Abstract: Improved heavy duty sandwich elements having A. A SURFACE LAYER B. A LAYER OF ADHESIVE APPLIED TO THE SURFACE LAYER AND IN WHICH FLOCK FIBERS OF VARYING LENGTHS ARE EMBEDDED, AND C. A FOAM CORE ADJACENT THE ADHESIVE LAYER, INTO WHICH FOAM CORE THE FLOCK FIBERS EXTEND, WITH THE LAYER OF ADHESIVE AND FIBERS; AND WHICH FORMS A MARGINAL ZONE WHEREIN THE FOAM CORE HAS A DENSITY THAT DECREASES CONTINUOUSLY FROM THE MARGINAL ZONE TO THE INTERIOR OF THE FOAM CORE.
