Micro-hardness of glass fiber-filled PBT influenced by beta low radiation doses

Abstract

The presented article deals with the research of micromechanical properties in the surface layer of modified PBT filled by 35% of glass fibers. The glass fiber-filled PBT modification was carried out with the aid of β - radiation at different radiation intensities and the resulting properties were measured with the aid of micro-indentation test by the DSI (Depth Sensing Indentation) method. The purpose of the article is to consider to what extent the irradiation process influences the resulting micro-mechanical properties measured by the DSI method.
