Abstract

Tubing prodn. from reinforced thermosetting resin is by guiding an impermeable flexible film over a hollow mandrel to form a tubular sleeve which is successively overlaid with helically wound and longitudinally laid filaments which have been pre-impregnated with thermosetting binder resin compsns. Lay-up occurs over a solid cantilevered mandrel which is relatively short and which supplies an internal fluid pressure which sustains the tubular shape of the lining film by inflation until the resin is sufficiently cured for the would structure to be self-supporting. Partic. for mfr. of land drainage pipes or similar required with porosity for passing liq. through the wall. Supports tubing for period necessary for curing during mfr. without requiring excessively long internal mandrels and consequent haul-off resistance.
