This paper presents an analytical and numerical model for the prediction of tensile elastic constants of a novel textile structural composite, namely co-woven-knitted fabric (CWKF) composite. Based on the CWKF geometry model previously developed, the direction angles of basic-cells of the weft, warp, and stitch yarn components in a representative volume elementary were determined. The micromechanics method and both isostrain and isostress conditions were applied to the yarn and the pure resin components, and the overall stiffness or compliance matrix of the composite was obtained. The normal elastic constants were calculated and compared with the experimental ones. The results showed that the relative errors between the calculated and the tested values are at an acceptable level (<10%). Thus, the proposed model can be used for the predictions of other elastic constants of the CWKF reinforced composite and effects of structural parameters.
