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.
Claims31
A method of producing a laminated composite article, said method consisting essentially of the steps of:
- (a) forming a layered structure comprising a rigid substrate layer having two substantially flat sides, a resin-saturated sheet layer disposed on each of said sides, and a veneer layer disposed on only one of said sheet layers;
- 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.
A method of producing a composite article, comprising the steps of:
- (a) providing a rigid substrate layer having two substantially flat sides;
- (b) providing, on each of said sides of the substrate layer, a sheet layer that is substantially saturated with a thermosetting resin;
- (c) providing, on only one of said sheet layers, a veneer layer to form a lavered structure consisting essentially of said substrate layer, said sheet layers and said veneer layer;
- (d) providing the layered structure of step (c) in a pressing apparatus;
- and
- (e) subjecting the layered structure of step (d) to elevated temperature and pressure in said pressing apparatus for a period sufficient to cure said resin at said temperature and pressure.
A method of producing a laminated composite article, said method comprising the steps of:
- (a) forming a layered structure comprising a rigid substrate layer having two substantially flat sides, a resin-saturated sheet layer disposed on each of said sides, and a veneer layer disposed on at least one of said sheet layers;
- 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.
A method of producing a composite article, comprising the steps of:
- (a) providing a rigid substrate layer having two substantially flat sides;
- (b) providing, on each of said sides of the substrate layer, a sheet layer that is substantially saturated with a thermosetting resin;
- (c) providing, on at least one of said sheet layers, a veneer layer;
- (d) providing the product of step (c) in a pressing apparatus;
- and
- (e) subjecting the product of step (d) to elevated heat and pressure in said pressing apparatus for a period 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.
