ABSTRACT:
A process for the manufacture of a surface element in the form of a lamellar mat or sheet which can be used for the absorption of electromagnetic waves, in particularly radar waves. The surface element has a plurality of bands of mineral wool separated by bands of an electrically-conducting material and is manufactured on an industrial scale by stacking several mineral wool strips, sheets, or mats with intermediate layers of the electrically-conducting strips, sheets or mats into a pile. From this pile are then cut out pads composed of different bands which are laid out in such way that their cut faces become the large surface areas of the surface element. Then, each of the surface elements is clad on at least one face with a backing strip, for example of meshed aluminum foil, the main orientation of the fibers of the mineral wool being perpendicular to the backing strip.
