Abstract: A fiber reinforced panel is manufactured to include an integral vent screen. Holes are made in each of first and second sheets of fiber and the holes register with each other when the sheets are stacked within a mold. A screen material is placed between the first and second sheets so that a part of the screen material that registers with the holes in the first sheet and second sheet is exposed. Filler inserts are inserted into the holes of the first and second sheets to mask the screen. A resin is provided and cured to bond together the first and second sheets and the screen. Thus, the screen remains exposed after the first and second sheets and screen have been bonded together by the resin, thereby forming a fiber reinforced panel having an integrally molded vent screen therein.

Abstract: A rotocast composite hybrid method for efficiently making strong but lightweight parts. The method includes filling a mold with a volume of resin through an access port and then sealing the access port by positioning a lid over the access port. The method includes mounting the mold in a rotocasting machine and then operating the rotocasting machine to rotate the mold about two orthogonal axes until a layer of the resin is applied uniformly over an inner surface of the mold to form an outer wall of a part. The method includes removing the lid and then applying a reinforcement material (e.g., sheets of woven fiberglass) to an inner surface of the outer wall of the part through the access port. The applying of the reinforcement material also involves wet layup such as by binding the reinforcement material to the inner surface by applying additional resin to the reinforcement material.
