Wear and high–low temperature resistance composites with enhanced mechanical and thermal properties were preparation by carbon fiber (CF) reinforced silicone rubber (MVQ)/fluorine rubber (FKM), the coupling agent was used as a compatibilizer. The effect of coupling agent type and content on mechanical properties of CF/MVQ/FKM composites was investigated, the interaction between coupling agent and composites was studied by infrared spectrum and X-ray photo electron spectroscopy, the surface morphology and phase composition of composites were observed by atomic force microscope and infrared imaging technology, the thermal properties of composites were studied by dynamic thermomechanical analysis and thermogravimetric analysis. The results showed that the coupling agents crosslinked with CF and matrix, the best coupling agent was (3-mercaptopropyl) trimethoxysilane (KH590), and the content was 2 phr (parts per hundred rubber), the wear of KH590/CF/MVQ/FKM composites decreased from 0.0314 to 0.0283 cm3 km−1, the Tg reduced from – 20 to − 34 °C, the initial decomposition temperature increased from 231 to 304 °C compared with FKM.

碳纤维增强硅橡胶/氟橡胶复合材料的磨损和热性能

用碳纤维(CF)增强的硅橡胶(MVQ)/氟橡胶(FKM)制备具有增强的机械和热性能的耐磨和高低温复合材料,并使用偶联剂作为增容剂。研究了偶联剂类型和含量对CF / MVQ / FKM复合材料力学性能的影响,并通过红外光谱和X射线光电子能谱研究了偶联剂与复合材料之间的相互作用,得出了复合材料的表面形态和相组成。通过原子力显微镜和红外成像技术观察,通过动态热力学分析和热重分析研究了复合材料的热性能。结果表明,偶联剂与CF和基质交联,3  km -1时T g从– 20降至– 34°C,与FKM相比,初始分解温度从231°C升高至304°C。
