ABSTRACT:
A method for forming a structurally reinforced panel member, and the panel itself, is disclosed. The method requires disposing a first set of sheets of curable composite material atop a tool forming surface, wrapping a plurality of mandrels with a second set of sheets of curable composite material, arranging the wrapped mandrels in side by side relation atop the first set of sheets, curing the structural assembly, and then removing the mandrels from the cured structural assembly. In this way, the structural assembly includes interior channels obtained when the mandrels are removed from the cured structural panel member. The material portions defining the channels provide increased strength for the structural assembly.
