| 摘 要： | FRP加固广泛应用于土木工程,对耐久性能的研究已得到了工程界的重视。对目前土木工程加固常用的碳纤维片材耐久性进行了初步的试验研究。考察我国西北自然环境条件下老化对其抗拉强度、伸长率和弹性模量等的影响。共完成40个碳纤维片材的拉伸性能试验。截至自然老化2年时,碳纤维片材伸长率略有下降,抗拉强度与弹性模量基本不变。

| Abstract: | FRP strengthening is widely used in civil projects and more attention is paid to its durability.Studies and tests were done on the durability of common CFRP sheets.Influence to strength,extensibility and modulus of CFRP sheets was investigated in nature aging environment of northwest China.Forty sheets were tested and the results indicate that as the increase of time,extensibility of CFRP sheets will decrease and Young's modulus and tensile strength will basically remain a constant. |
