Abstract

The invention relates to the technical field of wave absorbing materials, particularly to a carbon fiber / amorphous alloy composite electromagnetic wave absorbing material and a preparation method thereof. The carbon fiber / amorphous alloy composite electromagnetic wave absorbing material is prepared by compounding carbon fiber and Ni-Co-Fe-P amorphous alloy layers. The carbon fiber / amorphous alloycomposite electromagnetic wave absorbing material has electromagnetic loss characteristics effectively integrating resistance loss, dielectric loss and magnetic loss and meanwhile is a high-performance-intelligence electromagnetic wave absorbing material capable of achieving electromagnetic parameter adjustability and high-strength and broadband absorption.

Description

Technical field [0001] The invention relates to the technical field of absorbing materials, in particular to a carbon fiber / amorphous alloy composite electromagnetic wave absorbing material and a preparation method thereof. Background technique [0002] With the continuous development of electronic information, whether in the military or civilian fields, while electromagnetic waves have brought good news to the industry, many problems have also arisen, such as electronic information interference, security information confidentiality, and electromagnetic radiation to people’s health problem. [0003] Carbon fiber is a very good material. The physical properties of carbon fiber have the characteristics of high strength and high modulus. It has stable chemical properties, does not burn, and is not corroded by acid, salt and other solutions. The linear expansion coefficient of carbon fiber is small, and the mechanical properties change little under high temperature; carbon fiber has...
