Fire-retardant composite materials

摘要

A prepreg for the manufacture of a fibre-reinforced composite material, the prepreg comprising:i. an epoxy-resin matrix comprising: a. at least one non-halogenated epoxide-containing resin which has been chemically modified with at least one of a nitrogen- and/or phosphorous-containing molecule which has been chemically reacted with the epoxide-containing molecule; b. at least one toughening additive comprising an elastomeric or thermoplastic material chemically reacted with the at least one epoxide-containing resin; c. at least one mineral filler to provide fire-retardancy; and d. at least one catalyst for curing the epoxide-containing resin; andii. a fibrous reinforcement at least partially impregnated by the epoxy resin matrix. The prepreg is used for manufacturing aircraft interior parts.
