Filed:

Apr 10, 2000

Appl. No.:

09/546081

Inventors:

Frederick James Herman - Fort Worth TX

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

D01F 912

US Classification:

4234473

Abstract:

The present invention provides methods and systems for net shaped manufacturing using carbon nanotubes. Generally, an automatic control unit is used to place reaction units in the proper location to produce a component part of carbon nanotubes in a predetermined configuration. The reaction units include a carbon vaporization unit, a carbon feed/injection unit and a gas pressure/temperature control isolation unit. The carbon feed/injection unit advantageously operates to inject carbon based materials (e. g. , graphite powder, solid graphite or carbon based gas) into an reaction area at a predetermined rate in which the carbon vaporization unit provides energy capable of dissociating carbon atoms from the injected carbon based material to produce a predetermined concentration of carbon vapor within the reaction area. The gas pressure/temperature control isolation unit operates to control the pressure and temperature of the reaction area to promote the growth of carbon nanotubes.

Inventors:

Frederick J. Herman - Fort Worth TX

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H02P 904

US Classification:

290 1R

Abstract:

A system and method for supplying electricity for use with a host device. The system includes a structure and an interface. The structure includes an array of single-walled carbon nanotubes arranged with respect to a matrix. In operation, the system receives a force stimulus for facilitating piezoelectric generation of electricity. In particular, the array receives the force and piezoelectrically generates electricity therefrom. The array is electrically coupled with the interface. The interface allows the structure to supply electricity to electrical devices that are coupled to the interface.

International Classification:

B23B 9/00

US Classification:

428408, 428913

Abstract:

A structure arrangement and method for the protection of a host system against an impacting ballistic element and for providing ease of mobility. The structure arrangement includes a composite. The composite includes a matrix and a multiplicity of single-walled carbon nanotubes. The single-walled carbon nanotubes are arranged with respect to the matrix so as to define an array for engagement with an impacting ballistic element.

Abstract:

A system for fabricating a free form structure of a composite material including carbon nanotubes. The system includes a discharge assembly and a composite formation device operatively linked with the discharge assembly. The discharge assembly dispenses a fusing agent such as for example a high energy density emission, a laser emission or a particle beam emission. The composite formation device includes a composite generator and an arranger in operative engagement with a composite generator. The composite generator engages with the fusing agent so as to create a composite nodal element. The composite nodal element includes a matrix and a multiplicity of fibers formed of carbon nanotubes dispersed throughout the matrix. The arranger positions one node relative to another to define the free form structure.
