Abstract

PURPOSE: A plurality of pressing equipment are set around the outer peripheral surface of the core mold and the forming materials is fed in turn between the core mold and the pressing equipment and formed in spiral, thus controlling the wall thickness and producing thick-wall composite pipes with air-tight surface.
CONSTITUTION: First, releasing material 5 and glass roving impregnated with a resin 6 are wound in turn around the outer surface of the core mold 1 that is rotating in the peripheral direction and moving in the direction along the axis to form the inner surface layer. Forming material 7 consisting of resin concrete containing a reinforcing matrial as glass short-cut fibers is fed between the inner surface layer and pressing roll 2 to form the forming material layer with the prescribed thickness around the core mold 1 in spiral. Then, another forming material 10 consisting of resin concrete and others is fed to form the intermediated layer with the prescribed thickness. Finally, glass roving 12 impregnated with a resin is wound thereupon to form the top layer and cured by passing them through furnace 13.
