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.

First claim

What is claimed is:

1. A method for manufacturing a tire, the method comprising:
determining a hysteretic curve indicative of one or more mechanical properties of the tire, the one or more mechanical properties including at least a deformation of the tire;
selecting a carbon structure based at least in part on the hysteretic curve;
generating a post-treatment carbon based on the carbon structure;
combining the post-treatment carbon and one or more materials;
curing the combination of the post-treatment carbon and the one or more materials; and
forming the tire based on the cured combination.

2. The method of claim 1 , wherein the tire comprises:
a plurality of one or more elastic portions; and
a plurality of one or more plastic portions, wherein any one or more of the plurality of elastic portions and the plurality of plastic portions comprises one or more shapes.

3. The method of claim 2 , wherein the carbon structure is configured to define the one or more shapes.

4. The method of claim 1 , further comprising determining a surface functionality of the carbon structure.

5. The method of claim 1 , further comprising performing a dynamic mechanical analysis on the carbon structure.

6. The method of claim 1 , wherein the one or more materials includes any one or more of elastomers, additives, or accelerants.

7. The method of claim 1 , further comprising determining whether or not the carbon structure has performance specifications that meet the set of mechanical properties of the tire.

8. The method of claim 7 , further comprising tuning one or more parameters associated with manufacturing the tire based on the determination.
