Abstract

A method for manufacturing a satellite antenna metal mesh. The steps are as follows: (1) Prepare materials for manufacturing the metal mesh, gold with a mass percentage of ≥99.5 and molybdenum wire with a mass percentage of ≥99.9; (2) Use a composite gold coating method based on thermophysics to coat the molybdenum The surface of the wire is coated with gold to obtain gold-coated molybdenum wire, and the diameter of the gold-coated molybdenum wire is 15-30 μm; (3) 2-7 gold-coated molybdenum wire single wires are plied together to obtain metal strands; (4) Step (3) ), the combined metal strands are woven into a rhombus mesh structure.

Description

Technical field The invention relates to a method for manufacturing a satellite antenna metal mesh, which is suitable for the needs of mesh-like deployable space antennas in different frequency bands and different uses. Background technique Mesh deployable space large-scale antenna is a key equipment for spacecraft such as high-orbit electronic reconnaissance satellites, high-orbit mobile communication satellites, and deep space exploration satellites. These mesh-like deployable antennas fold up during launch and unfold into working condition after entering orbit. Depending on the needs, the diameter of these antennas ranges from several meters to tens of meters, or even hundreds of meters. Large deployable antennas include mesh deployable antennas, solid surface deployable antennas, inflatable antennas and other forms. Solid-surface deployable antennas have not been put into practical use due to their complex mechanisms and low deployment reliability. Inflatable antennas...
