Abstract
The wear of multiphase composite materials is modeled as accumulation of microdamage in each component. The probability of damage in the composite components is assessed by solving a statistical boundary-value problem of the micromechanics of structurally inhomogeneous media subject to coupled processes of deformation and microdamage. The accumulation of microdamage is described by random functions whose statistical characteristics for each component are determined experimentally. The approach is validated by comparing the calculated and experimental wear of 15 multiphase composite materials. It is established that the content of fiber reinforcement, thermally expanded graphite, and boron nitride influences the wear of composite materials.
