    摘要： A shaft assembly comprising an elongated member having at least a portion which is hollow, tubular, shell like having an inside surface defining a shaft core and an outside surface defining a shaft functional surface, the shaft core being filled with a hardened, moldable material, and the shaft functional surface having at least one functional feature thereon, which is of hardened, moldable material integrally molded with the hardened, moldable material in the shaft core. In a preferred embodiment the shaft assembly is rotatable and has at least one molding aperture gate extending through the shaft from the inside surface to the outside surface which is filled with hardened, moldable material which connects the hardened material in the shaft core and functional feature, the tubular shell like member having a helical pattern cut through from the inside surface to the outside surface in that portion adjacent the at least one aperture gate and underneath the at least one functional feature to enable the portion to be flexible and deformable when placed under pressure against a surface.

    摘要： A method is provided of designing and producing a carbon fiber composite wrist pin using a combination of a carbon fiber composite pultruded rod that is overwrapped with a carbon fiber prepreg fabric. The use of the carbon fiber pultruded rod and the carbon fiber prepreg fabric results in a rod with optimal flexural strength properties to endure the flexural stress placed on a wrist pin during the cycling of an internal combustion engine. In addition, the overwrapping of the pultruded rod with a carbon fiber prepreg fabric allows for one pultruded rod blank to produce multiple wrist pin sizes by allowing one to change the outer diameter of the wrist pin by changing the thickness of the carbon fiber prepreg fabric overwrapping. After overwrapping, the rod blank is cut to a chosen specific length, optionally inserted into a metal sleeve, and coated with a thermal barrier coating. The wrist pin is then ground to a chosen specific tolerance and coated with an anti-friction coating.

    摘要： A tube arrangement includes a composite tube defining a centerline axis, wherein the composite tube comprises a proximal surface and a distal surface, and an end fitting comprising a first end disposed within the composite tube and a second end extending from the composite tube, wherein an outer surface of the end fitting defines a flared portion defining a terminus of the first end, a lobe portion disposed axially from the flared portion, and a terminating portion disposed axially from the lobe portion, the proximal surface conforms to a geometry of the outer surface of the end fitting, the lobe portion and the flared portion mechanically lock the end fitting to the composite tube to mitigate movement of the end fitting relative to the composite tube.

    摘要： A railroad crosstie (tie) may be fabricated from a composite material including a fiber reinforced polymer shell manufactured by pultrusion or other process, and filled by a suitable material, typically selected from expanded elastomeric polymer (such as polyurethane resin or other polymer), concrete, lightweight concrete formed by conventional aggregate, sand, cement, water, and an ultra light filler such as natural materials, sawdust, beads of expanded polymer such as expanded polystyrene, microspheres of glass or plastic, a recycled wooden tie in conjunction with any of the above, or the like. Fasteners may be driven such as spikes, threaded, such as screws, lag screws, spreading screws, rivets, or the like into apertures, pilot holes, or directly into fill absent apertures therein.
