Abstract
Abstract Tightly integrated composite products are obtained by treating a fluorochemical member on its surface with atmospheric glow plasma in a helium gas atmosphere, and joining another member of rubber compositions, resins, metals, ceramics, or semiconductors to the surface treated fluorochemical member. By using a fluoropolymer sheet as the fluorochemical member and a metal or synthetic resin layer as the other member, there are obtained weather-resistant composite sheets in which the layer is firmly bonded to the fluoropolymer sheet.
