Incorporation of Graphene to Enhance the
Strength of Composites in Automotive
• Improved compression strength by 20%
• Increased heat deflection temperature by 15oC
Improved Noise Vibration ⬣ Improved Manufacturability ⬣ Easier CB Handling
Elastomers: Potential to decease rolling resistance
Structural Applications: Lightweighting and potential increases in lifecycle of final
product
Functional Foams, Headliners, and Textiles: Potential to replace toxic FR
Thermoelectric Materials: Potential cooling and heat recovery improvements
Can be used in sensors for safety and environmental protection and detection
Potential to use in nanofluids for thermal management
• Improved NVH (noise & vibration) by 17%
