Embodiment Construction

[0026] Referring now to the accompanying drawings, specific embodiments of the present invention will be described in detail. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to realize the present invention on the basis of the preferred embodiments, and the other ways also fall within the scope of the present invention.

[0027] The invention provides a composite material for an aircraft and a method of manufacturing the composite material. figure 1 A composite material 100 according to a preferred embodiment of the invention is shown.

[0028] The composite material 100 mainly plays the role of anti-icing and de-icing, and includes a base layer and at least two electric heating layers located on the upper side of the base layer.

[0029] Specifically, refer to figure 1 , it can be seen that the base layer includes the main structural layer 1 and the first insulating layer 21 and the second ...

Abstract

The present invention relates to a composite material and a method for its manufacture. The composite material includes: a matrix layer and at least two electric heating layers. Each electric heating layer is configured to be able to conduct electricity and generate heat, wherein at least two electric heating layers are made of metal materials with different melting points, and each electric heating layer is on the upper side of the base layer from the base layer in order of increasing melting point Layered arrangement. According to the present invention, the electric heating layer in contact with the base layer of the composite material has a relatively low melting point, is easy to bond with the base layer and is not easy to damage the electric heating layer when spraying the electric heating layer; and the electric heating layer with a high melting point does not contact the base The layers are in contact, so the high melting point electric heating layer does not directly contact the base layer, which will not damage the base layer and can achieve a better heat generation effect.

Description

technical field [0001] The invention relates to the field of aircraft maintenance and manufacture, in particular to a composite material used for aircraft components and a method for manufacturing the same. Background technique [0002] As more and more composite materials are used in modern civil aircraft structures, and with the application of aircraft multi-electric technology and the development of electric anti-icing technology, aircraft electric anti-icing and deicing has become the development trend in the field of anti-icing in the future. [0003] From the perspective of production and manufacturing, the technology of processing anti-icing and deicing electric heating film in the form of spraying has gradually developed and matured. The existing technology can realize spraying alloy electric heating film coating on the surface of composite material substrate. The key step of the functional unit of the composite material formed by spraying is to spray the metal on th...
