Patent ID: 8011165

Claim:
A building material composite assembly, comprising: an essentially planar first outer substrate that is at least partly porous; a first reinforced lamination layer; an essentially planar inner substrate that is at least partly porous; a second reinforced lamination layer; and an essentially planar second outer substrate that is at least partly porous, wherein the first reinforced lamination layer joins an at least partly porous surface of the first outer substrate to an at least partly porous first surface of the inner substrate, wherein the first reinforced lamination layer includes a pressed mat or fabric containing a plurality of reinforcing fibers and a thermoset resin, the thermoset resin forming a single continuous matrix encasing the plurality of reinforcing fibers and filling pores of the at least partly porous surface of the first outer substrate and filling pores of the at least partly porous first surface of the inner substrate to form a physical anchoring or bonding of the first outer substrate and the inner substrate, the single continuous matrix being formed by the thermoset resin being included in the first reinforced lamination layer as a liquid resin such that excess liquid resin of the first reinforced lamination layer is forced into and fills pores of the at least partly porous surface of the first outer substrate and of the at least partly porous first surface of the inner substrate before the thermoset resin is cured, wherein the second reinforced lamination layer joins an at least partly porous surface of the second outer substrate to an at least partly porous second surface of the inner substrate, and wherein the second reinforced lamination layer includes a plurality of reinforcing fibers and a thermoset resin, the thermoset resin forming a single continuous matrix encasing the plurality of reinforcing fibers and filling pores of the at least partly porous surface of the second outer substrate and filling pores of the at least partly porous second surface of the inner substrate to form a physical anchoring or bonding of the second outer substrate and the inner substrate, the single continuous matrix being formed by the thermoset resin being included in the second reinforced lamination layer as a liquid resin such that excess liquid resin of the second reinforced lamination layer is forced into and fills pores of the at least partly porous surface of the second outer substrate and of the at least partly porous second surface of the inner substrate before the thermoset resin is cured.
