Multilayer Interlocked Woven Fabrics: Simulation of RTM Mold

Based on the type of interlacements, the multilayer fabrics are catagorised into angle interlocked and layer interlocked structures. In angle-interlock structures, warp yarns of each layer interlace with the weft yarns of the adjacent layers, while in layer-interlock structures, warp yarns interlace the top and bottom layers of the fabric.
