摘要： A unique material is disclosed for use in trim panels, such as headliners. The unique material includes a central polyester honeycomb core, and outer polyester layers providing and I-beam construction. In a most preferred embodiment of this invention, the layers are all formed of polyester such that portions trimmed away from the panel are easily recycled. In addition, since the honeycomb core is formed of a thermoplastic, it is easily molded to desired shapes. The honeycomb core provides good strength to weight characteristics and also good acoustic characteristics.
