Abstract

The invention relates to a forming method of an anti-icing array structure on the surface of a thermosetting resin-based composite material. An anti-icing array on the surface of the thermosetting resin-based composite material is prepared by designing an anodic aluminum oxide template structure and adjusting forming parameters of the composite material. The forming method has the beneficial effects that the forming method of the anti-icing array structure on the surface of the thermosetting resin-based composite material is simple in manufacturing process, the manufactured composite materialis complete in surface micro-nano structure, stable in size and high in structural consistency, the super-hydrophobic characteristic is achieved on liquid water, the super-cooled liquid drop icing time can be remarkably prolonged, and supercooled liquid drops have enough time to be separated from the surface; the extremely low ice adhesion strength is achieved, and an ice coating can fall off fromthe surface under the action of natural wind or gravity; and the anti-icing array structure can be used for machine outer surfaces such as aircrafts and wind driven generator blades which are exposedin an extreme environment, and important significance on development of ice prevention and removal technologies of equipment such as wind driven generators, novel high-speed railway motor train unitsand airplanes, in particular to passive ice prevention and removal technologies is achieved.

Description

technical field [0001] The invention belongs to the field of composite material surface processing technology and surface modification technology, and in particular relates to a method for forming an anti-icing array structure on the surface of a thermosetting resin-based composite material. Background technique [0002] Thermosetting resin-based composite materials generally refer to continuous fiber / short fiber reinforced thermosetting resin-based composite materials, which have the characteristics of light weight, high strength and high stiffness, and have been widely used in the fields of national defense and people's livelihood. For example, the United States uses glass fiber reinforced epoxy resin composite materials to make rocket engine casings, high-pressure containers for fuel, and helicopter rotor blades. The domestic C919 aircraft skin uses a large number of epoxy resin composite laminates. [0003] Icing on the surface of aircraft such as high-altitude drones a...
