Abstract
The goal of this work was to study the structure and electrical properties of functional polymeric graded materials with epoxy resin matrix and copper powder as a filler. Gradation of the filler content and in this way gradation of electrical properties was obtained using centrifugal casting technology. Filler particles distribution in the matrix was controlled by changing casting parameters. Rotational velocity influenced particles distribution and electrical resistivity distribution the most significantly. Performed experiments showed that it is possible to control the structure of graded composites and in this way the gradation of electrical properties. Elaborated polymeric graded materials may be applied in many industrial fields where products with low surface electrical resistivity on one surface and high electrical resistivity in the rest of the volume are needed.
