  • Composite propeller blade with unitary metal ferrule and method of manufacture
    Patent number: 6666651
    Abstract: Composite blade assembly 10 for a propeller assembly for an airplane, including unitary metal ferrule 50 attached to a fiber-reinforced composite blade 20; and a method for manufacturing blade assembly 10. Internal pressure molding includes unitary ferrule 50 as part of mold 81 and bladder 90 pressurizes composite material 31 from within. Blade 20 is retained within inner bore 53 of unitary ferrule 50 by adhesion of the epoxy matrix and by grooves 55. The method of manufacture creates a cured blade assembly 10 that requires little or no post-machining.
