摘　　要：研制了半金属树脂基摩擦材料替代石棉摩擦材料,对其摩擦学等性能进行了研究,并在进口掘进机上进行了试用。结果表明:半金属摩擦片的摩擦因数在0 .362～0 .392之间,变化平稳,在2 5 0℃以上高温热衰退少;耐磨性在2 0 0℃以下时略低于石棉摩擦片材料,而在2 0 0℃以上时与石棉摩擦片材料相当;强度性能达到了原石棉摩擦片材料的技术性能指标。装机试验表明:所研制的摩擦片磨损总量最小。A semi-metallic phenolic resin-based friction material was developed for friction facing on clutch Disc in Tunnel entry-driving machines.The friction coefficient of the developed material is between 0.362~0.392 with good stability and low degradation at more than 250 ℃.Under 200 ℃,the wear loss is lower than that of asbestos materials and over 200 ℃ is equal to it.The strength properties is equivalent to that of asbestos material.The developed friction plates are used in Tunnel entry-driving machines with small wear loss and suitable for clutch Disc under normal or in slipping conditions.
