The buildings such as happy place heat-insulated, sound insulation building materials use.
The design of composite property is always a big advantage of composite, and cellular composite material is no exception.Honeybee
Nest composite can change the performance of cellular board by changing the size of honeycomb core and upper lower thin sheet.But for honeycomb
The design of plate anti-acoustic capability, it is always a problem.The principle of cellular board noise reduction sound insulation is sound transmission to honeycomb core wallboard
When, sound wave can come and go vibration in countless cellulor spaces, this equivalent to adding a lot of layer sound insulating sheet materials, sound energy loss into
Mechanical energy and heat energy, reach noise reduction, and noise reduction is related to honeycomb shape, size.
Present cellular material, such as regularly arranged regular hexagon cellular material, often can only be in a certain frequency separation
Sound have noise reduction, it is and poor to other frequency acoustic noise reduction；More circumscribed circular cellular material, changes
Become the radius of a circular honeycomb, other all circular configurations will change, and change and have no rule, its property
The design and manufacture of energy are inconvenient.
Utility model content
The utility model main purpose is to solve the above problems and deficiency, there is provided a kind of anti-acoustic capability design is easy, adds
The convenient cellular composite material plate of work and its honeycomb core structures, this cellular composite material plate possess powerful resistance to compression, bending resistance energy
Power, while the advantages that damping, heat-insulated and extremely strong weatherability, anti-acoustic capability design is easier.
The technical solution of the utility model；A kind of in order to solve the above technical problems, noise reduction knot of regular hexagon cellular material
Structure, including upper and lower carbon fiber layer plywood, honeycomb core composition；It is characterized in that：Upper and lower carbon fiber layer plywood is covered in honeycomb core two
End, is glued between honeycomb core；Honeycomb core is made up of regular hexagon honeycomb and circular honeycomb.
The utility model honeycomb core is made up of aluminum alloy materials, and honeycomb core is based on regular hexagon honeycomb, circular honeycomb
It is evenly distributed between regular hexagon honeycomb, the circular cellular center of circle is in the cellular public rib of the adjacent regular hexagon in part three
Bian Shang, the circular arc that circular honeycomb is divided into 3 sections 120 ° are distributed in three regular hexagons.
Further, the laminate up and down is made up of carbon fiber, and laminated plate thickness can change.
Further, when producing honeycomb core, mould is changed, the cellular radius of circle can change.Circular honeycomb half
The scope that footpath changes is within the regular hexagon honeycomb length of side.
Further, when producing honeycomb core, mould is changed, the cellular number of circle can change.Justified by changing
The cellular size of shape, number, it can not only design the anti-acoustic capability of the cellular composite material of this structure, moreover it is possible to it is strong to design its
Degree, rigidity property.
Further, when producing honeycomb core, mould is changed, the thickness of the honeycomb wallboard can change.Honeycomb wallboard
Thickness can change；Upper and lower carbon fiber layer plywood is made up of carbon fiber epoxy woven cloth, the thickness of plate, carbon fiber laying side
Formula can change；When producing honeycomb core, the thickness of honeycomb core can change.
Further, when producing honeycomb core, mould is changed, three pieces of regular hexagon honeybees at the circular honeycomb and circular honeycomb
The height of nest wallboard can change.The height of three pieces of regular hexagon honeycomb wallboards can change at circular honeycomb and circular honeycomb,
A kind of form is that three pieces of regular hexagon honeycomb wallboard one end maintain an equal level with honeycomb core end face at circular honeycomb and circular honeycomb, the other end
It sink；Second of form be at circular honeycomb and circular honeycomb three pieces of regular hexagon honeycomb wallboard both ends not with honeycomb core end face
Maintain an equal level, both ends are all sunk certain depth.
Further, when producing honeycomb core, the thickness of the honeycomb core can change.
The beneficial effects of the utility model are：
（1）This cellular composite material plate subtracts with the powerful resistance to compression as legacy cellular material, bending resistance
Shake, heat-insulated and extremely strong weatherability, anti-acoustic capability.
（2）Performance design is easy, by changing circular cell radius and circular honeycomb proportion, can expand noise reduction frequency
Rate scope and noise reduction；By changing honeycomb other sizes parameter, thus it is possible to vary other performances of cellular composite material plate.
