Description
Technical field
The utility model belongs to composite material honeycomb sandwich board field, and in particular to a kind of composite material cellular sandwich is hardened
Structure.
Background technology
Composite material honeycomb sandwich board is widely used in each due to having the advantages that the high structure efficiency of high rigidity/weight ratio
The Flight Vehicle Structure of kind efficient and light weight.Composite material cellular sandwich harden structure belongs to the component level in the experiment of composite material building block system
Experiment, the experiment are used for stability, post-impact compression and the damage for studying and verifying composite material cellular sandwich harden structure
The performance indicators such as tolerance limit, the verification for honeycomb sandwich board in the experiment of composite material building block system are essential.
Existing composite material honeycomb sandwich board is not strengthened two loading ends generally when designing lateral pressure test part, directly in bee
Sandwich panels both ends apply load, this kind of structure type easily causes the uneven provocative test part bending of testpieces upper and lower panel loading,
So as to cause testpieces abnormal destruction；Simultaneously as two loading end of testpieces directly bears to apply load, battenboard end is easily caused
Radical first destroys, it is impossible to obtains the real failure mode and fail data of battenboard testpieces, causes testpieces to break in advance
It is bad, test failure, and then development progress is influenced, cause huge waste.
Utility model content
The purpose of this utility model is to provide a kind of composite material cellular sandwich harden structure, the prior art is overcome or alleviated by
At least one drawbacks described above.
The purpose of this utility model is achieved through the following technical solutions：A kind of composite material cellular sandwich harden structure, is used for
Lateral pressure test, including composite material top panel, composite material lower panel, honeycomb and foamed glue, composite material top panel is with answering
The advance curing molding of condensation material lower panel, foamed glue filling, which cures, to be arranged on the loading end at honeycomb both ends, and honeycomb both sides are split
Composite material top panel and composite material lower panel, between composite material upper and lower panel and honeycomb three cementing co-curing into
Shape.
Preferably, the composite material top panel and the composite material lower panel are molded according to composite material laminated board
The advance curing molding of technique.
Preferably, honeycomb lattice space, and both ends of the surface are filled up after the foaming adhesive curing of honeycomb both ends embedding
Flush.
Preferably, the composite material top panel and the composite material lower panel are cementing solid altogether by glued membrane and honeycomb
It is melted into shape.
A kind of beneficial effect of composite material cellular sandwich harden structure provided by the utility model is, without to experiment
Part accessory size is modified, and foaming adhesive curing need to be only pre-charged with the honeycomb of honeycomb sandwich board both ends, and technique is simple,
Honeycomb sandwich board after embedding can guarantee test debugging it is easy, success of the test rate lifting, result of the test being capable of actual response examination
Test the failure mode of part and obtain ideal test data, be conducive to study and verify composite material honeycomb sandwich board stable structure
The performance indicators such as property, post-impact compression and damage tolerance, avoid cellular sandwich harden structure and easily cause end in stand under load
Premature degradation, it is difficult to obtain the technical barrier of true failure mode and result of the test.

Example, shall fall within the protection scope of the present invention.
The composite material cellular sandwich harden structure of the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 2, a kind of composite material cellular sandwich harden structure, for lateral pressure test, mainly including composite wood
Expect top panel 1, composite material lower panel 2, honeycomb 3 and foamed glue 4.Composite material top panel 1 and composite material lower panel 2 are advance
Curing molding, foamed glue 4 is filled on the loading end at 3 both ends of honeycomb in advance to be cured, and 3 both sides of honeycomb split composite material top panel
1 with composite material lower panel 2, cementing co-curing shaping between 3 three of composite material upper and lower panel and honeycomb.
The process program of the utility model is：The first step, composite material top panel 1, composite material lower panel 2 press composite wood
Laminae correlation moulding process cures in advance.Second step, 3 both ends foamed glue 4 of honeycomb is filled, then related by foamed glue
Technological requirement curing molding, while honeycomb lattice space is filled up after the curing of foamed glue 4 of embedding, and ensure the both ends of the surface depth of parallelism,
I.e. both ends of the surface flush.3rd step, composite material top panel 1, composite material lower panel 2 are glued by glued membrane together with honeycomb 3
