Abstract (en)

[origin: EP0790349A1] A steel cord (10) adapted for the reinforcement of an elastomer comprises steel filaments (12,14) of a pearlitic structure. The steel cord has a plastic and elastic elongation at break of x % and a plastic and elastic elongation capability in the vulcanized elastomer of y %, the values x and y fulfilling following equation : <MATH> which means that the total elongation at break does not reduce considerably after embedding the steel cord into an elastomer. The steel core (10) has a high elongation capability which is largely independent of the structure of the steel cord. <IMAGE> <IMAGE>
