Abstract:
1. A multi-layered, structural, corrosion resistant composite comprising: a core layer having a first surface and an opposing second surface, said core layer comprising a closed cell polymeric foam, said core layer also having a plurality of intersecting slits penetrating said first surface that extend to a depth that is greater than one-half of the thickness of said core layer; a first fiber reinforced layer being bonded to said first surface of said core layer, said first fiber reinforced layer including a first woven mat of reinforcing fibers and a first non-woven mat of reinforcing fibers, said first woven mat and said first non-woven mat being coated with a first polymeric resin, and said first polymeric resin filling said intersecting slits in said core layer; a second fiber reinforced layer being bonded to said second surface of said core layer, said second fiber reinforced layer including a second woven mat of reinforcing fibers and a second non-woven mat of reinforcing fibers, said second woven mat and said second non-woven mat being coated with a second polymeric resin; and a corrosion resistant thermoplastic liner layer being bonded to said second fiber reinforced layer remote from said core layer.
