ABSTRACT:
In a filament winding technique, filaments are wound around a mandrel, and the mandrel remains in the structure and becomes part, normally a structural part, of the article. The mandrel may be any suitable rigid, light-weight material, but a foamed material such as a structural foam is thought to be most suitable. Metal inserts for attaching other components to the filament wound article can be moulded into the mandrel surface, and locked in place by the filament windings. According to a preferred aspect of the invention a motor vehicle suspension wishbone is made according to such filament winding method and the mandrel on which the filaments are wound remains in the structure.
