A method of forming a composite component is provided. The method includes locating a fibrous preform, providing a slurry, mixing the slurry with sacrificial fibers, injecting the slurry into the fibrous preform, heating the fibrous preform, forming channels in the fibrous preform, and densifying the fibrous preform. The sacrificial fibers are suspended in the fibrous preform along an injection pathway such that heating the sacrificial fibers forms the channels along the injection pathway as the sacrificial fibers are burned away.

A forging apparatus includes an ironing mechanism and a phase alignment mechanism. The ironing mechanism includes: a punch set, which is fitted into a cylindrical portion of a pre-processing material to be formed into the outer joint member, and is radially expandable and contractible, the cylindrical portion having grooves formed in an inner peripheral surface thereof; and a die having a hole into which the cylindrical portion is press-fitted. The phase alignment mechanism is configured to align phases of the grooves in the inner peripheral surface of the pre-processing material and phases of track groove portion forming surfaces of the punch set with each other before the pre-processing material is fitted to the punch set.

A method for manufacturing a braking band may include providing a braking band with a base band having an upper face and a lower face, where the base band being is made of titanium or titanium alloy. The method may also include directly depositing a material in particulate form consisting of ceramic and metal and/or intermetallic particles above at least the upper face and/or the lower face so to create an upper coating layer and/or lower coating layer. A braking band for a brake disc may have a base band entirely made of titanium alloy and having an upper face and a lower face, an upper coating layer, and a lower coating layer joined to the base band along the lower face. The upper coating layer and the lower coating layer consist of a mixture of ceramic and metal and/or intermetallic particles.

A one way clutch with an integrated spring is disclosed. The assembly includes an inner ring and an outer ring, one of which has a ramped portion. A cage defines a plurality of rolling element pockets, and includes first and second sidewalls each having an integrated tab. Rolling elements are biased by the integrated tabs toward both the inner and outer rings. The force angle of the integrated tabs is calibrated for a predetermined application.

A steering shaft assembly includes a male shaft having a plurality of splines formed thereon, each of the splines terminating at a spline end, wherein each of the spline ends form an angle of about 90 degrees relative to a longitudinal direction of the splines. The steering shaft assembly also includes a female shaft including a plurality of stakes located proximate an end of the female shaft, the stakes retaining the male shaft at an interface between the stakes and the spline ends.

A method for manufacturing a brake disc includes providing at least one sheet of predefined thickness, blanking a first disc-shaped portion in the at least one sheet adapted to make a first plate of a ventilated braking band, blanking a second disc-shaped portion in the at least one sheet adapted to make a second plate of the ventilated braking band, blanking a third portion in the at least one sheet adapted to make at least one ventilation spacer for the ventilated braking band, drawing the third portion by shaping first and second protrusions, forming opposite first and second recesses adapted to make ventilation channels, connecting the first disc-shaped portion to the first protrusion by discontinuous weld spots, and connecting the second disc-shaped portion to the second protrusion by discontinuous weld spots.

A method for manufacturing a composite brake disc (1), comprising shaping a bell (2) through deep-drawing of a metal sheet (20), forming at least one groove (22) in a surface of a bottom portion (24) of the metal sheet (20) and, then, pushing the bottom portion (24) relative to an outer portion (25) in a retro-forming direction (23) opposite the drawing direction (20), connecting, a brake band (3) to the bell (2).

The present disclosure provides a fibrous preform, comprising an annulus having at least one of an outer diameter portion or an inner diameter portion, the outer diameter portion extending radially inward from an outer diameter of the fibrous preform and the inner diameter portion extending radially outward from an inner diameter of the fibrous preform. In various embodiments, the fibrous preform further comprises a medial diameter portion disposed between the outer diameter and the inner diameter, wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile. In various embodiments, the first needling profile is less than the second needling profile.

A device that employs shear forces to transmit energy includes an outer housing assembly, a disk, and a reservoir with a working fluid. The disk is received in and rotatable relative to the outer housing assembly. A working cavity is formed between a rotor portion of the disk and the outer housing assembly into which the working fluid is received to create shear forces. A plurality of flow altering structures are disposed on the outer housing assembly and are configured to reduce a thickness of a boundary layer of the working fluid in the working cavity in areas that are local to the flow altering structures.
