Abstract
A composite helicopter hub yoke is described. The yoke is made up of glass fibers unidirectionally oriented in the direction of principle stress, i.e. along the length of the yoke. The yoke also has clevis sections on either end and the clevis sections additionally contain multiaxially oriented multiple plies of unidirectionally oriented continuous graphite fibers interleaved with the unidirectionally oriented continuous glass fibers to produce crack resistance, damage tolerance, and integrity inspectability.
