Benefits of technology

"The present invention is a carbon nanotube-infused fiber, where the carbon nanotubes are physically or chemically bonded to the parent fiber. This bond is strong and robust, and the carbon nanotubes effectively function as a replacement for conventional sizing materials. The carbon nanotubes are synthesized on the parent fiber by applying a nanotube-forming catalyst and heating the fiber to nanotube-synthesis temperature. The resulting fiber exhibits the characteristic properties of carbon nanotubes, such as exceptional mechanical strength, low to moderate electrical resistivity, and high thermal conductivity. The carbon nanotube-infused fiber can be tailored or engineered to meet the requirements of a specific application, making it a versatile and valuable tool for improving the properties of fibers."

Problems solved by technology

Because of the strong van der Waals attraction between the already-formed carbon nanotubes, it is extremely difficult to separate them to apply them directly to the fiber.

example

[0099]A CNT-infused carbon fiber was formed in accordance with the illustrative embodiment. A current was passed through carbon fiber (the parent fiber) to heat it to approximately 800° C. to remove epoxy sizing material. The fiber was then cooled to room temperature and left clamped between electrodes. A ferro-fluid catalyst was applied to the fiber using an aerosol spray technique. The fiber was allowed to dry and the chamber was closed, evacuated and filled with argon. A current was passed through the carbon fiber again to heat it to approximately 800° C. for carbon nanotube synthesis. A carbon plasma was generated from acetylene precursor using 13.56 MHz microwave energy using an atmospheric pressure plasma jet. The carrier gas in the plasma jet was helium at 20 standard liters per minute (slm) and the argon was provided at 1.2 slm. The plasma jet was fixtured to a robotic motion control system allowing the plasma jet to move over the length of the fiber at a speed between 6 and...

Abstract

A carbon nanotube-infused fiber and a method for its production are disclosed. Nanotubes are synthesized directly on a parent fiber by first applying a catalyst to the fiber. The properties of the carbon nanotube-infused fiber will be a combination of those of the parent fiber as well as those of the infused carbon nanotubes.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 11 / 619,327, filed on Jan. 3, 2007.FIELD OF THE INVENTION[0002]The present invention relates to carbon nanotubes and fibers.BACKGROUND OF THE INVENTION[0003]Fibers are used for many different applications in a wide variety of industries, such as the commercial aviation, recreation, industrial and transportation industries. Commonly-used fibers for these and other applications include cellulosic fiber (e.g., viscose rayon, cotton, etc.), glass fiber, carbon fiber, and aramid fiber, to name just a few.[0004]In many fiber-containing products, the fibers are present in the form of a composite material (e.g., fiberglass, etc.). A composite material is a heterogeneous combination of two or more constituents that differ in form or composition on a macroscopic scale. While the composite material exhibits characteristics that neither constituent alone possesses, the constituents...
