he preforming step, which is the first stage of the RESIN Transfer Molding process, has been analyzed by many experimental or numerical approaches in the literature for reinforcements made of synthetic fibers. The complex mechanical behavior of a flax-based plain weave fabric was studied with the view to investigate its formability. Non-linearities in the fabric tensile behavior were observed. A preforming numerical finite element tool was used and validated by performing comparisons between experimental and numerical results. Different tensile behavior models (linear and strongly non-linear) were implemented to investigate their effect on the final shape characteristics. The tool was also used to investigate the effect of the process parameters on the computed preform shape (shear angles and draw-in) for both implemented tensile behaviors. Results show that better correlations take place when using the non-linear tensile behavior. This therefore demonstrates the importance of taking into account non-linearities in the tensile reinforcement behavior while simulating the forming of woven textile reinforcements.
