▎ 摘　　要

NOVELTY - The method involves obtaining a dielectric constant of a honeycomb wall of honeycomb core material (1) and dielectrical constant epsilon i of a CNTs/CB/RGO/PU impregnation layer (2). A polarization correction factor and a structure correction factor are added to a BG formula. An equivalent homogeneous BG model is established to obtain a homogeneous wave-absorbing model (II). A graphene/non-woven fabric composite material (3) is obtained to obtain the dielectrics of the honeycomb. The honeycomb is filled with honeycomb unit filler and an equivalent polymers (MG) model. A volume ratio of the BG model in the honey comb is obtained. USE - Method for constructing equivalent electromagnetic parameter calculation model of non-woven fabric/honeycomb wave absorbing structure e.g. graphene/nonwoven fabrics composite material. ADVANTAGE - The consistency of the calculation value of the equivalent electromagnetic parameter of the honeycomb structure and the actual value is improved. The influence of polarization anisotropy of carbon-based absorbent in the matrix, data honeycomb unique hexagonal structure of the gain of the dielectric performance is solved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the non-woven fabric/honeycomb wave absorbing structure. 1Honeycomb core material 2Rgo/pu impregnation layer 3Graphene/non-woven fabric composite material
