Abstract

Abstract: In areospace industry, different kinds of elastomeric materials have been used in low-cost, light weight diaphragms and bladders in hydrazine propellant tanks. The compatibility of a new kind of vulcanized rubber compound 1803-1 with hydrazine propellant is studied experimentally, including immersion test, calalytic decomposition test and penetration test. The experiment process and test data are given about the permeation rate, mass change rate, volume change rate and other mechanical properties. The results show that most of the properties of material 1803-1 after compability test comply with the requirements of Chinese national standard. Rubber compound 1803-1 provides a reference when selecting the material for diaphragm tank bladders.
