Braiding is an automated preforming method that is well suited to produce closed profiles. Integral hollow profiles allow weight reduction compared to differential assembled shell structures. Automotive body in white is a typical application. In contrast to Non Crimp Fabrics (NCF) braided fabrics show significant reduction in mechanical properties. As main driver the undulation of the fibers is identified. In order to investigate this influence, braided fabrics with different weave styles and roving sizes are provided. Therefore, diamond, twill 2/2 and twill 4/4 braided fabrics are compared. Two roving sizes are evaluated: Tenax HTS40 12k and SGL C30 50k. Due to different amount of filaments, the width height rate alters and thus the resultant undulation. The mechanical tests are performed according to following standards: tensile DIN EN ISO 527-4, compression ASTM D6641-01 and ILSS DIN EN ISO 14130. The tests are performed in two directions, direction 1, corresponding ±45° fiber angle in the specimen, and direction 2, 0/90° fiber angle in the specimen. To fabricate the specimens, textiles with altered braid set ups of both fiber types are produced on tubular core, unwound after longitudinal cut, stacked and cured with epoxy resin system Hexcel RTM 6. Tensile and compression test results in direction 1 show for all weaves similar trends and there is no influence due to the fiber architecture. In direction 2 the twill 4x4 has 18% higher tensile strength compared to the diamond braid. Under compression load the difference is more significant. The compression strength of twill 4x4 is 30% higher than the strength of the diamond braid. For the interlaminar properties the undulation has a contrary effect. The diamond braid has the highest shear strength. The smaller roving size shows a positive effect to the strength under compression and tensile load. The 12k twill 4x4 weave has 39% higher tensile strength and 11% higher compression strength than the 50k twill 4x4.
