Summary

The present study investigates the effect of bonding between the fiber and matrix on the mechanical properties of two-dimensionally woven glass-fabric composite laminates after low-velocity impacts. The progressive nature of accumulated damages within composites with strong or weak fiber/matrix bond was measured by ultrasonic flaw detector. The change of stiffness and strengths with impact were correlated with the internal material damages. The main cause of changes in mechanical properties was explained based on the matrix cracking and debonding between woven glass fiber and matrix.
