Résumé

An increase in the wettability of dispersed particles with a polymer is one of the main tasks when creating polymer composite materials reinforced with a dispersed filler. Wettability can be increased due to the polymer shells provided on the surfaces of the particles. By varying the polymer shell thickness of the filler particles, the mechanical properties of the polymer composite materials can be controlled. In a polymer matrix with partial crystallinity, the stress-strain states can be induced by the orthotropy of macromolecules near the filler particles. The main reasons for the stress-strain states are the differences in the mechanical properties of the polymer and filler particles and the technological parameters. In this paper, mathematical modeling results for the occurrence of internal residual stresses are obtained using a three-phase structural model of polymer composite materials. It is shown that these technological stress-strain states are independent of the orientation of polymer molecules to the filler particles in crystallites, and they can decrease the mechanical properties of the entire composition. Thus, the effect of submicron filler particles with polymer shells on the mechanical properties of the polymer composition may vary depending on the amorphous or crystalline structure of the polymer matrix.
