Indianapolis, IN--Just how safe can you make an aircraft from the threat of fire and yet shield passengers from unwanted noise? E-A-R Specialty Composites feels it can offer aircraft skin damping composites that do both.
Not only do the company's composites comply with the most stringent federal aviation burn tests, but they provide lightweight, high-damping performance on fuselage skin, bulkheads, and thin composite panels. The materials combine damping sheets and foams with an aluminum constraining layer and pressure-sensitive adhesive. Several different formulations enable general and commercial aviation companies to "tune" the materials for their specific temperature and damping performance requirements.
E-A-R has a long history of providing the damping materials to aircraft designers. Among its long list of customers: Cessna, Gulfstream, Learjet, Canadair, Airbus, Bell Helicopter, and McDonnell Douglas.
