Vacuum thermal performance of adhesive-backed polyimide film heaters
摘要
Abstract
To address the low bonding efficiency,poor bonding consistency,and blister-related failures of conventional silicone-rubber-bonded polyimide film heaters in spacecraft thermal control,rapidly applicable pressure-sensitive adhesive(PSA)-backed heaters are planned for implementation in current batch-produced satellites.A PSA-backed polyimide film heater based on an acrylic-ester crosslinked system was developed,and vacuum thermal tests under three typical operating conditions were conducted.The failure thresholds and thermal performance of the PSA-backed and conventional silicone-rubber heaters were quantitatively compared using a stepped-temperature heating scheme.The results indicate that the PSA-backed heater exhibits higher failure thresholds and improved interfacial stability at both room and low temperatures,and features faster thermal response and smaller temperature fluctuations.It operates stably from-80℃to 180℃and can sustain continuous operation for over 24 h without failure under limit currents of 0.9-1 A.These findings demonstrate that the PSA-backed polyimide film heater offers strong thermal adaptability for aerospace applications and can effectively replace the traditional silicone-rubber bonding process,providing an efficient technical solution for the production of spacecraft thermal control components.关键词
