Conclusions

The optimum shape of hard inclusions in a composite material, irrespective of the magnitude of load and mode of its application to the surface, is a spheroid or ellipsoid of revolution. The characteristic linear size of a hard inclusion should be greater than the calculated diameter of a single spot of contact. If a composite material is to exhibit high fatigue strength, it is necessary to ensure that the spacing between its hard and wear-resistant inclusions is not less than (1.5–2)a (a is the characteristic linear size of the inclusions).
