Abstract

A method of manufacture of a structural member comprising, providing a number of internal elements (16,18,20), each having an aperture formed therein, sequentially assembling the internal elements onto a longitudinal element (14) such that the longitudinal element passes through the aperture of each internal element, and wrapping an outer skin around the assembled internal elements and longitudinal element. A structural member is thus produced having a number of internal elements, each internal element having a longitudinal axis aligned with the longitudinal axis of the remaining internal elements, and having a continuous outer skin formed over the internal elements.
