| Abstract: | A model for predicting elastic property of textile structural composites is presented. Yarn undulation along both warp and weft directions is considered in the analysis. The relationship between composites elastic modulus and fabric structure parameters for 2 D and 3 D composites is created. The elastic properties of 2 D and 3 D carbon fabic/epoxy composites containing the same fibre volume fraction are examined experimentally. The experimental results coincide well with the theoretical predictions on the elastic moduli for 2 D and 3 D composites. |
