碳纤维复合材料回收及利用现状

Recycling and Reuse of Carbon Fibre Composites

由于碳纤维复合材料具有的强度高、模量高及耐腐蚀性能好等特性,导致其废弃物的处理和利用存在很大难度,碳纤维复合材料废弃物对环境的污染已引起广泛关注。本文概述了碳纤维复合材料废弃物回收的预处理,化学回收、物理回收和能量回收技术,以及国内外碳纤维复合材料废弃物回收及利用现状,指出了碳纤维回收及利用不仅可以实现高价值材料的再利用,而且碳纤维复合材料部件回收及利用可大大减少能源消耗和环境污染。

It is difficult to deal with and make use of the waste of the carbon fibre composites for its the high strength and good corrosion resistance performance, and wide attention has been attracted by the waste of carbon fiber composites. In this paper, the pretreatment of the waste of carbon fiber composites, chemical recycling, physical recycling and energy recycling technology, and the recycling and utilization the waste of carbon fiber composites in global field are summarized. It is pointed out that the recycling and utilization of carbon fiber can not only realize high value material reuse, but also can reduce the energy consumption and environmental pollution.
