  • Structural panel
    Patent number: 4585683
    Abstract: A structural panel having a core of a phenolic foam plastics material surrounded by a woven fibre cloth impregnated with a phenolic resin. In the case of large panels, internal stiffeners may be used to improve the structural rigidity. Also the panels may have an armour layer to give the panel bullet and fire resisting properties. The armour layer may be external or internal to the panel and may be for example an alumina or a ceramic tile.
    Type: Grant
