ACCOMPLISHMENTS
- Designed and produced Gr/Al
radiator panel with built-in heat-pipe housing
- Demonstrated substantial weight
and thermal performance over baseline radiator components.
Electronic substrate provided 10% reduction in weight and 50% improvement
in performance. Radiators provide a 50% improvement
in weight and/or performance
- Designed, produced and demonstrated
substantial benefits in terms of heat removal and weight for Gr/Al
as a substrate for electronics
|
COMMERCIALIZATION
- Commercial sales for MMC substrates
for electronics will be over $40K for 1997
- Two new jobs were created
- Army funded a program for $550K
to place inserts in MMC components
|
GOVERNMENT/SCIENCE
APPLICATIONS
- Gr/Al MMCs have application
in dimensionally stable spacecraft structure and optical platforms,
and they have thermal management application in gas turbines
and rocket engines
- Use of these MMCs as a substrate
in electronic products will reduce cost and improve reliability
of radars, satellites, and other electronics intensive systems
- Samples of MMC electronics substrates
are being supplied to government prime contractors for evaluation.
Keen interest has also been expressed by aerospace contractors in
MMC radiators
