RADOME FOR ANTENNA AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a high temperature-durable radome for an antenna which is light and resistant to high temperatures and has high strength and low dielectric permittivity, and a manufacturing method thereof. To this end, provided are a method of manufacturing a high temperature-durable radome for an antenna, which includes a molding preparation step of preparing liquid ceramic resin, nonmetal fiber-reinforced fabric which is cut in consideration of the thickness and shape of a product, and a radome mold onto which a mold release agent is applied; a fabric stack step of impregnating the cut nonmetal fiber-reinforced fabric with the ceramic resin and laminating the output onto the radome mold in order; a room temperature hardening step of hardening the product made by laminating the ceramic resin-impregnated nonmetal fiber-reinforced fabric at room temperature for a predefined period of time; a high temperature hardening step of hardening the room temperature-hardened product at high temperatures equal to or higher than 350°C for a predefined period of time; and a machining step of taking the high temperature-hardened product away from the radome mold and processing the product using a machining device according to the final request size; and the high temperature-durable radome for an antenna manufactured by the describe manufacturing method.
