The Influence of Temperature on the Bonding Strength of the Interface

Abstract

In order to study the effect of temperature on the bond strength between the propellant and the lining interface, this paper designed a temperature test for the bonded test piece, and conducted a uniaxial tensile test and a stress relaxation test on the test piece. At the same temperature level, the maximum load on the specimen increases with the increase of strain. Under constant strain conditions, the stress on the bonding interface of the test piece gradually decreases with increasing temperature.
