Abstract
This paper describes an evaluation of the proton irradiation effects on the
thermal characteristics of a pyrolytic graphite sheet (PGS), which has characteristics
of high thermal conductivity, light weight, and flexibility, in order
to apply this material to an advanced spacecraft thermal control device, the
reversible thermal panel (RTP). The results show slight changes in the inplane
thermal diffusivity and total hemispherical emittance of the PGS for
2.0MeV proton irradiation. An RTP prototype model based on the PGS
was designed and fabricated, and its thermal performance was evaluated. The
effects of changes in thermal characteristics of the PGS on the thermal performance
of the RTP were also discussed.
