Multi-scale analysis for material characterization of textile composites

Multi-scale analysis using the asymptotic homogenization method is becoming a matter of concem for microstructural design and analysis of advanced hemerogeneous materials. In this paper, the 3D textile composite material is simplified to minor period structure composites, and a unit cell is then built to enclose the characteristic periodic pattern in the textile composites. The predicted effective elastic moduli of textile composite materials through a combined approach of asymptotic homogenization method and the finite element method are obtained. The predicted elastic properties agreed quite well with the experimental values. Using the proposed approach, the material characterization oftextile composites can be anticipated accurately and efficiently.
