Abstract: A composite fan blade for a gas turbine engine, the blade comprises a root portion for connecting the blade to a hub and an aerofoil portion. The aerofoil portion comprises an external cover formed from a non-metallic material and an internal structure enclosed within the cover. The internal structure comprises a plurality of support members extending generally from a pressure side of the internal structure to a suction side of the internal structure, and wherein the plurality of support members define a plurality of cells or channels.

Abstract: A method of manufacturing a hollow aerofoil component for a gas turbine engine includes using a capping panel to cover a pocket in a pocketed aerofoil body. An activation material is placed between the capping panel and the pocketed aerofoil body, and the temperature of the assembly is raised to a bonding temperature. The capping panel and pocketed aerofoil assembly are thereby joined together using activated diffusion bonding to form the hollow aerofoil component.
