Abstract
A headliner made from a laminate comprising a core layer sandwiched between two stiffening layers to form an I-beam construction that provides the necessary strength for the headliner. The core layer is preferably a blend of nonwoven fibers including some fine denier fibers to provide improved sound absorption properties. The stiffening layers also comprise a blend of nonwoven fibers. Both the core layer and the stiffening layers include some binder fibers to bond together the various fibers within each layer and the layers to each other.
