Abstract:
A composite sucker rod ( 12 ) has a tension rod ( 16 ) formed of a carbon fiber reinforced phenolic material and a support sleeve ( 18 ) formed of aluminum. The support sleeve ( 18 ) extends around the tension rod ( 16 ). A compressive preload is applied to the support sleeve ( 18 ) and a corresponding tensile preload is applied to the tension rod ( 16 ). The tensile preload reduces compressive loads applied to the tension rod ( 16 ). The compressive preload and the tensile preload are applied by differences in coefficients of thermal expansion of the materials from which the support sleeve ( 18 ) and the tension rod ( 16 ) are formed, and exposure to well temperatures. Opposite terminal end sections of the tension rod ( 16 ) have exterior peripheries ( 62 ) which are formed to define compound progressive radii provided having indentions ( 64 ) and protuberances ( 66 ) which fit in cooperative relation with formed surfaces of clamping members ( 34, 36 ) of end fittings ( 14 ) having profiles ( 38 ) to secure the end fittings to the tension rod ( 16 ).

Claim (Index 7):
The composite sucker rod according to  claim 6 , wherein said composite thermoset material of said tension rod is formed of a fiber reinforced phenolic material.
