Solid-phase composite structure and related methods

A composite structure comprising:

• a solid-phase base-substrate component;
• a fibrous component that is a plurality of polypropylene fibers embedded into and thereby mechanically attached to the solid-phase base-substrate component, wherein the fibers extend from within the base-substrate component and out of the base-substrate component through an exterior surface of the base-substrate component;
• an adhesive layer component having a first and second surface, wherein the adhesive layer component first surface is in contact with and adhesively attached to the fibrous component, and wherein the adhesive layer second surface is in contact with and adhesively attached to a first surface of an interior sheet;
• and
• a polyester reinforcing component having a first and second surface wherein the reinforcing component first surface is in contact with a second surface of the interior sheet, and wherein the reinforcing component second surface is in contact with a first surface of an exterior sheet.
