Abstract
The utility model belongs to technical field of composite materials, be specifically related to a kind of recessed hexagon flexible honeycomb structure, described honeycomb is staggered by several identical recessed hexagonal honeycomb unit and forms, the isosceles trapezoid that described recessed hexagon is overlapped by two upper bases forms, and described isosceles trapezoid is made up of three equilateral triangles.The utility model breaches conventional hexagonal cell when compared with restriction on-deformable when deep camber, and in-plane deformation ability is better than conventional hexagonal cell, therefore solves conventional hexagonal cell shaping and occur the shortcoming of saddle effect in using.
Description
Technical field
The utility model belongs to technical field of composite materials, is specifically related to a kind of recessed hexagon flexible honeycomb structure.
Background technology
In radome, often there is a lot of structure to there is larger curvature, in this deep camber situation, still adopt conventional hexagonal shape honeycomb sandwich construction, be difficult to resist the requirement of high-mechanic outside large deformation and face in the face in making and using, easily occur saddle effect.
Utility model content
Technical problem to be solved in the utility model is: the flexibility increasing honeycomb, avoids honeycomb sandwich construction to occur saddle effect when larger curvature.
The technical solution of the utility model is: a kind of recessed hexagon flexible honeycomb structure, and described honeycomb is made up of several identical alternate being staggered of recessed hexagonal honeycomb unit.The isosceles trapezoid that described recessed hexagon is overlapped by two upper bases forms, and described isosceles trapezoid is made up of three equilateral triangles.
The beneficial effects of the utility model are: breach conventional hexagonal cell when compared with restriction on-deformable when deep camber, in-plane deformation ability is better than conventional hexagonal cell, therefore solves conventional hexagonal cell shaping and occur the shortcoming of saddle effect in using.
Accompanying drawing explanation
Fig. 1 is recessed hexagon flexible honeycomb unit;
Fig. 2 recessed hexagon flexible honeycomb plate schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The recessed hexagon flexible honeycomb of the utility model indication is upper and lower base length is 6mm, and hypotenuse length is 3mm, and upper and lower four drift angles are the recessed hexagonal cells of 60 °, and unit form as shown in Figure 1.
The cellular board be made up of recessed hexagon flexible honeycomb unit as shown in Figure 2.Cellular board is made up of some groups of identical alternate being staggered of recessed hexagonal honeycomb unit.
The recessed hexagon flexible honeycomb structure that the utility model provides is compared to existing hexagonal cell structure, and its performance advantage is:
The total deformation of this recessed hexagon flexible honeycomb conventional hexagonal cell and recessed hexagon flexible honeycomb under equal large side crops industry effect of utility model is respectively 6.46mm, 113.3mm, and recessed hexagon flexible honeycomb is more yielding than conventional hexagon cellular as seen from the figure.
Claims (1)
1. a recessed hexagon flexible honeycomb structure, it is characterized in that, described honeycomb is staggered by several identical recessed hexagonal honeycomb unit and forms, and the isosceles trapezoid that described recessed hexagon is overlapped by two upper bases forms, and described isosceles trapezoid is made up of three equilateral triangles.
