Resumo: An experimental programme was performed in order to evaluate the behaviour of composite materials when exposed to fire, in particular composite materials based on carbon fibres (CFRP). Therefore, a campaign of tests on concrete specimens with 100×100×40 mm was developed. The CFRP sheet is bonded on the surface of the specimens using epoxy resin and exposed to thermal action. The influence of passive protection systems on the burning behaviour of CFRP is analysed using different fire protection materials, such as gypsum plasterboard and intumescent paint. The surface of the reinforcement system is exposed to the action of different radiant fluxes equal to 35 kW/m2 and 75 kW/m2, from a cone calorimeter. The temperature evolution is determined by thermocouples placed between the concrete surface and CFRP, allowing to analyse the influence of these protective materials in the structural reinforcement capabilities of the CFRP when subjected to high temperatures.
