Graphene nanomaterial is being used by Ford for noise reduction.

 

“Ford Motor Co. (Dearborn, MI, US) has announced that it will use graphene nanomaterial to enhance foam materials that reduce noise inside its vehicles and increase performance under the hood.
 
Debbie Mielewski, Ford senior technical leader for sustainability and emerging materials, says, “The breakthrough here is not in the material [graphene], but in how we are using it.
 
We are able to use a very small amount, less than a half percent, to help us achieve significant enhancements in durability, sound resistance and weight reduction — applications that others have not focused on.”
 
Graphene nanoplatelets, first isolated in 2004, consist of multiple layers or stacks of graphene sheets, which are bonded carbon atoms in sheet form one atom thick.
 
These ultrathin carbon particles have demonstrated unique performance capabilities for energy storage, thermal conductivity, electrical conductivity, barrier properties and the ability to significantly improve mechanical properties when incorporated into plastics or other matrices, according to XG Sciences Inc. (Lansing, MI, US), the manufacturer of the graphene material trademarked under the name xGnP.

In tests done by Ford and its suppliers, foam constituents with added graphene have shown about a 17% reduction in noise, a 20% improvement in mechanical properties and a 30% improvement in heat endurance properties, compared with foam used without graphene.”
