摘要
采用热压烧结技术制备桐油改性酚醛树脂和腰果壳油改性酚醛树脂基摩擦片,通过CFT环块摩擦磨损试验机研究其在不同的制动速度、制动正压力下以及在瞬时制动时的摩擦因数以及磨损率的变化规律,采用扫描电镜(SEM)对试样摩擦后的表面形貌进行观察分析。结果表明,2种树脂基摩擦片摩擦因数以及磨损率变化规律具有一致性:摩擦因数均随着制动正压力与制动速度的增加而减小;磨损率随着制动速度的增加而减小,随着制动正压力的增加而增加。以桐油改性酚醛树脂为基体,碳纤维为增强纤维的摩擦片在瞬时制动时具有较稳定的摩擦因数,而且在不同制动正压力与制动速度下磨损率较低。
Two kinds of different resin-based friction plates, the phenolic resins modified with tung oil and modified with cashew nut oil were prepared by hot-pressed sintering technology （P/M）. The friction coefficient and wear rate of the friction plates at the different braking speeds, braking loads and instantaneous brake were studied by using CFT ring-on-block machines, and the worn surface was analyzed by the scanning electron microscopy （SEM）. The results showed that the friction coefficient and wear rate of two kinds of friction plates show that the similar trend, namely the friction coefficient is decreased with the increase of braking speeds and braking loads, and the wear rate is decreased with the increase of braking speeds and increased with the increase of braking loads. The friction plate with phenolic resin modified with tung oil as the matrix, the carbon fiber as the reinforced fiber has stable friction coefficient at instantaneous brake condition and has lower wear rate at different braking load and braking speed.
