Abstract

PURPOSE: To prolong a length of usable time of the prepreg tape, also with a work of winding facilitated, by fabricating a prepreg micatape using a method in which a resin, being composed of epoxy resin and acid anhydride with hardening accelerator not included, is impregnated to the base material of mica.
CONSTITUTION: Epoxy resin and acid anhydride with hardening accelerator not included, for instance, varnish, with methyl CD acid anhydride made containing, is applied to a mica tape by processing a back lining with glass cloth or glass fiber, being heated and dried, with an insulating prepreg mica tape constructed. In such way, a process of tape winding can be facilitated simultaneously with a length of usable time of the prepreg tepe prolonged. And in case of rolling the prepreg tape on a conductor to process an insulation, a hardening operation of the varnish after volatilizing solvent-water with a heating and drying processed under a reduced pressure after the work of winding can provide an insulating layer with a volatile component and air gap not made residual.
