Abstract

Cord (36) reinforced composites 26 for tires (10) or the like having cords 36 in a diameter range of 0.30 mm to 1.6 mm with a cord break strength (CBL) of N(720.4D 2 -352.6D 3 )CE.

Claims

exact text as granted — not AI-modified

We claim: 
     
       1. A reinforced layer of elastomer for reinforcement of elastomeric articles having at least one layer of cord spaced in a direction lateral to the direction of reinforcement, each cord have a diameter in the range of 0.30 mm to 1.6 mm and formed in a single step where all its filaments have the same lay direction, each cord made of steel having a cord break strength (CBL) defined by the expression:   CBL=N(720.4D.sup.2 -352.6D.sup.3)CE     where CE is the cord efficienty, D is the filament diameter of 0.255 MM and N is the number of filaments in each cord.   
     
     
       2. The reinforced layer of elastomer in claim 1 wherein the cord construction is 2×0.255.
