Abstract

The effect of gap ratio on elastic properties of triaxial weave fabric (TWF) composites was numerically investigated by FEA method. Firstly, based on geometry construction and basic parameters of TWF composites, the relationship was determined between both surface density and feature length of representative unit cell and gap ratio. Secondly, the FEA model of TWF composites was established for predicting tension, compression and tear stiffnesses. The predicted results correlate well with experiments of the literature. Finally, the effect of the gap ratio on elastic properties of TWF composites was analyzed. It is found that the tension, compression and tear stiffnesses significantly decrease with the increasing of gap ratio, while the specific stiffness and Poisson's ratio change insignificantly.
