Abstract: A poylamide 6 - glass fiber composite was evaluated using synchrotron radiation laminography to study the distribution of fiber orientation and changes in the volumetric strain within the composites before and after plastic deformation. A cylinder correlation fiber analysis followed by a tracing algorithm was utilized to identify individual fiber and measure the distribution of fiber orientation. In addition, two CT images were captured from the samples before and after plastic deformation to measure the level of volumetric strain within different regions of the image. The results indicated that rice-like voids within the composites have been deformed extensively and are probably the starting points for crack propagation within the composites.
