Description
Technical field
The present invention relates to a kind of bidirectional crossed ripple sandwich, which can be used as structural member and navigates applied to aviation
It, vehicle, naval vessel field, also can be used as panel application in building field.
Background technique
Multi-functional composite construction has the series of advantages such as high specific strength and specific modulus, designability, has obtained more next
More extensive concern and application are related to national defence, military affairs, vehicle, naval vessel, submarine, building, bridge etc..Ripple sandwich is made
It for a kind of compound structure for new residence form, is made of two pieces of upper and lower panels and intermediate ripple laminboard layer, material used in core
Ripple struction form is geometrically being presented in material.The panel and laminboard layer of ripple sandwich can be by bonding agent or welding etc. even
The mode of connecing links together, and can also pass through other technological formings.Ripple sandwich improves cross sectional moment of inertia by core,
To reach ideal structural mechanical property.Traditional ripple sandwich generally has the core of unidirectional corrugated form, face
Interior mechanics performance has certain directionality, has the mechanical property in a direction weak, and causing the structure to be applied has limitation, it is difficult to
It adapts to the higher engineering application requirement of mechanical property requirements.
Summary of the invention
In view of this, the sandwich core is two-way company the present invention provides a kind of bidirectional crossed ripple sandwich
Continue the intersection of ripple and partially overlap, is remarkably improved the mechanical properties such as transverse direction and the shearing resistance of sandwich structure.
A kind of bidirectional crossed ripple sandwich, the sandwich are made of top panel, lower panel and core, the core
Positive and negative surface all have according to ranks rule arrange pit, the center line of pit takes thickness to core along the ranks of edge
Section, core adjacent side are that both direction is identical and continuous ripple struction, the ripples of two sides joint simultaneously
In wave crest or trough;Top panel and lower panel are separately fixed at the upper and lower surface of core.
Further, the material of the top panel, lower panel and core does not select simultaneously or simultaneously homogeneous material or compound
Material.
Further, the top panel, lower panel and core with a thickness of equal thickness.
Further, the top panel, lower panel and core with a thickness of not equal thickness.
Further, the corrugated cross-section shape of the core is trapezoidal or rectangle.
Further, the ripple angle of two sides of the core can be 100~90 °.
Further, the bidirectional crossed ripple sandwich is made of integrally formed or multiple moulding process.
Further, the bidirectional crossed ripple sandwich is slab construction or curved-surface structure.
The utility model has the advantages that
Bidirectional crossed ripple struction is presented in core of the invention in face, has the mechanical property significantly increased.Due to it
Have many advantages, such as high specific strength, specific modulus, designability, can be widely applied to the civil fields such as vehicle, building, can also be applied to
The military uses such as aerospace, submarine naval vessel.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1 and 2, the present invention provides a kind of bidirectional crossed ripple sandwich, the sandwich is by above
Plate 1, lower panel 3 and core 2 form;
As shown in attached drawing 3,4 and 5, the positive and negative surface of core 2 all has the pit arranged according to ranks rule, and pit is ladder
Shape, the bottom surface of trapezoidal pit are trapezoidal short side, and the top of trapezoidal pit is trapezoidal long side;Along edge, ranks upper trapezoid is recessed
The center line in hole takes thickness x cross sectional to core, and the whole core 2 after interception is in rectangle, and 2 adjacent side of core is that both direction is complete
Exactly the same and continuous trapezoidal ripple struction, the trapezoidal ripple of two sides are in the wave crest or wave of trapezoidal ripple in joint simultaneously
Paddy;Top panel 1 and lower panel 3 are separately fixed at the upper and lower surface of core 2.
The material of top panel 1, lower panel 3 and core 2 is the isotropic materials such as stainless steel, ABS resin.
The corrugated cross-section of core 2 is the shapes such as rectangle, the ripple angle in the 2 face direction Nei Liang of core can be 90 ° or its
Its angle.
The thickness of top panel 1, lower panel 3 and core 2 can be equal thickness, be also possible to not equal thickness.
Core 2 and top panel 1 and lower panel 3 can be integrated molding, be also possible to the connection types connection such as welding, splicing
It forms.
The bidirectional crossed corrugated surface is plane or curved-surface structure.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
