Enhanced interlaminar fracture toughness of carbon fiber reinforced composites through graphene oxide additions

Delamination is considered a major concern in carbon fiber reinforced composite materials. Modification of laminate surface has been done with nanofillers like clay, carbon nanotubes, and expanded graphite to toughen the interlaminar area and prevent delamination. In this study, an environmentally friendly thermoplastic carrier, polyvinyl pyrrolidone (PVP) and nanoparticles of Graphene oxide (GO) mixtures in pre-determined ratios were …
