Purpose: The aim of this paper was to investigate the effect of wood filler additions on the microstructure, fractographic features and cracking mechanism of low density polyethylene (LPDE). Design/methodology/approach: For the tests, waste polyethylene from industrial and common films and Lignocel CB 120 wood fibers have been used. Three types of compositions (composites) with 10, 20 and 30% of wood flour have been prepared for the tests. To evaluate the role of used filler conducted it’s quantitative analysis by linear method. Parameters like volume fraction of the filler, the number particles of wood flour per surface area and mean wood fiber diameter, were determinated. Findings: The results of microscopic observations of the etched sections and fractures obtained at room temperature and at liquid nitrogen temperature indicate good matching between the filler particles and the structure of basic polymer, due mainly to bonding of the individual lamellae in spherulites. The reinforced polymer reveals a cracking micromechanism which is called crazing. Research limitations/implications: The further research are required to solve the problem of the filler contrast. Practical implications: From practical point of view, this research can be used to project composites (wood flour – polyethylene). Originality/value: Originality of this work is the fact that stereological measurements shown usefulness this method to estimate filler’s influence of forming microstructure and properties of the investigated composite.

W niniejszej pracy przeprowadzono badania mikrostruktury recyklatu polietylenu oraz jego różnych kompozycji, z mączką drzewną (od 10 do 30%). Wpływ roli napełniacza w poszczególnych kompozycjach oceniano jakościowo i ilościowo. Mikrostrukturę badanych tworzyw określono na zgładach jak i przełomach próbek.
