Abstract
The use of Carbon Fibre Reinforced Polymer (CFRP) composites have become a prominent solution for retrofitting the concrete structures. Though CFRP composites have superior mechanical properties, resistance of CFRP/Concrete composites to fire remains unsolved. The degradation of the epoxy resin at elevated temperature makes the FRP composites weaker due to the low glass transition temperature of epoxy resin. A review on CFRP-concrete composites at elevated temperature and available insulation systems are presented in this paper. The paper summarises the results obtained from experimental and numerical studies on the fire performance of CFRP-concrete composites. Hence, it was concluded that by providing appropriate insulation system, the CFRP-concrete members can be protected from fire. However, there are several drawbacks with available insulation systems, such as high cost, addition of dead load, and less aesthetic appearance which are also discussed in this paper.
