초록 ▼

A method of forming a reinforced composite structure comprises providing a plurality of fiberglass rovings to a resin applicator. The plastic applicator has an inlet, an outlet, and a plastic applicator cavity such that the rovings enter the plastic applicator through the inlet and exit through the outlet. The inlet and outlet are relatively positioned to spread out the rovings. Resin-containing rovings are directed between a first fiberglass matt and a second fiberglass matt and then cured. A joint that connects two frame members formed by the method of the invention is provided.

What is claimed is: 1. A method of forming a fiberglass-plastic composite structure comprising: a) providing a plurality of fiberglass rovings to a resin applicator, the resin applicator having an inlet, an outlet, and a resin applicator cavity, the rovings entering the resin applicator through the inlet along a first direction and exiting through the outlet along a second direction such that the inlet and outlet are vertically offset and the first and second directions are vertically offset to spread out the rovings, the rovings being angled along a third straight line direction extending from the inlet to the outlet, the third direction being angled with respect to the first direction and second direction wherein the rovings are embedded with a liquid resin within the resin applicator cavity to form resin-containing rovings; b) directing at least a portion of the resin-containing rovings between a first fiberglass matt and a second fiberglass matt; c) directing the resin-containing rovings, the first fiberglass matt, and the second resin-containing matt into a curing chamber; and d) curing the resin-containing rovings positioned between the first and second fiberglass matts to form the fiberglass-plastic composite structure, wherein the fiberglass-plastic composite structure emerges from the curing chamber with a predetermined linear speed. 2. The method of claim 1 wherein prior to step c) the resin-containing rovings, the first fiberglass matt, and the second fiberglass matt are directed into a forming chamber to shape the resin-containing rovings, the first fiberglass matt, and the second fiberglass matt. 3. The method of claim 2 wherein liquid resin is introduced into the forming chamber. 4. The method of claim 2 wherein the first fiberglass matt is directed into the forming chamber via a first forming collar and the second fiberglass matt is directed into the forming chamber via a second forming collar. 5. The method of claim 2 wherein the resin-containing rovings, the first fiberglass matt, and the second fiberglass matt are shaped to define a central cavity. 6. The method of claim 5 wherein the resin-containing rovings, the first fiberglass matt, and the second fiberglass matt are shaped to define one or more indentations into the central cavity. 7. The method of claim 1 wherein the linear speed is from about 1 to about 20 ft/min. 8. The method of claim 1 wherein the rovings, the first fiberglass matt and the second fiberglass matt are pulled through the resin applicator. 9. The method of claim 1 wherein the rovings, are positioned relative to the first and second matts by one or more carding plates. 10. The method of claim 1 wherein an amount of reinforcements in the reinforced composite structure is greater than about 40% by weight. 11. The method of claim 1 wherein liquid resin comprises a thermoset resin. 12. The method of claim 1 wherein the inlet and the outlet are each independently slot-shaped. 13. The method of claim 1 wherein the curing chamber comprises a curing die. 14. The method of claim 13 wherein the curing die is positionable relative to the linear direction. 15. The method of claim 14 wherein the curing die pivots about a pivot point in a horizontal and a vertical direction. 16. The method of claim 13 wherein liquid resin comprises an unsaturated polyester resin.
