Abstract:
1. A method for producing a composite material suitably adapted for use in elevated temperature environments, said method comprising the steps of: providing a phthalonitrile monomer selected from the group consisting of: heating said phthalonitrile monomer to its melt stage; combining said phthalonitrile monomer with a curing agent to form a prepolymer mix; heating the prepolymer mix to a temperature at least greater than the melt temperature of said prepolymer mix; at least one of impregnating and coating a reinforcement material with said prepolymer mix to produce a composite material; and heating said composite material to a temperature of at least greater than the melt temperature of said prepolymer mix for a sufficient time to cure said composite material.
