Abstract

It is shown analytically that one of the reasons for the improvement of the tribotechnical properties of polymer composites obtained using the technology of dissolution of filler particles in the polymer melt is the reduction of the matrix loading due to the existing possibility of aggregation of a significant part of the dispersed particles into aggregates that are oriented perpendicularly to the contact surface. The dependences are obtained that reflect the connection between the magnitude of the relative intensity of composite linear wear and the value of the volume concentration for nano- and microparticles of the filler. The cases of filling with particles of materials with higher and lower shear resistances relative to the matrix one are considered.
