Abstract
The utility model relates to a flexible cellular material of convex unit, flexible cellular material include at least two sets of tandem arrangement's convex layer, every group convex layer includes at least one convex unit that connects gradually from beginning to end, every convex unit comprises first plane, first arch, second plane, second arch, and first bellied height is greater than the bellied height of second, and first bellied outside width is less than the bellied internal width of second, in the front -seat convex unit second arch of first protruding anterior embedding in the convex unit of back row, its terminal surface passes through the adhesive linkage and connects. A flexible cellular material of convex unit, has improved the intensity and the modulus ratio of honeycomb, inlays some flexible regional rigidity that has suitably reduced the structure in the honeycomb, and under the same deformation condition, honeycomb's inner stress is low, honeycomb warpage phenomenon can not appear.
Description
Technical field
This utility model relates to a kind of cellular material, is specifically related to the flexible honeycomb material of a kind of convex unit.
Background technology
In the radome of sandwich designs, need honeycomb Transfer of Shear, thus whole honeycomb sandwich construction is supported, in order to realize this purpose, it is necessary to the existing enough rigidity of honeycomb, there is again enough intensity.In actual use, the shear strength of radome honeycomb texture is the key factor of restriction radome honeycomb sandwich construction design, and this is relatively low with modulus ratio mainly due to the intensity of honeycomb, and some honeycomb exists the warping phenomenon outside face, in the occasion of some deep camber, limit the application of honeycomb.
Summary of the invention
For solving the problems referred to above, this utility model discloses the flexible honeycomb material of a kind of convex unit, can improve intensity and the modulus ratio of honeycomb, and not have honeycomb warping phenomenon.
For the problems referred to above, design of the present utility model is: the flexible honeycomb material of a kind of convex unit, and described flexible honeycomb material includes at least two groups tandem convex layer, and often group convex layer includes the convex unit that at least one head and the tail is sequentially connected with；Each convex unit is made up of the first plane, the first projection, the second plane, the second projection, and the height of the first projection is more than the height of the second projection, and the external width of the first projection is less than the inner width of the second projection；The first raised front portion in heel row convex unit embeds in front-seat convex unit the second projection, and its end face is connected by adhesive linkage；Multiple rows of convex layer carries out bonding formation cellular board, and has the flexible region of formation in cellular board, thus suitably reduces the rigidity of structure, and under identical deformation condition, the internal stress of honeycomb texture is low, will not cause the honeycomb warping phenomenon that hexagon cellular often has.
Preferably, described convex unit is made up of the first plane, the first projection, the second plane, the second projection, the 3rd plane, and convex unit is in turn connected to form convex layer, and the head and the tail of convex layer front and rear row are interconnected to form flexible honeycomb structure.
Preferably, the external width of the first described projection adapts with the inner width of the second projection, it is easy to the first projection is embedded in the second projection, and does not produce gap, it is to avoid produces between the convex unit of front and rear row and loosens, affects the comprcssive strength of cellular material.
Preferably, the described protruding side, front end of heel row convex unit first is connected by adhesive linkage with the inner side of front-seat convex unit the second projection, first protruding side, front end sets adhesive linkage, strengthens the fastness between the second projection, prevent from producing between the convex unit of front and rear row loosening.
Preferably, the height h of each several part of described convex unit is identical, makes convex unit each several part at grade, meets the application demand of cellular material.
Beneficial effect: this utility model uses the flexible honeycomb material of convex unit composition, improve intensity and the modulus ratio of honeycomb, flexible region is had in cellular board, thus suitably reduce the rigidity of structure, under identical deformation condition, the internal stress of honeycomb texture is low, thus, the honeycomb warping phenomenon that hexagon cellular often has will not be caused.

Detailed description of the invention
The flexible honeycomb material of a kind of convex unit, as it is shown in figure 1, described flexible honeycomb material includes at least two groups tandem convex layer, often group convex layer includes the convex unit that at least one head and the tail is sequentially connected with；Each convex unit is made up of first plane the 1, first projection the 2, second plane the 3, second projection 4, and the height of the first projection 2 is more than the height of the second projection 4, and the external width of the first projection 2 is less than the inner width of the second projection 4；In heel row convex unit first protruding 2 is anterior to be embedded in front-seat convex unit the second projection 4, and its end face is connected by adhesive linkage 5.The external width of the first described projection 2 adapts with the inner width of the second projection 4, it is easy to the first projection 2 is embedded in the second projection 4, and does not produce gap, it is to avoid produces between the convex unit of front and rear row and loosens, affects the comprcssive strength of cellular material.The three-dimensional structure diagram of convex unit as shown in Figure 2, the height h of each several part of described convex unit is identical, makes convex unit each several part at grade, meets the application demand of cellular material.As described in Figure 3, the flexible honeycomb material that the arrangement of convex unit is formed.Flexible region in encircled in being embedded with such as Fig. 3 in the flexible honeycomb plate formed, flexible region suitably reduces the rigidity of structure, and under identical deformation condition, the internal stress of honeycomb texture is low, thus, the honeycomb warping phenomenon that hexagon cellular often has will not be caused.
