Abstract
Drop weight impact testing was performed on hardened layer, multiaxial linear systems, or 3D systems in an epoxy matrix. Impact load vs time and impact energy vs. time response were characterized for each sample. It was found that fiber architecture plays a significant role in the impact resistance of composite structures. Three-dimensional, fully integrated structures such as 3D braids improve the impact resistance of composites. The failure mechanism and crack propagation behavior of 3D braided composite samples were studied by means of photographs, optical microscopy, and SEM. It was found that 3D braided composites experience a complex path of crack propagation, acting as a network of crack arrestors. (Author)
