不同胶粘剂含量下摩阻材料冲击韧性和硬度对摩擦学性能的影响

Effect of Impact Toughness and Hardness of different Adhesive Weight on Tribological Property of Frictional Materials

纤维增强摩阻材料的抗冲击韧性和硬度对摩擦学性能有一定影响,但并不惟一决定摩擦系数和磨损率的大小。在胶粘剂含量为25％时,硬度有最大值为88.13(HRL),在胶粘剂含量为28％时,无缺口冲击韧性有最大值为4.68kJ/m^2,在胶粘剂含量较低时,硬度对摩擦性能起主要作用;在胶粘剂含量较高时,冲击韧性对摩擦性能起主要作用。

Impact strength and hardness have effects on the tribological property; but they don't uniquely depend on wear rate and coefficient. Maximal hardness of frictional materials is 88. 13(HRL) when adhesive weight is 25% and maximal impact strength is 4. 68kJ/ m2 when adhesive weight is 28%. Hardness plays a main role when adhesive weight is lower, on the other hand, impact toughness plays a major role when adhesive weight is higher.
