碳纤维增强碳和碳化硅双基复合材料（C/C-SiC）表现出优异的摩擦学性能，是先进摩擦材料的有希望的候选者。开发了压力渗透/碳化与液体硅渗透相结合的方法来制造 C/C-SiC 复合材料。采用三维针刺法制备碳纤维预制件。在压力渗透过程中，通过用呋喃树脂渗透织物预制件来制备碳纤维增强塑料。然后将碳纤维增强塑料碳化，热解形成多孔碳/碳复合材料。最后，用熔融硅渗透多孔碳/碳，得到C/C-SiC复合材料。该复合材料表现出优异的摩擦性能，包括良好的制动稳定性，平均动态μ为0.38，静态μ为0.50，线性磨损率约为5.6μm循环(-1)。此外，摩擦表面覆盖有厚度约10μm的摩擦膜。这些结果表明，C/C-SiC 制动复合材料是先进制动和离合器系统的有希望的候选材料。 (C) 2010 Elsevier Masson SAS。版权所有。
Carbon fibre reinforced carbon and silicon carbide dual matrix composites (C/C-SiC) show excellent tribological properties and are promising candidates for advanced friction materials. A pressure infiltration/carbonization combined with liquid silicon infiltration was developed for fabricating C/C-SiC composites. The carbon fabric preform was fabricated with the three-dimensional needling method. In the pressure infiltration process, the carbon fibre reinforced plastic was prepared by infiltration of the fabric preform with the furan resin. Then the carbon fibre reinforced plastic was carbonized which was pyrolysed to form a porous carbon/carbon composites. Finally, the porous carbon/carbon was infiltrated with molten silicon to obtain C/C-SiC composites. The composites exhibit excellent friction behavior, including a good stability of brake, and the average dynamic mu is 0.38 and static mu is 0.50, in combination with the linear wear rate of about 5.6 mu m cycle(-1). Moreover, the friction surface was covered with friction film which is about 10 mu m in thickness. These results show that the C/C-SiC brake composites are promising candidates for advanced brake and clutch systems. (C) 2010 Elsevier Masson SAS. All rights reserved.
