Description

technical field [0001] The invention relates to a manufacturing system and method of a complex-structured wave-absorbing material, in particular to a manufacturing system and method for three-dimensional forming of a wave-absorbing material. Background technique [0002] With the application of electromagnetic wave technology and the development of communication products, problems such as electromagnetic scattering, electromagnetic radiation and electromagnetic compatibility are becoming more and more obvious. The application of wave-absorbing materials provides new ideas for solving such problems. Absorbing materials can usually be divided into two types: structural type and coating type. Among them, the coating-type absorbing materials are mainly prepared by spraying, the structure is simple, the manufacturing precision is poor, and the internal structure is difficult to design and adjust; Less involved. At present, microwave-absorbing materials are faced with high-perfo...

AI Technical Summary

Problems solved by technology

Conventional microwave-absorbing materials will restrict each other in thickness, density, absorption rate, and microwave-absorbing frequency band. In terms of microstructure, the choice of microwave-absorbing micropowder is the main choice, and the controllable manufacturing of microstructure is rarely involved. In order to achieve low-thickness Excellent broadband absorbing performance, the addition of absorbing particles is high, and the density of absorbing materials is high, which will easily lead to poor physical and chemical properties

In terms of civilian use, with the improvement of people's awareness of the hazards of electromagnetic radiation, a series of civil microwave-absorbing materials have appeared, such as mobile phone radiation-proof patches, microwave-absorbing pyramids, etc., but due to the lack of manufacturing technology, the product structure is relatively simple, poor designability
