Project Title: Rapidly Prototyped Single-Wall, Fullerene Nanotube-Reinforced


Technical Abstract (Limit 200 words)

NASA is seeking rapid prototyping (RP) processes that can produce functional prototypes and working models, which will establish state-of-the-art manufacturing technologies to construct future spacecraft. Single-wall nanotubes are expected to exhibit spectacular mechanical, electronic, and magnetic properties. With such great promise, a logical use of nanotubes is in composites to improve the properties and performance of the matrix material. Lone Peak Engineering (LPE) proposes a RP process to directly produce composites reinforced with single-wall nanotubes. These composites will be used in functional applications as prototypical components or as tools to form other components needed to build future spacecraft.

In this Phase I project, the feasibly of LPE's RP process to build functional nanotube-reinforced composites (NTRCs) will be demonstrated. Two matrix materials will be examined: 1) an epoxy-based resin that will result in composites similar to the pre-pregs that are currently used as tooling at NASA and 2) titanium metal matrix composites, which can be used as functional prototypes and working models.

During Phase II, the RP process will be refined to allow LPE to fabricate pre-preg-like composite tooling. This tooling will be delivered to NASA-Johnson for evaluation in the production of panels for the X-38 spacecraft. Functional titanium-matrix composite prototypes will also be prepared for evaluation in specific NASA-related applications. The tooling and functional prototypes will be delivered to NASA for evaluation in their intended applications at the end of the Phase II project.

Potential Commercial Applications (Limit 200 words)

The commercial applications of this technology lies

in the rapid fabrication of tooling, functional

prototypes, and working models. There is strong

commercial demand functional prototypes with

shorter turnaround times, especially when only

small quantities of parts are ordered. The RP

process can meet this commercial demand for

functional RP components. Industrial sectors

interested in this capability include the aerospace,

medical, sporting goods, transportation, and power

generation industries.
