US Patent 7832983 - Nano-reinforced carbon fiber housing for aircraft engines

http://www.freepatentsonline.com/7832983.html

Carbon fiber composites exhibit a superior strength to weight ratio in comparison to most metals used in aircraft design but can introduce processing difficulties. This patent from the Goodrich Corporation and Rohr Inc. teaches incorporating a variety of different nanomaterials into such composites to ease processing and further improve strength. Claim 1 reads:   

1. A nacelle or nacelle component for use in aircraft engines and comprising a composite material including carbon fibers, wherein the carbon fibers comprise from 0.1 to 20 percent by weight nanoreinforcement material.
