摘　　要：碳纤维复合材料(CFRP)具有高强度、高刚度、低重量以及优良的耐腐蚀性和耐疲劳性等特点,对于改善土木加固工程结构受力具有不可忽视的作用。文章在总结CFRP轻质高强、良好的抗腐蚀性、抗疲劳性、耐候性和施工便捷等特点的基础上,探讨了其在木结构、钢筋混凝土结构和钢结构加固中的应用。研究表明:在木结构加固中,CFRP可以有效提升其承载能力和抗震性能;在钢筋混凝土结构加固中,CFRP不仅能增强结构的抗弯、抗剪能力,还可改善其耐久性;在钢结构加固中,CFRP通过形成新的应力承受层,显著提升了原有结构的性能。随着材料制备和加固工艺技术的不断创新发展,碳纤维复合材料在土木加固工程中具有巨大的潜力和广阔的应用前景。Carbon fiber composite materials have the characteristics of high strength,high stiffness,low weight,and excellent corrosion and fatigue resistance,which play an indispensable role in improving the stress of civil reinforcement engineering structures.On the basis of summarizing the characteristics of CFRP such as high strength,low weight,good corrosion resistance,fatigue resistance,weather resistance,and convenient construction,the article explores its application in the reinforcement of wooden structures,reinforced concrete structures,and steel structures.Research has shown that in the reinforcement of wooden structures,CFRP can effectively enhance their load-bearing capacity and anti-seismic performance;In the reinforcement of reinforced concrete structures,CFRP can not only enhance the bending and shear resistance of the structure,but also improve its durability;In the reinforcement of steel structures,CFRP significantly improves the performance of the original structure by forming new stress bearing layers.With the continuous innovation and development of material preparation and reinforcement technology,carbon fiber composite materials have enormous potential and broad application prospects in civil reinforcement engineering.
