Abstract

A resin flow model for vacuum-bag-only prepregs is coupled with heat transfer in a commercially available finite element software. The coupled model simulates the processing of composites manufactured from glass-fibre/epoxy-powders, where the powders have been calendared onto the fabric. For these materials, resin flow occurs in the through-thickness direction, which leads to a reduction in laminate thickness (up to 40%). The resin flow model is implemented in the finite element
software using user subroutines. The results show good agreement with both experimental test data and simulations from other software. Finally, a 3D simulation is developed for processing thick-section composite parts
