Abstract
The invention relates to a shaft for a golf club, or to a club equipped with such a shaft. On at least 30% of the length of the shaft, its peripheral wall includes at least two layers, i.e., a first layer made of a material of density (.rho.1) and of longitudinal Young's modulus (E1), and a second layer made of a material of density (.rho.2) and of longitudinal Young's modulus (E2), the first and second layers being separated by a separation layer made of a substantially isotropic material having a density (.rho.3) and a longitudinal Young's modulus (E3), the densities (.rho.1, .rho.2) of the materials of the first and second layers being greater than the density (.rho.3) of the material of the separation layer, the longitudinal Young's moduli (E1, E2) of the materials of the first and second layers being respectively greater than 20 GPa, and the longitudinal Young's modulus (E3) of the material of the separation layer being lower than 20 GPa.
