A composite tube made from a combination fiber and epoxy is disclosed. The tube may be made by filament winding although other materials and processes are suitable. In one example, the tube laminate is a mix of axial and helical fibers tailored to meet the stiffness and strength requirements of the particular application. Fibers having a different modulus may also be mixed to meet axial and torsional stiffness requirements. For example, high modulus fibers may be used in a helical pattern to handle high torque loads while lower modulus fibers may be used for the remaining portion of the tube laminate. The composite tube may be used for load and/or torque bearing applications and can include a support tube pressed fit into an end of the tube.

Composite tube for torque and/or load transmissions and related methods

Methods, devices, and systems of downhole tools are disclosed. The tools each has a sleeve attached to a mandrel to form a composite frac or bridge plug or similar coupling to a downhole tool tubing product without the use of shear pins. The engagement between the mandrel and the sleeve includes a load breaking ledge, threads, ring and groove combination, and helical spiral groove with a helical coil.
