Capillary pressure contribution in fabrics as a function of fibre volume fraction for Liquid Composite Moulding processes

Liquid Composite Moulding processes are considered as promising and effective to manufacture structure composite parts reinforced with synthetic natural fabrics. The main novelty of this work is the estimation capillary pressure (Pcap) for both fabrics at different fibre volume fractions (Vf) liquids. From previous works, Pcap was defined equivalence between Washburn’s equation Darcy’s law while our novel model wicking could predict very well swelling behaviour combination definition explored in study. Linear trends, thresholds extremums conditions were found first time. These results relevant estimate importance effects during extremely valuable numerical models fibrous scale voids formation.
