Embodiment

[0043] figure 1The carbon fiber composite unmanned aerial vehicle fuselage prepared for the present invention includes a front cover 101, a rear cover 102 and a fuselage shell 200, and the fuselage shell 200 is provided with a wing opening 201, an air inlet 202 and a tail section 203. Using carbon fiber unidirectional prepreg, carbon fiber fabric prepreg and lightweight foam as raw materials, the prepreg 2 is laid on the inner surface of the mold 1 by lap joint overall lay-up technology, and finally the autoclave molding technology is used to manufacture Obtained carbon fiber composite drone fuselage.

[0044] In this example:

[0045] Carbon fiber unidirectional prepreg: Jiangsu Hengshen / EM101-35%-A3-U-180gsm is used specifically, with a single layer thickness of 0.15mm. The carbon fiber unidirectional prepreg includes unidirectional carbon fiber, epoxy resin, and toughening agent equal components, the weight percentage of epoxy resin in the carbon fiber unidirectional prep...

Abstract

The invention discloses an unmanned aerial vehicle body integrated molding technology. Carbon fiber prepreg and lightweight foam are used as raw materials, are paved on the inner wall of a double-female mold combination mold by adopting a prepreg lapping joint integral layering technology, and then are integrally solidified and molded by adopting an autoclave molding technology. The unmanned aerial vehicle body integrated molding technology has the beneficial effects that the technology is simple and is easy to operate; the molding time is short; the product size is accurate and controllable;and a manufactured unmanned aerial vehicle body has high strength, good rigidity, light dead weight and a smooth and fat surface, is easy to maintain routinely and is suitable for large batch production.

Description

technical field [0001] The invention relates to the field of preparation of unmanned aerial vehicles, in particular to an integrated molding process of an unmanned aerial vehicle fuselage. Background technique [0002] With the continuous advancement of science and technology, UAVs have been widely used in military and civilian fields due to their distinctive features, especially in military reconnaissance, aerial photography, agricultural plant protection, surveying and mapping, disaster relief and rescue. As an important part of the drone, the fuselage of the drone carries various sensors, navigation systems, engines and other functional equipment, which puts strict requirements on the materials of the drone fuselage. , poor fatigue resistance, and poor corrosion resistance cannot meet the needs of the lightweight development of drone fuselages, while polymer engineering plastics have low mechanical properties and can only be used for consumer-grade drone fuselages.
