  • Reinforcement for rubber composites
    Publication number: 20030034107
    Abstract: A method for constructing an elastomeric composite ply comprises using parallel S and Z twisted cords to reinforce an elastomeric matrix. The S and Z cords are made inexpensively by using a yarn twist that is less than the cord twist. Composite plies made by the method can be used in elastomeric articles such as tires.

  • Pneumatic tire with specified aramid belt
    Patent number: 6267165
    Abstract: The belts of the reinforcing structure of a pneumatic tire are reinforced with high strength, light weight aramid cords having a linear density of 420 to 1100 dTex, the cords having a twist of 315 to 551 TPM (8 to 14 TPI). In alternative embodiments, overlay material may be incorporated into the belt reinforcing structure. An illustrated embodiment of the tire has a belt reinforcing structure comprising a folded belt folded around a cut belt.
