High Volume Reinforced Low Cost CMC's

The proposed Phase I SBIR program will result in the development of an innovative, net shape processing technique which enables nanolevel control over composite compositions combined with independent rnacrolevel control over microstructures to achieve improved ceramic matrix composite materials The program will result in higher strength and modulus, lighter-weight, more environmentally resistant, and lower cost composite materials that can be fabricated net shape using traditional pressure assisted sintering techniques Specifically, Powdermet will demonstrate the fabrication of 30-60 v% SiC reinforced alumina composites showing improved strength, modulus, reliability, and durability Cost improvement over alternate materials will be demonstrated through an unique processing approach enabling very high reinforcement contents, combined with low cost net shape fabrication techniques.
