Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries. ACR has already developed extensive software and hardware capability for solid freeform fabricatio ...

Functionally smart materials, which have to ability to perform both sensing and actuating operations, are being developed to perform many aircraft type of control events. Smart materials, fabricated suing "continuous ferroelectric fibers," are being consider for full flight control of subsonic missiles, as the servoactuator system, specifically, and for active aerodynamic surface cont ...

The goal of this program is to design and fabricate selected liquid rocket engine combustion components. This goal will be accomplished by developing a low-cost, near net-shape technology for fabrication and rapid densification of ablation and oxidation-resistant LRE components for a wide variety of Air Force missions. The material which will be used for this purpose is zirconium diboride/boron ...

Solid Free Forming of monolith and uniform discrete reinforced materials has been demonstrated by fused deposition of heavily loaded slurries. In this program we will extend the fused deposition process to functional gradient material. The composition of material deposited will be controlled by the flow rates of two individual materials that are mixed in a low dead volume head. Thus, it will be po ...

The goal of this program is to develop a low cost, flexible manufacturing method for the production of Cf reinforced composites for ablation-resistant propulsion components for Theater Missile Defense (TMD) concepts. The matrix material selected for demonstration of the technology will be HfC, a material which has demonstrated good oxidation and ablation resistance at elevated temperatures.

The primary objectives of this Phase I effort are to assess the feasibility of developing a p-channel 2-D MESFET and to determine the extent of the significant reduction in power consumption of integrated circuits which may be achieved by utilizing a complementary 2-D MESFET technology. The new FET technology promises to eliminate the Narrow Channel Effect (NCE) which is one of the primary factor ...

This Phase I project has two primary objectives. The first objective is to develop an engineering model of Resonant Tunneling Devices (RTD) to be implemented in AIM-Spice, a commercial software package running under Windows 95/NT. The development of a reliable device model is a prerequisite for the design and production of any semiconductor device technology. The RTD model will be a semi-empiri ...
