    Abstract

    This paper investigates the relationship between fabric structure and composite properties for 2-D and 3-D carbon fiber reinforced composites that contain the same fiber volume fraction. The investigation involved determining the tensile strength and modulus, flexural, and interlaminar shear strengths of each specimen type. The 2-D composite shows better in-plane tensile properties than the 3-D composite due to the lower yarn crimp and consequently higher length of yarn orientated in the stress direction. Through-the-thickness reinforcement in the 3-D fabric was found to increase the apparent short beam shear and flexure strengths due to suppression of delamination.
