摘要
对碳纤维(CFRP)与玻璃纤维(GFRP)两种应力—应变线性材料在不同比例、不同概率分布等情况下混合后的延性进行了分析,并得出影响CFRP与GFRP混合材料延性的因素。其中纤维强度、单丝极限应变分布概率以及两种材料的峰值应力差和其对应应变差值对混合后材料的应力—应变全曲线形状影响较大。该材料的使用可以克服单一FRP材料在加固中的弊端。
To eliminate the defect of single fiber FRP in reinforcement, by analyzing the ductility of the synthetic fabric of CFRP and GFRP, which stress is linear with strain, in different proportion or different prob(ability) density, the factors that affect the ductility of the synthetic fabric were presented. Among them, the fiber strength, the probability of fiber ultimate strain, the gap of peak stress and the corresponding strain have great influence on the stress-strain curve from synthetic fabric.
