| 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. |
