Abstract
Orienting or placing the yarns at the third direction of three dimensional (3D) textiles may improve or degrade the in- plane mechanical properties of 3D composites. In the previous study, the bending and out- of- plane mechanical properties of 3D composites were comprehensively investigated. As the controversial results can be clarified in the literature, the study was extended to investigate the in and off- axes mechanical properties of 3D composites. The tensile and in- plane shear properties of 3D carbon woven, 3D carbon multi- axis warp knitted, and 3D carbon stitched fabrics were comparatively examined from dry structure to the composite. In addition, a carbon traditional laminated composite was produced and tested to make a comparison. According to the load bearing capacity of 3D textiles from dry structure to the composite, the 3D woven fabric shown the worst performance.
