Abstract: Invention relates to a radome casing and method for its manufacturing. The radome casing comprises walls (6, 11) of composite material which includes reinforcement fibers (8) and matrix resin (19) binding the fibers together. The walls include aradiation transmission window (11) through which the radiation of a radomeantenna passes when the radome antenna (2) is mounted inside the radome casing (1). The amount of fibers in the radiation transmission window (11) is reduced to be less than 40-5% of the amount of fibers elsewhere in the casing walls (6). The reduction of reinforcement fibers in the radiation transmission window (11) reduces attenuation of the high frequency radiation.

Abstract: A method for manufacturing a flexible composite belt or cable. In the meth- od, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic pro- files are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.
