Abstract

The invention discloses a method for loading a carbon fiber surface with carbon nanotubes. The method comprises treating carbon fiber filament bundles from a carbon fiber preparation phase washing workshop section through a carbon nanotube solution, carrying out sizing, carrying out treatment through a carbon nanotube dust raising chamber, carrying out drying and introducing the carbon nanotubes to the carbon fiber surfaces so that the carbon fibers with nanostructured surfaces are obtained. The method has simple processes, utilizes simple equipment and can be easily promoted and used in actual production. A resin-based composite material prepared from the carbon fibers obtained by the method has high interface performances.

Description

technical field

[0001] The invention relates to a method for modifying the surface of carbon fibers, in particular to a method for loading carbon nanotubes on the surface of carbon fibers. Background technique

[0002] As a high-performance fiber, carbon fiber has become the most important reinforcing material for resin-based composites in recent years because of its high specific strength, high specific modulus, small thermal expansion coefficient, low friction coefficient, and good low temperature resistance. The properties of composite materials are not only related to the properties of the reinforcement and the matrix, but also have a great relationship with the interface bonding strength of the reinforcement and the matrix.

[0003] Good interfacial bonding can effectively transfer loads and improve the mechanical properties of composite materials. If the interfacial shear strength of the material is low, when the material is destroyed, cracks mainly develop in the int...
