description: The possibility of using nanosized copper particles as a filler for polyether ether ether ketone (PEEK) has been investigated On the basis of a physical model of wear, the possibility of developing a tribotechnically effective composite with a filler of low wear resistance has been investigated; calculated concentration dependences of the relative intensity of linear wear of the composite in relation to the matrix for four sizes of dispersed filler from the nano- and micro-size range have been constructed. As a result, the ranges of effective filler concentrations when nano-copper is introduced into PEEK were determined. A molecular dynamics method was applied to investigate the reasons for the increase in the wear resistance of the nanocomposite upon introduction of dispersed copper particles. It was obtained that the energy of intermolecular bonds significantly increases in the presence of filler. As a result of modeling of sliding friction of molecular models, differences in the density of molecules in the area of contact with the counterbody before and after shear, as well as differences in the values of the energies of intermolecular interaction between the contacting surfaces depending on the shear time were revealed. Comparison of the data obtained as a result of modeling the molecular structures of the polymer matrix and composite with the constructed concentration dependences of the relative intensity of linear wear of the composite in relation to the matrix allows us to identify an additional reason for the increase in wear resistance of the composite and, in the future, to assess the change in wear resistance of the composite and to estimate the change in wear resistance by the value of the change in the energy of intermolecular bonds.
