TL;DR: In this paper, the fire response of a potassium aluminosilicate (Geopolymer) matrix carbon fiber composite was measured and the results compared to organic matrix composites being used for transportation, militar y, and infrastructure applications.
Abstract: The fire response of a potassium aluminosilicate (Geopolymer) matrix carbon fiber composite was measured and the results compared to organic matrix composites being used for transportation, militar y, and infrastructure applications . At irradiance levels of 50 kW/m 2 typi- cal of the heat flux in a well developed fire, glass- or carbon-reinforced polyeste r, vinylester, epoxy, bismaleimde, cyanate ester, polyimide, phenolic, and engineering thermoplastic laminates ignited readily and released appreciable heat and smoke, while carbon-fiber reinforced Geopolymer com- posites did not ignite, burn, or release any smoke even after extended heat flux exposure . The Geopolymer matrix carbon fiber composite retains sixty-seven percent of its original flexural strength after a simulated large fire exposure.
