Mechanical behavior of 3D woven composites

This paper presents a comprehensive experimental study of in-plane tensile, compressive, bending, impact resistance, knife penetration and dynamic mechanical analysis (DMA) of unidirectional (UD), two dimensional (2D), three dimensional (3D) orthogonal, 3D angle-interlock and 3D warp interlock multi-layer E-glass tow based woven constructions reinforced composites. Optimization of resin %, hardener % and curing pressure has been carried out using Box and Behnken design for getting maximum possible impact resistance. The results depict that the 3D woven composites have considerably superior impact resistance, knife penetration resistance and DMA behavior as compared to UD and 2D counterparts.
