Analysis of influence of carbon fiber structure arrangement on its radiation characteristics
In order to study the spectral radiation characteristics of carbon fiber
the finite difference time-domain method is used to investigate the radiation characteristics of carbon fiber in different configurations. The results show that the scattering factor of carbon fiber with the same radius in 2D random distribution decreases with the decrease in content of carbon fiber. When the content decreased by 17.12%
the maximum value of the scattering factor is decreased by 35%. Under the 2D random distribution of non-uniform radius carbon fiber
besides of the influence of carbon fiber content on the material’s radiation characteristics
the number of carbon fiber particles with small radius under the same content will increase the scattering factor by 20% in the 2.5—3.5 μm band. Compared with 2D random arrangement
3D random arrangement can significantly enhance the radiation characteristics of carbon fiber.
