Abstract:

The material responses of 6 different 3-dimensional 3-D woven architectures have been evaluated in quasi-static mechanical testing. The 3-D woven architectures consist of S-glass fiber and Sc-15 epoxy matrix. The 2 mechanical experiments, tensile and laterally constrained compression tests, have been conducted on the 3-D woven specimens to evaluate their linear elastic responses and obtain mechanical properties along with observing progressive failure and ultimate failure. Two main conclusions can be made from these studies 1 the 3-D orthogonal architectures offer the smallest reduction in in-plane properties for through-the-thickness reinforcement, and 2 the 3-D layer-to-layer architectures provide the largest amount of energy absorption characterized by stable failure modes that are not typically seen in the orthogonal and laminated architectures.
