Abstract
A low-cost method of manufacturing an all-composite composite torque tube includes winding fiber tow around a cylindrical mandrel and a plurality of eyelet forms held by an end fixture on the mandrel, whereby a flanged end coupling is formed. The method may include the use of a pre-woven composite fiber end sleeve configured to define the flanged end coupling. The wound fiber, and the end sleeve, are cured together in a single step. Metal eyelets may be installed in the bolt holes.
