Novel organophosphorus flame retardants for advanced composite applications
For future applications of epoxy resin systems for advanced composite applications it is necessary to have good processing and good FST (fire smoke toxicity) characteristics to meet fire safety requirements. Costs play an important rule also. The purpose of this study was to develop novel organophosphorus flame retardants (FR) which improve the FST properties of the material without affecting the mechanical performance. Epoxy resin systems with novel organophosphorus flame retardants have shown to be superior in comparison to epoxy resin systems with commercial phosphorus flame retardants with regard to fire smoke toxicity characteristics, processing and mechanical behaviour. The epoxy resin systems were characterized by TGA, DMA and cone calorimetry. The flame retarded systems have shown to be superior in comparison to epoxy resin systems with commercial phosphorus flame retardants with regard to fire-smoke-toxicity characteristics and mechanical behaviour. Very good flame retardancy was found already at low concentration. The effectiviness of organophosphorus flame retardants depends not only on the amount but on the chemical structure of the phosphorus compound and its decomposition behaviour also.
