Interesting mechanical properties of 3D warp interlock fabrics

Abstract

The purpose of this study is to analyse the influence of weaving parameters of 3D warp interlock fabrics on their mechanical properties. Using the same yarns in the warp and weft direction, four main product and process parameters have been chosen as the weave diagram, the weft density and positions of stuffer and linking warp yarns inside the woven structure. Based on several 3D warp interlock architecture produced on the same dobby loom, the mechanical characterization of these fabrics have been performed by unidirectional tensile and bending tests, both in the warp and weft directions. Thanks to this complete protocol; a comparison between 3D warp interlock woven architectures has been done to reveal the influence of process and product parameters on their mechanical performances.
