Abstract
A layered composite product for use as a floorboard, a door, a cabinet, a wall, etc. is disclosed. The product is a layered structure that includes a rigid substrate layer having two substantially planar sides, a resin-saturated sheet layer disposed on each of the substantially flat sides, and a veneer layer disposed on at least one of the sheet layers. Also provided is a method of making the aforementioned product, the method comprising the steps of forming the layered structure, and then compressing the structure in a pressing apparatus for a time sufficient to cure the resin at under heat and pressure.
Claims23
A warpage resistant laminated composite wood product comprising a rigid substrate layer having two substantially flat sides, a melamine resin-saturated alpha cellulose sheet layer on each of said substantially flat sides, and a wood veneer layer on only one of said sheet layers.
A warpage resistant laminated composite wood product made by a method comprising the steps of:
- (a) forming a layered structure comprising a rigid substrate layer having two substantially flat sides, a resin-saturated alpha cellulose sheet layer disposed on each of said sides, and a wood veneer layer disposed on only one of said sheet layers, wherein the alpha cellulose layers are simultaneously laminated to both sides of the substrate;
- and
- (b) subjecting said structure to elevated temperature and pressure in a pressing apparatus for a time sufficient to cure said resin at said temperature and pressure, said pressing apparatus comprising a first platen and a second platen, said first platen operating at a temperature different from an operating temperature of said second platen, to provide an unwarped, laminated composite wood product.
A warpage resistant laminated composite wood product consisting essentially of a rigid substrate layer having two substantially flat sides, a melamine resin-saturated alpha cellulose sheet layer on each of said substantially flat sides, and a wood veneer layer on only one of said sheet layers.
