摘　　要：采用温压?原位反应法制备C/C-SiC复合材料,利用QDM150型摩擦试验机研究短炭纤维(SCF)长度和纤维体积分数对C/C-SiC制动材料摩擦磨损性能的影响。结果表明:C/C-SiC制动材料能够保持较高且稳定的摩擦因数;SCF的体积分数将影响C/C-SiC制动材料的摩擦磨损性能,纤维体积分数为10%时,材料具有适中的摩擦因数和较低的磨损率;SCF长度对C/C-SiC制动材料的摩擦磨损性能有显著影响,炭纤维长度为12 mm时,材料具有最佳的摩擦磨损性能。C/C-SiC composites were manufactured by warm compacted-in suit reacted process. The influence of short carbon fiber length and content on the friction and wear behaviors of C/C-SiC composites was investigated using QDM-150 wear tester. The results show that C/C-SiC composites can keep high and stable friction coefficient. The friction and wear behaviors of C/C-SiC composites are affected by carbon fiber content. When the volume fraction of fiber is 10%, the material has moderate friction coefficient and lower wear rate, The length of carbon fibers significantly influences the friction and wear behaviors of C/C-SiC composites. When the length of carbon fiber is 12 mm, the material has the best friction and wear properties.
