Description
Technical field
The present invention relates to a kind of sandwich structure and preparation method thereof, and in particular to a kind of hollow dot matrix-honeycomb of all-metal is mixed
Miscellaneous sandwich structure and its interlocking preparation method, it is adaptable to the field such as Aero-Space, ship ocean, under water antiknock, transportation building.
Background technology
In recent years, increasing high-performance energy-absorbing material (structure) is always research focus.And loose structure has use concurrently
The features such as lightweight and effective energy-absorbing, thus high-performance energy-absorbing medium is widely used as, they are often used as Sandwich Beam
Core absorbs from outside impact energy and explosion energy.Loose structure includes random bubble and periodicity loose structure,
The latter includes the structural material such as honeycomb and minute yardstick truss dot matrix.
Honeycomb, as a kind of ultralight loose structure of sequential 2 D, is that world today's manufacturing technology is most ripe, application field
Most wide light structures, its mother metal can be any one such as polymer, metal, ceramics or composite.They are a kind of power
The material of property anisotropy is learned, generally there are very high strength and stiffness on the direction outside face.As can be seen here, honeybee
Nest not only has the advantages that lightweight but also excellent in mechanical performance.Especially for aluminium honeycomb, scholars have carried out substantial amounts of experiment
And theoretical research, find its compression response in a thickness direction with longer and fluctuation very little plateau stress, be it is a kind of compared with
It is particularly true to density area in low phase for efficient energy-absorbing material.But be not in high relative density regional cellular structure
Optimal endergonic structure.In addition, most of experimental study for honeycomb cutting performance be confined to relative density for 8% with
Under structure, and face core unsticking this catastrophic failure shape is observed in the shearing test of higher relative density fuse
Formula.
And cellular dot matrix truss material may be replaced as future, except structural strength is suitable with honeycomb, its inside
High porosity is easier to integrated multifunction characteristic.But solid truss lattice structure post-buckling residual strength is relatively low, is not good
Good energy-absorbing material.The appearance of hollow truss dot matrix compensate for that this is not enough, because it has higher secondary area moment, can be with
The common post-buckling ruckbildung of low-density truss structure is relieved, makes core bar that there is higher post-buckling residual strength, because
And with excellent ratio energy absorption characteristics.And hollow truss dot matrix is easy to carry out many geometric parameter collaboration optimizations to realize that structure is held
Loading capability is maximized.
It is well known that under impact loading, the intensity of material is to rely on impact speed, and stable inertia effect
The energy-absorbing capacity of energy lift structure.Therefore, it is very necessary to obtain basic material quasistatic energy absorption performance data.And
As a kind of new topological structure, the architectural characteristic and excellent energy that hollow pyramid dot matrix truss has high-strength light concurrently are inhaled
Receipts ability, increasingly by the extensive concern of domestic and international researcher.Under the effect of concora crush load, hollow pyramid dot matrix truss knot
The unit mass energy absorption ability of structure is apparently higher than other core structures.But, the unit of hollow pyramid dot matrix truss structure
Volume energy absorption ability is suitable with other core structures, wherein energy-absorbing effect is inferior to honeycomb under low impact loading.
But under high impact loads effect, compared to other topological structures, the unit mass energy-absorbing of hollow pyramid dot matrix truss structure
All it is optimal with unit volume energy absorption ability.Equally, under shear loads, the energy-absorbing water of hollow pyramid dot matrix structure
Pingyuan County is higher than porous materials such as open cell metallic foams.
