Effect of mechanical properties with addition of graphene nano-platelets in Cu/ GNPs composite- green part

Graphene is one of the best reinforcement materials but have a strong tendency to agglomerate and will affect the final properties of the composite. Effect of mechanical properties with addition of Graphene Nano-platelets (GNPs) in copper through powder injection molding (PIM) process was invest...
