聚合物基碳纤维复合材料废弃物的几种处理方法分析

从环保和可持续发展角度出发,并结合我国碳纤维(CF)生产与使用实际情况,对聚合物基碳纤维复合材料(CFRP)废弃物处理必要性作了较为详尽的阐述。根据CFRP废弃物种类,提出了机械材料再循环法、材料再循环与能量回收法、能量回收焚烧法三种可行处理方法,并从处理费用、环境影响、替代用途三方面对多种处理方案进行了合理评估。综合考虑处理环境影响、经济效益及替代物使用性能等因素,材料再循环与能量回收法为处理CFRP废弃物最合适的方法。此外,为推进其后期处理工作的顺利进行,还从内部、外部因素两方面提出相关建议。

Analysis of Treatment Methods for Carbon Fiber Reinforced Polymer Composite Wastes

Considered environmental protection,sustainable development,and actual production and applications of carbon fibers(CAs) in our country,the necessity of carbon fiber reinforced polymer composite(CFRP) waste treatment was described in details.According to the category of CFRP wastes,three treatment methods including enginery material recycling,material recycling & energy recovery and energy recovery by incinerating CFRP wastes were put forward.And some kinds of the possible treatment projects were evaluated reasonably from three aspects including treatment expenses,environmental impact and substitute use.Comprehensively considering environment impact and economic efficiency,the performance of substitute products,the material recycling & energy recovery is the best method in present stage.In addition,in order to push forward the later polymer composite waste treatment work,related suggestion was set forth from both inner factors and external factors.
