ABSTRACT:
Thermoplastic resin sheets, particularly in the form of fiber-reinforced composites, have adherent cap layers, at least one of which comprises an intumescent polydiorganosiloxane-containing barrier material which forms upon ignition a thermally stable foamed char layer. Such articles have improved fire resistance in comparison with similar articles having no cap layer or non-intumescent cap layers.
