Beschreibung
Zusammenfassung:	PURPOSE:To provide a plastic pipe which can be used in various fields and exhibits excellent electric characteristics and is usable over a wide temp. region, especially extremely low temp. atmosphere by a method wherein a process for winding a fiber base material impregnated with an uncured heatcurable resin is performed under vacuum. CONSTITUTION:As an uncured heatcurable resin, e.g. an epoxy resin, an unsatd. polyester resin, etc., are used. A high strength glass fabric, a carbon fabric, an arom. polyamide fabric or a mixed woven fabric thereof as a fiber base material is impregnated with these resins. A process for winding the fiber base material impregnated with the heatcurable resin compsn. like this on a core metal is performed under vacuum, especially at most 200Torr, more preq. at most 100Torr. In addition, it is preq. that the amt. of the resin compsn. in the fiber base material impregnated with the uncured resin compsn. is in the range of 15-25wt.%.
