H-2A launch vehicle general review revealed reduction in strength of thermal insulator on the fairing. Sealant which adheres sheet insulator was found incurable also. Mechanical tests and SEM (Scanning Electron Microscope) observations suggested that incomplete mixing of the raw materials was the reason of lower strength due to degraded uniformity of the insulator. By improving mixing process, well performed, firm insulator was achieved. Evaluation of cure processes proved that alcohol released during insulator cure obstructed hardening of sealant resulting in insufficient cure time. Adequate cure time assured reduced alcohol release and mature vulcanization of sealant. The process was improved based on these findings, and this resulted in more reliable insulator.
