摘　　要：近些年,随着CFRP(碳纤维增强复合材料)材料技术的不断完善,加上其强度高、防水性强、耐腐蚀性强、自重轻、柔性好等特性,该种新材料开始逐渐运用于古建筑木结构的加固修缮上(例如留园曲溪楼的加固修缮、南京甘熙故居的加固维修)。然而国内外学者对CFRP加固木结构的研究基本都是针对其力学特性,往往忽视了CFRP材料对于木材自身特性的改变所带来的影响,笔者通过研究CFRP材料对木材含水率的影响及其所带来的危害,对CFRP材料在古建筑木结构保护领域的适用性提出质疑,以期研究人员未来在新材料的选择上能更加审慎。Recently the growing development of CFRP(carbon fiber reinforced Polyme)technology and CFRP’s excel ent features as high-quality,good-waterproof,better chemical resistance,light weight and goodflexibility make this new material applied to strengthen and repair ancient wooden structures(such as Zigzag Stream Tower in Lingering Garden and Former Residence of Ganxi in Nanjing).However,domestic and foreign scholars’research basically focuses on the mechanical property of CFRP rather than the influence of CFRP on the change of wood.The author questions the suitability of CFRP in protecting ancient wood structures by studying the impact of CFRP on wood moisture gradient and its harm to the timber in order to remind researchers of choosing repair materials carefully.
