Specific embodiment
With reference to the accompanying drawing and the embodiment of the present invention is further detailed to the manufacturing method work of honeycomb core material of the invention
Explanation.
As shown in Figure 1 to 4, the honeycomb stem of the prior art, all 2 structures of honeycomb sandwich layer are all the same, honeycomb sandwich layer 2
The bonding or 3 centre distance of weld on surface be adhesive strip or weld four times of a width, adjacent two layers honeycomb sandwich layer 2 it
Between bonding or weld 3 be staggered.Every layer of honeycomb sandwich layer 2 is single layer structure.
As shown in Fig. 5~Figure 10, the honeycomb core material of the manufacturing method of honeycomb core material of the present invention production, the honeycomb core material it is every
The core wall of a honeycomb cell 1 includes at least two layers.The effect for improving honeycomb core material intensity is realized, is reduced in process
Drawing force size；It further reduced a possibility that tearing at honeycomb sandwich layer bonding location.It avoids in the prior art, honeycomb hole
The core wall of lattice is single layer structure, can only be by increasing core wall thickness in order to improve the bearing capacity of honeycomb core material；But core wall
Thickness increases, in order to complete stretching process, it is desirable to provide biggish drawing force, however drawing force increases, between honeycomb sandwich layer
Bonding location just will appear tearing, reduce yield rate.
In order to meet different honeycomb core material volume size requirements, and satisfaction to honeycomb core material convenient processing and manufacture, honeycomb
Core material includes multiple honeycomb sandwich layers 2, and honeycomb sandwich layer 2 is fixedly connected between each other.
In order to reduce manufacturing procedure difficulty, facilitates the manufacturing, be bonded or weld between honeycomb sandwich layer 2.When using viscous
When connecing, bonding agent can be the aluminum honeycomb core material binder of epoxy-modified phenol formaldehyde-rubber type.It is also possible to Traldite
420A/B。
In order to avoid honeycomb sandwich layer 2 is blocked up, the drawing force needed is excessive；Or honeycomb sandwich layer 2 is excessively thin, honeycomb core material carrying
The too small defect of power, the thickness of honeycomb sandwich layer 2 are selected as 0.02mm~0.2mm.Preferably, the material thickness of honeycomb sandwich layer 2 is
0.05mm。
In order to facilitate drawing and forming, also have the advantages that preferable load-bearing capacity and buffer capacity, bee using honeycomb
Socket bore lattice 1 are hexagonal structure or close to hexagonal structure.
It in order to facilitate drawing and forming, avoids honeycomb side length too small, in drawing process, is bonded or welded that area is too small to be easy to tear
Destruction is split, is unfavorable for forming；Or honeycomb side length is excessive, cellular densities are excessive, bearing capacity and excessively small defect, hexagon
Structure is selected as close to the side length of hexagonal structure
1mm~10mm.Preferably, hexagonal structure or the side length close to hexagonal structure are 1.5mm.
In order to avoid the number of plies is excessive, process is tedious and bonding location is easy to happen tearing, it is preferred that honeycomb cell 1
Core wall is two layers.Each honeycomb sandwich layer 2 divides for body layer 21 and enhancement layer 22, the bonding of the body layer 21 of adjacent cell sandwich layer or
Person's weld 3 is staggered, and enhancement layer 22 is aligned setting with the bonding or weld 3 of body layer 21.Enhance layer surface bonding
The either half of layer surface bonding or the centre distance of weld based on the centre distance of weld.Usually bonding or
The width of person's weld 3 is close with the side length of the honeycomb cell.
In order to meet the needs of different applicable situations, the core wall material of honeycomb cell 1 can for metal foil or paper or
Person's plastics.It is also possible to the materials such as aramid fiber, carbon fiber, glass fibre.
As shown in the table, by taking the aluminum honeycomb core material of side length 1.5mm as an example, the bee of flat compressed intensity 15MPa in order to obtain
Nest core material, using the comparison of the drawing force of previous single layer structure and multilayered structure of the present invention, it can be seen that：Same plane pressure
When contracting intensity, double-layer structure is easier successfully to be pulled open.
The manufacturing method of the honeycomb core material, includes the following steps：
S1, bonding or weld 3 and non-adhesive or weld are divided in body layer 21 and 22 surface of enhancement layer；It is described
The adjacent bonding in 21 surface of body layer or the centre distance of weld 3 are the adjacent bonding in 22 surface of enhancement layer or weld
Two times or so of 3 centre distance；The usually width of bonding or weld 3 is close with the side length of the honeycomb cell；
S2, print glue or cored solder are applied in 21 surface of body layer bonding or weld 3；22 surface of enhancement layer bonding or
Person's weld 3 applies print glue or cored solder；
S3, at least one layer of enhancement layer 22 is set between adjacent body layer 21, by the bonding of enhancement layer 22 or weld 3
Overlapping is aligned with the bonding or weld 3 of body layer 21；Bonding or weld 3 between adjacent body layer 21 is staggeredly heavy
It is folded；
S4, by stretching-machine stretch, perpendicular to 21 surface of body layer apply drawing force, body layer 21 non-adhesive or
Weld forms hexagon or the honeycomb cell 1 close to hexagon.
In the step S3, one layer of enhancement layer 22 is set between adjacent body layer 21.
Shown in Fig. 9, based on 21 surface of layer bonding perhaps 3 spacing D of weld be the width for printing glue or solder, C is to print
The spacing of glue or solder.
It is the width that 22 surface of enhancement layer is bonded that perhaps 3 spacing D of weld is bonding or weld 3 shown in Figure 10,
C/2 is the spacing for printing glue or solder, and C is about 2 times of C/2 or so.
