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.sup.2 -352.6D.sup.3)CE.
Claims2
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.
