Provided is an elastomer reinforcement cord for which the problem of stress concentration at an interface between an elastomer and a metal cord has been resolved to improve durability. The elastomer reinforcement cord comprises metal filaments (1a and 1b) and a polymer material 3 having a melting point or softening point of 80 DEG C or more and 160 DEG C or less. Where a region outside the metal filaments within a region that has a core (11) and at least one sheath layer (12) and is surrounded by lines connecting the centers of the metal filaments constituting the outermost sheath layer in a cross section in the direction orthogonal to the axial direction after vulcanization is taken as a gap region, the gap region includes the polymer material, and the filling ratio, which is the proportion of the area of the polymer material, is more than 120% where the area of the gap region is 100%.
提供一种弹性体增强帘线,其解决了应力集中在弹性体和金属帘线之间的界面处的问题,从而改善了耐久性。弹性体增强帘线包括金属丝(1a和1b),以及熔点或软化点为80℃以上且160℃以下的高分子材料(3)。将具有芯(11)和至少一个鞘层(12)、并且在硫化后的与轴向正交的方向上的横截面中被连接构成最外层鞘层的金属丝的中心的线包围的区域内的金属丝以外的区域作为间隙区域,间隙区域包括高分子材料,并且在间隙区域的面积为100%的情况下,作为高分子材料的面积比例的填充率高于120%。
