%X 碳纤维增强复合材料(CFRP)与传统建筑材料相比性能优异，在建筑结构加固技术中已经十分成熟。目前，碳纤维增强复合材料作为拉索在大跨空间结构及桥梁领域已有应用，由于树脂基体对温度的敏感性，在超过玻璃化温度(Tg)后会软化甚至分解，导致CFRP材料在高温时性能会有所降低，对结构安全性产生不利影响。本文总结了国内外学者对CFRP材料高温下力学性能的试验和研究结论，提出了一些存在的缺陷以及进一步的研究方向，为后续研究提供参考。<br />
Compared with traditional building materials, carbon fiber reinforced polymer (CFRP) has excellent performance, and has been very mature in building structure reinforcement technology. At present, carbon fiber reinforced composites have been used in large-span space structures and bridges as cables. Because of the temperature sensitivity of the resin matrix, it will be softened or even decomposed after exceeding the glass transition temperature Tg, resulting in the reduced performance of CFRP materials at high temperatures, which will adversely affect the structural safety. This paper summarizes the test and research conclusions of domestic and foreign scholars on the mechanical properties of CFRP materials at high temperatures, and puts forward some existing defects and further research directions, providing reference for further research.
