Abstract
In a hollow cylindrical structural member consisting of resin impregnated fibers wound in alternate layers of circumferential and helical windings disposed on top of one another and having reinforcing support ring structures formed at its axial ends by additional circumferential windings, the additional windings include inner and outer layers of windings of different strength fibers wherein the fibers of the outer layers have a modulus of elasticity which is smaller than that of the fibers of the inner fiber layers so that, particularly for use with high speed rotors, the centrifugal forces do not cause separation between outer and inner layers.
