Characterisation of magnetorheological elastomer materials for the core of smart sandwich structures

Characterisation of magnetorheological elastomer materials for the core of smart sandwich structures
Characterisation of magnetorheological elastomer materials for the core of smart sandwich structures
This paper presents results from tests carried out on the effect of magnetorheological elasotmer (MRE) material make-up, processing features and cure under the magnetic field with respect to the volume of iron particles on shear properties. As core material of smart sandwich structure, performance characterization of the smart function in terms of curing time, air bubble effect and the volume of iron particles of MRE is explored. The purpose of this paper is to find out storage shear modulus and loss factor of MRE specimens and to explore the ideal volume fraction of iron particles, curing time under magnetic field and air bubble effect to maximize shear modulus changes. Since shear properties of MRE changes dominantly in small strain ranges, MRE is shown as being a core material of a sandwich beam which achieves adjustable stiffness.

Abstract

This paper presents results from tests carried out on the effect of magnetorheological elasotmer (MRE) material make-up, processing features and cure under the magnetic field with respect to the volume of iron particles on shear properties. As core material of smart sandwich structure, performance characterization of the smart function in terms of curing time, air bubble effect and the volume of iron particles of MRE is explored. The purpose of this paper is to find out storage shear modulus and loss factor of MRE specimens and to explore the ideal volume fraction of iron particles, curing time under magnetic field and air bubble effect to maximize shear modulus changes. Since shear properties of MRE changes dominantly in small strain ranges, MRE is shown as being a core material of a sandwich beam which achieves adjustable stiffness.
