Abstract
The low-inertia and high-strength accelerating lever comprises a hub part, arm and end part made of a thermoplastics reinforced by high-strength fibers. The lever is built up from a number of layers in the form a Prepregs or semifinisheds, which are placed one on another, the layers having different fiber orientations and extending substantially parallel to the movement plane. Longitudinal components of the fiber orientations predominate in the arm with a gradual transition to the hub part and end part; the hub part and end part having a substantially isotropic distribution of the fiber orientations.
