Project Title: Isotropic Low CTE C-C Composites

Technical Abstract (Limit 200 words)

Low density/reduced mass materials with a low coefficient of thermal expansion (CTE) have many applications in a variety of aerospace systems. Low cost manufacturing is enabling to the utilization of these materials. Carbon-Carbon (C-C) composites meets the low mass requirement, but has an isotropic CTE and is prohibitively expensive. Through the selective use of graphite reinforcements in un;ique architectures along with unique matrix/binder formulations, it is possible to produce C-C composites for less than $50/lb. with an isotropic CTE at or near zero. The concept of low cost low CTE C-C composites has been initially demonstrated. This program will optimize formulation and processing to produce low cost C-C composites with an isotropic CTE at or near zero.

Potential Commercial Applications (Limit 200 words)

In addition to mirror and instrument mounts as well as mirror blanks, isotropic zero to near zero CTE C-C has applications for a plethora of applications in electronics including substrates or boards and anyplace where dimensional control and/or light weight is important, including enginie components.
