The textile reinforcements used for composites are multiscale materials. A fabric is made of woven yarns themselves composed of thousand of juxtaposed fibres. For the simulation of the draping of these textile reinforcements several families of approaches can be distinguished in function of the level of the modelling. The continuous approaches consider the fabric as a continuum with a specific behaviour. The discrete approaches use models of some components such as the yarns and sometimes the fibres. Different approaches used for the simulation of woven reinforcement forming are investigated in the present paper. Among them, an approach based on semi discrete finite elements made of woven unit cells under biaxial tension and in-plane shear is detailed. The advantage and inconvenient of the different approaches are compared.

The numerical simulation of composite forming permits to envisage the feasibility of a process without defect but also to know the directions of the reinforcements after shaping. These directions condition strongly the mechanical behaviour of the final textile composite structure. In addition, the angles between warp and weft yarns influence the permeability of the reinforcement and thus the filling of the resin in the case of a liquid moulding process. The forming of composite reinforcement can be made on a single ply or simultaneously on several plies. In this paper the different approaches for the textile reinforcement forming simulation are described. A three node element with arbitrary directions of the yarns with regard to the element sides is presented and used for the simultaneous hemispherical forming of three layers.
