摘要: 碳纤维增强复合材料(Carbon Fibre Reinforced Polymer,CFRP)在生产、应用与报废的过程中产生的废弃物逐年增多,如何处置该类废弃物已成为一个全球性的难题。本文首先介绍了CFRP目前主要的回收形式与回收方法,然后聚焦于回收CFRP被添加到水泥基材料中的研究现状。现有研究表明加入CFRP对水泥基材料力学性能的改善有明显效果,对其耐高温性以及导电性也有显著提升。这证明了使用回收CFRP开发多功能水泥材料的可能性,为回收CFRP材料开辟了一条新的途径,对于环境保护以及废弃物资源化都有重大的意义。

Abstract: The waste generated by Carbon Fiber Reinforced Polymer (CFRP) in the process of production, application and scrap is increasing year by year. How to dispose of this kind of waste has become a global problem. This paper firstly introduces the main recycling forms and methods of FRP, and then focuses on the up-to-date research of adding recycled FRP to cement-based materials. Existing studies show that the addition of CFRP has an obvious effect on mechanical properties of cement-based materials, as well as the temperature resistance and conductivity. This proves the possibility of using recycled CFRP to develop multifunctional cement materials, which opens a new window for recycling FRP materials, and is of great significance for waste recycling and environmental protection.

Key words: waste CFRP, concrete, cement, mechanical properties
