行为的新型工程材料。碳-碳复合材料是一种独特的全碳复合材料，碳纤维嵌入在碳基体中，被称为逆复合材料。由于其优异的热结构性能，碳-碳复合材料被用于特殊应用，如再入弹头，前缘，火箭喷嘴和飞机制动盘，以及一些工业和生物医学应用。多方向碳-碳产品技术是通用的，并提供设计灵活性。本文介绍了多向预制棒和碳-碳工艺技术以及国内的研究和开发活动。还讨论了DRDL的碳-碳产品经验。介绍了碳/碳制动盘液态浸渍工艺技术的发展。进一步的材料特性，热，机械和摩擦学性能的测试结果。
Carbon carbon composites are a new class of engineering materials that are ceramic in nature but exhibit brittle to pseudoplastic behaviour. Carbon-carbon is a unique all-carbon composite with carbon fibre embeded in carbon matrix and is known as an inverse composite. Due to their excellent thermo-structural properties, carbon-carbon composites are used in specialised application like re-entry nose-tips, leading edges, rocket nozzles, and aircraft brake discs apart from several industrial and biomedical applications. The multidirectional carbon-carbon product technology is versatile and offers design flexibility. This paper describes the multidirectional preform and carbon-carbon process technology and research and development activities within the country. Carbon-carbon product experience at DRDL has also been discussed. Development of carbon-carbon brake discs process technology using the liquid impregnation process is described. Further the test results on material characterisation, thermal, mechanical and tribological properties are presented.
