Abstract

The present invention relates to a composite waveguide tube with a pre-formed thin metal sheet lining and a method for producing the same. The method includes: assembling a metal mold core into an internal-hollowed mold for a component; wrapping a pre-formed thin metal sheet lining on the outside of the internal-hollowed mold; wrapping a fibrous polymer composite material on the outside of the thin metal sheet lining; mounting the assembly in the contour mold of the component; applying pressure and heat to the mold to form a composite component; and applying a highly conductive metal layer on the surface of the component in order to endow the component with a good waveguide effect. The invented method can produce an integral composite waveguide tube with a pre-formed thin metal sheet lining having a high strength, light weight, a good waveguide effect, and a reduced production cost.

The appearance is usually a rectangular screw pin, which is shaped as a high-conductor. The wave material is made in sections, and then the wave tube structure is used. "Tian Wu's Guide to Echo Waveguide" "The technical problem that k wants to solve) The quasi-original traditional waveguide tube is made of high-waveguide metal because the waveguide tube has a perch, and two. Material production, however, the conductive material is often heavy, the welding place is easy to corrode and the strength is low, and it is not wave and economic benefits.

V. Explanation of the invention (2) In view of this, the inventor has invented a complex material waveguide lined with a two-U material plate and its system based on the concept of long research and thorough understanding. Its metal thickness is thin. Then, the metal sheet lining is coated on the outside of the inner hole mold of the metal si part, and then the fiber polymer composite material is coated on the metal sheet lining, and then it is placed on the inside of the external mold. After heating and forming, after dismantling the mold, an integrated two-component waveguide can be obtained. From the above description (contrast with the effectiveness of the first-gang technology) It is learned from the above description that the present invention and its manufacturing method can indeed achieve several advantages: The following "1. Integrated molding, good structural strength: the present invention uses combined gold The composite waveguide, which is directly formed by the core and the outer mold, directly integrates the high-wave-guide metal sheet lining with the composite / waveguide. It can overcome the problems caused by the processing of the parts and then joining them. In order to improve the structural strength = 2, 2. With a high guided wave effect: Because the thickness of the metal sheet of the present invention is relatively uniform, it can overcome the surface defects caused by pores in the composite material, and the angle problems, and can be seen. It is necessary to apply a highly conductive metal chain layer, which has a good wave-guiding effect. X㈢ ′ makes it less 3, and the process is simplified: Since the present invention uses a combined metal mold core and t mold to directly form a composite waveguide, it can Eliminates the need for " processing and joining processes in traditional waveguides, to simplify the process and to be extremely economical and practical:
