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.
