PRODUCTION OF TUBULAR MEMBER MADE OF FIBER REINFORCED RESIN

摘要

PURPOSE:To produce a tubular member made of a fiber reinforced resin free from strain and excellent in mechanical strength in a sufficient low cost by the addition of sufficiently simple equipment by uniformly performing thermal curing from both inner and outer pheripheries at the time of production by a filament winding method. CONSTITUTION:A curable resin impregnated fiber material (m) is wound around a hollow mandrel 31 and the fiber material wound mandrel M is received in a curing oven 53 having a blower 52 fitted with a heater provided therein and the emitting orifice 54 of the blower 52 is allowed to communicate with one end of the hollow mandrel 31 and a wound fiber material is heated from the outer periphery thereof by the heating atomosphere in the curing oven 53 and also heated from the inner periphery thereof while the heating atmosphere in the curing oven is further heated by the blower 52 to be sent into the hollow mandrel 31 to be cured.
