Résumé
This paper presents a study of the electrical conductivity of wood-polymer composites, determined by measurements done in DC and AC current. It is also noticed that the values of sigma(dc), sigma and sigma '' are strongly influenced by the nature of matrix and filler content of the composite. Finally, it is sown that samples of PE and PP matrices can be used for applications in power frequency electric fields (0 ... 100 Hz) and at temperatures between 30 and 90 degrees C.
