There is growing interest in use of composite materials in aircraft structures instead of conventional materials. EU-funded researchers examined the manufacture of composite laminates using vacuum-assisted resin infusion techniques.
Vacuum-assisted resin infusion moulding is a manufacturing process used to produce high-quality, large-scale components. In this process, preform fabrics are placed in a one-sided mould and a plastic vacuum bag is added on top. The open mould is connected with a resin source and a vacuum pump. Liquid resin infuses into the reinforced fibres thanks to the vacuum.
