▎ 摘  要

NOVELTY - Composition comprises a thermoset resin, multiple graphene flakes dispersed in the thermoset resin having a lateral dimension and a thickness, and a reinforcement material dispersed in the thermoset resin, where 90% multiple graphene flakes are oriented such that the lateral dimension is within 10 degrees of a parallel alignment with a horizontal plane. USE - Composition for producing sheet molding compound. ADVANTAGE - The composition improved by properly aligning the graphene flakes, and mechanical improvements brought on via reinforcement by graphene flakes are more significant when the graphene flakes are oriented parallel or substantially parallel to one another. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A method for producing a sheet molding compound, which involves: mixing a thermoset resin with multiple graphene flakes and a reinforcement material, the graphene flakes having a lateral dimension and a thickness, placing the slab of composite material onto a platform; and pressing the slab of composite material to form the slab of composite material into a second shape, where second shape different from the first shape, where the pressing forces the composite material to move through a pathway that is sufficiently narrow such that 90% of the graphene flakes become aligned with the lateral dimension within 10 degrees of a horizontal plane. An article, which comprises a thermoset resin, multiple graphene flakes dispersed in the thermoset resin having a lateral dimension and a thickness, and a reinforcement material dispersed in the thermoset resin configured to enhance mechanical stability of the sheet of material, where 90% multiple graphene flakes are oriented such that the lateral dimension is within10 degrees of a parallel alignment with a bottom surface of the article.
