Atomistic simulation of interfacial properties and damage mechanism in graphene nanoplatelet/epoxy composites
Computational Materials Science(2020)
摘要
•Effects of epoxy crosslinking density and number of graphene layers are studied on the traction-separation phenomena.•Double-layered graphene showed the highest interfacial strength.•The amount of movable epoxy chains has a direct effect on the softening response of the traction-separation curves.•At least two damage mechanisms are responsible for the interfacial failure.•The failure modes are a function of epoxy crosslinking density.
