摘要

摘要: 针对现有飞行器复合材料蒙皮难以兼顾承载性能和吸波性能的问题，利用碳纤维预浸料独特的力电特性构造了碳纤维双极化吸波层合结构（carbon fiber dual-polarized absorbing laminated structure, CFDALS）.通过在玻璃纤维层合结构中引入双向碳纤维阵列结构，赋予层合结构双极化电磁波吸收特性，同时利用碳纤维反射层优异的承载性能来增强结构力学性能.电磁仿真结果表明，该结构对TE极化电磁波在8~18 GHz频带、0°~45°入射角，同时对TM极化电磁波在5~18 GHz频带、0°~60°入射角下平均吸收率均达到90%以上.三点弯曲仿真结果表明，结构在实现双极化电磁吸波的同时，在碳纤维阵列两个排列方向上表现出较高的比弯曲强度、比弯曲刚度.通过在玻璃纤维预浸料中引入双向排列的碳纤维预浸料并进行一体化设计，在结构具备双向优异承载性能的同时实现了双极化电磁吸波性能的显著增强，为飞行器蒙皮隐身承载一体化设计提供了一种新的解决方案.

Abstract: To address the challenge of balancing load-bearing and electromagnetic (EM) wave absorption properties in aircraft composite skin, the outstanding mechanical and electrical characteristics of carbon fiber (CF) prepregs were utilized to construct a carbon fiber dual-polarized absorbing laminated structure (CFDALS). The bidirectional CF arrays were introduced into the glass fiber (GF) laminated structure, to endow the laminated structure with dual-polarized EM wave absorption performances. Additionally, the excellent load-bearing capacity of the CF reflector was used to enhance the mechanical properties. Simulation results indicate that, the CFDALS achieves an average absorptivity over 90% within the 8~18 GHz frequency band at incident angles of 0°~45°, and within the 5~18 GHz band at incident angles of 0°~60° for TE and TM polarized EM waves, respectively. The 3-point bending simulation results show that, the CFDALS exhibits higher specific flexural strengths and stiffnesses along 2 directions of the CF arrays while achieving dual-polarized EM wave absorption. Incorporation of bidirectionally arranged CF prepregs into GF prepregs enhances the dual-polarized EM wave absorption performance and the bidirectional flexural performance of the CFDALS simultaneously. The work provides a novel solution for the EM wave absorbing and load-bearing integrated design for aircraft composite skin applications.
