Abstract
A carbon composite contains expanded graphite; and at least one of a filler or a reinforcement; wherein the expanded graphite comprises a plurality of randomly oriented basal planes. Methods of making the carbon composite and articles comprising the carbon composite are also disclosed.
Claims23
A carbon composite comprising:
- expanded graphite;
- and
- at least one of a filler or a reinforcement;
- wherein the expanded graphite comprises a plurality of randomly oriented basal planes.
1 more element
A method for making a carbon composite, the method
- comprising
- combining expanded graphite and at least one of a filler or a reinforcement to form a combination;
- and
- compressing the combination under an isostatic pressure thereby making the carbon composite;
- wherein the basal planes of the expanded graphite in the carbon composite are randomly oriented.
2 more elements
A method for making a carbon composite, the
- method comprising
- compressing a composition comprising expanded graphite to form a pre-form comprising an expanded graphite matrix and a plurality of connecting open pores disposed in the matrix;
- and
- combining the pre-form with a filler thereby making the carbon composite;
- wherein the expanded graphite matrix in the carbon composite comprises a plurality of randomly oriented basal planes.
2 more elements
A method of forming a carbon composite, the method comprises:
- firstly compressing expanded graphite to form compressed expanded graphite;
- milling the compressed expanded graphite to form expanded graphite particles;
- combining the expanded graphite particles with at least a filler or a reinforcement to form a combination;
- and
- secondly compressing the combination thereby making the carbon composite;
- wherein the expanded graphite in the carbon composite comprises a plurality of randomly orientated basal planes.
