Abstract

A fluorocarbon resin composite includes a fluorocarbon resin layer on a base, in which a fluorocarbon resin constituting the fluorocarbon resin layer is crosslinked by electron beam irradiation, and the base has a desired shape obtained by machining. The fluorocarbon resin is composed of a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, polytetrafluoroethylene, or a mixture of the tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer and polytetrafluoroethylene. A fluorocarbon resin composite, cookware, and a roller and a belt for use in office automation equipment are each produced by applying an uncrosslinked fluorocarbon resin on a base, subjecting the fluorocarbon resin to electron beam irradiation in a low-oxygen atmosphere to crosslink the fluorocarbon resin while the temperature of the fluorocarbon resin is maintained at a temperature equal to or higher than the melting point of the fluorocarbon resin, and machining the base into a desired shape. There is also provided methods for producing them.
