A composite structural panel (10) is provided, where the composite structural panel (10) includes a central honeycomb layer (16) having a plurality of box-like channels extending therethrough along a vertical direction. The honeycomb layer (16) is sandwiched between bonding layers (18) formed from a porous reinforcement material. Exterior support layers (22) are bonded or laminated to respective bonding layers (18) by adhesive layers (20). The one-piece composite structural panel is then positioned on an exterior surface of a building (12) and structurally fixed to a building stud or other building element.

1. A method of fabricating composite structural panels comprising the steps of:(a) inserting a plurality of base sheets into a first adhesive spreader, said base sheets each having a plurality of substantially parallel channels being formed therethrough and extending along a horizontal direction; (b) applying a first adhesive to upper and lower surfaces of each of said plurality of base sheets; (c) stacking said base sheets to form a base block having a plurality of honeycombed substantially box-shaped channels extending therethrough in said horizontal direction; (d) rotating said base block 90° to orient said honeycombed substantially box-shaped channels in a vertical direction; (e) cutting said base block along said horizontal direction to form a plurality of honeycomb layers; (f) sandwiching each said honeycomb layer between upper and lower bonding layers; and, (g) laminating upper and lower support layers to respective ones of said upper and lower bonding layers to form a composite structural panel. 2. The method of fabricating composite structural panels as recited in claim 1 wherein said step of sandwiching each said honeycomb layer between said upper and lower bonding layers is followed by insertion of each said honeycomb layer and said respective upper and lower bonding layers into a high-temperature roller press to bond said upper and lower bonding layers to said honeycomb layer to form a bonded honeycomb structure.3. The method of fabricating composite structural panels as recited in claim 2 wherein said step of insertion of each of said honeycomb layers into said high-temperature roller press is followed by insertion of each of said bonded honeycomb structures into an adhesive spreader.4. The method of fabricating composite structural panels as recited in claim 3 wherein said step of insertion of each of said bonded honeycomb structures into said adhesive spreader is followed by application of upper and lower adhesive layers to said bonded honeycomb structure.5. The method of fabricating composite structural panels as recited in claim 1 wherein said step of lamination of said upper and lower support layers is followed by insertion of each of said composite structural panels into a rotary press.6. The method of fabricating composite structural panels as recited in claim 5 wherein said step of insertion of each of said composite structural panels into said rotary press is followed by compression of each of said composite structural panels.7. The method of fabricating composite structural panels as recited in claim 6 wherein said step of compressing each of said composite structural panels is followed by stacking of said composite structural panels to form a stack of composite structural panels.8. The method of fabricating composite structural panels as recited in claim 7 wherein said step of stacking said composite structural panels is followed by insertion of said stack of composite structural panels into a cold press.9. The method of fabricating composite structural panels as recited in claim 8 wherein said step of insertion of said stack of composite structural panels into said cold press is followed by compression of said stack of composite structural panels.
