ABSTRACT:
A method of manufacturing an elongated, multi-component structural member. A porous core is formed and a first layer of an air-tight skin is applied to the core. A second layer of peripherally extending fibers is applied to the first layer. A third layer of axially extending fibers impregnated with excess resin is applied to the second layer. A fourth layer of peripherally extending fibers which are resin-free is applied to the third layer and the resulting member is placed in a mold and cured. The excess resin from the third layer of fibers impregnates the fourth layer of fibers. An assembly of more than one core with fibers may be placed in the mold.
