摩擦材料的应用

摩擦材料的应用

摩擦材料广泛用于各种交通运输工具(如汽车、火车、飞机、舰船等)和各种机器设备的制动器、离合器及摩擦传动装量中的制动材料。在制动装量中，利用摩擦材料的摩擦性能，将转动的动能转化为热能及其他形式的能量，，从而使传动装量制动。　　现代汽车摩擦材料是一类以摩擦为主要功能，兼有.结构性能要求的复合材料。在工作时主要承受反复变化的机械应力场与热应力场，而力与热的发生源是无限形成新工作面的摩擦界面。汽车用摩擦材

摩擦材料理化性能之检测

摩擦材料理化性能之检测

11、吸水（油）率   吸水（油）率，可以反映出摩擦材料结构的致密程度。测定方法：制取5cm*5cm试样后，称其重量及准确测量其几何尺寸，然后放入蒸馏水或者10#机油中，应注意试样在容器中不可接触容器的内壁或贴于容器壁上，试样表面不得有气泡。经浸渍4小时后，取出用纸擦干，并立即称重，要求两分钟之内结束。12、收缩率   摩擦材料同其它物质一样具有热胀冷缩的特性，尤其是经过热压后出模时温度较高，因冷
