Problems solved by technology

[0005] Although the good physical properties of the polypropylene microcellular foamed sheet are ideal raw materials for aircraft wings, the texture of the polypropylene microcellular foamed sheet has a certain toughness due to the micropores in the sheet and cannot be machined. Therefore, there is no product that uses polypropylene microcellular foamed sheet as raw material to prepare wings in the field of unmanned aerial vehicles.

Embodiment 1

[0026] This embodiment provides a manufacturing process for drones, that is, using polypropylene microporous foam plates as raw materials to prepare drone accessories.

[0027] Wherein, the UAV accessories include but not limited to wings, fuselage, empennage and so on.

[0028] For polypropylene microporous foam sheet, although microporous brings the above-mentioned advantages, it also brings the problem of difficult machining, that is, due to microporous, polypropylene microporous foam sheet is light in texture and has certain toughness. , but it is not conducive to the preparation of corresponding accessories by mechanical processing.

[0029] Therefore, aiming at the technical problem of difficult mechanical processing of polypropylene microcellular foamed sheet, the first step of the present invention is to make the polypropylene microcellular foamed sheet meet the processing hardness required for mechanical processing, and then perform mechanical processing by CNC numeri...

Embodiment 2

[0051] On the basis of Embodiment 1, Embodiment 2 provides an unmanned aerial vehicle.

[0052] The UAV includes a wing made of polypropylene microporous foam sheet; and the wing is prepared by the UAV preparation process described in Example 1.

[0053]After the wing is made of polypropylene microcellular foamed sheet, it has the advantages of lightness and toughness made of polypropylene microcellular foamed sheet, and makes the wing resistant to stretching, compression, torsion, impact, etc. Capabilities are increased, extending the lifespan of the drone.

Abstract

The present invention relates to a UAV preparation process and a high-strength UAV prepared by the process. In the UAV preparation process, polypropylene microporous foam boards are used as raw materials to prepare wings. The specific steps are as follows: step S1, improve The processing hardness of the polypropylene microcellular foamed sheet; step S2, cutting the polypropylene microcellular foamed sheet to form a semi-finished wing; and step S3, performing thermocompression molding on the semi-finished wing; the unmanned The machine preparation process proposes a new preparation and processing method of polypropylene microcellular foamed sheet as raw material, so that the polypropylene microcellular foamed sheet is used as the raw material for the processing of UAV wings, that is, the polypropylene microcellular foamed sheet is used Realize the preparation of the wing.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a preparation process for unmanned aerial vehicles and an unmanned aerial vehicle. Background technique [0002] Polymer microporous foam material specifically refers to a polymer porous foam material with a cell size of less than 100 μm and a cell density greater than 1.0×106 cells / cm 3 . Due to its light weight, high strength, and material saving characteristics, microcellular foam materials have broad application prospects. Among many polymer microcellular foam materials, polypropylene (PP) microcellular foam materials have good mechanical properties, high heat distortion temperature, chemical resistance and other properties, and the cells are interconnected. Open-cell polypropylene microporous foam materials can be used in fields such as filtration, separation, sound absorption and ventilation. [0003] Therefore, this material is widely used in heat insulation panel...
