Abstract: This paper introduced the fuselage structure and traditional manufacturing process of unmanned aerial vehicle (UAV) as well as the problems appearing in the processing procedure. Furthermore, this paper also introduced a pressure-pad manufacturing process for the small-sized UAV and a co-curing process for the composite honeycomb sandwich plate with a load beam, which could be applied in the manufacture of the frame-beam honeycomb sandwich structure. Compared to the traditional process, this method can reduce the manufacture cost, improve the surface quality of composite parts and shorten the manufacture cycle of UAV.
