When the functional prepreg blocks made of the same material are spliced to form the layering structure, the shape and the size of each functional prepreg block can be cut according to the needs, and then the functional prepreg blocks can be mutually butted/lapped, so that the complex layering structure can be realized.
Of course, functional prepreg blocks with different materials/functions can be adopted for block paving and then splicing. The composite lay-up structure thus formed may combine different functionalities.
In some examples of the application, the composite lay-up method may further include steps S2100 to S2300 as follows, see fig. 2.
Step S2100, preparing a first functional prepreg block and a second functional prepreg block; wherein the first functional prepreg and the second functional prepreg have different functions;
Step S2200, paving the first functional prepreg block at a first position and paving the second functional prepreg block at a second position according to preset paving information;
Step S2300, splicing the first functional prepreg block and the second functional prepreg block to form a composite material layering structure.
Wherein the first location and the second location should have overlapping areas so that mutual splicing/overlapping between prepreg blocks can be achieved to form a whole.
According to the composite material paving scheme provided by the embodiment of the application, two different functional prepreg blocks can be spliced to form a paving structure, namely, one functional prepreg and the other functional prepreg are subjected to heterogeneous material lap joint paving design, so that the same paving structure can have two different functions, and the accurate control of the paving positions of the different functional prepreg blocks can further realize the manufacture of different material combinations, complex paving structures and functional characteristics of products.
The composite material layering method provided by the embodiment of the application can be used for performing complex layering of complex structures and heterogeneous materials, so that the realizability of complex-structure and functional composite material products is improved. In addition, the whole layering method is simple to implement, easy to operate and control, and the product yield can be improved.
The composite material layering method provided by the embodiment of the application can realize accurate control of the positions, the laying directions, the laying angles and the like of prepreg blocks with different functions on a layering structure based on a block paving design.
In the step S2200, the laying specifications of the single prepreg block, including the specification information such as the size, the material, the fiber surface density, the laying angle, etc., may be split layer by layer and block by block according to the pre-designed preset laying information.
Wherein the first functional prepreg block and the second functional prepreg block are cut in advance to form a desired size and shape.
It should be noted that other positions may be provided on the same layer of the ply structure, for laying prepreg blocks with different functions.
In some examples of the application, the first functional prepreg block has electromagnetic shielding properties and the second prepreg block is permeable to electromagnetic waves.
According to the above example, on the layup structure, the first functional prepreg block may shield electromagnetic waves, and the second functional prepreg block may transmit electromagnetic waves, the functions of the two being different. When the laminate structure is used to make, for example, a housing of an electronic device, all antennas in, for example, the electronic device can be arranged in an area corresponding to the second functional prepreg block, so that the communication performance of the electronic device is not affected. In addition, the application can directly prepare the needed shell and form the material capable of transmitting electromagnetic waves at the antenna position based on the block paving.
The application is based on the design of block paving, and can conveniently manufacture curved surface shells and the like.
In some examples of the application, the first functional prepreg block consists essentially of carbon fibers and a resin matrix; the second functional prepreg block is mainly composed of an electromagnetic wave-penetrable material and resin, wherein the electromagnetic wave-penetrable material comprises glass fiber or aramid fiber; wherein the resin matrix is a thermosetting resin material.
Wherein, carbon fiber is as the reinforcing material, and the reinforcing material and the matrix form the first functional prepreg block. The carbon fiber is selected as the main material for manufacturing the shell of the electronic product, so that the aims of thinning and weight reduction can be achieved. However, the carbon fiber composite material has a blocking or weakening effect on antenna signals, and has technical challenges in application to AR, VR and mobile phone shells. Thus, a second functional prepreg block is also introduced into the lay-up structure, which is in combination with another function.
The carbon fiber composite material can be a composite material formed by mixed weaving of carbon fiber, glass fiber, carbon fiber, aramid fiber and the like.
Wherein the second functional prepreg contains a material that is transparent to electromagnetic waves, such that the second functional prepreg does not obstruct or impair antenna signals.
Wherein the matrix is a thermosetting resin material, and the thermosetting resin is subjected to chemical reaction under heating, cross-linking, curing and forming. Thermosetting resins have high heat resistance and are not easily deformed after being pressed.
Wherein, in preparing the first functional prepreg block, the carbon fiber can be unidirectional or in a fabric form, and then is compounded with a thermosetting resin matrix to prepare the prepreg. For example, the first functional prepreg is a 3K twill carbon fiber prepreg.
In the preparation of the second functional prepreg block, corresponding fibers can be made into a fabric or unidirectional tape form, and thermosetting resin with the same or similar curing characteristics as the first functional prepreg block is used for preparing the prepreg.
In some examples of the application, the thermosetting resin material includes at least one of epoxy resin, epoxy vinyl resin, phenolic resin, and polyurethane resin.
In some examples of the present application, the mass ratio of the resin matrix in the first functional prepreg block and the second functional prepreg block is 28% to 45%.
For example, the first functional prepreg block and the second functional prepreg block may each be made of epoxy resin, and the mass ratio of the epoxy resin may be 28%, 35%, 40%, 45%, or the like.
The ratio of the resin matrix in the functional prepreg block can be adjusted according to actual needs, and the above range is a relatively common range. Of course, the above range may be appropriately adjusted as needed, and the present application is not limited thereto.
In some examples of the application, the second location is a removed area or partial replacement of the material of the first location.
That is, a first location may be designed prior to layup, then a second location may be formed on the first location in a subtractive manner as desired, and then a second functional prepreg block may be filled in the second location formed.
Of course, the first position and the second position or more may be separated directly in the ply structure, which is not limited in the embodiment of the present application.
In some examples of the application, the composite lay-up has an overall thickness of 0.15mm to 1.2mm.
The prepared composite material layer structure can be used for directly manufacturing a shell of an electronic product, so that the whole thickness of the composite material layer is not easy to be too thick in order to realize the thinning and the light weight of the shell, and the range can be controlled. For example, the thickness of the composite material layering structure is lower than 0.15mm, the strength of the electronic shell cannot be ensured, and the rejection rate of products is increased. If the thickness of the composite material ply structure is higher than 1.2mm, the weight and thickness of the outer shell are increased, and the requirements of thinning and light weight cannot be met.
In some examples of the present application, the composite lay-up method further includes the following steps S3100 to S3400, see fig. 3:
Step S3100, paving the first functional prepreg block on a first paving transfer plate;
Step S3200, controlling the first paving transfer plate to move so as to transfer and lay the first functional prepreg on the paving substrate, and tightly laying the first functional prepreg on the first position;
step S3300, paving the second functional prepreg on a second paving transfer plate;
Step S3400, controlling the second ply transfer board to move so as to transfer and lay the second functional prepreg on the ply substrate, and tightly laying the second functional prepreg on the second position.
The composite material layering method provided by the embodiment of the application can also carry out semi-automatic or automatic paving by means of mechanical equipment, thereby greatly improving the production efficiency and avoiding deviation caused by artificial paving. Meanwhile, the stability of the layering quality is improved, and the manual misoperation is avoided.
The composite material layering method provided by the embodiment of the application can reduce the product quality defect probability, improve the manufacturing process stability and the dimensional accuracy, reduce the quality discreteness and meet the high-quality and high-accuracy manufacturing requirements.
In step S3100, the release paper and the PE film on the surface of the first functional prepreg block need to be removed, and then the first functional prepreg block is laid on the first layup transfer board. Wherein, the release paper and the PE film are both raw material protective films.
In the step S3200, the first layup transfer board may move with the first functional prepreg block, and the movement of the first layup transfer board may be controlled, for example, by a special movement mechanism, so that the first layup transfer board moves to a specified position and then is laid.
In the step S3200, compacting by a pressing mechanism is also required to achieve accurate and tight paving of the specific position of the first functional prepreg block. Specifically, a certain force is applied to the first layup transfer board side, so that the first functional prepreg block can be adhered to the layup substrate, and at this time, the first layup transfer board is separated from the layup substrate, so that the first functional prepreg block is laid on the layup substrate.
In the step S3400, the laying substrate may be switched between a plurality of stations, for example, by a sliding rail, and the second laying transfer board may move with the second functional prepreg block, and at this time, the movement of the second laying transfer board may be controlled by a movement mechanism so as to move to a specified position. And compacting by a pressurizing mechanism, so that the specific position of the second functional prepreg block is accurate, and compact and paving is realized. Specifically, a certain force is applied to the second layup transfer board side, so that the second functional prepreg block can be adhered to the layup substrate, and at this time, the second layup transfer board is separated from the layup substrate, so that the second functional prepreg block is laid on the layup substrate.
And after all the layers are paved, a laminated structure can be obtained, and at the moment, the laminated structure and the paving substrate can be separated through an ejection mechanism, so that the laminated structure to be subjected to hot press molding is obtained.
In some examples of the application, in the first position, the first functional prepreg block is stacked in multiple layers; and/or, in the second position, the second functional prepreg block is stacked into a plurality of layers.
For example, the first functional prepreg block may be stacked in two or more layers, and the second functional prepreg block may be stacked in two or more layers.
In some examples of the present application, the composite lay-up structure is a staggered splice, and the first functional prepreg block and the second functional prepreg block are laid up according to a preset distance.
According to another embodiment of the present application, there is provided a composite lay-up structure prepared by the composite lay-up method described above.
In some examples of the application, the composite lay-up structure is comprised of at least one functional prepreg spliced to one another.
For example, the composite layup may be comprised of a plurality of first functional prepreg blocks that are butted/lapped with each other.
