TORQUE ROD

PARTNER: SKF AEROSPACE

APPLICATIONS:  Structural parts for aircraft and satellites

CONCEPT:
To allow the recovery of the torsion, the concept has been designed by C&T in a symmetrical arrangement around the main axis of the part to be produced . This geometrical organization transforms the traction and compression in each strap to torsion around the revolution axe. The torque will therefore causes « pure » stresses in the fiber as in the resin .

C&T has designed a fiber placement automated machine producing continuously, which allows the manufacturing of a composite part having an ideal orientation for the torsion recovery  in the current section of the tube and ensuring ends adapted to the concept previously exposed .

SKF AEROSPACE has already started the industrialization of this concept . The first technical perspective is very encouraging : a rod with a nominal diameter of 30 mm is capable of transmitting a torque of 500 Nm, while having a currently unmatched mass.
