Post Impact

Composites are prone to delamination damage when impacted by low velocity projectiles because of the poor through-thickness strength. Therefore, some of the problems with composites are their poor impact damage resistance, weak post-impact mechanical properties, and the difficulty to inspect the impacted area by nondestructive means. Damage characterization of composite materials requires a scientific methodology, knowledge of polymeric materials, and direct field experience. In this work, low-velocity impact response of composite laminates was experimentally studied using drop-tower to determine the energy absorption. Three types of composites were used: carbon fiber, glass fiber, and mixed fiber composite laminates. In addition, these composites were characterized using thermography to quantify their post impact damage. It was found with the 3D temperature distribution that a strong correlation can be determined between the measured temperatures at the impact region with the quantification of the damage using thermal imaging with advanced mid-wave camera.

The Impact

In recent years, for the purpose of achieving enhanced mechanical properties of fiber reinforced composites, hybridized composites containing a combination of two or more types of fiber reinforcements have been explored. Perhaps the main parameter which controls the mechanical properties of the hybrid composites is the flexibility to arrange the hybrid fiber reinforcement layers in a variety of ways within the hybrid laminate. In this study, low velocity drop weight impact resistance of plain weave woven glass and carbon hybrid composites has been investigated. The study explores the effects of intra-ply arrangement sequence on the impact resistance of 24 and 32 ply laminates in which glass and the carbon plies have been differently stacked. The results show that impact resistance of woven glass fiber composites can be enhanced by hybridizing woven glass fabrics with woven carbon fabrics. The results indicate that the impact resistance is a function of the positions of the glass and carbon layers in the hybridized inter ply laminates.
