Claims8
A reinforced polymeric composite, comprising:
- a foam core of a first polymeric composition;
- a skin surrounding said core of a second polymeric composition;
- a three dimensional interface chemically and mechanically bonding said core to said skin comprising strands of a high modulus material including continuous longitudinal strands substantially uniformly peripherally spaced about the outer surface of said core and the inner surface of said skin, a transverse layer of first chopped strands randomly contacting said longitudinal strands and second chopped strands inclined with respect to said transverse layer and having end portions thereof embedded in both said skin and said core.
