Composite headliner with improved acoustic performance
摘要:
A composite headliner material allows sound waves originating within a vehicle to penetrate deeply into the headliner where all of a significant portion of their energy is absorbed rather than reflected back into the vehicle. The coverstock sheet is backed by a multilayer material with a foam core coated above and below by a fibrous glass mat impregnated with an adhesive with scrim layers above and below glass mat layers.
