Removal of Solid Filler Particles from Composite with Polymer Matrix as a Factor of Abrasive Wear

It is shown that wearing of polymer disperse composites in a medium with a nonfixed abrasive is accompanied by removal of the filler particles with wear of the base, which occurs by means of shear and rotation owing to deterioration of the adhesion strength of the system “particle–matrix”; the adhesion strength is determined by the adhesion of the composite, size and spatial arrangement of particles, and the area of their contact with the matrix.
