Abstract

The elongated stabilization member comprises a composite rod (R) having a uniform cross-section essentially throughout its length. The rod (R) has at least first and second segments (A, B, C) each of which has a different modulus of elasticity. Preferably the rod (R) is comprised of plastic with carbon fibers disposed therein and said first and second segments (A, B, C) have different orientation densities of fibers or lengths to provide said different moduli of elasticity.
