Problems solved by technology

At present, the protective cover of the UAV has defects such as slow dynamic response, not crashworthy, easy to deform, large mass, and limited protection capability. The rigid impact on the cover will be directly transmitted to the fuselage, causing damage to the fuselage, and even damage the electronic components inside the fuselage

[0025] Such as figure 1 As shown, the present invention provides a composite plate 100, comprising a carbon fiber layer, a glass fiber layer and a Kevlar layer, acting on the fuselage shell of an aircraft; the arrangement of the plates from outside to inside is carbon fiber layer 101, glass fiber layer 102 and, Kevlar layer 103. It can be seen from the above scheme that in the multi-layer structure, the arrangement of the carbon fiber layer 101, the glass fiber layer 102, and the Kevlar layer 103 has a thickness ratio of 1:2:7. The overall weight of the aircraft has been greatly reduced, and the structural strength of the composite plate has been enhanced to improve the impact resistance. At the same time, the outer carbon fiber layer structure is anti-ultraviolet and protects the inner high-strength Kevlar layer from ultraviolet decomposition. The glass fiber layer has a higher elastic modulus, which can improve the toughness of the protective frame and prevent the brittle c...

[0035] The difference between this embodiment and the first embodiment lies in the structure of the offline network.

[0036] Such as Figure 5 As shown, a support ring 8 is arranged in the middle of the lower wire mesh 332, and thread holes (not shown) for threading are processed on the side wall protection frame 322 and the support ring 9, and the pull wires are criss-crossed and run through the side wall protection frame 322 and the support ring 9 Between them, a lower wire mesh 332 is formed, and there are gasket sleeves (not shown) at the contact places between the pull wires and the holes. The seal between the gasket sleeve and the lower wire mesh 332 and the side wall protection frame 322 is completely sealed to prevent airflow from passing through the small holes on the frame form jitter. Setting the support ring 9 facilitates the installation of the aircraft drive rotor 412 .

Abstract

The invention provides a composite plate. The composite plate comprises a carbon fiber layer, a glass fiber layer and a Kevlar layer from outside to inside. According to the composite plate disclosed by the invention, the limitations of properties of a single material are overcome, the rigidity and the tensile capacity of the composite sheet are improved, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to a composite plate, in particular to a high-rigidity, high-strength composite plate and an aircraft made of the composite plate. Background technique [0002] Aircraft include unmanned aerial vehicles and manned aerial vehicles. Unmanned aerial vehicles are referred to as "drones" for short, which are unmanned aircraft controlled by radio remote control equipment or embedded programs. At present, the rotor UAV is widely used. Its power comes from the lift provided by the high-speed rotation of the rotor. By controlling the different rotation speeds of each rotor, different actions such as lifting and hovering of the UAV can be realized. [0003] Today's unmanned aerial vehicles use a single material for many fuselage materials, making the aircraft vulnerable to impact and damage. Carbon fiber materials are brittle and easy to break; glass fiber materials have low structural strength and are prone to deformation under impact; Kev...
