ENGINEERED SOLUTIONS FOR DEMANDING ENVIRONMENTS® FELTMETALTM Acoustic Media PROVIDING SUPERIOR NOISE ATTENUATION SOLUTIONS Technetics FELTMETAL™ acoustic media is an engineered, porous material made of sintered metal fibers. The fiber size, porosity and thickness of the media combine to control the acoustic impedance in critical aerospace applications. Whether to satisfy FAA requirements or consumer demands, the attenuation of aircraft noise is a critical design consideration. Technetics’ acoustic media interacts with sound waves to internally scatter the energy and diminish noise and is an integral component in all the primary aircraft manufacturers’ acoustic treatment solutions. DESIGN FEATURES Fiber diameters ranging from 8μ Formable for complex designs Belly fairing inlet High oxidation and erosion resistance High temperature materials for exhaust silencers • Optimum performance through acoustical impedance matching Readily cleanable Exceptional performance at high frequencies Stainless steel for service temperatures up to 930°F [500°C] FeCrAlY for service temperatures up to 2000°F [1100°C] Corrosion resistance OPERATING PARAMETERS Reliable performance in wet conditions Ancillary moisture wicking benefits in ECS applications TECHNETICS GROUP EnPro Industries companies 1700 E.
