RESEARCH ON DIGITAL RADIOGRAPHIC DETECTION TECHNOLOGY OF POROUS C/SiC COMPOSITES

Abstract

Abstract: The two digital imaging techniques of CR and DR were studied for porous C/SiC composite plate components. The reference block for evaluating the digital photographic quality of porous composites was designed, and the influence of the parameters such as tube voltage and exposure amount on the test results was studied. The results show that the parameters such as tube voltage and exposure amount can affect the detection effect of CR and DR, and the groove and hole-type reference block can be used to characterize the quality of X-ray digital detection image, which provides a basis for optimizing the parameters of X-ray inspection of composite components.

Key words: composite material, DR, CR
