X-ray radiography, X-ray radioscopy and X-ray computed tomography (X-ray CT) were performed to the C preforms and C/SiC composites made by chemical vapor infiltration(CVI) method.
本文选择X射线照相、X射线实时成像和X射线CT等三种方法对C纤维预制体及C/SiC复合材料进行了检测和研究,并对C/SiC复合材料X射线检测的计算机模拟做了初步的探索,主要研究内容和结果如下: (1) 测定了C(高纯石墨)和SiC的X射线照相等效系数,在35~45KV的条件下,Al对SiC的等效系数K_(Al/SiC)为1。
