GLASS CLOTH FOR REINFORCING FLUOROPLASTIC AND COMPOSITE BODY REINFORCED BY SAID GLASS CLOTH

摘要

PURPOSE:To provide glass cloth for reinforcing fluoroplastics having adhesive properties to fluoroplastics and a composite body composed of the glass cloth and fluoroplastics. CONSTITUTION:Heat cleaning glass cloth is dipped in a treating liquid containing a silane coupling agent having at last one amino group in structure such as N-beta-(N-vinylbenzylaminoethyl)-gamma-aminopropyl trimethoxysilane, and dried and thermally treated, thus obtaining surface-treated glass cloth. Said surface-treated glass cloth is held between fluoroplastic films such as tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer films to acquire a laminate, and the laminate is heated, pressed and molded, thus obtaining a composite body.
