|Background and Objectives
The aim of this project is the development of a new group of "smart"
or intelligent materials, i.e. materials capable to follow small change
of external conditions in a preset way. The project also includes the elaboration
and technical realization of two industrial applications for such materials.
The relatively simple devices aimed to construct will demonstrate the new
materials potential for many other purposes.
The proposed materials have been synthesized
recently for the first time by both the Hungarian and Russian groups participating
in the present project. They represent a new type of composites consisting
of small magnetic particles dispersed within a highly elastic polymeric
matrix. Combination of magnetic and elastic properties leads to the appearance
of the unique ability of such materials to change their shape and mechanical
properties in an applied magnetic field in a reversible manner.
Highly elastic magnetic composites are quite
new. Understanding their behavior as a function of the composition, external
conditions and synthesis processes is still missing. Thus, one of the aims
of this project is the study of fundamental principles governing the preparation,
structure, and properties of these materials.
The preliminary studies show that among the
most appealing properties of the new composites are giant magneto-deformational
effect, high elasticity and quick response to magnetic field which open
new opportunities for using such materials for various applications, ranging
from magnetic coupling to peristaltic pumps, manipulators or "artificial
To demonstrate the engineering potential of
these new materials, two types of devices will be constructed, produced,
tested and advertised. First, we propose to develop a new type of seals
fundamentally different from those used before. In the simplest case the
sealing assembly includes a magnetoelastic strip and a permanent magnet.
They attract due to the magnetic forces. This ensures that due to high
elasticity of the proposed composites and good adhesion properties, the
strip of magnetoelastics will perfectly adopt the shape of the surface
to be sealed leading to excellent sealing.
Another straightforward application of the
magnetic composites which will be implemented in the course of this project
is based on their magnetic field dependent elastic modulus. Namely, we
plan to develop adjustable vibration dampers on the basis of the new materials
that are of high demand in many industrial applications.
The main results expected at the end of this project are the following:
The extensive investigation (by experimental methods, theoretical calculations
and computer simulations) of the properties of the magnetoelastic materials
depending on their composition and the processes of synthesis. The results
of these studies will permit to synthesise materials with optimum properties
for seals and vibration dampers working in several liquid and gaseous media
and under various mechanical stresses; the optimum technological parameters
will be established;
The development of the technology of low-cost industrial production of
highly elastic magnetic materials. The technologies developed will be adopted
by industry in the plant of the end-user;
The development of the devices based on the materials synthesised. It is
expected that the unique properties of these materials could find wide
applications in industry and they will be advertised for other Russian
