Abstract: A new developed high-performance flame retardant resin system for use to manufacture aircraft interior parts by RTM or infusion will be introduced in this paper. The inherent FST (Flame, Smoke and Toxicity) properties of this resin system come from its chemical structure and its high cross-link density as opposed to conventional flame retardant systems which rely on the presence of inorganic fillers and additives. This new resin system meets the FAR 25.853 vertical burn, smoke and toxicity requirements with both carbon and glass fiber reinforcement in various thickness configurations. The mixed two-component latent system with low viscosity at low working temperatures allows the production of small and large complex parts. The polyaddition reaction was tailored for cross-linking to yield quality composites without releasing any volatile by-products and suitable for VOC emission free working environment. This novel high-performance solution provides what may be considered as a new and improved value proposition for aerospace designs, providing a preferred alternative to metal in structural applications and phenolics in non- and semi-structural applications.
