CFRP筋拉伸强度预测模型评价及应用
Evaluation and Application of Tensile Strength Prediction for CFRP Bars
摘要
Abstract
Based on the prediction formula of tensile strength for CFRP bars,weight of influence of the typi-cal factors on material strength was evaluated,and the mechanism of intensity compensation in the process of preparing CFRP bar was proposed.The results show that the effect of typical factors of carbon fiber tensile strength and volume fraction effect on the tensile strength of CFRP bars is most significant (influence rate:39.1%-46.7% and 43.5-52.6%).They are the most important factors that determine the tensile properties of CFRP bars.Nominal diameter has a certain effect on the tensile strength of CFRP bars (influence rate:7.1%-15.4%).Influence of resin matrix strength on the tensile strength of the CFRP bar is not obvious (in-fluence rate:0.3%-1.0%).Compared to the other three factors,the influence of the tensile strength of resin can be nearly neglected.According to the intensity compensation rule of the typical factors,the strength and volume fraction of carbon fiber in CFRP bars can be easily inferred.关键词
