Influence of fracture toughness on the impact properties of carbon nanotubes/aramid fibre reinforced composite

This research was carried out to investigate the relation of the fracture toughness of epoxy/CNT/twaron on the impact properties by dividing into two phases and use design of experiment (DoE) approach. In Phase 1, the effect of parameters such as epoxy viscosity, CNT content, stirring time, stirring...
