摘要:
在华东地区自然暴露环境条件下,对土木工程加固常用的2种碳纤维增强复合材料(CFRP)片材共40个试件进行自然老化3 a的耐久性能试验.考察碳纤维片材的抗拉强度、弹性模量、伸长率等主要的力学性能指标随老化时间的变化.结果表明,随着老化时间的延长,两种片材的抗拉强度和伸长率均略有降低,并且其伸长率的变化趋势与抗拉强度的变化趋势类似; 随着老化时间的延长,两种片材的弹性模量变化不大.
Abstract:
The durability of two kinds of common carbon fiber reinforced plastic(CFRP) sheet is investigated under natural environment in East China.Based on the 3a aging experiment of 40 sheets,the variation of the tensile strength,elongation ratio and elastic modulus of CFRP sheets to time is tested.The results indicate that as the increase of time,elongation ratio of CFRP sheets and tensile strength decrease,elastic modulus varies slightly.
