A sockliner for a shoe may be formed to include an integral fabric skirt. The fabric skirt may remain loose from the sockliner along at least a portion of the periphery of the sockliner. The loose periphery of the fabric skirt may be used to join the sockliner to other shoe components, as in a strobel-type seam.

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

A method of surface sealing a porous fibrous substrate is provided. According to the method, a porous fibrous substrate possessing a moisture content and a surface with pores is provided. A sealant composition is applied to a surface of the porous fibrous substrate and permitted to penetrate the surface pores of the porous fibrous substrate and undergo cure while participating in a foaming reaction with the moisture content to establish a water-resistant polymeric foam sealant impregnated into the porous fibrous substrate. The water-resistant polymeric foam sealant contains a polyurethane and/or polyurea.

A fibrous vehicle underbody shield and method for manufacturing the same is provided. A binderless core of non-woven fibrous material defines first and second surfaces of the fibrous vehicle underbody shield. The second surface of the fibrous vehicle underbody is opposite the first surface such that the first and second surfaces are separated by a final product thickness. The first and second surfaces include at least one molded contour that gives the first and second surfaces a non-planar shape. The non-woven fibrous material of the binderless core includes a plurality of fibers that are mechanically entangled with each other and have a coating that withstands a heat exposure of 200 degrees Celsius. The fibrous vehicle underbody shield includes a latex impregnation. The latex impregnation is disposed on at least one of the first and second surfaces and penetrates the non-woven fibrous material of the binderless core an impregnation distance.

A continuous process for preparing insulation panels having thick (0.2 mm to 1 mm) metal facing panels and a fiber-reinforced polymer foam core is disclosed. In the process, a bottom metal facing panel (2) is continuously supplied. A mat (10) of reinforcing fibers and a foamable resin composition (19) are applied to the bottom facing panel. A flexible barrier layer (5) is applied atop the foamable resin composition, and the assembly is passed through nip rolls (12,13) to compress the assembly and force the resin composition into the fiber mat. An adhesive layer (4) and top metallic facing layer (1) are then applied on top of the flexible barrier layer, and the resulting assembly is gauged and cured by passing it through a double band laminator (11).

A seat pad which can provide a favorable seating feeling while adhesion between a breathable member and a resin foam constituting the seat pad is ensured and a method of manufacturing such a seat pad are provided. A filling member including a breathable member having a ventilation function to an outside, used in a molding process of the seat pad for a vehicle integrally molded from a foam made of a foamable resin in a state where the breathable member is placed therein, and removed after the molding, is characterized by including a frame-shaped body attached to a peripheral side surface of an outside exposed surface of the breathable member and installed on a molding surface of a mold and a side-surface covering body installed upright on the frame-shaped body and partially covering a side surface of the breathable member.
摘要:
The present invention relates to a method for producing a PUR/PIR foam body, comprising the steps of providing a mold adapted for applying an underpressure to the interior of the mold; introducing a reaction mixture comprising an isocyanate-reactive component A and an isocyanate B into the mold, and applying an underpressure to the interior of the mold, so the underpressure acts on the introduced reaction mixture. The underpressure is applied to the interior of the mold no later than the reaction mixture has started to set in the mold, and the isocyanate index of the reaction mixture is ≧300.

A mold that: makes it possible to manufacture a molded foam body wherein a reinforcing member extends to a portion of the outer face of the molded body main body that corresponds to a parting line in the inner face of the cavity of the mold; and prevents molding problems stemming from the reinforcing member getting into the aforementioned parting line. Also: a method for manufacturing a molded foam body using the aforementioned mold; and a molded foam body manufactured thereby. The aforementioned mold (1) is provided with a seal member (7) that seals the space between mating faces (2a, 3a) of mold parts (2, 3) when the mold is fastened, and said seal member (7) is designed so as to be able to seal the space between the mating faces (2a, 3a) even if the reinforcing member (22) gets in between the mating faces (2a, 3a) on the cavity (4) side of the seal member (7).
