UAV surface coating, preparation method thereof and UAV

Abstract

A UAV surface coating includes at least a bonding layer, an antioxidant layer, an oxygen-blocking propagation layer and a heat-insulation cooling layer. The coating is fabricated on a surface of a UAV machine body or covers on the surface of the UAV machine body through a composite material matrix. The UAV machine body is made of lightweight material, and the composite material matrix includes a resin-based composite matrix and a ceramic-based composite matrix. Wherein, a thickness of the bonding layer is from 20 μm to 200 μm, a thickness of the oxygen-blocking propagation layer is from 20 μm to 200 μm, and a thickness of the heat-insulation cooling layer is from 80 μm to 1000 μm.
