Abstract (en)
[origin: EP0978602A2] The disclosure is for laminated reinforced fiber panels constructed of materials which would not be self supporting as individual layers. The panel is constructed with the center core structure (12) being a flexible fiber mat and the two outside reinforcing layers (14,16) adding just sufficient strength to prevent the entire panel from sagging. The reinforcing layers can be scrim, metal foil, metal foil and paper laminate, or mineral board, and they can be embossed or corrugated to add strength without additional material and weight. <IMAGE>
