Material is the piezoelectric material as made of two or more Material claddings.Common piezo-electricity composite material be by piezoelectric ceramics (such as PZT or
Lead titanates) or piezoelectric monocrystal and polymer (such as rubber or epoxy resin) composition.Influence the factor of piezo-electricity composite material characteristic
There are connectivity, characteristic, the volume occupation rate of each material and the shape and size of two kinds of materials etc..The connectivity of composite material is anti-
The mode that each constituent element interconnects in three-dimensional space itself is reflected.Connectivity determines electric field in composite material, magnetic field and stress
Distribution situation, thus have a great impact to performance.In the composite, it is isolated such as certain material by other materials, then claims
This kind of material is 0 connection；As certain material on one, two or 3 direction of three-dimensional space self connection, then be referred to as
1 connection, 2 connection and 3 connection.For example, piezoelectric ceramics powder is dispersed in formation 0-3 connectivity Piezoelectric anisotropy material in rubber polymer
Material, the dispersion of piezoelectric ceramics column form 1-3 type piezo-electricity composite material in the epoxy.
1-3 type piezo-electricity composite material be arranged in parallel in the polymer of three-dimensional communication by one-dimensional piezoelectric ceramics column and
The two-phase piezo-electricity composite material with piezoelectric effect constituted.1-3 type piezo-electricity composite material due to overcoming to a certain extent
Defect of the pure piezoelectric ceramics in terms of intensity, brittleness, while it is significantly increased in longitudinal coefficient of coup, therefore becomes current
Most study, a kind of most deep, most widely used piezo-electricity composite material.
Currently, domestic common its piezoelectric ceramics array element of 1-3 type piezo-electricity composite material energy converter is square, it is to pass through
To the mode of the horizontal and vertical cutting of piezo ceramic element, the then filled polymer in gap, in array element size also by
Some limitations of cutting equipment.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of triangle array element Piezoelectric anisotropy material
Expect energy converter preparation method.
The object of the present invention is achieved by the following technical solutions.A kind of triangle array element piezo-electricity composite material transducing
Device preparation method, energy converter are made of triangle piezo-electricity composite material, and energy converter can have better aspect ratio and work
Bandwidth.When the triangle piezo-electricity composite material makes, horizontal, vertical and 45° angle direction is carried out to piezoelectric element and is carried out
It cuts three times, the array element spacing in 45° angle direction is both horizontally and vertically array element spacingTimes, cut the piezoelectricity of formation
Ceramics pole is as triangle array element.
Polymer is perfused in the gap of piezoelectric element, surface is ground after solidification, passes through magnetron sputtering or steaming
The mode of plating carries out Electrode treatment to surface, then carries out water tight enclosure to energy converter.
It is carried out three times the invention has the benefit that carrying out horizontal, vertical and 45° angle direction to piezoelectric element when production
Cutting, piezoelectric ceramics column improve its oscillation crosswise to further improve the aspect ratio of piezoelectric ceramics column for triangle array element
Influence.Manufacture craft of the present invention is simple, and compared with square composite material, performance is improved；The energy converter can be applied to
High frequency imaging sonar, undersea detection and marine engineering implementation etc..
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Description of symbols: piezoelectric element 1, polymer 2.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
As shown in Figure 1, this triangle array element piezo-electricity composite material energy converter preparation method, energy converter uses triangle pressure
Composite production, energy converter can have better aspect ratio and bandwidth of operation.The triangle piezo-electricity composite material
When production, vertical and 45° angle direction horizontal to piezoelectric element progress is cut three times, and the array element spacing in 45° angle direction is
Both horizontally and vertically array element spacingTimes, the piezoelectric ceramics column of formation is cut as triangle array element, is further increased
Composite material aspect ratio.Polymer 2 is perfused in the gap of piezoelectric element 1, surface is ground after solidification, is splashed by magnetic control
The mode penetrated or be deposited carries out Electrode treatment to surface, then carries out water tight enclosure to energy converter.
Specific embodiment is divided into following steps:
Step 1: the design of array element
Working frequency as needed, the thickness of design of Simulation array element avoid it strong using the thickness vibration of array element
Coupled vibrations region controls the resonance frequency of array element by adjusting lateral dimension, and lateral dimension is less than thickness direction, battle array as far as possible
The aspect ratio of member is greater than 2 or more, and a length of 2mm × 2mm of right side of the triangle, piezoelectricity array element uses PZT4 material.
Step 2: the cutting of piezoelectric element (ceramic component)
The suitable clamping mold of design, the piezoelectric ceramic wafer of φ 60mm is cut, and progress horizontal direction first is cut
It cuts, array element spacing 2.4mm, then cutting gap 0.4mm is rotated by 90 °, carry out vertical direction cutting, and array element spacing 2.4mm is cut
Slot gap 0.4mm rotates 45 °, array element spacing 1.69mm again after cutting.
Step 3: perfusion polymer
Element is placed in perfusion mold, the filled polymer in the gap of array element is wanted in the filling process of polymer
Vacuumize process is carried out to polymer latex first, prevents concealing for air bubble, meanwhile, when perfusion also need to vacuumize it and
Heat treatment, to guarantee to be each filled with polymer between each array element.
Step 4: grinding and Electrode treatment
The working frequency designed in order to obtain carries out the inner surface and the outer surface to the triangle piezo-electricity composite material being perfused
Grinding, its thickness is milled to design size, then to surface carry out cleaning treatment, by magnetron sputtering or vapor deposition in the way of
Silver layer is made, to obtain the anode and cathode of piezo-electricity composite material.
Step 5: the processing of energy converter watertight
To meet the use and performance test of transducer array in water, watertight processing is carried out to its surface, in outer lateral irrigation
The waterproof material of one layer of 4mm thickness of note, material are polyurethane.
The cable that the positive and negative polarity wire of energy converter passes through band shielding is drawn after perfusion, cable and energy converter metal back seat it
Between connected by watertight cable head.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
