Fiberglass epoxy laminates are strong in out-of-plane loading such as low velocity impact. Woven textile composites have better properties in mutually orthogonal and out of plane directions than the unidirectional laminates. Along with the improvement in properties, they have low manufacturing cost since much of the fabrication can be automated. In the present study, different weave architectures such as basket weave, twill weave, 4 harness satin and 8 harness satin were studied numerically for response under low velocity impact loading. Main consideration was given to the maximum load carrying capacity and maximum energy absorbed by the laminates. All numerical investigations were performed using LS-DYNA® software. The laminates were modeled in VPG using 3D solid elements in a mosaic fashion to represent different weave patterns. Mechanical properties were calculated by classical micro-mechanical theory and assigned to the elements.
