  • Publication number: 20040247856
    Abstract: In order to facilitate the recycling of plastic composite materials and moldings produced thereof, the invention relates to a single-sort, mono-material composite material, comprising a core of thermoplastic foam and at least one reinforcing layer made of a composite consisting of fibers or strips of the same thermoplastic material as the foam. The invention further relates to a method for producing said single-sort composite material, during which the foam made of thermoplastic material is applied onto a pre-formed reinforcing layer and is welded there to each other and to the reinforcing layer by adding heat, a composite consisting of at least two layers of fabrics, knitted fabrics or non-wovens of fibers or strips made of the same thermoplastic material as the foam being used as reinforcing layer.
