摘要：
The damage process of hydroxyl-terminated polybutadiene(HTPB) propellant/liner adhesive interface was observed by scanning electron microscope(SEM)in situ tension system. The real-time SEM images of deformation and failure for interface were collected. The micro mechanism of deformation and failure of adhesive interface was analyzed combining with the macroscopic stress(σ)-strain(Ε) curve. Results show that the tensile failure process of adhesive interface can be separated into four stages: l inear interval with larger slope(0 ©, 2015, Institute of Chemical Materials, China Academy of Engineering Physics.
