Abstract

A composite plastic duct structure comprised of an outer layer of fabric material impregnated with a fire-resistant resin material and an inner liner layer of chemically corrosion resistant resin material impregnated with a fabric material. The invention includes a method wherein multiple wrappings of resin impregnated material are wound on a mandrel to form the inner and outer layers.
