Abstract

Materials make it possible to generate mechanical coupling in elastomeric compositions, of use especially for the manufacture of tyre treads. In particular, a tread comprises a composite material based on an elastomeric matrix, a crosslinking system, a reinforcing filler and oriented short fibres.
