Title: The effect of traditional flame retardants, nanoclays and carbon nanotubes in the fire performance of epoxy resin composites
Issue Date: 2017
Abstract: The effectiveness of distinct fillers, from micro to nano-size scaled, on the fire behaviour of an epoxy resinand its carbon fibre reinforced composites was assessed by cone calorimetry. The performance was compared not only regarding the reaction to fire performance, but also in terms of thermal stability, glass transition temperature and microstructure. Regarding the fire reaction behaviour of nanofilled epoxy resin,anionic nanoclays and thermally oxidized carbon nanotubes showed the best results, in agreement with morecompact chars formed on the surface of the burning polymer. For carbon fibre reinforced composite plates,the cone calorimeter results of modified resin samples did not show significant improvements on the heatrelease rate curves. Poorly dispersed fillers in the resin additionally caused reductions on the glass transitiontemperature of the composite materials.
