Abstract
A composite material includes an elastomer matrix forming a basic component of the material. There is included a cross-linking system of the elastomer matrix and at least one fiber reinforcement including fibers with a maximum length of about 30 mm. The fibers are disposed throughout the elastomer matrix and are generally oriented to extend in a first direction of reinforcement. There is at least one thermosetting resin in the elastomer matrix. The elastomer matrix which includes the cross-linking system, the fiber reinforcement and the thermosetting resin has a first equivalent tensile modulus which is calculated for a hypothetical elongation of 100% in the first direction and a second equivalent tensile modulus which is calculated for an actual or hypothetical elongation of 100% in a second direction which is perpendicular to the first direction. A second equivalent tensile modulus is at least 6 MPa. Anisotropy ratio of the first equivalent tensile modulus and the second equivalent tensile modulus is at least 6.
