OF FILLED ELASTOMER STRENGTHENING

Relations invariantly relating the matrix deformation 
to the composite deformation have been derived. A model that permits 
obtaining a Mullins effect and explains the multiple increase in the 
strength characteristics of the composite compared to the matrix is 
proposed. At the basis of the model is the presence at the matrix-filler 
boundary of a hard rubber layer. This layer is formed due to the interaction 
between the active surface of the filler and the rubber macromolecules. 
The quantitative form of the tension distribution function density 
of active chains of the mesh explaining the strengthening phenomenon 
has been substantiated.
