ABSTRACT:
Polyethylene terephthalate composite structures having integral crystalline skins on a foam of polyethylene terephthalate are described. The structures exhibit enhanced physical properties compared to polyethylene terephthalate foams. The structures are produced by a method that crystallizes a portion of the polyethylene terephthalate before foaming the uncrystallized portions of the structure.
