The wall element (10) comprises a molded part (12) made of fiber-reinforced plastic material and having an outer surface (14), where a plastic film (18) is disposed on the outer surface with high tensile strength in an area-wise manner. The plastic film has tensile strength of 20 N/mm 2>or more, and a breaking elongation of 250% or more. A layer of the plastic film is formed on the basis of polyvinyl acetate and/or polyurethane, polyvinyl butyral (50-80 wt.%) and polyethylene. The plastic film is a single-layer film or a multi-layer film, and comprises several layers.

The plastic film has tensile strength of 20 N/mm 2>or more, and a breaking elongation of 250% or more. A layer of the plastic film is formed on the basis of polyvinyl acetate and/or polyurethane, polyvinyl butyral (50-80 wt.%) and polyethylene. The plastic film is a single-layer film or a multi-layer film, and comprises several layers, where a layer formed on the basis of polyvinyl acetate and/or polyurethane is arranged between the two further layers, which are formed on the basis of polycarbonate and/or polyethylene terephthalate. The plastic film has a thickness of 300-500 mu m, is fixed on the outer surface of the molded part by self-adhesion and/or adhesive agent, and is formed in an UV-absorbing-, a flame retardant- and an electrically conducting manner. The layer of the plastic film comprises metallic nanoparticles. The plastic material of the molded part comprises duroplastic material. The plastic material of the molded part comprises thermoplastic high-capacity plastic material. The plastic material of the molded part is reinforced with glass fibers, carbon fibers and/or aramide fibers. The fibers in the plastic material have a length of more than 50 mm and are present as uni-, bi- or multi-directional fabric or knitted fabric. The wall element forms a part of the land-, aircraft- and space vehicle. |
