X-ray radiography, X-ray radioscopy and X-ray computed tomography were performed to the C preforms and C/SiC composites made by chemical vapor infiltration method. Elementary research of the simulation of X-ray nondestructive testing of C preforms and C/SiC composites was conducted. The main contents and conclusions are summarized as follows:(1) The equivalent absorption coefficients of graphite and SiC to Al (KAl/sic, KAI/C) were measured. It was found that in 35-45KV, KAl/sic=1.1~1.2 and KAl/c=0.08~0.12. That means X-ray radiography was much less sensitive to fiber defects than to SiC matrix. It was suggested that Al Image Quality Indicator would be used to evaluate the quality of X-ray radiographs of C/SiC.

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_为1.1～1.2，Al对C的等效系数K_为0.08～0.12，所以X照相射线检测C／SiC对C纤维缺陷不敏感，而对SiC基体缺陷敏感。
