| Abstract: | Different dimensional specimens of 3D carbon/carbon composites were made.The microstructure of the 3D carbon/carbon composites was investigated with micro-CT.The correction of projective images rotational center,denoising,and ring artifacts correction were performed.Results show that the micro-CT images of 3D carbon/carbon composites are improved through data processing.And the microstructures are accurately displayed. |
