Example

[0040] Specific example 1:

[0041] First, select the element elements of Ni-Mn-Ga: nickel, manganese, and gallium, and smelt them in vacuum at low temperature to alloy the elements; slowly increase the temperature to 1450°C and homogenize for 4 minutes, and then cool down naturally after casting; after cooling, it is mechanically broken to The small pieces were subsequently vibrated and ball milled for 12 hours, and powders of different sizes were sieved at intervals to obtain Ni-Mn-Ga powder particles. Then weigh and mix the selected bisphenol A diglycidyl ether epoxy resin (E51) and tetraethylenepentamine at a mass ratio of 100:15, stir for 2 minutes to fully mix the two, and then slowly introduce the powder into the mixed liquid The beaker is stirred at a speed of 90r / min to uniformly disperse the Ni-Mn-Ga powder in the beaker; the beaker is placed in an ultrasonic cleaning machine to disperse particles and remove bubbles, and slow down the stirring speed to about 60r / min. T...

[0044] Specific example 3:

[0045] First, select the element elements of Ni-Mn-Ga: nickel, manganese, and gallium, and smelt them in vacuum at low temperature to alloy the elements; slowly increase the temperature to 1450°C and homogenize for 7 minutes. After casting the ingot, cool naturally; after cooling, it is mechanically broken to The small pieces were subsequently vibrated and ball milled for 24 hours, and powders of different sizes were sieved at intervals to obtain Ni-Mn-Ga powder particles. Then weigh and mix the selected bisphenol A diglycidyl ether epoxy resin (E51) and tetraethylenepentamine at a mass ratio of 100:15, stir for 1.4min to fully mix the two, and then slowly introduce the powder into the container. The beaker of liquid is stirred at a speed of 110r / min to uniformly disperse the Ni-Mn-Ga powder in the beaker; the beaker is placed in an ultrasonic cleaning machine to disperse particles and remove air bubbles, slow down the stirring speed to about 65r / min,...

Abstract

The invention provides a novel Ni-Mn-Ga resin based composite material and a preparation method of the Ni-Mn-Ga resin based composite material. The composite material is prepared by the following design scheme and process: firstly, preparing Ni-Mn-Ga powder particle as functive, stirring E51 epoxy resin matrix with a curing agent in order to mix uniformly, adding Ni-Mn-Ga powder particle, stirring completely, arranging a beaker in an ultrasonic cleaning machine during the whole process, in order to disperse particles and remove bubbles; slowly and evenly pouring turbid liquid in a mold, standing under normal temperature, curing the turbid liquid, and finally obtaining a composite material test piece, wherein the curing agent used in the epoxy resin is tetraethylenepentamine. The novel particle composite material provided by the invention has excellent mechanical property and damping performance.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a novel particle composite material, in particular to a design scheme and a preparation method of a functional metal particle resin-based composite material. Background technique [0002] Ferromagnetic shape memory alloys are a new class of smart materials discovered in the last decade. Not only has the characteristics of large strain and high driving force of ordinary shape memory alloys, but also has the characteristics of fast response and high efficiency. Compared with other smart materials, ferromagnetic shape memory alloys not only have the ability to phase with shape memory alloys under the magnetic field Ni-Mn-Ga is a typical representative of Ni-Mn-Ga, which has specific, large output strain and stress, high energy density, high frequency response and precisely controllable characteristics comparable to piezoelectric materials. However, Ni-Mn-Ga alloys have de...
