Abstract
The paper deals with the feasibility study and use of advanced composite materials in the Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) program's field-test equipment. Emphasis is placed on thermal expansion in the optical test-equipment structure under elevated-temperature conditions. A design approach using a low-CTE graphite/epoxy composite for the optical bed is considered, and based on several constraints, four basic design approaches are evaluated: honeycomb, separated plate, machine solid, and thin solid. A prototype system is covered, and the test results of coupon samples of the composite baseplate material indicate that CTE is less than 1 ppm/deg C over a wide temperature range.
