Abstract
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.
