摘要
Abstract
Polyphenylene oxide (PPO) is a high strength engineering plastic with high melt viscosity,while aramid fibers (AF) is a high-tech fibers with good mechanical performance and smooth surface.Thus,the impregnation effect of AF in PPO matrix is very poor.In order to prepare PPO reinforced by AF composite materials,the surface of the AF can be modifided through the plasma by adding oxygenous groups on the one hand,preparing PPO/nylon 6(PA6) blend to reduce the melting viscosity on the other hand.In this article,polyphenylene oxide/nylon 6 (PPO/PA6) alloy modified by styrene-butadiene copolymer grafted by maleic anhydride (SEBS-MAH) were studied,and the PA6/PPO/SEBS-MAH composite materials reinforced by aramid fiber were prepared.Experimental results show that PA6 can improve the processing property of PPO/PA6 system and reduce the melting viscosity.SEBS-MAH can improve the compatibility of PPO/PA6 blend system,mechanical properties and the glass transition temperature of blend.Aramid fiber (AF) can improve the PA6/PPO/SEBS-MAH mechanical properties and friction properties of blending system.And,the rigidity of the blend system was improved as shown by the Tanδ-temperature curVes.关键词
