碳纳米材料接枝碳纤维的复合材料界面增效研究进展

摘要/Abstract

摘要： 界面作为复合材料的重要组成部分,起着传递载荷的作用,影响复合材料的整体性能。碳纤维表面属于石墨乱层结构,微晶有序取向,惰性大,不易与树脂基体结合。对碳纤维进行适当的表面改性,增加纤维的比表面积、粗糙度和引入活性官能团,都能改善表面润湿情况,实现机械结合和化学结合,提高复合材料的界面性能。碳纳米材料接枝到碳纤维表面,是提高界面性能的有效方法之一。因此,对碳纳米管、氧化石墨烯接枝碳纤维的制备方法、界面增效设计以及界面增强机制的国内外研究现状进行综述和分析,在此基础上,展望了碳纳米材料接枝碳纤维表面和界面性能评价方法的研究趋势和前景。

Abstract: Interface, as an important component of composite materials, acts as a transfer load, and affects the overall properties of composites. The surface of carbon fiber belongs to graphite disordered structure, and the crystallite is orderly and inert. Therefore, it is difficult for it to combine with the resin matrix. Increasing the specific surface area, the roughness of the fiber or introducing active functional groups to the fiber can improve the surface wettability, mechanical and chemical combination and improve the interface properties of composite materials. The grafting of carbon nanomaterials onto the surface of carbon fibers is one of the effective methods to improve the interfacial properties. In this paper, the preparation methods of grafting carbon nanotubes and graphene oxide onto carbon fibers, interface design and interface enhancement mechanism were reviewed and analyzed. The development trends and prospects of grafting carbon nanomaterials onto carbon fibers and interface performance evaluation methods also were discussed.

Key words: carbon fiber, carbon nanomaterials, interface, micro/nano structures
