Any modification is replaced and is improved.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to accompanying drawings and in conjunction with the embodiments.
In a first aspect, the present invention provides a kind of preparation method of the flexible honeycomb of heart-shaped cell, Fig. 2 is in preparation process
Middle heart mould is inserted into the status diagram in flexible honeycomb cell.The preparation method of the flexible honeycomb of heart-shaped cell includes following step
Rapid S110 ~ step S140：
Step S110 is to apply core bar glue, and core bar glue is coated the surface of flexible thin material is equally spaced using glue spreader.
Wherein, flexible thin material can be aramid paper, metal foil either other similar flexible thin plates etc..
In the present embodiment, the flexible thin material in the step uses NOMEX aramid papers, using glue spreader aramid paper side table
Face it is equally spaced coat core bar glue, can also be to be coated all in accordance with equally spaced mode in the both side surface up and down of aramid paper
Core bar glue, core bar glue can be the heat for bonding or generating bonding between the flexible thin material for honeycomb
Thermosetting resin material, the core bar glue specifically applied on the aramid paper of the present embodiment is using J-80B NOMEX paper honeycomb sandwiches
Adhesive.
Step S120 is bonded for lamination, is bonded according to the lamination of the mutually equally spaced dislocation of neighbouring two layers of core bar glue
Mode, flexible thin material's lamination that multilayer is coated with to core bar glue are bonded to form superimposed sheet.
In this step, in the flexible thin material that multilayer is coated with to core bar glue（Aramid paper 2）Successively carried out lamination
Bonding, needs to ensure the flexible thin material that adjacent upper layer and lower layer is mutually bonded in lamination process（Aramid paper 2）Between glued
The core bar glue connect mutually equally spaced dislocation each other, with ensure the adjacent core bar glue on each layer of flexible thin material respectively with the layer
The upper and lower be bonded.
Step S130 is hot-press solidifying, and the superimposed sheet is carried out hot pressing, makes the core adhesive curing of lamination abutting edge.
In this step, by layer flexible layer material（Aramid paper 2）Lamination is bonded the superimposed sheet to be formed and is placed on and core
It in the comparable temperature environment of glue thermoset condition, pressurizes, makes between each overlapping layers in the thickness direction of superimposed sheet
Core bar glue cures, so that the bonding between every layer of flexible thin layer is more secured.
Step S140 is drawing and forming, and the superimposed sheet after hot pressing is stretched, and superimposed sheet is made to be stretched in overlapping thickness direction
Exhibition can form the honeycomb of regular hexagon cell, then stretch into heart-shaped mould 1 in regular hexagon cell, and will using plate washer
The surrounding of honeycomb equipped with heart-shaped mould 1 is fixed, and honeycomb is made to be deformed into along the end to end heart of draw direction
Cell 4, heart-shaped cell 4 have arc flexible edge 5, wherein heart-shaped mould 1 be cross section be heart rod piece, heart-shaped cell 4 it
Between end to end place be core glue sticking at 3.The state that heart-shaped mould 1 is inserted into flexible honeycomb cell is shown in Figure 1.
In this step, can in the fixed tension belt of the top layer of superimposed sheet and lowest level, by pull tension belt to
It overlaps thickness direction to stretch, when each lamination being made to be stretched over maximum position, the honeycomb of regular hexagon cell can be formed.So
Afterwards by heart-shaped mould 1 be inserted into cell in, as shown in Figure 1, the heart mould 1 is cross section be heart hollow stem or solid hopkinson bar, this reality
Apply heart-shaped mould of the example using hollow rod.
In addition, the preparation method of the flexible honeycomb of the heart-shaped cell 4 of the present invention can also include the following steps S150 ~ step
S170：
Step S150 is heat-shaping, that is, the honeycomb equipped with heart-shaped mould 1 is put into shaping baking oven, makes honeycomb
The unit of heart-shaped cell 4 is shaped.
In this step, honeycomb is placed in 265 DEG C ± 5 DEG C of oven temperature environment, keeps the temperature 20 ± 5min, made each
Heart-shaped cell 4 is shaped.
Step S160 is form removal impregnation, that is, after the above step is finished, by heart-shaped mould 1 and plate washer from the honeycomb after sizing
It is removed in structure.Then the honeycomb of heart-shaped cell 4 is subjected to gum dipping process.
Step S170 cuts for cured sheets, that is, the honeycomb after impregnation is carried out baking and curing, then according to compact dimensions
It is required that progress sawing or piece cut processing, the flexible honeycomb structure of the heart-shaped cell 4 of predetermined dimension is obtained.（Referring to Fig. 2）
In practice, the mode that impregnating resin may be used carries out gum dipping process, then after the completion of impregnation, can use heating or
Air-dried mode has made baking and curing.
Second aspect, as shown in Fig. 2, the present invention provides a kind of heart-shaped cells prepared by the preparation method by first aspect
Flexible honeycomb.The cell of the flexible honeycomb is end to end heart-shaped cell 4, the end to end place between the heart cell 4
It is at core glue sticking 3,3 both sides are the flexible edge 5 of arc at core glue sticking.It is, foramen cordiforme adjacent to each other
The common edge of lattice 4 is the flexible edge 5 of arc.
To sum up, the flexible honeycomb for the heart-shaped cell that prepared by the present invention at core glue sticking with it is outer be arc flexibility
Side has preferably respectively to flexibility, while having physically better and chemical property, and preparation method is simple, saves production
Cost when the flexible honeycomb of the heart cell is as core structure, not will produce structural damage in process, the present invention
The flexible honeycomb of heart-shaped cell be applicable to the more stringent field of use condition.
