"The rise of next generation electronics depends on advances in microelectronic packaging materials. Power, frequency, and functionality are increasing while cost, size, and margin for error are declining. Military and commercial electronics are reachingperformance limitations since conventional CTE controlled heat sink materials are unable to keep pace with emerging cooling requirements. Graphi ...

"Mg alloys reinforced with high modulus graphite fibers have nearly 1.5 times the specific stiffness of beryllium. Since the EKV sunshade is a stiffness critical application, a sunshade manufactured from graphite fiber reinforced magnesium could weigh athird less than the current Be design. Using MMCC's net-shape Advanced Pressure Infiltration Casting (APICT) process, the sunshade would cost hal ...

"This proposal shows how innovations in producing a family of CTE controlled, high thermal graphite aluminum composites will reduce manufacturing costs and improve system performance for specific BMDO, Navy, and commercial applications. Technologiesdeveloped by a graphite fiber producer, paper textile manufacturer, and metal composites foundry will create a superior thermal management material id ...

"Manufacturing technology development and integration of MMCC's 3- DPT, Tool-Less MoldT and Advanced Pressure Infiltration(APICT) technologies are proposed. Investment casting of preforms printed directly from a CAD or laser file and subsequent pressureinfiltration will enable parts to be manufactured without the added expense of tooling development. With investment materials being recycled and ...

"This proposal considers the potential of direct casting of micro channel cryocooler regenerators. Currently, cryocoolers use regenereators made of packed spheres, which decrease the efficiency of the regenerator and, of course, the cryocooler itself.This is an important issue when considering placing cryocoolers on satellites and the cryocooler itself utilized almost half of the power supply. T ...

"Increasingly demanding requirements for satellite electronics make it more difficult to effectively dissipate heat. One attractive means for managing spacecraft thermal environments is use of heat pipes to passively transfer heat to radiator panels. Weightis a major consideration, so composite materials are desired to replace metallic components. Carbon-carbon composites are used in radiator pane ...

RESEARCH IS DIRECTED AT TECHNIQUES TO IMPROVE SURFACE MORPHOLOGY IN SILICON ON INSULATOR (SOI) WAFERS PREPARED BY ZONE MELTING RECRYSTALLIZATION (ZMR). THE THREE AREAS OF PRIMARY IMPORTANCE IN IMPROVING THE SURFACE MORPHOLOGY OF ZMR PROCESSED WAFERS ARE: SLIP, BOW AND WARP, AND SURFACE SMOOTHNESS. SLIP IS CAUSED BY THERMALLY INDUCED STRESS THAT RESULTS FROM THE TEMPERATURE GRADIENT IN THE MELT ZON ...
