Abstract: Improved insulating modular panels are manufactured to incorporate into each insulating modular panel at least one vacuum insulation panel. Vacuum insulation panels are conveyed seriatim toward a pultrusion die which ultimately produces the insulating modular panels as a continuous block. Joint spacings or gaps between adjacent vacuum insulation panels and sides of the vacuum panels are filled with foam or preformed filler material to form a substantially continuous inner core which has substantially continuous side edges. Reinforcement material is applied to the inner core. The reinforcement material can be impregnated with resin prior to its application to the inner core or resin may be injected into the pultrusion die. In either event, a continuous elongated block of insulating modular panels emerges from the pultrusion die. The continuous elongated block is severed at joint spacings or gaps between adjacent vacuum insulation panels to form insulating modular panels of desired sizes from the block.

Abstract: A process for manufacture of an automotive trim piece having a polymeric skin fastened to substrate. The polymer, for example, polyvinyl chloride has the property that upon cooling to a relatively rigid state the polymer shrinks. The process includes a step of molding the polymeric skin separately from the substrate such that the skin has a rear face for abutment with an obverse face of the substrate and a pair of lips extending from ends of the rear face.

Abstract: A method of making a composite structure, such as an aircraft wing, which has a foam core and at least one outer layer of fiber reinforced resin material. A shaped foam core is prepared by compressing a rigid, closed-cell foam to the desired shape in a closed mold under heat and pressure. A sheet of flexible open-cell foam is impregnated with a thermosetting resin. A sheet of dry fiber reinforcement material is placed on one or both sides of the impregnated foam sheet. The resulting sandwich is wrapped around the foam core and the assembly is placed in a corresponding tool cavity. The tool is heated to the curing temperature of the impregnating resin. As the temperature rises, the foam core expands, exerting pressure on the impregnated foam sheet, forcing resin into the fiber reinforcement, wetting all the fibers and forcing air out of the material. As the resin cures, void-free, strong skins are formed integral with the core foam.
