Abstract

Abstract: In wartime, the skin of aircraft will be damaged by bullet attack, which will affect the normal flight of helicopter. In order to solve this problem, a new quick repair technology of skin based on adhesive and fiber prepreg was studied. Firstly, the repair scheme and process of this process are introduced. Secondly, on the basis of the above research, the influence of repairing method and grinding method on the strength of repaired skin was studied by combining simulation and experiment. Finally, the results of the above research were verified by experiment, and the strength of repaired skin by this process method could reach more than 98% of the strength of skin mother plate. Its repair time is reduced to 2/3 of the traditional composite repair process, and its repair weight is 1/3 of the traditional process.

Key words: skin damage, quick repair, composite materials, process
