in 2013, Rolls-Royce, the global power systems company, acquired Hyper-Therm High Temperature Composites, Inc., a producer of state-of-the-art composite materials, including ceramic matrix composites (CMCs), engineered coatings and thermal-structural components. Hyper-Therm HTC will become a wholly-owned subsidiary of Rolls-Royce, and will serve as the hub for technical development of CMCs, which will find applications in a broad range of future Rolls-Royce power systems.Hyper-Therm High-Temperature Composites uses patented Chemical Vapor Infiltration/Deposition (CVI/CVD) process technology. The use of these new materials in gas turbine engine components offer the benefits of strength at higher temperatures to reduce the requirement for cooling air. CMCs are also typically one third of the density of nickel super alloys which could significantly reduce the weight of components. This would mean more environmentally friendly engines with improved efficiency and reduced emissions.
