Embodiment 1

[0043] Such as figure 1 In the shown embodiment 1, a magnetic field-driven bistable structure includes a bistable laminated board 1 and a magnetically sensitive deformation driver 2 for driving the deformation of the bistable laminated board 1, and the magnetically sensitive deformation driver 2 is bonded The magneto-sensitive deformation driver 2 is mainly fixed on the edge of the bistable laminate 1, and the magneto-sensitive deformation driver 2 is set as a magneto-rheological elastomer driver.

[0044] In this technical solution, the bistable laminated board 1 has bistable characteristics, it has multiple stable forms, and it does not require external force to maintain the form, and as Figure 5 As shown, the magnetically sensitive deformation driver 2 will bend to one side under the action of an external magnetic field to generate a bending moment, and the bending moment will generate a sudden force that promotes the transition of the bistable laminate 1 from the first st...

Embodiment 2

[0048] The technical solution of embodiment 2 is basically the same as the technical solution of embodiment 1, and the difference is that: the bistable laminated board 1 includes a double-layer layered material, the layered material is laid orthogonally, and the layered material is orthogonal Orthogonal laying of various special-shaped materials and ply materials is conducive to generating residual stress after heating and curing, so that the obtained bistable laminated board 1 has two stable states. Here, the layup material is set to T700 carbon fiber epoxy resin, and the thickness of a single layer is 0.03mm. The bistable laminate 1 needs to be deformed and converted between two stable states. T700 carbon fiber epoxy resin prepreg has good toughness, Make the bistable laminated board 1 difficult to break.

Embodiment 3

[0050] A method for manufacturing a magnetic field-driven bistable structure, comprising the following steps:

[0051] Step 1: Lay two lay-up materials orthogonally, here the lay-up material is T700 carbon fiber epoxy resin, and then use the autoclave molding process to complete the production of the bistable laminate 1, that is, the lay-up is cured under high temperature and high pressure, So that it produces two steady states;

[0052] Step 2: Mix the flexible matrix material with the magnetic particles 202 to obtain a mixture, then place the mixture in a vacuum drying oven to evacuate, then place the mixture in a sealed mold 3 and cure it under a uniform magnetic field to complete the magnetically sensitive deformation driver 2 Manufacture, that is, the manufacture of the magneto-rheological elastomer driver is completed;

[0053] Step 3: Bonding the magnetically sensitive deformation driver 2 on the bistable laminated board 1 through an adhesive to complete the fabricatio...

Description

technical field [0001] The invention relates to the technical field of intelligent deformable structures and composite materials, in particular to a magnetic field-driven bistable structure and a manufacturing method thereof. Background technique [0002] Composite bistable refers to a structure that has two deformation capabilities and can maintain a stable state without continuous energy input after deformation. It is precisely because of this characteristic that it has great application potential in fields such as deformable wings, unfolded structures, and deployable solar panels. With the development of aviation and aerospace industries, higher requirements are put forward for the deformation ability of deformable structures. The intelligent driving method of the bistable structure mainly uses shape memory alloys, piezoelectric materials, etc. at present. However, because the response speed of the existing driving method is slow and will have a certain influence on its...
