摘要/Abstract

摘要： 采用经典复合材料混合率公式[σ]=σ_fV_f+σ_m(1-V_f)预测国产碳纤维复合材料(CFRP)筋拉伸强度与实测值存在较大误差。本文通过大量实验分析,分别研究复合材料界面粘结性不同,碳纤维、树脂力学性能、体积含量不同,以及复合材料宏观尺寸、形貌差异等对国产CFRP筋拉伸强度及其预测值的离散性影响规律,并对影响因素进行评价。综合试验数据,提出CFRP筋轴向拉伸强度混合率公式修正因子。

Abstract: There are some deviations between the result calculated by the mixing formula of the composite theories ([σ]=σ_fV_f+σ_m(1-V_f)) and the measured value of the tensile strength for carbon fiber reinforced composite (CFRP) rods. Combining with a large number of experiments, the paper studied the evolution of different interfacial adhesion for CFRP rods, different strength and volumes for carbon fiber and plastics, different dimensions and morphology for CFRP rods on the result calculated by the mixing formula of the composite theories and the measured value of the tensile strength for CFRP rods, and evaluated the affecting of these factors. The correction factor for the formula of tensile strength of composite theories mixing rate was put forward.

Key words: composite theories, carbon fiber reinforced composite rods, tensile strength, discrete research
