The Research On Non-asbestos Friction Material Of Resisting Thermal Decay

With development of traffic speed, friction materials were required more and more high, non-asbestos friction material were widely studied. This paper reviews domestic and overseas developments of the non-asbestos friction material, as well as the testing methods and evaluation standards. Some mechanism, such as friction mechanism, wearing mechanism, heat decline mechanism, and heat chap mechanism are series analyzed. After studied the raw materials, non-asbestos fiber, adhesion, friction performance regulator, recipe. The tough and heat-resistant cashew Shell-modified resin was used as adhesive, Steel fiber, Kevlar fiber, FKF fiber was used as non-asbestos fiber and much friction performance regulator in properties were used as main materials, that was employed to produce the non-asbestos friction material. Then in comparison this product to the same kind of product from abroad, the results from the mechanical properties, DMS tester and CHASE tester showed that non-asbestos friction material of complex fiber can be able to improve complex performance, be stable friction performance, resist decay and reduce wearing rate and of materials obviously. For its environmental protection, safety and wearing-resist, this product is a desirable non-asbestos friction material and it has a splendid market in the future.
