1.前言随着汽车的高速化和大型化,对制动器性能的要求越来越高。制动器性能与它本身的结构以及这一摩擦副的材料有关,而在很大程度上依靠摩擦片的材料。所以,研制了多种摩擦片,但绝大多数是以石棉为主要成分,加入各种提高摩擦性能的添加剂,与树脂一起制成。在摩擦片的使用范围内,要求摩擦力稳定而且大、耐磨性好、并且质量稳定。但是,含有这类有机物的材料具有难以解决的特性——那就是通常当温度升高时,摩擦力要发生复杂的变
1. Introduction With the high-speed car and large-scale, the brake performance requirements are getting higher and higher. Brake performance and its own structure and the friction of the material, but to a large extent depends on the friction plate material. Therefore, developed a variety of friction plates, but the vast majority of asbestos as the main ingredient, adding a variety of additives to improve friction performance, made with the resin together. Friction within the scope of the use of friction required stability and large, good wear resistance, and the quality and stability. However, materials containing this type of organics have hard-to-come-to-do properties - that is, usually when the temperature rises, the friction forces are complicated
