DEFORMATION BEHAVIOUR ANALYSIS OF POLYSTYRENE KRASTEN171 WITH MONTMORILLONITE NANOFILLERS

Abstract

The paper is focused on the experimental investigation of the montmorillonite nanofillers effect on deformation properties of polystyrene KRASTEN 171. The combination of a low amount of clay with dispersed polymeric phase may cause synergistic effects leading to very fair balance of mechanical behaviour in some cases. The paper analyses the effect of nanocomposites and type of the material on the individual measured parameters, relations between them, strength and deformation behaviour. Deformations were evaluated by non-contact videoextensometry method. The results show that doping of the base material polystyrene with nanofillers particles has an effect on the plastic deformation increments.
