Abstract

A method of producing a structural component (12) from a primary wall structure (14) which defines a plurality of juxtaposed primary cells (15) which extend between and which are open to the front face and the rear face of the component (12) and a secondary wall structure (16) within the primary wall structure (14) wnich divides each primary cell (15) into two or more subcells (151, 152) comprises first forming the primary wall structure (14) and then forming the secondary wall structure (16) within the primary wall structure (14) by bringing the primary wall structure (14) into a condition in which it lies within a body of liquid, the surface of which provides or is provided with a photosensitive layer and in which the photosensitive layer is at a predetermined level in each primary cell (15) and exposing the photosensitive layer to radiation source to bring the photosensitive layer to a consolidated state within the primary wall structure (14) to form the secondary wall structure (16). Where the component (12) is a noise attenuation panel, the secondary wall structure (16) may be so formed as to provide for the required sound absorption properties while providing substantially no support for structural loads. <IMAGE>
