This paper present two hybrids discrete continuous models for the simulation of woven fabric reinforcement preforming via explicit finite element analysis. There approaches are based 1D elements on a beam or nonlinear connectors, and 2D element account for shearing resistance of the fabric. The first developed model is built using linear and nonlinear connectors to take into account the tensile stiffness of the fabric, and a shell elastic isotropic element. The second model is based on nonlinear elements and the hypo-elastic behaviour. The determination of the material parameters is straightforward from tensile and bias extension tests. These proposed approaches have been implemented in the ABAQUS explicit finite element programs via subroutine VUMAT. There models allows the simulation of industrial part forming in a reasonable computational time. Simulations of the hemispherical shape of woven fabric 48600 C1300 have been implemented to highlight the performance of these models
