Composite/metal joints for composite rods

A method of forming a joint between two rods, the method comprising:

• forming a groove in an outer surface of a first rod proximate a first end of the first rod, wherein the groove extends circumferentially on the outer surface relative to a central axis of the first rod, and wherein the groove extends radially inward from the outer surface relative the central axis;
• forming a cavity in a first end of a second rod;
• inserting the first end of the first rod into the cavity of the second rod, wherein the groove of the first rod is within the cavity;
• reducing a diameter of the second rod proximate the first end of the second rod to form a reduced diameter portion in the first end of the second rod by applying a radially inward force by a forming tip to an outer surface of the second rod and moving the forming tip along the central axis, wherein the reduced diameter portion is formed over the groove of the first rod and the reduced diameter portion extends radially inward into the groove of the first rod;
• applying a composite wrap circumferentially around the reduced diameter portion of the second rod, wherein the composite wrap comprises a plurality of fibers with a circumferential fiber orientation;
• and
• solidifying the composite wrap.
