In a first for the automotive industry, Ford, along with Tier I Eagle and graphene supplier XG Sciences, have discovered a way to use extremely small amounts of graphene Elene is used to improve key properties of automotive components under the hood, namely lighter weight, better thermal conductivity and reduced noise. The material has been dubbed xGnP graphene-reinforced polyurethane (PU) foam.
Graphene is 200 times stronger than steel and is one of the most conductive materials in the world. It’s a huge sound barrier that’s very thin and flexible. Graphene is not economically feasible for every application, but Ford, in partnership with Eagle Industries and XG Sciences, has found a way to use small amounts of graphene in fuel rail covers, pump covers and front engine covers to maximize Maximize its effectiveness.
<span style="font-size: 16px" It's not about the material, it's about how we use it. We were able to use very small amounts, less than fifty percent, to help us get significant improvements in durability, sound resistance and weight reduction – something that others There are no following apps."
In 2014, Ford began working with suppliers to study this material and how it could be used in automotive parts ( It is used in tests such as fuel rail covers, pump covers and front engine covers). Typically, trying to reduce cabin noise means adding more material and weight, but graphene does the opposite. John Bull, president of Eagle Industries, said: “A small amount of graphene goes a long way, and in this case, it plays a big role in sound absorption properties.”
Graphene mixed with PU foam components, tests conducted by Ford and suppliers have shown that it is as effective as without graphene Compared with foam, the noise is reduced by 17%, the mechanical properties are improved by 20%, and the heat resistance is improved by 30%.
