An investigation on mode II fracture toughness enhancement of epoxy adhesive using graphene nanoplatelets

Epoxy adhesive has a great potential use in different areas which may encounter impact loadings, the fracture behavior of epoxy adhesive needs to be improved to meet the safety requirement. This paper experimentally studies the dynamic mode II fracture toughness of an epoxy adhesive reinforced by different content of graphene nanoplatelets (GNPs) through compliance-based beam method (CBBM). Typical R-curves of the neat epoxy adhesive and...
