    Abstract: Use of a resin system for making a composite material in a liquid moulding process. The resin system comprises an epoxy component and at least one curing agent, and at least 35 wt. % of the epoxy component is one or more naphthalene based epoxy resin. There is also provided a cured composite material, and a method of making the cured composite material in a liquid moulding process which comprises placing fibre reinforcement and the resin system in a mould and curing. The resin system and the methods of making a cured composite material are particularly applicable to liquid moulding processed such as resin transfer moulding (RTM), vacuum assisted resin transfer moulding (VARTM), Seeman composite resin infusion moulding (SCRIMP), resin infusion under flexible tooling (RIFT), and liquid resin infusion (LRI).

    Abstract: Formulations comprising from 10 to 80% by weight of the formulation of a halogenated epoxy resin; from 1 to 15% by weight of the formulation of an antimony based fire retardant; from 1 to 10% by weight of the formulation of an inorganic or non-polymeric organic phosphorous containing fire retardant; and from 1 to 30% by weight of the formulation of a curative system are provided. The formulations are particularly suitable for producing aircraft interior composite components having good fire retarding properties, low smoke emission, low smoke toxicity and low heat release properties. The formulations also have excellent processing and mechanical properties. Further components may be included in the compositions to improve various properties, including the fire retarding, low smoke emission, low smoke toxicity and low heat release properties and to also further improve the processing and mechanical properties, including toughness. Compositions produced from the formulations have excellent processing and mechanical properties, and may also have good surface finishes.
