ABSTRACT:
Contoured load carrying filament reinforced matrix structure which may be in the form of an airfoil or hydrofoil and comprising a plurality of elongated coextensive tubes disposed in side-by-side relationship to form a tube assembly and individually of sufficient cross section to project substantially from one side to the other of the cross sectional contour of the foil with the opposite cross sectional extremities of such tubes cooperating to form a composite cross sectional contour defining the contour of such foil. A skin is wrapped around the composite tube assembly and is bonded thereto to secure such filament wound tubes in position and provide for good load distribution when such foil is loaded.
