【Abstract】 s Anti-radiation polyetherketone with cardo group(PEK-C)based self-lubrication composite material was prepared with Mos 2, graphite, carbon fiber and Laf 3.The preparation process and properties of the composite material were introduced,and the effect of compositin ratio of several additives on the properties of the composite material were studied.The results showed that the use of graphite and MoS 2to PEK-C could improve the friction-wear properties of the composite material obviously.Not only the use of carbon fiber and LaF 3improved the mechanical properties,but also improved the friction-wear properties to a certain degree.In addition,the use of the mentioned additives improved the anti-radiation property of the composite material.更多还原
