Malezhyk P. Anisotropy of physical and mechanical properties of epoxy systems formed in a magnetic field

Thesis is dedicated to the influence of a constant magnetic field on the structure and properties of epoxy systems during curing. The influence of CMF on epoxy systems have been investigated by methods of thermomechanical analysis (TMA), the differential mechanical analysis (DMA), differential scanning calorimetry (DSC). The results of investigations of the optical, mechanical, and thermal relaxation properties solidified epoxy systems with the hardener of different chemical structure and isomerism, and nanocomposites based on them, formed in a constant magnetic field (CMF) have been represented. The results of epoxy resin kinetics investigation structuring under CMF showed an appearence of elastic characteristics anisotropy that indicating about the existence of crosslinking density depending on the spatial grid with respect to the orientation of the lines ofexternal CMF. The regularities in origin and manifestations of anisotropy of physical properties have been studied. The explaination of the effect of the magnetic field at various levels of structural organization of epoxy systems has been suggested.
