Embodiment Construction

[0017] The metallization process of epoxy FRP antenna with honeycomb sandwich structure refers to the process of obtaining a certain thickness of metal film layer through modification treatment on the surface of epoxy FRP matrix with honeycomb sandwich structure.

[0018] The process route of the present invention can be summarized as: antenna surface sealing modification treatment → antenna pre-treatment (including degreasing roughening and modified sealing material roughening) → antenna metallization treatment (including chemical metal film formation and electroplating thickening) → metal The post-treatment of the three defenses of the film layer is such a sequential process.

[0019] 1. Antenna surface sealing modification treatment

[0020] The sealing modification treatment of the antenna surface refers to: 1) firstly wipe the surface of the honeycomb sandwich structure epoxy glass fiber reinforced plastic substrate to be metallized with alcohol, and then preheat it at 45...

Abstract

The invention discloses a metallization process for a honeycomb epoxy glass fiber reinforced plastic antenna. The metallization process comprises a sequential technological process of antenna surface sealed modification treatment and antenna pre-treatment, oil-removing coarsening and modified sealed material coarsening and antenna metallization, and chemical formation of a metal film, electroplating and thickening and three-proofing post-treatment of a metal film layer. After being metalized, the honeycomb interlayer structure epoxy glass fiber reinforced plastic antenna has a metal appearance; surface conduction, heat conduction, magnetism conduction, solvent etching resistance, good conduction resistance and various electrical performance indexes can meet antenna design requirements. Compared with a conventional glass fiber reinforced plastic non-metal material metallization process, the antenna sealed modification treatment is simple in technological process and does not need special technological equipment including plasmas or laser induction and the like; the metallization process has high practicability and reliability and is convenient for use properties of promoting production and machining.

Description

technical field [0001] The invention relates to an epoxy fiberglass antenna, in particular to a metallization process for an epoxy fiberglass antenna with a honeycomb sandwich structure. Background technique [0002] Epoxy FRP is a composite material that has been developed rapidly for more than 50 years. It has superior performance and price ratio and is easy to be molded into complex product shapes. High environmental resistance, especially its high performance and low density make it have greater advantages than metal in many application fields. The honeycomb core material for the honeycomb epoxy fiberglass sandwich structure can be made of various materials, such as thermoplastic honeycomb, aluminum honeycomb, paper honeycomb, etc. [0003] An antenna is a metal device that radiates into space and receives electromagnetic waves from space in a radio transceiver system. However, the honeycomb sandwich structure epoxy glass fiber reinforced plastic material is a poor con...
