Carbon fiber composites comprising carbon fiber coated carbon nanotube/graphene oxide hybrid and the manufacturing method thereof

摘要

The present invention includes a polymer matrix and carbon fiber provided into the polymer matrix. The carbon fiber provides a carbon fiber composite of which a surface is coated with a carbon nanotube/graphene oxide hybrid. According to the present invention, the carbon fiber composite includes: a carbon fiber coated with a graphene oxide hybrid without structural changes or deterioration of the physical properties of carbon nanotube, and has superior electrical conductivity of the carbon nanotube. Moreover, the carbon fiber composite can prevent cracks thereof since the tubular structure of the carbon nanotube coated on the carbon fiber has a Z-axis reinforcing effect, unlike when only the graphene oxide is coated on the carbon fiber.
