Abstract
The invention relates to a carbon nanotube-modified epoxy resin adhesive for sticky carbon fiber reinforcement. The adhesive comprises an epoxy resin matrix and carbon nanotubes, wherein the mass of the carbon nanotubes is 0.1%-15% of the total mass of the epoxy resin matrix; amine groups capable of reacting with the epoxy resin can be grafted on the carbon nanotubes by carrying out surface treatment on the carbon nanotubes to obtain a good modification effect; when ingredient blending is performed during reinforcement construction, 20-50 parts of an epoxy curing agent is added into 100 parts of carbon nanotube-modified epoxy resin. The cured epoxy resin adhesive modified by the method disclosed by the invention has the advantages of relatively high tensile strength, compressive strength, bending strength and shearing tensile strength, relatively high mechanical properties and good carbon fiber wetting properties, is more suitable for the sticky carbon fiber reinforcement process and can play a better reinforcement effect.
