[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. Carbon fiber is mainly composed of carbon elements and has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. The main use of carbon fiber is to manufacture high-tech equipment such as aerospace, as well as advanced composite materials.

[0003] Currently, during flight, aircraft are at high altitude and low temperature, which makes it easy for the wings to ice up. Since the wings are close to the engine group, the engine group will generate heat during operation, so the wings generally do not have ice problems. However, many aircraft now do not have tail engines, so the tail part is prone to ice problems, which makes it impossible to adjust the angle of the tail for flow reversal, posing a huge safety hazard. Summary of the invention

[0021] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1

[0023] See also Figure 1-3 The present embodiment provides a carbon fiber composite material plate with a deicing structure, including a carbon fiber base plate 1, a carbon fiber cover 2 and a heating plate 3. The carbon fiber base plate 1 and the carbon fiber cover 2 are provided with a protective layer 4 on the opposite sides. The carbon fiber base plate 1 and the carbon fiber cover 2 are split disassembly and assembly structures, which can be convenient for manual maintenance and replacement during subsequent use. The inner groove wall of the carbon fiber base plate 1 is buckled and connected with two connecting platforms 5. The connecting platform 5 can be installed on the auxiliary heating plate 3, and it is also a structure for heating and powering on. The connecting platform 5 and the heating plate 3 can also be disassembled and assembled, and the heating plate 3 is assembled in multiple modular positions, so that a single or multiple heating When a problem occurs with the hot plate 3, the undamaged heating plate can also perform normal heating and de-icing, ensuring the stability and safety of the de-icing structure. Both ends of the heating plate 3 are fixedly connected with connecting blocks 6, and connecting grooves 8 are provided on opposite sides of the two connecting platforms 5. The connecting blocks 6 are engaged with the connecting grooves 8, and the heating plate 3 is assembled with the connecting platform 5 by engaging and snapping the connecting blocks 6 at both ends with the connecting grooves 8, making the disassembly and assembly of the heating plate 3 more convenient and efficient. A heating tube 7 is provided in the inner groove of the heating plate 3. The use of a traditional heating tube 7 and a heat-conducting structure makes the de-icing work of the carbon fiber composite material plate safer and more stable, reduces the occurrence of failures, and ensures the safety of the aircraft flight.

[0024] When the tail wing of the aircraft is frosted and frozen due to the low temperature and the liquid in the air during flight, the heating tube 7 inside the heating plate 3 is turned on for heating, and then the graphene heat conducting plates 11 on the upper and lower sides of the heating plate 3 are used for efficient heat conduction, and the heat is conducted to the protective layer 4 in cooperation with the carbon fiber bottom plate 1 and the carbon fiber cover 2 with good thermal conductivity, thereby achieving the de-icing effect on the surface of the protective layer 4. During daily inspection or maintenance, the carbon fiber cover 2 is opened, and then the heating plate 3 can be pulled upward from the connecting platform 5. At this time, the connecting block 6 is separated from the connecting groove 8, and the disassembly is completed. The split modular heating plate 3 can effectively ensure that the de-icing structure will not be damaged and cannot be used, thereby ensuring that de-icing can always be performed and ensuring the flight safety of the aircraft.

[0025] In the prior art, the tail of an aircraft is more prone to surface icing than the side wings where the engines are installed. When ice forms on the tail, the spoiler cannot adjust its angle, so that the aircraft cannot turn normally, posing a certain safety hazard.

[0026] Embodiment 2

[0027] See also Figure 3-4 , further improvements were made on the basis of Example 1:

[0028] A power-on slot 9 is provided at the bottom of the connecting slot 8, and a power-on column 10 is engaged and connected with the power-on slot 9. The power-on column 10 is arranged on the bottom outer wall at a relative position of the connecting block 6. The power-on column 10 and the power-on slot 9 are plugged and connected to supply power, so that the heating plate 3 is more efficient and convenient when being installed and disassembled with the connecting platform 5. Heat-conducting plates 11 are embedded in the upper and lower surfaces of the heating plate 3. The heat-conducting plates 11 are made of graphene thermal conductive material with high-strength thermal conductivity. Graphene has very good thermal conductivity. The thermal conductivity of pure and defect-free single-layer graphene is as high as 5300W / mK, which is the carbon material with the highest thermal conductivity. When the heating tube 7 in the heating plate 3 is heated, the high temperature can be quickly and efficiently transferred to the outer layer for deicing through the heat-conducting plate 11. The high thermal conductivity efficiency can also prevent the problem of excessive heating of the internal temperature of the carbon fiber composite material plate, thereby ensuring the safety of use.

[0029] Embodiment 3

[0030] See also Figure 1 , further improvements were made on the basis of Example 1:

[0031] An insulating filling layer 12 is provided at the outer side of the connecting platform 5, and the insulating filling layer 12 is fixedly connected to the relative position of the bottom of the carbon fiber cover 2. An insulating pressure plate 13 is provided above the heating plate 3 and the connecting groove 8, and the insulating pressure plate 13 is fixedly provided at the relative position of the carbon fiber cover 2. The insulating filling layer 12 can insulate and fill the gap in the inner groove of the carbon fiber bottom plate 1 to ensure the overall strength of the plate. Then, the insulating pressure plate 13 can not only provide insulation safety, but also press the heating plate 3 downward to limit it, thereby ensuring that the heating A plate 3 is more stable after the installation is completed.

[0032] Embodiment 4

[0033] See also Figure 5 , further improvements were made on the basis of Example 1:

[0034] A sealing plate 15 is fixedly connected to one side of the bottom of the carbon fiber cover 2, and a sealing groove 14 is provided at the top of the carbon fiber bottom plate 1 relative to the sealing plate 15. The sealing plate 15 is meshed and plugged with the sealing groove 14, which can provide internal dust and water proofing effects for the detachable carbon fiber plate, ensure the stable and safe use of the internal heating element structure, and through the sealing structure, the high temperature generated inside can be better and evenly dissipated, so as to achieve a more efficient heat conduction and deicing effect. A fixing groove 17 is provided at the edge side wall of the carbon fiber cover 2, and a fixing ear 16 is fixedly connected to the top edge of the carbon fiber bottom plate 1 relative to the fixing groove 17. The fixing ear 16, the fixing groove 17 and the carbon fiber cover 2 are penetrated and threadedly connected with a fixing bolt 18, which facilitates the installation and disassembly of the carbon fiber cover 2 and the carbon fiber bottom plate 1, and is more stable and safe.
