US Patent 8225704 - Armor with transformed nanotube material

http://www.freepatentsonline.com/8225704.html

A variety of proposals have been made over the years for the use of carbon nanotubes to achieve stronger and lighter armor. This latest patent come from NanoRidge Materials and teaches pressure and heat treatment of a ceramic/nanotube mixture to form the armor. Claim 1 reads:

1. Armor comprising ceramic material, the ceramic material having therein transformed nanotube material, the transformed nanotube material produced by subjecting a matrix of the ceramic material and nanotube material to sufficient pressure and sufficient heat to transform the nanotube material, at least one layer of ballistic fabric connected to the ceramic material, the at least one layer of ballistic fabric containing carbon nanotubes.
