摘要： A composite shaft or rod formed by filament winding. The composite shaft is a solid shaft and the filament winding does not involve a mandrel. A filament core can be suspended between rotatable spindles and the filament materials can be laid directly onto the filament spindle, without any mandrel. A plurality of payout eyes can be used to simultaneously lay filament materials onto the filament core. A bridge plug can be formed with the solid composite shaft located within the bridge plug shell of the bridge plug.

摘要： A method of manufacturing a high-pressure composite pressure vessel for high-pressure being at or above 70 bar (1000 PSI or 7 MPa) includes providing an expandable core vessel defining a hoop section between end domes. An aligned discontinuous fiber composite material is wrapped over the expandable core vessel aligning with a plurality of load paths present in the expandable core vessel being over the hoop section and end domes. The aligned discontinuous fiber composite material has fibers in a prepreg tape that are at least 5 mm in length to 100 mm in length or less. Next, a continuous fiber-reinforced composite is wrapped over the aligned discontinuous fiber-reinforced composite along the hoop section and not wrapped along the end domes. The expandable core vessel may be pressurized and heated to consolidate the composite overwrap. Finally, the vessel is cooled under pressure resulting in the high-pressure composite pressure vessel.

摘要： A method of producing a universal joint assembly. The method comprises providing a joining member for forming a universal joint, said joining member comprising a first pivot and a second pivot; applying continuous fibre reinforcement and a polymer matrix to a form including said joining member to create a single fibre-reinforced polymer structure in which the joining member is embedded; and splitting said single fibre-reinforced structure into a first fibre-reinforced polymer shaft and a second fibre-reinforced polymer shaft that are coupled together by the joining member to form a universal joint.
