The paper discusses the issues regarding the cohesion of dispersed reinforcement with the matrix of the composite. There is developed an original method allowing determining the characteristic of the cohesion, which takes into account the position and orientation of the fiber, the nature and context of its work in the matrix. The author determines the strength amorphous metallic fibers when tested in the concrete of R am.f = 996 MPa and the bonding strength of steel fibers τst.f = 3,08 MPa.
