In this study, the cashew nut shell oil modified phenolic resin based friction materials reinforced by aramid pulp/glass/carbon fibres (constant content 17 vol.%) are prepared by hot pressed sintering method, and the effect of different fibres on tribological properties of resin matrix materials is studied. The tribological properties of friction materials are carried out by a ring‐on‐block tribo‐tester sliding against AISI 51200 steel ring under different braking loads and speeds. The friction coefficient and wear rate increase with the increase of load and speed. The synergistic effect of aramid pulp fibre and carbon fibre improves the tribological properties of friction materials. However, the friction coefficient and wear rate increase as the glass fibre increases. The specimen with 9%/1%/7% of aramid pulp/glass/carbon fibres shows more reasonable friction coefficient (0.31–0.50) and lower wear rate (4.5–7.9 × 10⁻⁶ mm³ N⁻¹ m⁻¹) than that of commercial friction material.

不同纤维对树脂基摩擦材料的干制动性能

本研究采用热压烧结法制备了由芳纶浆粕/玻璃纤维/碳纤维增强的腰果壳油改性酚醛树脂基摩擦材料（恒定含量为17 vol。％），不同纤维对摩擦学性能的影响。研究了树脂基材料。摩擦材料的摩擦学性能是通过一个在不同制动负载和速度下在AISI 51200钢环上滑动的环上摩擦试验机来实现的。摩擦系数和磨损率随着负载和速度的增加而增加。芳纶纸浆纤维和碳纤维的协同作用改善了摩擦材料的摩擦学性能。但是，摩擦系数和磨损率随着玻璃纤维的增加而增加。^-6  mm ³  N ^-1  m ^-1）。
