Infusion design methodology for thick-section, low-permeability preforms using inter-laminar flow media

The vacuum-assisted resin transfer molding (VARTM) process is used to fabricate large-scale composite structures that can have substantial laminate thicknesses. For thick-sections and preforms of low permeability, surface distribution media based VARTM processes such as SCRIMP require long infusion times because the resin has to flow through the complete laminate thickness limiting the process to very long gelation time resin systems. The...
