Provided is an elastomer reinforcement cord that: takes advantage of the characteristics of a composite cord that uses steel filaments and a resin filament; and has an actual post-vulcanization cord diameter that is substantially the same as the geometrically calculated value for the diameter of a cord that is only steel filaments without any resin as calculated from the wire diameter of the steelfilaments used. An elastomer reinforcement cord 10 that comprises metal filaments 2, 3 and a resin filament 1 that have been intertwined and has a core and at least one sheath layer, wherein the space between the metal filaments is filled with a resin. The cord diameter is 98%-100.5% of the geometrically calculated value for the diameter of a cord that comprises only metal filaments, and the total length of the spaces between the metal filaments in an outermost sheath layer pre-vulcanization is no more than 85% of the geometrically calculated value. In a cross-section that is orthogonal to the axial direction of the cord, of the area determined by the metal filaments that form the outermost sheath layer, the ratio of the area occupied by a polymer material to the area not occupied by metal filaments is 52%-120%.
提供了一种弹性体增强帘线,其利用了使用钢长丝和树脂长丝的复合帘线的特性;并且具有实际的硫化后帘线直径,其与仅有钢长丝而没有任何树脂的帘线的直径的几何学计算值基本上相同,所述几何学计算值是由所使用的钢长丝的线径计算出的。弹性体增强帘线10包括金属长丝2、3和树脂长丝1,它们捻合在一起并且具有芯和至少一个鞘层,其中,金属长丝之间的空间填充有树脂。帘线直径是仅包括金属长丝的帘线直径的几何学计算值的98%~100.5%,并且最外层鞘层中金属长丝之间的空间的总长度在预硫化前不超过几何学计算值的85%。在由形成最外鞘层的金属长丝所确定的面积的、与帘线的轴向正交的横截面中,被聚合物材料所占的面积与未被金属长丝所占的面积之比为52%~120%。
