摘　　要：目前碳纤维加固混凝土结构技术的应用越来越广泛,但是由于粘贴碳纤维的有机胶其玻璃态转化温度仅为100℃左右,在火灾下很快就会失去粘结力,使得碳纤维的加固作用丧失,所以对碳纤维加固混凝土结构耐火问题的研究就显得非常重要。通过对国内外相关研究成果进行整理和分析,回顾了碳纤维增强复合材料以及碳纤维加固混凝土结构耐火问题的研究现状,并提出了今后对这一领域的研究趋势,为进一步研究工作的展开提供参考。At present, there has been an increase in the use of the technology of concrete structures strengthened with carbon fibre reinforced polymer （CFRP） . However, because the glass transition temperature （ Tg ） of the organic matrix/ adhesive is only about 100℃, the CFRP- concrete bond strength will be severely degraded in fire, and then the effective of the CFRP strengthening systems will be lost. Therefore, it is very important to study the fire performance of CFRP strengthened reinforced concrete structures. By sorting out and analyzing the relative research results at home and abroad, this paper reviews present research situation of the fire behavior of CFRP and CFRP strengthened reinforced concrete structures, and presents the prospect of future research in this field to provide references for further study.
