RÉSUMÉ

The paper presents work conducted on manufacturing, analysis, and testing of an innovative all-carbon fiber-reinforced plastic thermal radiator with embedded metallic tubing for spacecraft application. The developed configuration solves the mismatch in thermal expansion between the embedded metallic tubing and the carbon structure. It can be used as a condenser or radiation heat sink for either two-phase or single-phase heat transportation systems. For this purpose high-conductivity carbon fiber has been employed in the radiating face sheet. Thermal test results for a demonstration panel showed good agreement with analytical prediction. The new radiator configuration exhibits a weight saving of about 33% compared to a currently used all-aluminum radiator panel. The technology is intended for use in future communication and scientific satellites.
