通过对比分析Dunlop、B.F.Goodrich、Missier、Bendix和中南大学粉末冶金研究所制备的几种炭/炭复合材料的显微组织、石墨化度、导热系数、洛氏硬度、抗压、抗弯、层间剪切强度、摩擦磨损性能后,得出如下结论:C/C复合材料作为一种性能优良的制动材料,必须具有合理的炭纤维骨架结构,一定比例的粗糙层气相沉积炭结构,较高的石墨化度和垂直摩擦面方向上的导热系数;我国具有自己知识产权的C/C复合材料飞机刹车盘的研制工作已取得了较大的进展和突破,其各项性能指标与国外同类产品性能相当。
Through comparative analysis of the microstructure, graphitization degree, thermal conductivity, Rockwell hardness, compressive strength, bending resistance and hardness of several carbon / carbon composites prepared by Dunlop, BF Goodrich, Missier, Bendix and Central South University Institute of Powder Metallurgy Interlaminar shear strength, friction and wear properties, the following conclusions are drawn: C / C composites as a good braking material must have a reasonable carbon fiber skeleton structure, a certain proportion of rough layer vapor deposition of carbon structure, compared with High graphitization degree and thermal conductivity in the direction of vertical friction surface. The development of C / C composite brake discs has made great progress and breakthrough in China with its own intellectual property rights. Product performance is quite.
