<p>A structural panel for a vehicle or building contains a substrate and a layer of flame-resistant polybenzazole polymer. If the substrate is heat-resistant, the panel can serve as a fire barrier. If the substrate is not heat-resistant, the polybenzazole layer can still serve to delay ignition and contain any volatile gases and molten polymer that forms when the panel is subjected to heat.</p> |
