This paper presents the latest results on the properties of GEOPOLYMER/CARBON composite, namely: * viscosity,
- chemical reactivity,
- differential scanning calorimetry,
- thermogravimetric analyses,
- mechanical properties (inplane shear, interlaminar shear, warp tensile, flexure).
It further compares GEOPOLYMER/CARBON composite to organic matrix composites being used for infrastructure and transportation applications. At irradiance levels of 50 kW/m2 typical of the heat flux in a well developed fire, glass- or carbon-reinforced polyester, vinylester, epoxy, bismaleimide, cyanate ester, polyimide, phenolic, and engineering thermoplastic laminates ignited readily and released appreciable heat and smoke, while carbon-fiber reinforced GEOPOLYMER composites did not ignite, burn, or release any smoke even after extended heat flux exposure. The GEOPOLYMER matrix carbon fiber composite retains sixty-three percent of its original flexural strength after a simulated large fire exposure.
