Experimental study of 48600 Carbons fabrics behavior using marks tracking technique method

Abstract

Lightweight and energy saving are the main challenges in the aircraft industry production, that explain the increase of composite demand and the diversity of its applications. The investigation of the shear behavior and stiffness of technical woven fabric are essential to guarantee the performance of the final product. In case of forming process (for example RTM process), the in-plane deformability of the woven fabric is necessary for forming without creating defects. The change of the fiber orientation (warp and weft) have a significant impact on final mechanical properties. In this study, the use of marks tracking technique allow the determination of the rigidity of 48600 C 1300 carbon fabrics, and allow calculation of their shear angle, lock angle during tensile and bias-extension tests.
