Abstract
Content

Sintered fiber metal composites are used in aircraft as an acoustic media within environmental ducting, inlet and exhaust systems. The material can be engineered to meet specific acoustic attenuation and noise reduction goals within these applications. Sintered metal fiber composites have proven reliable and effective since the 1950's, but continue to deliver new value through ongoing investment and new use cases.

There are four design options for mitigating noise in the turbine gas flow and in the environmental control system (ECS) of aircraft. In some applications, the use of sintered metal fiber composites may be the most cost- or space-effective approach, deliver unique ancillary benefits or perform better than other technologies that can survive the requisite temperatures.
