Method and system of vacuum assisted resin transfer moldings for repair of composite materials and structure

A vacuum-assisted resin transfer molding repair system for a damaged composite panel, comprising:

• a repair patch assembly including a plurality of layers, the assembly including an adhesive layer for coupling to the panel and a first vacuum bag having an inlet;
• a scrim material configured to be disposed between the repair patch assembly and panel;
• a cartridge adapted to contain resin;
• a pump having a port, the port being coupled to the inlet;
• an inlet valve and outlet valve;
• a first tube coupled between the cartridge and an inlet side of the repair patch assembly, the first tube including the inlet valve configured to control an amount of resin dispersed into the repair patch assembly;
• a second tube coupled to an outlet side of the repair patch assembly, the second tube including the outlet valve;
• and
• a third tube coupled between the pump and port for delivering a pressure response to the repair patch assembly.

A system for a vacuum-assisted resin transfer molding repair, comprising:

• one or more repair patch assemblies;
• a piece of scrim material;
• at least one resin cartridge;
• a surface preparation tool;
• and
• a repair equipment tool.
