Abstract

The article focuses on the properties of the newly manufactured metal-polymer composites containing spatially oriented chains of Galfenol anisotropic particles in the polyurethane matrix. The magnetic and mechanical properties of the metal-polymer composite have been subject to experimental study that has shown the non-monotonic increase of the composite magnetodeformational response with particles concentration rise in polymer matrix. The explanation of this phenomenon was given on the basis of structural investigation of metallic particles chains direction and their density in the sample by means of TEM, SEM and 3D X-ray computed tomography. The maximum value of functional magnetodeformational characteristics has been obtained for the composition with 15% particles volume fraction with preferable spatial orientation in longest particle chains.
