EFFECT OF THE CONTENT TUNGSTEN ON THE MECHANICAL PROPERTIES AND THERMAL STABILITY OF COMPOSITE MATERIAL BASED ON POLYSTYRENE.

Abstract

The influence of the composition of the composite tungsten-polystyrene on its micro hardness and heat resistance was investigared. It is shown that the introduction of micropowder tungsten into the volume of polystyrene matrix results in the linear increase in the microhardness of the composite in the range of 0-3 vol. %. Further increasing the concentration of tungsten up to 30 vol. %, also results in the linear increase in the microhardness, but with a smaller slope. Thermal stability of samples monotonically depends on the concentration of tungsten and has a maximum at 10 vol. %.
