  • Rigid shaped body comprising a plurality of superposed and/or adjacently laminated and commonly pressed oriented thermoplastic carriers and a method for producing the same
    Patent number: 4748072
    Abstract: With a rigid shaped body of a plurality of oriented, i.e., stretched thermoplastic carriers in film, ribbon, monofil or fiber form, the plastic carriers are superposed and/or adjacently laminated and commonly pressed. In order to prevent a decrease in the favorable properties obtained by stretching of an individual plastic carrier during pressing, the stretched plastic carriers are coated with thermoplastic material on the sides getting into contact when superposed and/or adjacently laminated. The coating material has a crystallite melting temperature or a glass temperature lower than the plastic carriers. The thickness of two adjacent coating materials each is smaller than the thickness of a plastic carrier.
