1、 Characteristics and advantages of carbon fiber structured absorbing materials

Carbon fiber structure absorbing material, as the name suggests, is a composite material with absorbing function prepared by special processes using carbon fiber as the matrix. This material not only inherits the excellent characteristics of carbon fiber such as high strength, high modulus, and lightweight, but also has excellent absorption performance. Under the action of electromagnetic waves, carbon fiber structured absorbing materials can effectively absorb and convert electromagnetic wave energy, thereby achieving the goal of reducing electromagnetic radiation and protecting the safety of electronic devices.

In addition, carbon fiber structured absorbing materials also have good designability and processability. By adjusting the arrangement and content of carbon fibers, as well as the formula of composite materials, precise control of absorption performance can be achieved. This enables carbon fiber structured absorbing materials to be widely used in aerospace, communication electronics, military equipment and other fields, providing strong support for the development of modern technology.

2、 Exploration of Preparation Technology for Absorbing Carbon Fiber

The preparation of absorbing carbon fibers is a key step in the development of carbon fiber structured absorbing materials. At present, the preparation technologies of microwave absorbing carbon fibers mainly include chemical vapor deposition, sol gel method, electrospinning method, etc.

Chemical vapor deposition is a method of improving the absorption performance of carbon fibers by depositing absorbing substances such as metal oxides, carbon nanotubes, etc. on their surface. The absorbing carbon fibers prepared by this method have the advantages of stable absorbing performance and easy control, but the preparation process is relatively complex and the cost is high.

The sol gel principle is to coat the precursor solution of the microwave absorbing material on the surface of the carbon fiber, through gel, heat treatment and other steps, so that the microwave absorbing material can form a dense film on the surface of the carbon fiber. The cost of preparing absorbing carbon fibers using this method is relatively low, but the absorbing performance may be affected by the preparation conditions.

The electrospinning method is to use electric field force to stretch polymer solutions containing absorbing materials into nanofibers, and then composite the nanofibers with carbon fibers. This method can prepare nano carbon fiber composite materials with excellent absorbing properties, but precise control of parameters such as electric field strength and solution concentration is required during the preparation process.
