<abstract xmlns="http://www.w3.org/1999/xhtml"><p>This paper reports the results of research on the mechanical properties of hDPe-matrix composite filled with three types of neuburg siliceous earth (nse). The hDPe/nse composites are prepared by twin-screw direct extrusion, with the filler content ranging between 0wt% and 60wt%. Thereby, the prepared molded pieces are subjected to tests in order to determine Young’s modulus and tensile strength, impact strength and hardness. The results are thoroughly examined based on the morphological and geometrical features of the applied fillers, such as particle size (2–10 μm) and specific surface (7–9 m2/g). The effect of the chemical properties of the filler surface on its interaction with the matrix and strength is determined. The effects of the chemical activation of the filler surface by vinyl-functional silanes on their strength properties is described, and the variations in interactions on the matrix-filler interface are explained.</p></abstract>
