Abstract
A perforate laminated material suitable for use in the manufacture of combustion chambers for gas turbine engines comprises two sheets bonded together, each sheet having a plurality of perforations, the laminated material being formed with internal channels which interconnect the perforations in the abutting sheets, the contact area between the two sheets being in the range 18% to 60% of the surface area of one side of one of the sheets and the ratio between the number of perforations per unit area in the sheets being in the range 2:1 to 10:1 in use the sheet having the larger number of perforations being adjacent a relatively hot gas stream.
