Abstract: In accordance with at least one aspect of this disclosure, a drive shaft includes, a first tube body having one or more first body channels defined through a wall thickness thereof, the one or more channels configured to increase bending and/or axial flexibility of the first tube body while only allowing for a less than proportional reduction in torsional stiffness of the first tube body. A second tube body can be concentrically disposed relative to the first tube body and connected to the first tube body at a first end portion and a second end portion. The second tube body can include one or more second body channels defined through a wall thickness thereof, the one or more channels configured to increase bending and/or axial flexibility of the second tube body while only allowing for a less than proportional reduction in torsional stiffness of the second tube body.

Abstract: A process for forming a flexible composite driveshaft includes providing a mandrel having a rigid region and a compressible region, applying fiber tape to the mandrel using automated fiber placement with in-situ laser curing in the rigid region and without in-situ laser curing the compressible region, and compressing the fiber tape and compressible material in the compressible region to form diaphragms that extend radially outward to a diameter that is at least twice the size of a diameter of the composite driveshaft in the rigid region.

Abstract: A drive shaft has a central tubular portion formed of a polymer composite with imbedded fibers. It extends between a first end and a second end. The central tubular portion has an outer peripheral surface. There is at least one ring on the outer peripheral surface of the central tubular portion. A method of repairing a composite material tube includes the steps of (a) identifying a damaged area on a composite tube, and (b) placing a patch on a surface of the tube and over the damaged area.

Abstract: Composite shafts and methods of making the same are described. The composite shafts include a plurality of composite elements arranged about an axis. The composite elements include first and second groups arranged at offset angles ±α. The groups of composite elements are configured to cooperate to allow the shaft to be flexible under bending and/or axial load and stiff under rotational load. The hollow shaft includes one or more axisymmetric radially-outward undulating portions and one or more axisymmetric narrow portions. The composite elements of groups are connected together in the radial direction along the narrow portions and the composite elements of the groups are not connected together in the radial direction along the undulating portions.

Abstract: A method of testing a part includes placing a first member on a part to be tested. A second member is placed on an opposed surface of the part. One of the members has an ultrasonic transmitter and the other has an ultrasonic receiver. At least one of the members has at least one magnetic element and the other has at least one of a magnetic element or a ferromagnetic metallic element which is attracted to magnets. One of the members moves along the surface of the part such that magnetic attraction causes the other to move along the opposed surface of the part with the one of the members. A controller causes an ultrasonic signal to be sent from the transmitter through the part to be tested which is received by the receiver and then analyzed by an ultrasonic testing machine.
