P. Velev et alii, Frattura ed Integrità Strutturale, 37 (2016) 272-279; DOI: 10.3221/IGF-ESIS.37.36 279 C ONCLUSIONS he nanocomposites on the basis of diluted with water unsaturated polyester resin containing magnetic nanoparticles with concentration ranging from 0.1% to 0.5% were successful prepared. It was established that the increased concentration of the magnetic nanoparticles leads to decreased mechanical properties of the composites due to the formation of micropore structure. As expected the specific volume and surface resistance of the composites is changed with increasing the amount of magnetic nanoparticles in the composites.
