Abstract
A composite building panel that includes a fabric reinforcing sheet between one of the metal skins and the core of the panel. The fabric reinforcing sheet, which is preferably made from aramid fibers improves the impact resistance and penetration resistance of the building panel without substantially increasing weight and without adding fuel content to the panel system.

A method of manufacturing a building panel comprising:
- an outer metal skin;
- an inner metal skin;
- a polymer core;
- a fabric reinforcing sheet disposed between one of the metal skins and the polymer core;
- a first adhesive disposed between the fabric reinforcing sheet and the one of the metal skins, the first adhesive securing the fabric reinforcing sheet to the one of the metal skins;
- a second adhesive disposed between the fabric reinforcing sheet and the polymer core, the second adhesive securing the fabric reinforcing sheet to the polymer core;
- and
- a third adhesive disposed between the other of the metal skins and the polymer core, securing the other of the metal skins to the polymer core;
- the method comprising;
- applying a one side of the fabric reinforcing sheet, having the first adhesive affixed to the one side of the fabric reinforcing sheet and the second adhesive affixed to another side of the fabric reinforcing sheet, to the one of the metal skins;
- applying the third adhesive to a one side of the other of the metal skins;
- providing the polymer core;
- and
- simultaneously applying the another side of the fabric reinforcing sheet and the one side of the other of the metal skins to the polymer core.
