This invention relates to a method of manufacturing laminated material. Particularly to laminated materials for use in the construction of flame tubes of gas turbine engines. The laminated material is manufactured from three sheets, a central sheet, a first sheet, and a second sheet. The central sheet is perforated with an arrangement of equi-spaced apertures. The central sheet with apertures is then secured to the first sheet. A number of channels are machined through the central sheet to leave the first sheet and an arrangement of equi-spaced lands secured thereto. The first sheet is perforated with an arrangement of equi-spaced apertures to form air entry holes. The second sheet is then secured to the assembly to form a laminated material comprising a first sheet with apertures and second sheet separated by an arrangement of equi-spaced lands machined from central sheet.
