A method for manufacturing light-weight and high-strength bionic insect wings

Abstract

The invention discloses a manufacturing method for a light-mass high-strength bionic insect wing. A wing supporting framework is made of carbon fibers and comprises a main wing beam and three reinforced wing ribs. A wing surface is a Mylar film. The manufacturing method comprises the steps that 1, two unidirectional carbon fiber prepregs of which the fiber directions form a certain angle are stacked and pressed forcefully; 2, by means of a laser cutting mode, the shape of the wing supporting framework is cut on the double-layer carbon fiber prepreg, and the shape of the wing surface is cut on the Mylar film; 3, the surface of the carbon fiber prepreg is uniformly smeared with epoxy resin high temperature glue; 4, redundant carbon fibers around the carbon fiber prepreg supporting framework are removed, and the cut Mylar film is placed on the framework; and 5, the carbon fiber framework and the Mylar film are placed in an oven, great pressure is applied to the wing, and heating is conducted for 80 minutes at the temperature of 70 DEG C. The bionic wing manufactured based on the manufacturing method is light in mass and high in strength. The manufacturing method is suitable for manufacturing centimeter-level and millimeter-level bionic insect wings.

Description

technical field [0001] The invention relates to a material selection and processing method in the preparation process of light and high-strength bionic insect wings, and belongs to the technical fields of processing engineering and material processing. Background technique [0002] Since the 21st century, with the development of micromachining, materials, electronics and other disciplines, based on the principle of bionics, insect-like micro flapping wing aircraft (wingspan less than 5cm) using micro-mechanical electronic system technology has gradually become a research hotspot. One of the key technologies in the development of insect-scale miniature flapping-wing aircraft is the manufacturing method of bionic wings. Since the bionic wing is in a high-frequency and large-scale flapping state during work, this requires that the wing surface and the supporting frame of the bionic wing have high enough strength; in addition, in order to improve the aerodynamic efficiency, the ...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a light-weight and high-strength bionic insect wing manufacturing method for the existing problems in the processing of the existing bionic insect wings, which avoids the high strength and light weight in the overall processing of the support skeleton wing surface. The problem that the quality cannot be taken into account solves the problem of low local strength, need for splicing and poor fit in the separate processing of carbon fiber and film, and is suitable for the preparation of bionic insect wings from centimeters to millimeters
