Patent

CA 2503598

A multi-layer duct for air distribution in air conditioning systems, in particular, yet not exclusively, for aircraft vehicles, is made through a process providing an overlapping of layers of advanced composite materials, comprising: one substantially fluid tight polymer film, defining the inner wall of the duct; at least one stiffening structural layer, formed by a sheet of structural fibres preimpregnated in a polymer matrix of thermosetting resin, enveloping said polymer film; and one or more optional additional functional layers of structural and/or functional fibres, preimpregnated in a polymer matrix of thermosetting resin.
