Calculation Methods of Reflectance for Anisotropic Composite Laminates Reinforced With Magnetic Coating Carbon Fibers

对磁性涂层碳纤维各向异性铺层板反射率的计算是研究其结构吸波材料性能的基础。本文基于磁性涂层碳纤维单向板的电磁特性分析,研究了电磁波在磁性涂层碳纤维复合材料板中的传输特性。首先推导了单层各向异性复合材料板中的传播常数和波阻抗,在此基础上用传输矩阵法进一步推导了适用于带有磁性涂层碳纤维复合材料铺层板的反射特性。利用此计算方法求解了各向异性复合材料铺层板在不同极化入射电场、材料板不同铺层层数、方向、厚度下的反射特性。最终根据以上算法,开发出各向异性复合材料铺层板结构吸波材料反射率的优化设计软件。

To calculate reflectance of anisotropic composite laminates reinforced with magnetic coating carbon fibers, is the basis of the study on absorbing properties of the structural absorbing materials. Propagation constant and wave impedance of electromagnetic wave in unidirectional anisotropic composite laminates is derived, and reflectance performance of multidirectional anisotropic composite laminates is then derived using transfer matrix method. According to the above derived methods, a kind of reflectance optimization software is developed for multidirectional anisotropic composite laminates with variable parameters such as directions, frequencies, laminate layers, thickness and etc.
