纺织增强复合材料已成为航空航天、汽车、土木工程和许多其他行业中日益重要的轻质结构关键技术。由于没有合适的碳纤维增强塑料（CFRP）修复程序，损坏的部件必须完全更换;这在生态和经济上都是非常不利的。随着纤维增强复合材料的使用越来越频繁，快速有效的局部修复受损CFRP的方法至关重要。本文提出了一种新的碳纤维复合材料修补方法。通过氧化物半导体的IR辐射的热活化被用来通过维持其结构稳定性和性能来局部降解受损CFRP的热固性基质。然后用热固性环氧树脂基质重新填充无基质纺织品结构。采用扫描电子显微镜、红外光谱仪、热重分析仪对处理后的碳纤维进行了表征，并随后对单纤维的拉伸强度进行了测试，以验证该方法的有效性。© 2015 Wiley Periodicals，Inc.

Textile‐reinforced composites have given rise to an increasingly important key technology for lightweight construction in aerospace, automotive, civil engineering, and many other industries. Because there exists no suitable repair procedure for carbon‐fiber‐reinforced plastics (CFRPs), damaged parts have to be replaced completely; this is extremely disadvantageous both ecologically and economically. With fiber‐reinforced composites used being more and more often, fast and efficient methods for the local repair of damaged CFRPs are essential. In this article, a novel repair procedure for CFRP is presented. The thermal activation by IR radiation of oxide semiconductors was used to locally degrade the thermoset matrix of the damaged CFRP through the maintenance of its structural stability and properties. The matrix‐free textile structure was then refilled with a thermoset epoxy matrix. Carbon fibers from the treated area were characterized with scanning electron microscopy, IR spectroscopy, thermogravimetric analysis, and subsequently, tensile strength for single fibers to verify the effectiveness of the procedure. © 2015 Wiley Periodicals, Inc.
