摘要:
A method of forming an insulated structure for an appliance includes forming a structural enclosure having an outer wrapper and an inner liner and an insulating cavity defined therebetween, forming an insulating powder material, compacting the insulating powder material to form a pre-densified core material, disposing the pre-densified core material within an insulating cavity, wherein the insulating cavity is defined between the outer wrapper and the inner liner and expressing at least a portion of the gas contained within the insulating cavity, wherein the insulating cavity is hermetically sealed to define a vacuum insulated structure.

A 3-D (three dimensional) printing system is provided that includes a customized matrix having suitable material properties and geometric patterning to facilitate filling and retention of one or more filler material. The customized matrix defines the geometry and shape of the object. A filler mechanism that fills the customized matrix with one or more filler materials. The one or more filler materials retained within the customized matrix are cured or solidified to produce the object.

A root section of a wind turbine blade is formed by winding a length of glass fibre around a mandrel 14 to form a glass fibre layer 16 without the application of any thermosetting resin. The glass fibre layer 16 is then clamped between two pairs of elongate upper and lower clamps 18, 19. The layer 16 is then cut between the two pairs of clamps, and separated from the mandrel 14 and lowered on to a supporting hammock 26. The resulting preform 28 is then placed in a mould (not shown) where a thermosetting resin is allowed to infuse the preform 28 so as to form a segment of a root section of a desired shape. Four such segments are joined together to form the root section.

An integrated process for making an inflatable laminated article comprises extruding (11) a first film and a second film, followed by cooling (14) the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern (15, 16). The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.
摘要:
A piece of fabric (10), preferably foam-backed, is laminated to a concave, rigid substrate, such as a fiberglass shell (16) for an automobile headliner, by: a) coating the back of the fabric with a heat activable adhesive (12), e.g., a powdered polyamide; b) placing the adhesive side of the fabric against the concave side of the substrate; c) preheating a perforated male die (22) having a complementary shape to that of the substrate; d) pressing the die against the fabric; e) ejecting a shot of superheated vapor, preferably steam, through the fabric, thereby activating the adhesive; f) cooling the adhesive until it sets; and g) releasing the laminated article (26) from the die. The treatment with the superheated vapor permanently stretches the fabric in the concavities, preventing delamination after the article is released from the die.
