PURPOSE: To provide a tubular element with an FRP flange in which inner pressure resistance can be satisfactorily improved as a whole tube by further enhancing fiber reinforcing effect near a boundary between the flange and a tube body against a force which is operated at the connecting part of the tube to the flange if the using inner pressure of the FRP tube is raised by adding weeping preventing means to the inner surface of the FRP tube body and a method for manufacturing the same. CONSTITUTION: A flange is provided at the end of a tube body, and the body and the flange are made of fiber-reinforced resin by a filament winding method. A unidirectional fiber tube body reinforcing fiber structure is formed of unidirectional fiber (a), and the reinforcing fiber structure of the flange is formed by winding together the fiber (a) and random direction fiber (b) (e.g. chopped strand tape, roving cloth tape, tyrelike knitted tape, continuous tape, etc.). |
