Ultramet’s work in melt infiltration of refractory ceramic matrix composites (CMCs) is featured in the August 2014 issue of Ceramic Industry.
Refractory CMCs are of considerable interest for a range of high temperature and severe environment applications. Ultramet's melt infiltration process promotes rapid, cost-effective fabrication of CMCs.
For more than a decade Ultramet manufactured rhenium components for the solid divert and attitude control system of the Standard Missile-3 (SM-3), Block IA, the Navyís mobile ballistic intercept system.
On February 20, 2008, the Navy used the SM-3 to intercept a broken spy satellite and explode the satelliteís tank carrying toxic hydrazine rocket fuel. Right, launch of SM-3 from USS Lake Erie (CG 70) on February 20, 2008.
Ultrametís open-cell ceramic foam was an enabling technology for a modified RV-4 aircraft that won the $50,000 Noise Prize in the 2007 CAFE Foundation’s NASA Personal Air Vehicle Centennial Challenge on August 11, 2007, in Santa Rosa, California. The muffler on the RV-4 was lined with Ultrametís silicon carbide foam broadband sound absorber and was built using Ultrametís assembly techniques. While flying at 192 mph, the aircraft operated at a noise level three times quieter than that of most small aircraft.
Ultramet’s work in advancing structural thermal protection systems, particularly for the scramjet, is included in the 2007 edition of AFRL Technology Milestones. Published annually by the Air Force Research Laboratory (AFRL) at Wright-Patterson Air Force Base (Ohio), AFRL Technology Milestones is used by AFRL to inform leadership and the general public of significant technology advances and revolutionary developments in the Air Force research program
