Claims
- 1. A composite structure comprising a substantially flat thermoformable sheet of a melt-fabricable perhalopolyfluoroethylene polymer resin and a knitted fabric made of glass fiber yarn and at least one monofilament of a melt-fabricable perhalopolyfluoroethylene polymer resin, said fabric being partially embedded in a surface of said sheet.
- 2. The composite structure of claim 1 wherein said melt-fabricable perhalopolyfluoroethylene polymer resin is a melt-fabricable tetrafluoroethylene copolymer resin.
- 3. The composite structure of claim 2 wherein the melt-fabricable tetrafluoroethylene copolymer resin in the sheet and in the monofilament is a tetrafluoroethylene/hexafluoropropylene copolymer.
- 4. The composite structure of claim 2 wherein the melt-fabricable tetrafluoroethylene copolymer resin in the sheet and in the monofilament is a tetrafluoroethylene/perfluoro(propyl vinyl ether) copolymer.
- 5. The composite structure of claim 2 wherein the melt-fabricable tetrafluoroethylene copolymer resin in the sheet and in the monofilament is a tetrafluoroethylene/ethylene copolymer.
- 6. The composite structure of claim 1 and castable adhesive or thermosetting resin material embedded in the exposed surface of said fabric.
- 7. The composite structure of claim 6 wherein said castable material contains reinforcement.
- 8. The composite structure of claim 1 in the form of a liner for a dished head.
- 9. The composite structure of claim 1 in the form of a cylinder.
- 10. The composite structure of claim 1 having an extensibility of at least 10 percent.
