Summary

In order for ceramic fiber-reinforced polymer composites to be used in light-weight structural applications, the change of mechanical properties with loading must be addressed a priori. The extent of material damages, thus the extent of degradation in mechanical properties, for woven glass fiber reinforced polymer laminates were evaluated after a single and\or multiple low-velocity impacts. The progressive nature of accumulated damages with the load was measured by an ultrasonic flaw detector. The change of mechanical properties with impacts were correlated with damages. The main cause of changes in mechanical properties were explained based on the matrix cracking and delamination between woven glass fiber and matrix.
