Reaction to fire of CFRP and GFRP epoxy composites in bench-scale

The fire performance of two types of fiber-reinforced epoxy composites (GFRP and CFRP) was determined in bench-scale using cone calorimeter in two incident heat fluxes 35kW/m2 and 50kW/m2. The main reaction to fire properties including time to ignition (TTI), mass loss (ML), total and rate of heat release (THR and PHR) Smoke parameter (Av.SEA), carbon monoxide and carbon dioxide yields (COY and CO2Y), were evaluated and discussed. The results showed despite that the reinforced fibers are noncombustible, due to the combustible nature of epoxy resin, TTI values are low and PHR values are high. This study clearly shows the importance of fire properties improvement using fire retardants additives for FRP composites. Regarding to increasing FRP composites application for strengthening and rehabilitation of structures, the limitations of their applications should be determined based on the fire safety requirements in buildings and other applications
