ABSTRACT:
A method of manufacturing filament-wound tubes or shafts includes drywinding a plurality of elongate mandrels with the filament, inserting the filament wound mandrels into respective elongate hollow molds of a mold complex, and injecting resin such as epoxy resin under pressure into the hollow molds into intimate contact with the filament. Heat is then supplied to the mold complex to heat the resin to a predetermined temperature and for a predetermined period of time to cure the resin and thereby form the tubes or shafts. The mandrels and tubes or shafts are removed from the hollow molds and then the mandrels are removed from the tubes or shafts. Many of these activities are carried out in parallel to increase the manufacturing throughput of the tubes or shafts.
