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 ...

Carbon-Carbon components, initially developed for the aerospace industry, have experienced minimal commercialization over the past decade due to cost constraints. C-C composites are excellent candidates for a wide variety of components such as automotive clutches, brakes, and liners, due to its friction and heat transfer characteristics. Recently, within the past five (5) years, new C-C processing ...

The GAO has reported to Congress that the loss due to fraudulent health care activity amounted to an estimated $84 billion in 1992. The ability to detect fraud and abuse is critical to the reduction of health care costs. The claims processing system will soon undergo rapid change with the introduction of rapid payment transaction processing systems. The emphasis on rapid turn around combined with ...

Although great strides have been taken to generate and render problem geometries using computer automated design packages, as well as advancements in the the development of computational electromagnetics codes to solve Maxwell's equations, the link between the two is still very weak. Practical geometries have complex geometric features, abrupt changes in electromagnetic constitutive parameters, an ...

The objective of this proposal is to demonstrate the fabrication of ceramic core/composite skin structures using liquid infiltration techniques. The core will be porous alumina rods or tubes and the composite skin will be fabricated via infiltration with alumina sol of an aluminosilicate fabric wrapped around the core. Heating for drying and sintering will be accomplished using both conventional f ...

The objective of the proposed SBIR program is to develop and commercialize high-temperature optical sensors using sapphire fibers for process control feedback in the fabrication of titanium-based metal matrix composites. Sapphire fiber interferometers will be designed to map the internal distribution of strain and temperature in titanium matrices durng processing, to optimize processing so that re ...
