Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:
[0019] A method for making a concave hexagonal flexible honeycomb, as attached Figure 1-2 As shown, the honeycomb is composed of several identical concave hexagonal honeycomb units arranged in a staggered manner, the concave hexagon is composed of two isosceles trapezoids with overlapping upper bases, and the isosceles trapezoid is composed of three regular triangles , that is, the length of the upper and lower bases of the concave hexagon is the same, the length of the hypotenuse is 1 / 2 of the length of the upper / lower base, and the four top and bottom angles are 60°. During manufacture, a honeycomb mold 1 and several unit dies 2 are used for manufacture. as attached image 3 And attached Figure 4 As shown, the honeycomb mold is a box-shaped structure with an open upper end, which is a steel mould, and the base plate of the honeycomb mold 1 ...

The invention discloses a manufacturing method for a concave hexagonal flexible honeycomb. A honeycomb mold and a plurality of unit pressing molds are adopted for manufacturing. The manufacturing method comprises the following steps that (1) honeycomb paper is cut into paper slips with required widths; (2) a mold releasing agent is smeared on a bottom plate of the honeycomb mold; (3) the two faces of a first layer honeycomb paper slips are glued and put in air; (4) a first layer of honeycomb paper is laid on the bottom plate of the honeycomb mold; (5) the mold releasing agent is smeared on all the unit pressing molds; (6) each mold groove is internally provided with the corresponding unit pressing mold, the first layer of honeycomb paper is pressed through the unit pressing molds, and heavy pressing plates are arranged on the unit pressing molds to press the unit pressing molds; (7) the two faces of a second layer honeycomb paper slips are glued and put in air; (8) a second layer of honeycomb paper is laid on the first layer unit pressing molds, the second layer of honeycomb paper is pressed by arranging the unit pressing molds, and heavy pressing plates are arranged on the second layer unit pressing molds to press the second layer unit pressing molds; (9) the step (7) and the step (8) are repeated, and other layer honeycomb paper is sequentially laid; and (10) heating curing treatment is conducted.
Description
technical field [0001] This aspect relates to a method for manufacturing a concave hexagonal flexible honeycomb. Background technique [0002] There are many structures in the project that need to be made into a honeycomb sandwich structure with a large curvature. The ordinary hexagonal honeycomb sandwich structure in the case of large curvature is difficult to resist the requirements of large in-plane deformation and high out-of-plane load during production and use, and saddles are prone to appear. Effect, so it is necessary to adopt a honeycomb sandwich structure that can produce large deformation in the plane while the bearing capacity of the outside plane will not be reduced. Under this condition, various structural forms of flexible honeycomb sandwich structures are produced. By designing the flexible honeycomb The structural form and size are used to achieve the large deformation requirements in the honeycomb plane. [0003] The deformability and bearing capacity of t...
