Correlation between solid propellant failure and interface debonding in solid rocket motors
2022, Polymer TestingCitation Excerpt :The function of the liner layer is to achieve good bonding between the propellants and the insulation [3]. Therefore, solid propellants and their interface bonded to the liner layer are two weak parts for the integrity of solid rocket motors [4,5]. The integrity analysis to determine the ultimate failures of the propellants and the propellant-liner interfaces is very important for the prototype design and health condition evaluation of SRMs [6,7].
Crack propagation velocity and fracture toughness of hydroxyl-terminated polybutadiene propellants: Experiments and simulations
2021, Engineering Fracture MechanicsCitation Excerpt :Cracks may propagate rapidly during the launch and cause an unexpected rise in gas pressure that may affect the ballistic performance, even lead to a catastrophic accident. The more specific significance of investigating the fracture characteristics of solid propellants can be found in Ref. [2]. In previous studies, Liu [3–5] studied the fracture characteristics of a highly filled polymeric material at different tensile rates and gave a power-law relationship between the stress intensity factor and crack growth rate.
