Interesting Properties of 3D Warp Interlock Fabrics as Fibrous Reinforcement for Composite Material

AXEL KECECI, FRANCOIS BOUSSU, DAMIEN SOULAT

Abstract


3D fabrics tend to be more used as fibrous reinforcement into composite material due 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 order to highlight their physical and mechanical properties. Several product parameters are needed to clearly define such a woven structure. In order to highlight the some product parameters influence, two different 3D warp interlock architectures with two different yarn’s raw material have been produced on the same weaving loom and tested. Significant mechanical behaviors have been observed in the weft direction compared to the warp direction, which tend to be stiffer due to less crimped yarns inside the woven structure. Additionally, it has been found that the shrinkage values of binding and stuffer warp yarns play an important mechanical behavior of 3D warp interlock fabrics during quasi-static tensile tests.
