Abstract

A blade for a fan of a gas turbine engine includes an airfoil section that spans along a radial direction between first and second radial ends, and a dovetail at the second end of the airfoil section. The airfoil section and the dovetail are comprised of a fiber-reinforced composite that includes inter-section fiber plies that each extend from the airfoil section into the dovetail and wedges that are interleaved with the inter-section fiber plies in the dovetail. The dovetail is asymmetric about the radial direction and has first and second circumferential sides that are sloped to face radially outwardly and form non-zero angles with the radial direction. One of the non-zero angles is 10° or less and a sum of the non-zero angles is from 35° to 45°.
