Original abstract

In this paper polymeric particulate composites are studied (especially polypropylene (PP) matrix stuffed by rigid mineral fillers). Presently, polymeric particulate composites are frequently used in many engineering applications. The composite was modeled as a three-phase continuum; matrix, interphase and particle. The properties of the particles (size, shape) have a significant effect on the global behaviour of the composite. On the basis of fracture mechanics methodology the interaction of micro-crack propagation in the matrix filled by rigid particles covered by the interphase was analyzed. The effect of the composite structure on their mechanical properties is studied here from the theoretical point of view.

Czech abstract

V tomto příspěvku jsou studovány polymerní částicové kompozitní materiály. Částicový kompozit byl modelován jako třífázové kontinuum – matrice, mezivrstva a částice. Tvar a velikost částic má významný vliv na chování kompozitu jako celku. Na základě lineárně-elastické lomové mechaniky je analyzováno chování trhliny šířící se matricí, ve které jsou různě velké a orientované částice.
