摘要: 提出了一种基于显微CT技术的碳纤维复合材料体孔隙率测量的新方法,分析了采用显微CT技术测量孔隙率的实验原理,对实验结果进行了图像处理,并统计体孔隙率。实验结果表明,显微CT技术是一种行之有效的碳纤维复合材料体孔隙率测量技术,通过图像灰度进行阈值分割可以清晰地分辨材料内部基体与孔隙,且测量过程中应选择足够大的试样体积,测量值才能真实反映材料内部的体孔隙率。

Abstract: A new method was proposed for volume porosity measurement based on micro-CT technology. The principle of micro-CT technology was analyzed, picture processing of results was done, and volume porosity was quantitated. The results show that micro-CT technology can be effectivly used on CFRP volume porosity measurement, and matrix and voids distinguish. In order to obtain accurate porosity result, large volume of representative specimen is necessary.

Key words: micro-CT technology, CFRP, volume porosity
