文档介绍：The particle was evenly dispersed in the adhesive at proper mass fractions with the assistance of ically and ultrasonic stirring. 采用磁力搅拌和超声搅拌的方法将纳米颗粒添加到树脂溶液中。 Then, the carbon fabric after pre-treatment (the carbon fabric was dipped in acetone for 24h and boiled in distilled water for 10 min, followed by cleaning with acetone in an ultrasonic bath) was immersed in the mixed adhesive to allow the coating by the adhesive mixture containing the filler 碳布首先在丙酮中浸泡 24 小时后在去离子水中清洗 10 分钟, 然后浸渍到溶液中。 The anic nano-particles, such as TiO2, ZnO, SiO2, and Si3N4 could be of significance in this respect, since they as the fillers were reported to be effective in improving the friction and wear properties of some polymer and posites [11,14 – 18], owing to their specific properties, such as high surface activity and energy and small size effect. At the same time, the F-containing polymers, such as PTFE [11,19] and PFWas the fillers were also found to be effective in modifying the friction and wear behaviors of some posites or posites [11]. Therefore, nano-ZnO, nano-SiC and PFW were selected as the fillers to modify the carbon posites in the present work. The fabrication process of the posites is illustrated in . First, fresh PAN-based CF supplied by Taiwan Carbon Technology Co., Taiwan, was used as matrix, which was coated with SiO2 nanoparticles. The fabric has a thickness of – m
