| Abstract: | A method using Computer Tomography(CT) is introduced in the paper,to measure in three dimensions the physical density and porosity of composite materials.A software compatible with PC computer was developed to rebuild images in three dimensions for analyzing and measuring.It is indicated that CT method has a good resolution for composite inner defects inspect and can provide a clear density distribution by rebuilding of images.CT is considered one of the most accurate and effective NDT for composites. |
