Abstract

The invention relates to a composite cord (10) for reinforcement of elastomers comprising a core (12) of a high polymer material, a first layer of steel filaments (14) twisted around said core and a second layer of steel filaments (16) twisted around said first layer. The polymer material is present in a sufficient volume to create gaps between adjacent filaments of the first layer and possibly also between the filaments of the second layer. The composite cord is characterized by a decreased fretting of the steel filaments.
