Manufacturing of Primary Aircraft Structures with Vacuum Assisted Resin Infusion (VARI)

摘要

The liquid resin infusion (LRI) process has proved its high potential for enhancing production efficiency, especially in terms of reducing manufacturing cost of CFRP parts for aerospace applications. Therefore, the Institute of Structures and Design of the German Aerospace Center (DLR) in Stuttgart, Germany, developed the vacuum-assisted resin infusion process (VARI). Various test parts and 9 m long CFRP C-spars impressively demonstrated the potential of VARI for a cost-effective, reliable, robust and reproducible high-quality manufacturing process.
