The article "Hybrid Gear Preliminary Results: Application of Composites to Dynamic Mechanical Components" appeared in the May 2013 issue of Gear Technology.

Summary
Composite spur gears were designed, fabricated and tested at NASA Glenn Research Center. The composite web was bonded only to the inner and outer hexagonal features that were machined from an initially all-metallic aerospace quality spur gear. The hybrid gear was tested against an all-steel gear and against a mating hybrid gear. Initial results indicate that this type of hybrid design may have a dramatic effect on drive system weight without sacrificing strength.
