<p>A steel cord reinforcement for elastomers and elastomeric articles comprising a steel cord crimped in a zig-zag fashion used in the warp direction of the reinforcing fabric; the crimps of adjacent warped cords lie in phase, and the wave length p of the crimp and the amplitude c of the crimp are related such that 0.02 p</=c</=0.07 p; to achieve optimal properties of cord elongation and cord deformation, the relationship S=k p2 wherein 0.7</=k</=3, and the stiffness S=104N [ SIGMA (Di4xni)] wherein Di represents the diameter of wire filament "i" in the cord, ni is the number of wires "i" per warp cord, and N is the number of warp cords per mm width of the fabric.</p> |
