摘要
用热塑性聚(氧-1,4-亚苯基磺酰基-1,4-亚苯基)(聚醚砜)树脂作粘接剂,制备耐高温摩阻材料,探索了材料的压制工艺。试验证实了:聚醚砜树脂和制成的摩阻材料,其耐热性和摩擦磨损性能,较大程度优于改性酚醛树脂和其制成的材料。通过近代表面分析手段对摩擦表面和磨屑进行了分析,并探讨了其磨损机理。
Employing thermoplastic poly(oxy-1, 4-phenylene sulfonyl-1, 4-phenylene)(polyethersulfone or PES in brief) resin as binder, friction materials for high temperature services were fabricated. The technology of compression moulding was explored. Tests confirm that the heat-resisting and tribological properties of the PES resin and the friction materials there of are to a great extent better than those of the modified phenolic resin and the friction materials there of. With the aid of modern surface analytical tools, the surfaces before and after rubbing as well as the wear debris were investigated and the wear mechanism was discussed accordingly.
