Graphene / graphite-filled carbon fiber-reinforced composite designed especially for battery protection boxes in electric cars

The aim is to develop a new composite material intended primarily as a construction material for the creation of a lightweight multifunctional box for electric batteries for vehicles with electric drive. The composite material will provide: low weight, high specific mechanical properties including impact toughness and vibration resistance, effective control of thermal conditions in the box, longer life, fire safety, static charge limitation, corrosion resistance, electromagnetic compatibility and high resistance to water and water vapor penetration. The composite material will consist of an epoxy matrix reinforced with carbon multifilaments with a suitably activated surface filled with conductive carbon particles based on graphene and expanded graphite of optimized size and concentration.
