Abstract
The present invention relates to a method for making a composite article by applying an adhesive composition to one side of each of two foils of metal. The adhesive composition contains an ethylene/acrylic acid copolymer and a thermoplastic styrene/diene block copolymer. A sheet of fiber-reinforced polypropylene has both of its sides coated with a second thermoplastic styrene block/diene block copolymer which includes an acid or acid anhydride component. Finally, the adhesive coated metal foils are mated with the treated polypropylene sheet under elevated temperature and pressure for forming the composite article.
