Abstract: In this paper,the authors first analysed the necessity of making a study of aon-e,s-betos friction materials in China right now and the most important point is to select a suitable reinforcement system, After taking a brief review of foreign country researchers' work,the authors ha ve tested the concerned prop;rtics of a srics of non-asbestos friction m aterials w hick used non-asbestos reinforcements such as glass fiber,carbon fiber,organic fiber,Kevlar,steel f fiber and mineral fiber.The testing results have shown that the most suitable non-asbestos reinforcement systems in China in recent years are‘glass fiber with modified matrix,pre-oxidized carbon fiber and hybrid fiber system with silicate fiber.
