摘要
借助显微照相分析系统,对碳纤维复合材料孔隙形态特征进行观察和统计分析。结果表明,复合材料孔隙形态特征与孔隙含量存在着密切关系,孔隙长度特征参数近似呈对数正态分布,并建立了含孔隙形态分布特征的孔隙率超声衰减测试模型。
A morphological study of voids and a statistical study of the voids morphological features in carbon fiber reinforced plastics (CFRP) were implemented using microscopy and image analyzing system. The results show the voids morphological features are correlated with the CFRP porosity and the fraction of voids is nearly a logarithmic normal distribution with the voids size. Based on the study, an ultrasonic attenuation model of CFRP porosity testing was established in which the voids statistical and morpho...
