Reinforced product with fixed cord geometry and with dual modulus behavior and adaptive stiffness

The invention relates to a reinforced product (R) comprising a polymer matrix (Ma) and at least one cord (50), said cord (50) comprising a single layer of N metal reinforcing elements, which can be:-a metal wire (F) having a diameter Df wherein the metal reinforcing element (54) has a diameter Dh and a diameter D, the diameter Dh is the diameter of a theoretical circle passing through the center of the thread (F) of the layer in a plane perpendicular to the main axis of the cord, the diameter D being the outer diameter of the cord (50); -or strands (T) helically wound around the main axis (A), each strand (T) comprising a strand consisting of Mgt; a single layer (56) of one metal wire (FT) wound helically about the axis (B) and having a diameter Df, in which the metal reinforcing element (54) has a diameter Dh, which is the diameter of a theoretical circle passing through the center of the wire (FT) of the layer (56) in a plane perpendicular to the main axis of the strand (T), and a diameter D, which is the o
