ABSTRACT:
A method of making integrally a composite material comprises a first fiber cloth, which is impregnated with a foaming agent before being joined with a second fiber cloth. The combination of the first fiber cloth and the second fiber cloth is treated in a heating device in which the composite material is formed integrally of the first fiber cloth, the second fiber cloth and foam layers formed by the foaming agent of the first fiber cloth and some of the foaming agent that have permeated into the second fiber cloth from the first fiber cloth. The composite material is provided with an excellent air permeability and a heat insulating capability.
