Abstract:
The present invention relates to a method of manufacturing a thermoplastic product in a mould comprising at least two opposing mould parts defining a cavity to at least one of press mould and injection mould the product from thermoplastic material. The method comprises providing a fiber reinforced sheet of a fiber fabric encapsulated in a thermoplastic resin, forming the fiber reinforced sheet in correspondence with a shape of the product and arranging the formed fiber reinforced sheet on and connected close fittingly to an outer surface of the product. The method further entails dividing the fiber reinforced sheet in portions in shape optimized for low cut losses, said shapes being from the group at least comprising rectangles, squares and honeycomb or six-cornered shapes, and welding two or more fiber reinforced sheets or portions thereof together, prior to forming the combined fiber reinforced sheet in correspondence with a shape of the product. Further more the invention relates to a product, comprising a layer of thermoplastic material and a reinforcement, wherein the reinforcement comprises at least one fiber reinforced sheet and is arranged on and connected close fittingly to an outer surface of the layer.
Abstract:
The present invention relates to a method for manufacturing a form element, comprising of: I) arranging a cladding layer (5) of polar plastic material in a mould (1); ii) bringing at least a part of the cladding layer into contact at increased pressure with thermoplastic plastic material (7) of increased temperature; iii) allowing the thermoplastic plastic material and the polar cladding layer to cool, wherein the thermoplastic plastic material forms a solid plastic element which is adhered to at least a part of the polar cladding layer. The invention further relates to such form elements and to the use thereof in vehicles.
Abstract:
The present invention relates to a method for manufacturing a covering element (2), comprising of : i) arranging in an injection mould (1) a sound- absorbing element (6) and an adhesive layer (5), such that the adhesive layer extends over at least a part of the inner surface of the sound-absorbing element; ii) introducing thermoplastic plastic material of increased temperature into the mould at increased pressure, wherein the plastic material spreads over substantially the outer surface of the sound-absorbing element and over a part of the adhesive layer; iii) cooling the whole such that the thermoplastic plastic material forms a solid carrier element which is adhered to a part of the adhesive layer and wherein the sound-absorbing element is at least partly enclosed between the carrier element (8) and the adhesive layer, to the covering element and to the use thereof. The present invention further relates to a covering element, whereby the thermoplastic plastic material is not fibre-reinforced.
