Title: APPARATUS AND METHODS FOR MANUFACTURING AND REPAIRING FIBRE-REINFORCED COMPOSITE MATERIALS
Abstract:
Apparatus and device for manufacturing and repairing fibre-reinforced composite materials are disclosed. In various embodiments, the apparatus and device disclosed herein use a resin retaining/releasing device comprising resin having a viscosity that is temperature dependent for infusion into a region of a part. The resin retaining/releasing device comprises a first sheet (18) and an opposite second sheet (20) at least partially enclosing the quantity of resin. The first sheet (18) and the second sheet (20) are gas-permeable. The second sheet (20) is substantially resin-impermeable when the viscosity of the resin is above a threshold viscosity and resin-permeable when the viscosity of the resin is below the threshold viscosity.
