The three- dimensional (3D) textile reinforced composites have extraordinary mechanical properties in their third direction thanks to the separated yarn or fiber group, which is placed at the thickness direction. Therefore, the 3D composites have been demanded by various industries for decades such as aviation, space, defense, automotive, etc. The 3D textiles can be obtained by the weaving, knitting, sewing, tufting, braiding or non- woven production methods. The different production methods gain specific structural and mechanical properties to the 3D composites. Although number of research studies were carried out to mechanically characterize the 3D composites, the mechanical properties of 3D composites were comparatively examined according to the production methods in the few studies.
In this study, the 3D carbon woven, 3D multi- axis carbon knitted, and 3D stitched carbon woven composites were produced, and their tensile properties were investigated. As regards the tensile strength and stiffness values, the significant differences were determined among the 3D composites.
