dovetails sections 22 fig4 exhibits three dovetail sections labeled dovetail sections 22a 22b and 22c different numbers of dovetail sections may of course be implemented without deviating from the spirit of the present invention the dovetail sections 22 are separated by discrete cutouts 24 which are for the purpose of accommodating unidirectional composite material 26 how composite material 26 is laid and positioned in the dovetail former 21 is discussed subsequently the concave side of the airfoil 30 abuts the convex side of the airfoil 32 the concave side of the airfoil is regarded as an airfoil pressure surface and the convex side of the airfoil is an airfoil suction surface each metallic dovetail section 22 separates sections of unidirectional composite material 26 which are laid in layers from the convex side of the airfoil to the concave side in other words each metallic dovetail section form is positioned between sections of unidirectional fiber material 26 between each dovetail section 22 is a cutout 24 three of which are portrayed in fig4 by filling the cutouts 24 with layers of unidirectional composite material 26 which are laid from the convex side of the airfoil to the concave side of the airfoil the open space between dovetail sections is filled in each dovetail section such as dovetail sections 22a 22b and 22c fig4 have a front side and a back side fig4 identifies back side 25 of dovetail section 22c the front side of dovetail section 22c.
