Fracture behaviour of epoxy nanocomposites modified with triblock copolymers and carbon nanotubes

The effect of the addition of a combination of rigid nanofillers and soft rubber nanoparticles on the fracture toughness of epoxy resins was studied. Carbon nanotubes (CNTs), as rigid nanofillers, and polystyrene-polybutadiene-poly(methyl metacrylate) (SBM) triblock copolymers, as rubber nanoparticles that self-assemble in the epoxy matrix, were used. Fracture tests according to ESIS TC4 protocol were performed on neat epoxy, epoxy reinforced...
