    Abstract

    This study investigates the forming behaviour of short flax fibre reinforced polypropylene composites in stamp forming, and develops FEA models to simulate this forming process. Pre-consolidated composites were cut into a circular shape with a diameter of 180mm, and then formed into a hemispherical dome structure to analyse two major forming modes: stretching and drawing. The application of the ARAMIS™ machine facilitates displacement and strain deformation measurements during forming. The FEA simulations developed in this study use implicit technique, and assign more than 1,900 shell elements to the deformable blank. By comparing with experimental observations, it was found that numerical simulations can accurately simulate the forming behaviour of composites prior to the initiation of failure. Element deletion function and material imperfection model are found necessary for FEA models to predict the post failure behaviour of composites.
