Description

technical field [0001] The invention relates to the technical field of modified engineering plastics for automobile lightweight production, in particular to a carbon nanotube modified carbon fiber composite material used for automobile hubs and a preparation method thereof. Background technique [0002] Carbon fiber reinforced resin matrix composites (CFRP) have excellent mechanical properties and are widely used in structural parts such as automobiles, aircraft, and electronic appliances. In recent years, due to the development needs of lightweight automobiles, the requirements of CFRP mechanical properties and functionalization have been continuously improved, and the research on multi-scale hybrid filling has been developed, especially in carbon fiber / carbon nanotube hybrid filled polymer composites. . However, due to its nanoscale size, large specific surface area and aspect ratio, carbon nanotubes (CNTs) have a large surface energy and are prone to agglomeration, and t...
