Description
| - Investigation of the flow behaviour of melted composites of hard metal carbide powder in a polymer matrix showed that at high filler loading (50 vol.%) in a capillary rheometer operating at a constant piston speed pressure oscillations occurred. This flow instability has been attributed to the thin interparticle layers leading to a strong particle interaction. The measurement of electric conductivity of the solid composite materials in this range of particle concentration demonstrated that its dependence on temperature suggests a specific composite structure with a great number of conducting contacts. Unlike the composites with lower particle concentration, where the expansion of the non-conducting polymer matrix with increasing temperature caused interruption of conducting paths and a rapid drop in conductivity (switching effect), at high filler content most of conducting contacts remain unchanged and conductivity decreased with temperature only slightly.
