Abstract
The present invention relates to a novel tire cord reinforcement made of ultra high modulus aramid fibers which has bi-elastic tensile properties. The cord includes at least two plies, and there is a spacing between the cord plies. Such a novel bi-elastic tire cord improves high speed durability and eliminates flatspotting when used as carcass reinforcement in pneumatic radial and bias tires.
Claims8
A dipped and heat-set aramid cord, comprising a plurality of plies having a spacing between the plurality of cord plies, wherein a TASE at 1.0% elongation of the aramid cord is less than 2.0 cN/dtex;
- wherein the spacing between the plurality of cord plies is longer than 10% and shorter than 50% of a cord diameter (D) of the cord plies.
