Abstract

Methods include determining a desired hysteretic curve that corresponds to a set of dynamic mechanical analysis parameters, where the desired hysteretic curve comprises elastic portions and plastic portions, and the elastic and plastic portions comprise specific desired shapes. A first tuned carbon is selected, the first tuned carbon facilitating achievement of a desired shape of a particular elastic portion of the hysteretic curve. One or more selected post-treatments is performed on the first tuned carbon to form a first post-treatment carbon, the selected post-treatment facilitating achievement of a desired shape of a particular plastic portion of the hysteretic curve. The methods also include combining the first post-treatment carbon with other materials that are used in components of the tire and curing the combination comprising the first post-treatment carbon and the other materials. Carbon and elastomer compounds are also disclosed.

Claims

1. A method for manufacturing a tire comprising:

determining a desired hysteretic curve that corresponds to a set of dynamic mechanical analysis parameters, wherein the desired hysteretic curve comprises elastic portions and plastic portions, and the elastic and plastic portions comprise specific desired shapes;

selecting a first tuned carbon, the first tuned carbon facilitating achievement of a desired shape of a particular elastic portion of the hysteretic curve;

performing one or more selected post-treatments on the first tuned carbon to form a first post-treatment carbon, the selected post-treatment facilitating achievement of a desired shape of a particular plastic portion of the hysteretic curve;

combining the first post-treatment carbon with other materials that are used in components of the tire; and

curing the combination comprising the first post-treatment carbon and the other materials.

2. A compound comprising:

an elastomer material; and

a carbon material comprising graphene flakes assembled into three-dimensional scaffolds, wherein the three-dimensional scaffolds are decorated with graphite particles.
