Description
Technical field
The utility model belongs to sandwich plate field more particularly to a kind of lateral honeycomb sandwich panel.
Background technique
Sandwich plate is usually made of the core material between upper and lower panel and upper and lower panel, and core material has gumminess, by top and bottom
Plate is connected as an entirety, and core material is similar to the web of I-steel, the horizontal drawing stress of shearing force and normal direction in bearing plane.Phase
Than in traditional steel, sandwich plate has functional, and widely used, the advantages such as light-weight become in nowadays structure lightened
Under gesture, sandwich plate has obtained more and more applications in engineering field, especially in European and American areas, has sandwich plate heavy construction
Using domestic sandwich plate is mainly used in manned space flight, and satellite etc. requires architecture quality relatively high field.
Honeycomb sandwich panel derives from biosimulation field, designs with reference to the cellular shape of honeybee, especially in macromolecule
The many core materials in field can realize large-scale production by prefabricated corresponding mold by pouring molding.Honeycomb sandwich panel conduct
A kind of special case of Sandwich Plates, design feature are mainly reflected in normal direction bearing capacity and are much larger than common sandwich plate, while bending resistance
The common sandwich plate of the rigidity quality such as relatively is more excellent.Legacy cellular sandwich plate also exposed while improving structural mechanical property as
Lower Railway Project: the contact area of honeycomb interlayer board core material and panel first is smaller, and interface adhesion is very poor, answers in Practical Project
Easily occur the failure modes such as delamination in；The honeycomb hole secondly because core surfaces gather leads to overall structure sound insulation and noise reducing, heat preservation
Heat-proof quality substantially reduces, and reduces the application surface of honeycomb sandwich panel；Furthermore legacy cellular sandwich plate due to design feature, thus
Cause integrally-built buckling stability poor, easily occurs panel under certain limiting conditions and local buckling or whole hair occur
Raw buckling failure, the anti-thorough performance of inclining of legacy cellular sandwich plate is general in addition, therefore is not used to the decks such as warship or ship outer casing.
Existing honeycomb sandwich panel patent guarantees sandwich plate mechanical property, such as Southeast China University by adding reinforcement structure mostly
CN201510976402.X patent disclosure by adding " arc plate " Lai Tigao overall structure at each hexagon node
Can, the method can improve the side pressure buckling stability of whole plate to a certain extent, and can increase the normal direction bearing capacity of structure,
But the size of arc plate needs are prepared according to the size of honeycomb sandwich panel, it can not be a large amount of prefabricated, and its technology difficulty
Reduce also with honeycomb pore size and increase, is difficult to adapt to the field demand of large-scale engineering applications.For another example Nanchang University of aviation
CN206781131U patent disclosure improves the sound insulation property of honeycomb sandwich panel, the method energy by adding resonance sound insulation thin plate
Enough improve honeycomb sandwich panel sound insulation property, but resonate sound insulation thin plate itself manufacture craft and mounting process it is more complicated and at
This is higher, is difficult large area use, is not easy to practical implementation.
Therefore, now needing one kind can effectively solve the problem that above-mentioned technical problem, and can also further promote reduction laminate weight
Sandwich plate.
Utility model content
Purpose of utility model: small, specific strength that the purpose of the utility model is to provide a kind of density and specific stiffness are excellent, laterally
The lateral honeycomb sandwich panel that intensity is strong and buckling stability is strong.

Topic, and the buckling stability of sandwich plate is effectively increased, the thermal insulation property and sound insulation property of sandwich plate are furthermore also effectively increased,
It is easy to implement industrialized production.Preferably, the height of keriotheca can be 20~40mm, in this height, can ensure that it is anti-
The ability and compression strength of buckling can also ensure that sandwich plate is unlikely to the blocked up size for occupying sandwich plate baffle space.
Furtherly, it is equipped with functional component in the upper glue layer of the utility model and/or lower glue layer, which may include
Panel reinforcing rib, sound-proof material or ceramic bullet proof ball.Upper glue layer with a thickness of 5~15mm, lower glue layer with a thickness of 5~15mm.If
Glue-line is lower than 5mm, then is difficult adding structural elements inside it, influences integrally-built integrality, if bondline thickness is more than 15mm,
It is then affected to integrally-built specific strength specific stiffness, to influence the light weight effect of sandwich plate.
Further say, when the keriotheca of lateral honeycomb sandwich panel by least two layers of honeycomb core forms when, honeycomb core
Part or all of interlayer can be equipped with function element.Preferably, the thickness of the function element can be 15~30mm, the thickness range
Function element can satisfy its Functional Requirement and normalization facilitated to buy, and preferably may include bending resisting plate, ceramic wafer, soundproof plate
Or ceramic bullet proof ball, wherein the impact resistance of sandwich plate, and keriotheca can be effectively improved by being put into the penertration resistances such as ceramic wafer material
Ceramic wafer is wrapped up, potsherd can be effectively prevent to splash, the potsherd of reservation can continue to penertration resistance, improve sandwich plate
Capability of resistance to penetration.
The utility model has the advantages that compared with prior art, the remarkable advantage of the utility model are as follows: the transverse direction honeycomb sandwich panel is not only close
Small, light-weight, specific strength and specific stiffness height are spent, and vibration damping sound insulation and heat-proof quality are strong.
Firstly, compared to vertical cellular board, lateral buckling stability significantly increases by the way that keriotheca is laterally arranged, and
By simulating, verifying length and width and it is identical in quality in the case where, the lateral stiffness of lateral keriotheca is common vertical keriotheca
1.76 times, maximum load capacity is its 2.3 times, and the keriotheca being laterally arranged, and joint face is waveform when connecting with panel,
And then contact area is increased, adhesive strength is improved, it is smaller with contact surface between panel to solve legacy cellular sandwich plate, holds
The defect of easy degumming, method phase tensile strength significantly increase；
Secondly, functional material, In can be arranged in upper glue layer and/or lower glue layer, or in honeycomb core interlayer in the sandwich plate
Functional material is arranged in upper glue layer and/or lower glue layer, and the thickness that not only reduction sandwich plate is added in glue-line rationally utilizes space,
And it can further strengthen the sound insulation efficiency and/or heat-insulated efficiency of honeycomb sandwich panel；In honeycomb core interlayer, functional material is set,
Functional material is placed in the intermediate position of sandwich plate, not only simplifies difficulty of construction, reduces the thickness of lower glue layer, and
Can there is bigger space to place functional material, increase the thickness of functional material, further increase acoustical and thermal effect and
Capability of resistance to penetration, meanwhile, in the asymmetric setting functional material of honeycomb core interlayer, the bending resistance that can further increase sandwich plate is cut
Face coefficient improves anti-bending strength.
In addition, the method for preparing the honeycomb sandwich panel is easy, strong operability is at low cost, can be widely applied to ship
In the fields such as structure, building structure, panzer and ballistic structure.
