Abstract
In a method of making a linear composite member, a hollow carrier is provided having a cavity and an inner surface. A curable liquid or gelled resin is applied to the inner surface. A curable foam is introduced into the cavity. The foam contacts the resin when the resin is not more than partially cured, and preferably when the resin has a viscosity not greater than 250,000 centipoise at 25.degree. C. The foam and resin, which are preferably both polyurethanes, are cured together to form a linear composite member having a foam core and a hard resin skin formed integrally. In a preferred embodiment, a reinforcement material, such as a glass fiber web, is embedded in the resin skin.
