specific example 1

[0041] Firstly select the elemental components of Ni-Mn-Ga: nickel, manganese, and gallium, and smelt them at low temperature in a vacuum to alloy the elements; slowly raise the temperature to 1450°C for homogenization for 4 minutes, and cool naturally after ingot casting; after cooling, mechanically crush to The small pieces were then vibrated and ball milled for 12 hours, and powders of different sizes were sieved out at intervals to obtain Ni-Mn-Ga powder particles. Then weigh and mix 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 solution Stir the beaker at a speed of 90r / min to disperse the Ni-Mn-Ga powder evenly in the beaker; place the beaker in an ultrasonic cleaner to disperse the particles and remove air bubbles, and slow down the stirring speed to about 60r / min. The process lasts about 10 minutes. Slowly and evenly pour ...

[0043] Firstly select the elemental components of Ni-Mn-Ga: nickel, manganese, gallium, smelt in vacuum at low temperature to alloy the elemental substances; slowly raise the temperature to 1450°C and homogenize for 5 minutes, then cool naturally after casting ingots; after cooling, mechanically crush to The small pieces were then vibrated and ball milled for 24 hours, and powders of different sizes were screened out at intervals to obtain Ni-Mn-Ga powder particles. Then weigh and mix bisphenol A diglycidyl ether epoxy resin (E51) and tetraethylenepentamine at a mass ratio of 100:15, stir for 1 minute to fully mix the two, and then slowly introduce the powder into the mixed solution Stir the beaker at a speed of 120r / min to disperse the Ni-Mn-Ga powder evenly in the beaker; place the beaker in an ultrasonic cleaner to disperse the particles and remove air bubbles, and slow down the stirring speed to about 70r / min. The process lasts for about 20 minutes. Slowly and evenly pour...

[0045] Firstly select the elemental components of Ni-Mn-Ga: nickel, manganese, gallium, melt at low temperature in vacuum to alloy the elemental substances; slowly raise the temperature to 1450°C and homogenize for 7 minutes, then cool naturally after casting ingots; after cooling, mechanically crush to The small pieces were then vibrated and ball milled for 24 hours, and powders of different sizes were screened out 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 1.4 minutes to fully mix the two, and then slowly introduce the powder into the mixing container Stir the beaker of the liquid at a speed of 110r / min to disperse the Ni-Mn-Ga powder evenly in the beaker; place the beaker in an ultrasonic cleaner to disperse the particles and remove air bubbles, slow down the stirring speed to about 65r / min, This process lasts about 15 minutes....

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...
