abstract The high specific stiffness and strength of composite materials with ultra-high modulus (UHM) carbon fibers as well as the possibility of creating a load-adapted property profile are ideally suited for the design of advanced transmission shafts for mobile applications. For a reliable development of such safety relevant components, material properties under static and dynamic loading conditions as well as adapted manufacture processes, which ensure a reproduceable quality, are required. Therefore, extensive fracture tests were carried out under multi-axial loading in order to determine the static and dynamic strength behaviour of UHM-carbon fiber reinforced polymers. Additionally, an advanced construction concept for fibre- -reinforced transmission shafts in combination with an adapted winding process was developed, which enables the integral manufacture of advanced lightweight transmission shafts.
