Abstract
A method of molding complex composite articles having skin portions containing fibres to be injected with a resin and a core portion includes providing one or more galleries in the core or fibre skin and injecting resin into the gallery or galleries whereby it is rapidly transmitted to all portions of the skin. The galleries overcome the resistance to flow created by the capillary nature of the fibrous layer and enable more rapid mold cycles to be employed and more complex articles therefore to be molded.
