Abstract

The invention belongs to the technical field of chemistry, material science and surface treatment, and particularly relates to a preparation method for an anti-icing composite material. The preparation method comprises the following steps of: (1) constructing a microstructure of a micro bulge on a metal plate surface; (2) constructing a micro-nano composite structure on the microstructure throughan inorganic particle with a nano structure; (3) compounding the micro-nano composite structure to the surface of composite material substrate through a template process to obtain a preliminary composite material; (4) coating a low-surface-energy substance layer on the surface with the micro-nano composite structure of the preliminary composite material; and (5) refining the micro-nano composite structure. The composite material obtained through the method has comprehensive performances such as a more refined micro-nano structure, high surface structural strength and good surface chemical stability; and a preparation process is simple, is economical and environmentally friendly, and is beneficial for large-scale production and application.

Description

technical field

[0001] The invention belongs to the technical fields of chemistry, material science and surface treatment, and in particular relates to a preparation method of an anti-icing composite material. Background technique

[0002] When an aircraft flies at a subsonic speed less than a certain critical Mach number under icing weather conditions, the windward surfaces of some components will freeze due to the impact and accumulation of water droplets in the atmosphere. A large number of accidents and studies have shown that even a small amount of ice accumulation on key parts of the aircraft will lead to a decrease in the lift of the aircraft and an increase in flight resistance, which will lead to deterioration of the aerodynamic qualities of the aircraft such as maneuverability and stability. Especially when the aero-engine is under a certain temperature and humidity on the ground and in the air, the air intake fairing and support plate are prone to icing. The icin...
