Abstract: A method for molding a plastic part comprises preforming a film laminate and insert molding a plastic substrate against the film laminate. According to one embodiment, the film laminate is preformed with re-entrant edge portions. The insert molding step involves positioning the film laminate in a mold cavity, closing the mold and injecting molten resin into the mold cavity against the film laminate. The force of the closing of the mold and the injection of the resin causes the re-entrant edge portions to curl up under the solidifying resin to ensure complete coverage of the longitudinal edges of the plastic substrate by the film laminate. According to another embodiment, a stencil of an image is made in the film laminate prior to the insert molding. The resin injected into the mold flows into the stencil so that the image is visible against the surrounding surface of the film laminate.

Abstract: The invention is directed to a layered fabric material that is breathable and has resistance to fluid penetration. The fabric has a lightweight, breathable outer layer and a layer of non-woven material. The non-woven material is breathable and fluid resistant.

The capillaries are disposed at an angle from about 5.degree. to about 60.degree. with respect to the surface of said film. The capillaries formed by the perforations allow the film layer to be breathable while resisting direct flow of liquid through the film.

Abstract: A filament wound composite structure, its tooling and method of manufacture. The isogrid filament wound composite structure is formed having at least one or more pseudo-isotropic laminate zones in its joint regions. This structure is realized through the use of specialized tooling. The ribs of the isogrid filament wound composite structure are discontinued by tapering them out into a thin skin. This is accomplished by gradually widening the grooves in the mandrel while simultaneously decreasing the depth of the grooves. This gradual change in the tooling redistributes the material in the ribs into a thin skin. The fibers that are redistributed into this thin layer, coupled with the skin wound over the top of the ribs, provide the necessary reinforcement in the joints.
