Abstract

PURPOSE:To hold liquid impregnation by forming a surface processing layer made of an amorphous inorganic ferroelectric thin film on a fibrous substrate made of inorganic fiber or heat-resisting high-molecular fiber. CONSTITUTION:A surface processing layer made of an amorphous inorganic ferroelectric conductor is formed to cover a surface of thread or fiber of a fibrous substrate made of fabric cloth and non-fabric cloth which consists of glass fiber as inorganic fiber, ceramic fiber such as potassium titanate, aromatic group polyamide fiber as heat-resisting high-molecular fiber, or the like. This obtained composite dielectric can be hence made ferroelectric without doing damage to flexibility and liquid impregnation which the fibrous substrate owns. Thread and fiber of the obtained composite dielectric contain no organic bonding materials, and so the composite dielectric is covered with an inorganic surface treatment layer with good heat-resisting performance. Consequently, not only epoxy/polyester impregnation resin but also polyimide/Si impregnation resin high in its heat-resisting temperature can be used for an impregnation thermosetting process so as to obtain an insulation layer excellent in its heat-resisting life characteristics.
