The composite duct system includes a first, duct portion; a second, duct foam portion; and, a third duct portion. The first duct portion has a first surface for permitting a flowable medium to be conveyed adjacent thereto, and a second surface. The first duct portion is formed with a first fiber reinforced resin system. The second duct foam portion has a first surface bonded to the second surface of the first duct portion. The foam portion is formed of fire retarding material derived from a resin system. The third duct portion has a first surface bonded ...


[ What is claimed and desired to be secured by Letters Patent of the United States is:] [1.] A composite system for use in forming a duct system comprising:a) a first duct portion having a first surface for permitting a flowable medium to be conveyed adjacent thereto and a second surface, said first duct portion being formed of a first fiber reinforced resin system;b) a second duct foam portion having a first surface bonded to said second surface of said first duct portion, said foam portion being formed of fire retarding material derived from a resin sy...
