摘　　要：研究了三元乙丙橡胶/乙烯基硅橡胶泡沫材料的力学性能,并表征了泡沫的摩擦性能。实验结果表明,随着乙烯基硅橡胶的含量增加,泡沫材料的硬度、拉伸强度和压缩模量呈下降的趋势,而静摩擦系数先下降后轻微上升;随着正压力和温度的升高,橡胶泡沫材料的静摩擦系数逐渐减小;随着硫化剂用量的减小和操作油用量的增加,橡胶泡沫的静摩擦系数上升。The mechanical and friction properties of the foam materials of ethylene propylene diene terpolymer/ vinyl silicone rubber blend were studied. The results show that, while the vinyl silicone rubber content increasing, the hardness, tensile strength and compressive modulus at break of the rubber foams were decreased, the coefficient of friction （COF） was initially reduced, and then increased. While the testing temperature and pressure increasing, the COF of the foam materials reduced. The COF of the foam materials increased while the dosage of processing oil in- creasing and curative reducing.
