STABILITY BEAM SUPPORT FOR ELASTOMERIC PRODUCTS, IN PARTICULAR FOR A CARCASS BEARING OF A PNEUMATIC TYRE FOR A VEHICLE, COMPRISING A HYBRID CORD

摘要

Reinforcement layer (9) for elastomeric products, in particular for a carcass ply of pneumatic vehicle tires, the strength carriers are arranged within the layer (9) substantially parallel to each other and embedded in elastomeric material, wherein the reinforcement layer (9) at least one hybrid cord (20) reinforcement carrier having which is composed of at least one yarn (21) is constructed of aramid yarn and at least one (22) of rayon, all yarns (21) (22) of the hybrid cord (20) are final-twisted together. It is an object of the invention to provide a strength element ply for elastomeric products, in particular a carcass ply of pneumatic vehicle tires having an increased durability under impact stress. This is achieved by passing the yarn (21) of aramid yarn is a yarn (21) from meta-aramid and by the yarn (21) of meta-aramid has an elongation at break of at least 20%. Furthermore, the invention relates to a pneumatic vehicle tire comprising such a reinforcement layer.
