STEEL CORD FOR REINFORCING RUBBER ARTICLE AND TIRE USING SAME |
摘要 |
Provided is a technique for attaining tire weight reduction while inhibiting occurrence of a product defect caused by deformation by improving the structure of a steel cord used for a carcass ply to improve the resistivity against deformation of a green tire when stored in an unvulcanized state.;Also provided is a steel cord for reinforcing rubber articles with a multi-twisted structure in which a plurality of strands 11, 12 formed by twisting a plurality of wires 1, 2, 3 together in a layered-twisted structure are twisted together in a 2-layer-twisted structure. The cord mass is from 35 g/m to 65 g/m, and the ratio of flexural rigidity G (N·mm2) to cord cross section A (mm2), G/A (N) is from 400 N to 650 N. |

1. A steel cord for reinforcing rubber articles with a multi-twisted structure in which a plurality of strands formed by twisting a plurality of wires together in a layered-twisted structure are twisted together in a 2-layer-twisted structure, wherein a cord mass is from 35 g/m to 65 g/m, and the ratio of flexural rigidity G (N·mm2) to cord cross section A (mm2), G/A (N) is from 400 N to 650 N. |
