摘要
Abstract
Fiber absorbent has been applied in the field of stealth and electromagnetic compatibility due to its advantages of broadband absorption,light weight,and corrosion resistance.Analyzing the research progress in this field is of great significance for the design of broadband and efficient absorbing materials.This paper discusses the action mechanism,numerical simulation method,factors affecting electrical properties,and preparation technology of fiber absorbents.Both the dielectric loss mechanism based on dielectric constant and the ohmic loss mechanism based on impedance are used to explain the microwave absorption mechanism of this kind of material,which is verified by theory and experiment.Through the full-wave theoretical simulation,the electrical properties of complex structure and high concentration fiber absorbers can be better analyzed.The parameters such as fiber type,content,and length have a great impact on their electrical properties,which are widely used in the preparation process.It is particularly important to select appropriate ultrasonic dispersion parameters and dispersants.In the future,further research can focus on the distribution of current and electric field distribution in fiber absorbers to clarify the interaction and coupling mechanisms between fibers.Under the same conditions(such as fiber content and length),the effects of fiber type and electrical conductivity on electrical performance should be compared,along with the differences between carbon fibers of different specifications.These efforts aim to achieve optimal performance in terms of broadband response,high efficiency,and thickness.This review holds great significance for the design of broadband and high-efficiency microwave-absorbing materials.关键词
