Abstract
Springy fibers, when used as a fiber reinforcement in an elastomer, have been found to demonstrate reduced crack propagation in the elastomer. Springy fiber reinforced elastomers can be used in tires in various components.
Claims7
A pneumatic tire including a component comprising an elastomeric matrix material having dispersed therein about 1 to about 10 phr artificially crimped synthetic organic springy fibers having a length of about 100 to 12,000 um, a diameter of about 1.2 to 1,250 um and an aspect ratio of 25 to 1000, said springy fibers being selected from the group consisting of nylon, polyethlene, polypropylene, polyester and mixtures thereof.
