New Headliner Composites with Improved Acoustical Performance 980946
The substrate selection for headliner composites is driven by acoustics, systems integration, weight and cost considerations. However, the acoustical contribution of headliners plays a primary role in their design.
This paper highlights the acoustical contribution of the various headliner composites. Various current headliner composites based on glass-fiber mat, polyurethane foam, resinated reclaimed fiber composites are considered.
New composite structures are developed that exhibit good acoustical performance. The random incident acoustic evaluation is performed in an alpha-cabin which serves as a small reverberation room.
