Abstract

The invention provides a rapid prototyping method of a magnetorheological composite body, in which a type I magnetorheological elastic material, a type II magnetorheological elastic material, a type I magnetorheological elastic material and a magnetorheological viscoplastic material are used in any The required forms are combined to prepare a magnetorheological composite with non-uniform physical properties. The mixed 3D printing of magnetorheological materials with different physical states and mechanical properties is realized, and flexible digital structure design can be carried out. The forming of solid magnetorheological elastic materials and the packaging of semi-solid magnetorheological viscoplastic materials can be completed at one time. By virtue of the different response characteristics of the mechanical properties of different types of magnetorheological materials under an external magnetic field, it can meet the requirements of complex operating conditions that require magnetorheological materials with different mechanical properties in different positions. The composite prepared by the method of the invention can be used as various functional elements and structural elements such as shock absorbing and damping elements or soft molds for plate forming, and has good performance; meanwhile, the method of the invention has short period, simple process and low cost.

Description

technical field

[0001] The invention belongs to the technical field of composite material forming, and in particular relates to a rapid forming method of a magnetorheological composite body. Background technique

[0002] At present, magnetorheological fluid, as a smart material, is considered to be a new smart material with the most development potential in the field of material science because of its unique magnetorheological effect and good rheological properties. At present, magnetorheological fluids have been widely used in dampers, shock absorbers, magnetorheological polishing and magnetorheological sealing. The magnetorheological effect refers to the addition of a magnetically conductive, non-soluble medium to the fluid. Under the action of an external magnetic field, the rheological properties of the fluid undergo a sudden change, rapidly solidify and lose fluidity, and the solidification process is transiently reversible.

[0003] In order to further develop researc...
