A method of resin transfer molding uses an open base mold filled with fiberglass material and a soft tool sealed over the base mold. A vacuum is applied to a vacuum chamber that surrounds the mold and communicates with the fiberglass material through vacuum conduits. Resin is injected into the closed mold and is drawn through the fiberglass material to the edge of the mold with the assistance of the vacuum. The soft tool is preferably a flexible sheet having an edge seal to connect to the base mold and a vacuum channel with a vacuum port that surrounds the mold. The injection head releasably connects to the soft tool and preferably uses a solenoid actuated injector to supply resin to the mold. The injection head can include a self sealing device to seal the injection port and a self cleaning mechanism for flushing resin from the interior chamber of the head.

Method of resin transfer molding and components for use therewith

A multilayered submersible structure has an outer coating that is disposed in contact with water in which the structure is submerged, a current distribution layer or charge distribution layer, an electrical conductor connectable in electrical communication to a source of electrical power, and a support structure. By selectively energizing the current distribution layer, or charge distribution layer, chemical and ionic changes can be caused in the water immediately adjacent the outer coating or layer to inhibit the growth of marine organisms on the outer surface of the submersible structure.
