QJ 2038.2-1991 Test method for interface bonding strength of solid rocket motor chamber- Shear method
1 Subject content and application scope
This standard specifies the specimen preparation, test procedure, and test result processing of testing the combination shear bonding strength of the chamber case, insulation, liner, and propellant of solid rocket motor (hereinafter referred to as motor).
This standard is applicable to testing the combination shear bonding strength of the motor chamber case, insulation, liner, and propellant, as well as the testing the shear bonding strength of the motor chamber case with fiber winding, and metal parts are used instead of fiber winding parts during specimen production.

QJ 2038.1 Test method for interface bonding strength of solid rocket motor chamber - Unstick test
3 Test principle
The insulation, liner, and propellant with the same area are bonded between two parallel metal plates, and the tensile force is applied in the direction parallel to the bonding surface to measure the stress when the specimen reaches shear failure.
