摘　　要：基于MATLAB图像处理技术,本文开发了用于测定复合材料纤维密实状态的计算机图像处理程序。对金相图像进行滤波、增强和二值化处理后,根据程序求取纤维的密实指数,确定纤维的密实状态。结果表明,基于MATLAB的图象处理技术可以快速准确地测定纤维增强复合材料的纤维密实指数,为进一步研究密实状态与性能的关系提供了强有力的技术支持。A computer program to determine the fiber compaction was developed based on MATLAB image processing technology.Metallograph was filtered,enhanced and transformed digitally according to proper threshold,and a good result was achieved.The results show that the program can determine the fiber compaction index of composite laminates quickly and correctly,this technology will provide powerful supports for further research on the relations between fiber compaction and the properties of composites.
