3D fabrics tend to be more used as fibrous reinforcement into composite materialdue to their near-net-shape ability as well as their specific mechanical properties.Among these 3D structures, 3D warp interlock fabrics have been investigated in orderto highlight their physical and mechanical properties. Several product parameters areneeded to clearly define such a woven structure. In order to highlight the some productparameters influence, two different 3D warp interlock architectures with two differentyarn’s raw material have been produced on the same weaving loom and tested.Significant mechanical behaviors have been observed in the weft direction comparedto the warp direction, which tend to be stiffer due to less crimped yarns inside thewoven structure. Additionally, it has been found that the shrinkage values of bindingand stuffer warp yarns play an important mechanical behavior of 3D warp interlockfabrics during quasi-static tensile tests.
