ABSTRACT:
Tightly integrated composite products are obtained by treating a fluoropolymer member on its surface with atmospheric pressure glow discharge plasma in a helium gas atmosphere containing 97% by volume or more of helium gas, and joining another member of rubber compositions, resins, metals, ceramics, or semiconductors to the surface treated fluoropolymer member. By using a fluoropolymer sheet as the fluoropolymer 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.
