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 translation: 本发明涉及一种在模具中制造热塑性产品的方法，该方法包括至少两个相对的模具部件，所述至少两个相对的模具部件限定了至少一个压模和从热塑性材料注射成型的模腔。 该方法包括提供一种包封在热塑性树脂中的纤维织物的纤维增强片材，根据产品的形状形成纤维增强片材，并将成形的纤维增强片材布置在产品的外表面上并且紧密地连接到产品的外表面上 。 该方法进一步包括将纤维增强片材划分成针对低切损失优化的形状，所述形状至少包括矩形，正方形和蜂窝状或六角形状，并且焊接两个或更多个纤维增强片或其部分 在形成与产品的形状相对应的组合纤维增强片材之前。 此外，本发明涉及一种包括热塑性材料层和增强材料的产品，其中所述增强材料包括至少一个纤维增强片材并且被布置在该层的外表面上并且紧密地连接到该层的外表面上。
