Resin infusion system for manufacturing reinforced plastic parts using fiber preforms comprises gas impermeable thermoplastic elastomer membrane forming a closed chamber around fiber preform

A fiber preform(2) in a tool(3) is covered by a gas impermeable film of thermoplastic elastomer which forms a membrane(4). The membrane creates a closed chamber(7) either by itself or with the tool inner surface(6). Resin is introduced into the chamber and penetrates the fiber preform. The membrane(4) is drawn onto the inner surface(6) and any materials(10,16) to be attached to the rear side of the finished part by vacuum or pressure-assisted vacuum. Membrane thickness is 0.5-3mm. Liquid resin is supplied through the membrane into the closed chamber(7) by a feed line. The outlet(9A) of the material feed line is omega shaped. A bulge(4A) in the membrane holds the feed line outlet. Resin flow distribution between the fiber preform(2) and the outlet of the feed line is aided by a woven fabric(17). A connection(8) to a suction system passes through the membrane unit and enables resin to be drawn into the closed chamber from a storage vessel.

Vacuum resin impregnation process

A process and system for vacuum impregnation of a fiber reinforcement, such as carbon cloth, with a resin to produce a resin-fiber composite. Liquid resin enters in arrangement or system comprising a fiber reinforcement layer on a tool or mold and is directed via a system of flow paths to impregnate the fiber reinforcement layer uniformly across the width thereof and along the length of the fiber reinforcement layer. According to one embodiment, a fiber reinforcement layer, e.g., carbon cloth, is placed on a tool. A porous paring film is applied over the fiber reinforcement layer and a bleeder layer, e.g., fiberglass, is applied over the parting film. A non-pourous film is placed over the bleeder layer, a breather cloth, e.g., fiberglass, is then applied over the non-porous film, and a vacuum bag is placed over the entire assembly and sealed to the mold surface. Liquid resin is fed to the assembly within the vacuum bag. Resin spreader means, e.g., a transverse strip of fiberglass cloth, or mechanical means, such as a slotted tube, receives the liquid resin and distributes it initially across the panel adjacent one end of the reinforcement layer after the vacuum has been applied to the assembly. The liquid resin is drawn through the bleeder cloth and through the fiber reinforcement layer from one end to the opposite thereof to completely impregnate same. The resin system is designed so that it will commence to gel when the liquid resin has completely impregnated the fiber reinforcement layer.

Method and apparatus for shaping, forming, consolidating and co-consolidating thermoplastic or thermosetting composite products

A method of shaping, forming, consolidating and co-consolidating a workpiece of layers of thermoplastic or thermosetting composite material into a final composite product. The associated apparatus includes upper and lower sheets of Kapton, Upilex or equivalent film which are positioned between upper and lower supports, respectively, in facing relationship and adapted to receive therebetween a workpiece to be shaped and formed. Means are provided for applying high heat to opposite sides of the supports, the sheets and the workpiece. Means are also provided for applying high pressure to the upper sheet, a diaphragm, and one side of the workpiece and for applying vacuum pressure to the other sheet and the other side of the workpiece for shaping and forming the workpiece into the final composite product.

Roll-consolidation of thermoplastic composite laminates

An apparatus for consolidating sheets (13) of continuous graphite fiber in a thermoplastic matrix resin uses a roller (10) in conjunction with a heating surface (16) and a vacuum bag (11). A tack-welded stack of composite sheets (13) or prepreg is assembled onto a frame support structure (27) and placed into the vacuum bag (12) as an assembly (28) which is placed on a heated surface (16) whereby its temperature is elevated above the melting point of the matrix resin in the composite sheets (13). The roller (10) rolls over the bag (11) with the sheets (13) therein whereby any remaining air and gas between the sheets (13) is forced out ahead of the roller (10). After the roller (10) has passed atmospheric pressure on the vacuum bag (12) is sufficient to prevent spontaneous delamination of the hot laminated panel formed by the sheets (13). The assembly (28) may then be moved to a cooling table (26) to complete the laminate consolidation process.
