With the in-house implementation of a carbon-SMC shaft drive Blackwave demonstrated that carbon-SMC is capable of being used for highly-stressed components. It was important to create a design that is able to handle the calculated torque loads.


The carbon-SMC technique provides geometrical possibilities that the biggest part of the tripod joint could be made of carbon-fiber-reinforced plastic in one integral process. Connecting the joint with the carbon continuous fiber reinforced composite shaft has been implemented with an adhesive bonding technique. Bearing shells made of tempered tool steel were used for the load introduction at the contact points. The assembled shaft drive has been examined on the test bench and could handle the necessary torque.
