滑动方向对编织复合材料摩擦磨损性能的影响
Effect of sliding direction on friction and wear properties of braided composites
摘要
Abstract
In order to improve the anti-friction and wear performance of three-dimensional braided composites,the effects of the microstructure of the braided composites in the transverse and longitudinal directions on their friction and wear performance were investigated,the process parameters of the braided composites were optimized,and the composites were analyzed for their hardness,thermal conductivity,and wear surface morphology in different di-rections.The results show that the percentage of carbon fiber area in the transverse section of the braided com-posites is lower than that in the longitudinal direction,and their hardness and thermal conductivity in the trans-verse direction are higher than that in the longitudinal direction.When the fiber volume fraction is increased from 0 to 57.5％,the average friction coefficient of the transverse direction of the composites decreases by 34.37％and the wear rate by 99.36％,and the friction coefficient of the longitudinal direction decreases by 31.29％and the wear rate by 98.95％.The stability of the friction coefficient in the transverse direction of the composites is the highest at a fiber volume fraction of 57.5％,while the stability of the friction coefficient in the longitudinal direc-tion is the highest at a fiber volume fraction of 50.5％.The degree of damage on the transverse and longitudinal wear surfaces of the braided composites decrease with increasing fiber volume content and the quality of the lu-brication film increases.关键词
