再生碳纤维表面处理及其应用

Surface modified and application of recycled carbon fibre

再生碳纤维及其复合材料应用具有很大的环境价值和经济价值。通过制备水性聚氨酯上浆剂并对再生碳纤维进行表面处理,可以有效改善碳纤维表面润湿性,并进一步增强其与热塑性树脂的界面结合。实验结果表明,再生碳纤维经表面改性后,再生碳纤维/ABS树脂基复合材料展现出良好的拉伸强度以及弹性模量。旨在丰富再生碳纤维热塑性树脂基复合材料的相关研究,为后续再生碳纤维表面再构造及其热塑性复合材料制备提供参考依据,有望促进再生碳纤维在工业领域的应用。

The application of recycled carbon fibres and their composite materials have great economic value.The surface wettability of carbon fibres can be effectively improved after modifying of waterborne polyurethane sizing agent.Moreover,the interface integration situation between carbon fibres and thermoplastic resins can be further enhanced.The experimental results show that the surface modified recycled carbon fibre/ABS resin matrix composite exhibits good tensile strength and elastic modulus.This article aims to enrich the relevant research on recycled carbon fibre/thermoplastic resin composites,and provide references basis for the subsequent surface reconstruction of recycled carbon fibres and the preparation of thermoplastic composites.It is expected to promote the application of recycled carbon fibres in the industrial field.
