| Abstract: | The method of analyzing the porosity of ceramic matrix composite with high resolution computed tomography(ICT) is introduced in this paper. Firstly the ceramic matrix composite with high resolution computed tomography(ICT) is introduced in this paper. Firstly the ceramic matrix composite parts were scanned in the high resolution BT-50 ICT system imported from INDINTR Co. Ltd in Russian. The CT image was analyzed by the post-processing software and the porosity was obtained. The results were consistent with the results obtained by the ultrasonic testing method. So it is possible to evaluate the porosity of composite with the high resolution ICT system. And the ICT can be utilized for flaw detection and density analysis. |
