| Summary: | Title screen Biomechanical properties of composites based on UHMWPE and hybrid (polymerpolymeric)matrices “UHMWPE+PTFE” with disperse particle fillers were studiedin order to develop materials for artificial joint implants. A comparative analysisof the efficiency on loading hydroxyapatite (HA) powder as biocompatiblefiller was performed. It was shown that wear rate of nanocomposites with thehybrid matrix is lower as compared with UHMWPE composites in conditions ofdry friction and boundary lubrication. To optimize the composition of implantmaterials it is proposed to use the theory of dispersion hardening through theMori-Tanaka model and Ilyushin function of plasticity as well as two-level methodof computer-aided design. Comparison of calculation estimates by the developedtechnique with experimental data have shown that their relative error does notexceed 15 %. Lowered values of the tensile strength of the nanoparticles filledcomposites is suggested to be due to lacking the interfacial layer consideration.Mechanical activation of powder components further enhances the durabilityof nano and micro composites almost doubling them without any substantialreduction in the strength properties. It is shown that wear resistance of nanoandmicro composites with hybrid matrix under boundary lubrication is close tothat at dry sliding friction. |
