Abstract: A tubular composite structure for transmitting forces comprises a metal tubular core, preferably of aluminum, having a layer of structural metal adhesive on the exterior surface of the core. On top of the structural adhesive layer are alternating laminae of resin impregnated unidirectional reinforcing fibers, particularly carbon or graphite fibers, and of woven fiberglass, beginning with a layer of woven fiberglass followed by a lamina of resin impregnated continuous unidirectional reinforcing fibers and continuing in alternating fashion but ending with a final layer of resin impregnated continuous unidirectional reinforcing fibers, each successive layer of resin impregnated continuous unidirectional fibers having the fibers oriented at an angle of between about 5.degree. to 12.degree. with respect to the longitudinal axis of the metal tube and in opposite orientation with respect to the next preceding layer. The fibers in the woven fiberglass layer are oriented at 0.degree. and 90.degree.

Abstract: A composite golf shaft for use with a metal golf club head is improved by reinforcing the tubular metal core of the shaft with a unidirectional graphite fiber reinforced resin body which is inserted in the tip section of the shaft.

Abstract: A novel golf shaft having a metal core and a graphite fiber reinforced sheath thereon is provided. The shaft has a predetermined orientation of the graphite fibers. In one embodiment, some longitudinal fibers are located in the region where the butt section of the shaft begins to taper downwardly thereby lowering the bending profile of the shaft compared with a shaft not having the longitudinal fibers. The method of fabricating the shaft also is disclosed.

Abstract: A method of making a novel ski having viscoelastic properties is disclosed. The ski is composed of continuous reinforcing fibers embedded in a matrix of an elastomer modified syntactic plastic foam. The fibers are arranged so as to be at an angle of 0.degree. and 90.degree. with respect to the longitudinal axis of the ski.

Abstract: A game racket is provided that has high bending and torsional stiffness. The racket has a central core and a fiber reinforced plastic skin on the core. The fiber reinforced plastic skin is generally disposed on the faces of the core parallel to the striking plane and covering at least the head portion and the throat sections of the racket. The fibers are continuous and layered. The fiber in the throat section is crossplied at alternating angles as measured from the longitudinal axis of the racket frame. The fibers on the surface of the head portion are aligned with the general contour of the head portion.
