The microwave absorbing property is affected significantly by the distribution of the triangle cross-section carbon fibers in the composite materials. In this study, the distribution of the triangle cross-section carbon fibers in the triangle cross-section carbon fiber reinforced plastics is investigated by experimental and theoretical simulations. In order to study the angle arrangement and the homogeneity of the carbon fibers in the composite materials, the cross-section morphology of the samples is observed by the SEM. And a process based on the Monte Carlo Method is established to simulate the distribution of the triangle cross-section carbon fibers in the triangle cross-section carbon fibers reinforced plastics. The simulation results agree with the experimental data, which indicates that the triangle cross-section carbon fibers are arranged in a random in angles and approximately homogeneous distribution. This simulation method could be used to simulate the cross-section morphology of the triangle cross-section carbon fibers reinforced plastics with arbitrary fiber contents., authors=LIU Xin^1,2, WU Zhanjun¹, WANG Rongguo², LIU Wenbo², YAN Jia¹, authorsList=LIU Xin;WU Zhanjun;WANG Rongguo;LIU Wenbo;YAN Jia, authorCompany=1.

articleAbstract=三角形截面碳纤维在复合材料内部的排布结构像微波暗室一样,能够对入射的电磁波进行多次反射,从而衰减电磁波,使三角形截面碳纤维复合材料具有吸波性能,因此,研究三角形截面碳纤维在复合材料中的排布规律对研究其吸波机理非常重要.采用实验和模拟的方法对三角形截面碳纤维在复合材料中的排布规律进行了分析.首先,通过扫描电子显微镜(SEM)观察了多组三角形截面碳纤维复合材料试样的截面微观形貌,分析了三角形碳纤维在复合材料中的排布角度及均匀性;其次,为进一步研究三角形截面碳纤维复合材料的吸波机理,根据蒙特卡洛原理,通过Matlab软件对三角形截面碳纤维在复合材料中的排布情况进行了模拟.实验及数值模拟结果吻合较好,均表明三角形截面碳纤维在复合材料中的排布是以各种排布角度随机排布的,而三角形碳纤维分布是比较均匀的,没有明显的密布区域和稀疏区域,该模拟方法可以用于模拟不同含量的三角形截面碳纤维在复合材料中的排布规律.,
