PROCESS AND DEVICE FOR THE CONTINUOUS MANUFACTURE OF FIBRE-REINFORCED HOLLOW ELEMENTS OF SYNTHETIC MATERIAL, AND HOLLOW ELEMENT OBTAINED

摘要

1. A process for the continuous production of fibre-reinforced plastics hollow sections, wherein a parting foil (3), and inner gel coat and a first layer of fibrous material (20, 21) are applied round a stationary mandrel (1), then further layers (34, 37) of fibrous material and liquid plastics material are laid round the first layer of fibrous material (20, 21), the hollow section is calibrated in a forming tool (40) and then heated so that the plastics material is cured, and wherein the cured hollow section is continously withdrawn from the mandrel (1) by a gripping device (52) and is finally cut into lengths, characterized in that the inner gel coat is applied to the parting foil (3) provided on the mandrel (1) and is gelled by heating, that the first layer of fibrous material (20, 21) with the liquid plastics material is laid, overlapping, on the inner gel coat, and that before the further layers (34, 37) of fibrous material are applied, the hollow section is heated and the plastics material in the first layer of fibrous material (20, 21) is cured.
