Abstract
The invention covers a laminated composite shaft formed by blending composite materials having high-bending modulus reinforcements with materials having a lesser or intermediate bending modulus. The shaft comprises a plurality of windings superimposed one upon the other. The windings having reinforcements with a high-bending modulus are sandwiched in between windings having reinforcements with an intermediate bending modulus. The orientation of the reinforcements within the composite materials in relation to the axis of the shaft are disclosed.
