  Composites are prone to delamination damage when impacted by low velocity projectiles because of the poor through-thickness strength. So, some of the problems with composites are their poor impact damage resistance, low post-impact mechanical properties and the difficulties to inspect the impacted area using nondestructive means. Damage characterization of composite materials requires a logical scientific methodology and a wide knowledge of polymeric materials and additionally a direct field experience. Effort is being taken to locate the most solid Non- Destructive Testing “NDT” strategy for characterization of damage in composite materials. In this work, impact response of composite laminates was experimentally studied with drop-tower to determine the energy absorption. Three types of composites were used: carbon fiber, glass fiber and mixed fiber composite laminates. In.. Read More»
