摘要
Abstract
In order to achieve rapid structural prediction and flexible performance control of electromagnetic functional papers,using poly-m-phenylene isophthalamide as the matrix,this study prepared electromagnetics function papers by adding conductive carbon fibers in the wet papermaking process.By simulating the internal conductive fiber network structure and using commercial finite element analysis software(HFSS)to construct an electromagnetic simulation model,high-precision simulation calculations of electromagnetic parameters were carried out at an electromagnetic wave frequency of 10 GHz.Combined with measured data,the influence of carbon fiber addition amount and length on the dielectric properties and electromagnetic shielding properties of the papers was systematically analyzed,and the application perfor-mance of the simulation model was evaluated.The results showed that the simulation data of the relative dielectric constant of electromagnet-ics function papers were in good agreement with the measured results in terms of numerical magnitude and variation trend.The simulation er-ror rates of the model under different carbon fiber addition amounts(0.5%～2.5%)and lengths(2～9 mm)were lower than 18.5%and 34.4%,respectively.Under the condition of a carbon fiber length of 3 mm,as the carbon fiber addition amount increased from 0.5%to 2.5%,the rela-tive dielectric constant and electromagnetic shielding effectiveness of electromagnetics function papers showed an overall increasing trend.Under the addition amount of 1.0%carbon fiber,as the carbon fiber length increased from 2 mm to 6 mm,the electromagnetic shielding effec-tiveness of electromagnetics function papers showed an upward trend.And the reflection coefficient and absorption coefficient increased si-multaneously,while the transmission coefficient continued to decrease.When the carbon fiber length was 6 mm,the electromagnetic shield-ing effectiveness reached a maximum value of 4.49 dB.关键词
