Abstract
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.
