Title of Invention

A SEMI-AUTOMATIC EQUIPMENT FOR MANUFACTURING LONG COMPOSITE TUBES

Abstract The present invention relates to semi-automated equipment for manufacturing long composite tubes/pipes wherein a number of pre-impregnated fibre tapes are laid longitudinally on a mandrel throughout the diameter and are partially overlapped on each other to effectively cover the entire expanse of the circumference. A helical winding of another preimpregnated fibre tape simultaneously follows it on it, in the same pass. Such layers of longitudinal and circumferential tape are laid and wound one on top of the other till the required thickness of the tube/pipe is built up. Arrangement and devices to control the laying and winding process parameters like tape tension, tackiness, overlap, compaction, fibre direction etc. are all incorporated within the carriage of the equipment. The same facility is flexible enough to be used for conventional method of helical winding of individual fibre filaments, if desired.
