Carbon nanotube technology toughens carbon-fiber composite materials

Under mechanical stress, carbon-reinforced epoxy-resin composite materials can experience cracking and de-lamination at the junctures between layers of material, where the composites are resin-rich. Placing vertically aligned carbon nanotubes (VACNTs) into the inter-laminar regions can toughen the composite and prevent…
