摘要
以碳纤维/环氧树脂复合材料中的孔隙为研究对象,建立一种可以生成小尺寸不规则孔隙的随机分布算法。首先利用Matlab软件对复合材料的微观形貌图像进行处理,以获取小尺寸不规则孔隙的尺寸分布统计数据。然后以该统计数据为依据,采用改进的邻点融合法,通过C++编程建立小尺寸不规则孔隙随机分布算法。最后将孔隙微观形貌图和随机分布算法生成的孔隙分布图进行对比分析,结果表明本文算法生成的孔隙与实际孔隙的形状和分布基本相同,证明了小尺寸不规则孔隙随机分布算法的有效性和合理性。
This article takes the voids in carbon fiber/epoxy resin composite materials as the research object and establishes random distribution algorithm for generating small irregular voids of composites.Firstly,using Matlab to process the microstructure images of composites to obtain statistical data on size distribution of voids.Then,based on the statistical data,an improved neighbors′interfusion method is used to establish small irregular voids random distribution algorithm through C++.Finally,a comparative analysis was conducted between the micro morphology map of voids and the voids distribution map generated by the random distribution algorithm.The analysis results showed that the shape and distribution of the voids generated by the void random distribution algorithm in this paper are basically the same as those of the actual voids,proving the effectiveness and rationality of the random distribution algorithm for small and irregular voids in this paper.
