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 10):
The composite sucker rod according to  claim 9 , wherein said support sleeve is a continuous tubular sleeve which extends around said tension rod, from said first fitting to said second fitting; and\n wherein downhole well temperatures define operating temperatures which exceed surface ambient atmospheric temperatures, and said support sleeve and said tension rod are formed of a tubular sleeve material and fiber reinforced composite plastic material, respectively, which having respective coefficients of thermal expansion such that at the surface ambient atmospheric temperatures said compressive preload and said corresponding tensile preload are not applied to respective ones of said support sleeve and said tension rod, and at the operating temperatures said compressive preload and said corresponding tensile preload are applied to said support sleeve and said tension rod, respectively.
