由玻璃和碳纤维制成的复合材料已经彻底改变了许多行业。复合材料的需求正在快速增长，全球需求预计将翻一番。随着复合材料需求的增长，废物管理显然将成为企业的一个重要问题。从技术上讲，复合材料由于其成分的异质性而引发了困难的回收挑战。由于目前复合材料的废物管理实践主要以垃圾填埋为主，政府和企业本身预见到这种情况在未来需要改变。复合材料的回收将在未来发挥至关重要的作用，特别是对于航空航天、汽车、建筑和船舶领域。这些行业将根据现行立法的合规性、商业模式以及成本效益，要求其产品采用不同的回收方案。为了能够评估复合材料的废物管理策略，根据技术准备水平和废物管理层次结构对回收技术进行了审查。本文分析了 56 个研究项目，以确定复合材料回收技术的增长趋势，其中热解、溶剂分解和机械研磨是最突出的技术。这些回收技术在废物管理层次（回收或再利用应用）上获得了高分，表明作为复合垃圾填埋的未来可行替代方案的潜在发展潜力。研究得出的结论是，回收作为废物管理策略是最受欢迎的探索领域。研究发现机械研磨对于玻璃纤维应用最为成熟，而热解对于碳纤维应用最为成熟。该文件还强调需要了解回收材料的使用，将其作为回收工作的重要评估要素。本文有助于扩大和系统化有关复合材料回收技术成熟度和理解的知识。 (C) 2015 年作者。由爱思唯尔有限公司出版
Composite materials made of glass and carbon fibres have revolutionised many industries. Demand for composites is experiencing rapid growth and global demand is expected to double. As demand for composites grows it is clear that waste management will become an important issue for businesses. Technically composite materials evoke difficult recycling challenges due to the heterogeneity of their composition. As current waste management practices in composites are dominated by landfilling, governments and businesses themselves foresee that this will need to change in the future. The recycling of composites will play a vital role in the future especially for the aerospace, automotive, construction and marine sectors. These industries will require different recycling options for their products based on compliance with current legislation, the business model as well as cost effectiveness. In order to be able to evaluate waste management strategies for composites, a review of recycling technologies has been conducted based on technology readiness levels and waste management hierarchy. This paper analyses 56 research projects to identify growing trends in composite recycling technologies with pyrolysis, solvolysis and mechanical grinding as the most prominent technologies. These recycling technologies attained high scores on the waste management hierarchy (either recycling or reuse applications) suggesting potential development as future viable alternatives to composite landfilling. The research concluded that recycling as a waste management strategy is most popular exploration area. It was found mechanical grinding to be most mature for glass fibre applications while pyrolysis has been most mature in the context of carbon fibre. The paper also highlights the need to understand the use of reclaimed material as important assessment element of recycling efforts. This paper contributes to the widening and systematising knowledge on maturity and understanding composites recycling technologies. (C) 2015 The Authors. Published by Elsevier Ltd.
