A plurality of elongate segments, joined along their abutting side edges, form a variable geometry exhaust nozzle for a turbojet engine afterburner. The segments may be planar or slightly curved. Each segment is devoid of metal on its 'hot' side and has at least one elongate edge portion bent in not more than about 90.degree. towards the 'cold' side of the segment at least along the longitudinal side facing the adjacent panel. The panels are mutually joined to form said segment under the intermediation of metal elements, preferably of U-shape, for gripping adjacent pairs of bent portions of the respective panel pairs, at least some of said metal elements and the respective edge portions thereof having holes for accommodating hinge shafts and/or actuation means such that on each segment a continuous ceramic surface, entirely free of metal, faces the hot exhaust gas flow of the engine.
