Abstract
A self-locking retention system is provided for a composite rotor blade supported on a rotor hub. A radially extending, stud-like retention member is provided on the rotor hub. A composite thickness projects radially inwardly from the rotor blade and substantially surrounds the retention member. The composite thickness is woven in a pattern which grips the retention member in response to outward forces applied to the rotor blade and the woven composite thickness.
