Patent number: 5089207Abstract: A single ply reinforced thermoplastic composite which may be annealed in a predetermined shape. At least one layer of plastic material is impregnated on a layer of reinforcing material to form a single flexible ply. The ply is formed to the predetermined shape, such as a roll, and annealed in that shape such that the ply returns to the shape when released after being extended therefrom. One preferred thermoplastic material is polyphenylene sulfide. The sheet is well adatped for applications such as aircraft window shades. A method of manufacturing such a composite sheet is also disclosed.Type: GrantFiled: August 29, 1988Date of Patent: February 18, 1992Assignee: Phillips Petroleum CompanyInventors: Melody A.
