ABSTRACT:
The present invention is a composite laminated sheet material suitable for structures such as containment sumps. The laminated material comprises a fabric-backed thermoplastic layer upon which thermoset plastic is applied to the fabric side. The thermoplastic layer is formed by contacting a layer of fabric onto a layer of molten thermoplastic such that the liquid thermoplastic permeates a portion of the fabric layer to form a mechanical bond with the fabric layer when the thermoplastic layer cools and hardens. Thermoset plastic, such as fibreglass resin, is sprayed onto the fabric side of the thermoplastic layer to allow the liquid resin to permeate the fabric layer. Once the resin cures and hardens, the fabric layer is mechanically bonded to the cured thermoset plastic layer to effectively bond the thermoplastic layer to the thermoset plastic layer.
