Abstract

The invention discloses a treatment method for a contact end of a surface of an oriented carbon nano tube-modified carbon fiber on the basis of gas-phase carbon nano tube dispersion mist. The method includes the steps of: 1) uniformly mixing carbon nano tubes, a sizing agent and a diluting agent to form a semi-fluid; 2) dispersing the mixture to form gas-phase carbon nano tube mist with pulsed arc; 3) moving a carbon fiber close to a discharge point of the arc; 4) forming relative constant-speed movement between the discharge point of the pulsed arc and the carbon fiber; 5) baking the carbon fiber in a baking oven; and 6) after the carbon fiber is baked, cooling the carbon fiber to room temperature to finish the treatment for the contact end of the surface of the oriented carbon nano tube-modified carbon fiber.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a method for treating the contact end of carbon nanotube modified carbon fiber surface. Background technique [0002] Carbon fiber, as a typical application representative of new carbon materials, is widely used in the manufacture of high-end composite materials due to its excellent mechanical, electrical and chemical stability, and has become a popular choice in many fields, especially including aerospace, lightweight equipment, military industry, etc. The key research object is an indispensable key material for today's advanced manufacturing and advanced equipment. [0003] The surface of carbon fiber is smooth and its chemical activity is low. Affected by this, it is easy to debond from the composite material matrix. For this reason, many technologies represented by improving the surface roughness of carbon fiber have been disclosed one after another. It mainly includes electroch...
