Problems solved by technology
However, this method of pulling away from the mold by mechanical force can easily damage the metal layer that has been transferred to the inner wall of the waveguide cavity
Therefore, the above methods cannot meet the design requirements regardless of the structural and functional aspects of the antenna.

The invention discloses a drip irrigation dissolution metal transfer core mold and metal plating layer transfer method, and is suitable for the technical field of radar wave guide antennas. A double-hole aluminum core mold surface metallic transfer technology is formed through a pultrusion process; an aluminum core mold is quickly dissolved by using strong base solution through a drip irrigation mode; under the condition of not corroding carbon fiber wave guide, metal copper electroplated on the surface of the aluminum core mold is transferred into a wave guide inner cavity; and meanwhile, the damage to a metal layer in the wave guide inner cavity by a demolding procedure is removed, so that a resin base carbon fiber wave guide antenna for satisfying the electric performance index is obtained. The core mold adopts a double-hole structure; the strong base corrosion liquid can quickly enter holes in the core mold to conveniently and quickly dissolve the aluminum core mold; and when the core mold is quickly dissolved, the strong base corrosion liquid cannot pollute the carbon fiber wave guide antenna.
Description
technical field [0001] The invention relates to the technical field of radar waveguide antennas, in particular to a method for transferring mandrels and metal coatings of drip irrigation and dissolution type metal transfer. Background technique [0002] For radar antennas, waveguide antennas are one of the most important forms. Since the waveguide antenna is based on the spaceborne platform, there are strict requirements on the weight of the antenna, so the waveguide is made of resin-based carbon fiber composite material, and the surface of the inner cavity is metallized to achieve the electrical performance index of the antenna . [0003] Due to the small cross-sectional area and long length of the inner cavity of the waveguide antenna, it is difficult to form a dense and uniform metal layer on the surface of the inner cavity of the waveguide by the usual electroplating method. In addition, since the material of the waveguide is a resin-based carbon fiber composite materi...
