摘要: 为了应对飞机高空飞行时防除冰的需求,本文提出采用激光诱导石墨烯技术制备具有电加热功能的复合材料结构的方法。根据机翼前缘结冰特点,设计了中间密集、两边稀疏的波浪形加热线形式,利用激光诱导石墨烯技术快捷、高效、成本低的优点,通过二氧化碳激光器在聚酰亚胺纸表面诱导出石墨烯加热线图案,并将其与复合材料预浸料共固化形成层合结构。进行了一系列电加热实验,测试和分析在一定电流作用下结构表面竖直与水平方向的温度分布规律以及对一定厚度和质量冰层的电加热融化情况,验证了所提出和制备的复合材料电加热结构的可行性和有效性。

Abstract: In order to meet the requirement of anti/deicing for aircrafts flying at high altitude, a method of fabricating composite structure with electrical heating function with laser-induced graphene technology is proposed in this paper. Based on the icing characteristics of the leading edge of the wing, a wavy pattern with dense heating lines in the middle and sparse heating lines in the sides is designed. Utilizing the advantages of laser-induced graphene technology, i.e., fast, high efficiency and low cost, the graphene heating line pattern is induced on the surface of polyimide paper by carbon dioxide laser, and then is co-cured with composite prepregs to form a laminated structure. A series of electrical heating tests are carried out to analyze the temperature distribution rules along the vertical and horizontal directions on the surface of the structure and melting situation for ices with certain thickness and mass, under certain currents applied. The results have demonstrated the feasibility and effectiveness of the proposed and fabricated composite structure with electrical heating function.

Key words: laser-induced graphene, composite structure, electrical heating function, electrical heating tests
