Based on the solution of the dynamic contact problem of vibration of a rigid punch
on a heterogeneous half-space, taking into account friction in the contact area, the tribological
properties of an oil-filled composite material with a microstructure are modeled. The
microstructure of the base is taken into account in the framework of the Biot-Frenkel model.
The boundary-value problem is reduced to the integral equation, its approximate solution is
constructed, which describes contact stresses, tangential displacements. The dependencies of
the friction forces on the microstructure of the composite, the viscosity of the fluid filling the
pores, and the degree of phase interaction are investigated.
