Proposal Number:

15.01-5960

Project Title:

Vanasil Ultra Light Composite

Application to Mirrors (VULCAM)

Technical Abstract (Limit 200 words)

Vanasil, a metal matrix composite, has: 3 times the

microyield to weight ratio of beryllium; 10 times the

thermal conductivity of silicon carbide;

homogeneous optical surfaces, no moisture

sensitivity, nor thermal cycling problems, unlike

graphite epoxy; thermal expansion which matches

optical platings and coatings; non-hazardous,

non-toxic, unlike beryllium; and fabrication

technology which allows optimum lightweight

structures. Vanasil can be formed into complex

shapes by casting, and is low cost. Our Phase I

SBIR program will explor Vanasil optics by

fabricating hardware test items. Our team will

perform CTE testing at 30°K and optical testing.

Potential Commercial Applications (Limit 200 words)

A new option for ultra lightweight optics with a

unique set of properties will provide NASA a wider

range of choices. This option is potentially the

lightest weight of any known procedures. The low

cost, easily manufactured structures have

commercial potential for optical metering structures

as simple as optical breadboards and as complex as

any.
