Hybrid golf club shaft

A hollow golf club shaft of circular cross section comprising at least one tubular cover layer comprising at least one isotropic material, and at least one tubular core layer comprising at least one reinforcement material chosen from carbon fibers, graphite fibers, glass fibers, quartz fibers, boron fibers, ceramic fibers, ceramic whiskers, metal-coated fibers, ceramic-coated fibers, diamond-coated fibers, carbon nanotubes, extended-chain polyethylenes, poly-p-phenylenebenzobisoxazole fibers, metal fibers, polythenes, polyarylates, polyacetals, liquid crystalline polymers, aromatic polyesters, and polyallylates, the reinforcement material being impregnated with at least one vibration damping thermosetting or thermoplastic resin chosen from epoxy, polyester, polystyrene, polyurethane, polyurea, polycarbonate, polyamide, polyimide, polyethylene, polypropylene, polyether, polyvinyl halide, polyvinylidene halide, nylon, nylon 6, polyphenylene sulfide, polyether ether ketone, polyether ketone ketone, polyamide imide, polyether imide, polyaryl sulfone, polyether sulfone, and liquid crystal polymer, wherein the vibration dampening thermosetting or thermoplastic resin has a loss factor of between about 0.2 and about 1.2 at 100 Hz and 68° F., a storage modulus of at least about 1,000 psi, and a Young's modulus of at least about 0.01 Mpsi, the cover layer and the core layer are conjoined and coextend substantially the entire length of the shaft, and the cover layer at an upper butt portion has a thickness of 0.001 inches to about 0.2 inches.
