    Abstract: A multi-layer plate is made of a core layer (A) with a honeycomb structure or foam, at least one cover layer (C) of fibre-reinforced thermoplastic material, which have been joined by an adhesive (B), compatible with the plastic of layer (C). The layer (A) is made e.g. of plastic-coated paper NOMEX (RTM), 8.8mm thick. The adhesive (B) is made of polysulphone ULTRASON (RTM) and the cover layer (C) of polyethersulphone, polyetherketone,

    Abstract: For producing moulded fibre-reinforced plastic articles, fibre material in the form of fibre strands, bundles, woven or laid fabrics is impregnated with the heat-curable plastic, transformed into a laminate in web form and, if required, cut to length in strips. A plurality of these laminate strips are compressed in a compression mould, forming the moulded article, and cured by appropriate application of heat. For the purpose of reducing the curing time and for improved quality of the moulded articles, before the laminate strips are introduced into the compression mould they are heated in a high-frequency field to a temperature about 0 to about 100 DEG C below the temperature at which crosslinking of the plastic commences.
