ABSTRACT
This paper describes a feasibility investigation for developing posite materials
with integrated active thermal control and control system electronics for space applications. The
materials were also designed to provide mass-effective shielding against space radiation.
Graphite-posites with integrated variable emissivity solid state electrochromic tiles
and impregnated with materials for enhanced radiation shielding were fabricated. The tiles were
electrically connected to a Kapton panel which was bonded to posite and incorporated
conductor traces for electronics. Key emissivity, radiation (proton) attenuation, and mechanical
property measurements were made on the posite structure. L
