NASA SBIR 01-1 Solicitation

FORM 9B - PROPOSAL SUMMARY


PROPOSAL NUMBER: S2.05-9452 (For NASA Use Only - Chron: 012547 )
PROPOSAL TITLE:
A Graded Density SiC Foam for Lightweight Optics

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Lightweight silicon carbide optics and structures are extremely important to explore the Structure and Evolution of the Universe. State-of-the-art SiC is too heavy, contains other phases which interfere with producing an acceptable optical surface and is anistropic causing distortions with temperature excursions. In this program a functionally graded density isotropic silicon carbide foam will be formed insitu with a unique high density isotropic SiC structure which has a skin of defect free silicon carbide that can be polished ultra-smooth. The functionally density graded isotropic SiC foam structure containing no other phases will be utilized to produce SiC optics with an areal density less than 1 kg/m2. Sample optics will be delivered to NASA.

POTENTIAL COMMERCIAL APPLICATIONS
The commercial potential in addition to lightweight optics for NASA are similar optics for defense systems and some commercial applications. The density gradient SiC foam has a variety of commercial applications as high temperature insulation and structures.
