Microwave absorption properties of MWCNT/GF/EP composites based on Giannakoopulou model
This study investigates the electromagnetic wave absorption performance of MWCNT/GF/EP composite ma-terials in the X-band,incorporating varying mass fractions of MWCNT.Utilizing the Giannakoopulou model and intro-ducing a transparent layer,the study examines the influence of the ratio and distribution status between the absorption layer and the transparent layer on the overall absorption performance of the material.The results indicate that for the composite material with 2％mass fraction of MWCNT,at a thickness of 3.0 mm,the peak reflection loss is-44.5 dB,with an effective absorption bandwidth of 3.3 GHz(8.2-11.5 GHz).Through the rational design of the absorption layer and transparent layer in terms of their ratio and distribution status,materials with different effective absorption band-widths and absorption loss peak values are obtained.The highest peak reflection loss reaches-62.1 dB,with an effec-tive absorption bandwidth of 3.1 GHz.
