Abstract
Abstract Rigid lightweight composite panel. The panel comprises a honeycomb core with thin imperforate facing sheets bonded thereto, and sheets of lightweight polyvinyl chloride (PVC) having a foamed center and smooth matte surfaces. The PVC sheets are bonded to the facing sheet by thin layers of pressure sensitive adhesive material which is adhesive on both sides. The panels are useful as custom exhibits and for other purposes.
