Embodiment Construction

[0030]The present invention allows for the development of composite materials reinforced with single- and multi-walled nanotubes in order to produce materials that are lightweight, possess high strength and stiffness, and show improved composite toughness. A complementing aspect of the invention allows for tailoring the thermal and electrical properties of these nanotube derived materials, and processing and manufacturing parts using them.

[0031]The problems with infiltration of a metal with the nanotubes can be solved by fluid mixing that occurs in the electromagnetic levitation process. The invention addresses embedded nanotube dispersion, wettability, adhesion, and alignment issues in a matrix of metals. Functionalizing of the metallic and semiconducting nanotubes along the tube wall can be used to ensure wetting. A series of metals and alloy matrices including aluminum, copper, and tin have been processed with nanotubes to investigate the thermophysical properties of the melt mix...

Abstract

The present invention relates to fullerene, nanotube, or nanofiber filled metals and polymers. This invention stems from a cross-disciplinary combination of electromagnetic and acoustic processing and property enhancement of materials through fullerene or nanofiber additives. Containerless processing (CP) in the form of electromagnetic field enduced and / or acoustic mixing leads to controlled dispersion of fullerenes, nanotubes, or nanofibers in various matrices. The invention provides methods of mixing that highly disperse and align the fullerenes, nanotubes, or nanofibers within the matrices of metals and polymers. The invention provides new compositions of matter and multifunctional materials based on processing, composition, and degree of in situ processing.

Description

[0001]This invention was made with Government support under NSF Grants Nos. CTS-9312379 and DMR-9357505 awarded by the National Science Foundation and the Texas Advanced Technology Program, TATP Grant No. 003604-056. The Government may have certain rights in the invention.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates in general to the materials science field of composites, and more particularly to composites of dispersed nanotubes or nanofibers in a desired matrix. Even more specifically the present invention relates to a composite of highly dispersed or aligned fullerene nanotubes within a pure metal or metal alloy matrix and the process for making the same. The invention comprises at least three aspects: the composition of the composite material, the process for making the composite material, and an improved method for mixing or dispersing nanotubes in a matrix.[0004]The invention relates to fullerene, nanotube, or nanofiber filled m...
