摘要

metal end fitting, installation of end fitting, method for installing a torque transmission / drive shaft, torque transmission / drive shaft, and method for manufacturing a metal end fitting for a particular tubular component. A metal end fitting (2) for a particular tubular member (22) made of fiber reinforced polymer matrix composite material is provided, the end fitting (2) comprising the first and second concentric surfaces extending longitudinally along a central axis (c) to form a cavity (13) for receiving one end of the tubular member (22). the cavity (13) has an outer diameter defined by the first surface and an inner diameter defined by the second surface, wherein the outer diameter and the inner diameter are chosen to provide interference fit with the respective outer and inner surfaces (26, 24 ) of the particular tubular member (22) when the member (22) is snap fit into the cavity (13). each of the first and second concentric surfaces comprises one or more longitudinal cutting teeth. when the particular tubular member (22) is snap-fitted into the cavity (13), one or more longitudinal cutting teeth are designed to cut one or more longitudinal grooves on respective outer and inner surfaces (26, 24) of the tubular member of material. composite (22) to form a mechanical locking interface. thus, the installed composite tubular member (22) is cut on both its outer and inner surfaces (26, 24) and an interference fit is generated on both its outer and inner surfaces (26, 24).
