对目前土木工程加固常用的两种碳纤维片材及树脂耐久性进行了对比性试验研究.截至自然老化3年时,已进行了16组共80个试件的试验.考察在我国自然环境条件下抗拉强度的老化.根据复合材料的中值老化剩余强度半经验数学模型,对其进行拟合,回归出CFRP复合材料及其树脂的剩余强度中值方程的相关参数.预测复合材料自然老化剩余强度.对复合材料进行寿命预估,供进一步研究和工程设计参考使用.
In the current civil engineering reinforcement commonly used two kinds of carbon fiber sheet and the durability of a comparative study of the resin.As of 3 years of natural aging, has been a total of 16 groups of 80 test specimens investigated in our natural environment conditions According to the semi-empirical mathematical model of the median aging residual strength of the composite material, the parameters of the CFRP composite material and the resin residual strength median equation are regressed, and the natural aging residual of the composite material is predicted Strength The composite material life expectancy for further study and engineering design reference.
