Preferably, the short fibre has an average diameter of 0.01 to 0.20 mm and an average length of 1.0 to 10.0 mm, and the proportion of the short fibre is 3 to 15 parts by weight with respect to 100 parts by weight of the rubber. The hybrid material has a 100% modulus of at least 10.0 MPa, a tensile strength of at least 10.0 MPa, a breaking elongation EB of at least 200 %, a Mooney viscosity of from 30 to 50 ML1+4, and a scorch time (t10) of at least 20 minutes. Optionally, a reinforcing cord layer (8) embedded in the bead apex (5) or a bead core (20) disposed immediately radially inside the bead apex is used.

    摘要： The present invention aims to provide a surface modification method for a rubber vulcanizate or a thermoplastic elastomer, which can impart excellent sliding properties and excellent durability against repeated sliding motion and can allow the surface to maintain the sealing properties, without using expensive self-lubricating plastics. The present invention relates to a surface modification method for modifying a rubber vulcanizate or a thermoplastic elastomer as an object to be modified, the method including: step 1 of forming polymerization initiation points on the object to be modified; step 2 of radically polymerizing a monomer, starting from the polymerization initiation points, by irradiation with LED light at 300 nm to 400 nm to grow polymer chains on a surface of the object to be modified; and step 3 of esterifying, transesterifying or amidating side chains of the polymer chains.
