Abstract
A thin compressor blade used in a small aircraft gas turbine engine, in which the blade includes a main blade portion formed from a fiber reinforced resinous composite material to provide a lightweight and strong blade, and in which the leading edge or the trailing edge of the blade is formed from a foam metal reinforced composite material that defines a sharp edge for improved performance of the thin blade. The fibers of the main body extend into the edge region in order that the resin used to bind the foam metal will also bind with the fibers of the laminates to secure the edge to the main blade body. The blade tip can also be formed from the porous foam metal and resin material to make a strong and lightweight rotor blade.
