Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, has garnered significant attention for its exceptional mechanical, electrical, and thermal properties. When incorporated into fiber-reinforced polymer (FRP) composites, graphene can substantially enhance their performance, making them suitable for a wide range of applications.
Enhancements in Graphene-Enhanced Composites
Integrating graphene into FRP composites offers several notable improvements:
Feature | Benefit |
