Abstract

Experimental characterization of the textile composite materials was conducted to determine the effect of fiber architecture and preform process parameters on the elastic properties and strength of 3-D woven and braided composites. Nine different architectures comprised of layer-to-layer, through-the-thickness woven preforms, and tri-axial four-step braided prefrom composites were tested. Tensile, compression, and shear tests were carried out to determine the in-plane properties. The preform architectures tested include variations in tow size (fiber count within a tow) and pitch for the woven composites, and braid angle and tow size for the braided composites. The experimental results were utilized to verify and validate analytical stiffness and strength models developed considering the preform-process to material property prediction schemes. The details of the analytical models are presented elsewhere, the model comparisons are presented in this paper.
