An additive manufacturing method includes providing a first composite material and forming a composite part matrix using the first composite material and defining a first layer, applying a first fiber reinforcing material to the composite part matrix atop and in contact with the first layer of the composite part matrix such that fibers of the first fiber reinforcing material are oriented in a first direction and form a second layer on the composite part matrix, applying a second fiber reinforcing material to the composite part matrix atop and in contact with the first fiber reinforcing material such that fibers of the second fiber reinforcing material are oriented in a second direction orthogonal to the first direction and form a third layer on the composite part matrix, applying the first composite material to the composite part matrix, and curing the composite part matrix to create a composite product.

Methods for composite part manufacturing

A transmission includes an input member, an output member, first and second interconnecting members, first and second countershaft members, a plurality of co-planar gear sets, and a plurality of torque transmitting devices. The torque transmitting devices include a plurality of synchronizer assemblies and a dual clutch assembly. The transmission is operable to provide at least one reverse speed ratio and a plurality of forward speed ratios between the input member and the output member.

Seven speed dual clutch transmission

A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. The torque transmitting devices include clutches and brakes including a selectable one-way clutch actuatable in combinations of two to establish a plurality of forward gear ratios and one reverse gear ratio.

Multi-speed transmission

A low mass, two piece planetary gear carrier having an integrated clutch housing comprises a first carrier flange and clutch housing and a second carrier flange which are secured together by a plurality of threaded fasteners extending through hollow dowels. A plurality of planet gears receive needle bearing assemblies which are, in turn, supported on pins or stub shafts. The stub shafts are retained in the carrier by transverse retaining pins received in the second carrier flange and extending into the shafts. Unitized washers are disposed between both faces of the planet gears and the flanges. The method of assembly is also a feature of the present invention.
