• Abstract:
  Presentation overview: establish the fundamental understanding of the various VARTM processes; Flow model is fully developed for SCRIMP, VAP, and CAPRI process; Compaction behavior has been evaluated for all processes; Dry compaction during debulking; Relationship between compaction, permeability and pressure changes has been established; Effect of resin bleeding; Model has been implemented; Effect of dual-scale flow behavior has to be further studied to better understand micro-void formation; Optimize membrane material (VAP); Understand membrane mechanisms; Recommend material improvements (increased pressure, improved drapability); Establish an elevated temperature VARTM work cell for toughened epoxies; Develop a material database for aerospace resins
