摘      要：This paper proposes a new analytical solution to predict the shear modulus of a two-dimensional（2D） plain weave fabric（PWF） composite accounting for the interaction of orthogonal interlacing strands with coupled shear deformation modes including not only relative bending but also torsion,*** two orthogonal yarns in a micromechanical unit cell are idealized as curved beams with a path depicted by using sinusoidal shape *** internal forces and macroscopic deformations carried by the yarn families,together with macroscopic shear modulus of PWFs are derived by means of a strain energy approach founded on *** sets of experimental data pertinent to three kinds of 2D orthogonal PWF composites have been implemented to validate the new *** calculations from the new model are also compared with those by using two models in the earlier *** is shown that the experimental results correlate well with predictions from the new model.
