ABSTRACT:
A dynamically balanced drive shaft. The shaft is preferably formed of fiber reinforced resin and is designed to operate at speeds below the first critical speed. To balance the shaft, a mass or patch of resin containing high density particles, such as metal particles, is applied to one or more locations on the shaft. The patch extends only a portion of the circumference of the shaft and generally has an area less than 10 sq. inches, and generally has a thickness less than 1/16th inch.
