| 제목 | A Study on the Nonlinear Viscoelastic Properties of PBXs |
| 초록 | Plastic bonded explosive(PBX) is manily composed of the nitramine explosive and the polymer binder. PBX is characterized by high velocity and pressure of detonation, low vulnerability and good thermal stability. Many important applications of PBX require the good mechanical properties and good adhesion between the explosives and the binder. Time depentent compressive properties of composite explosives have been determined by stress-strain curves obtained at different strain rates and temperatures. Both the small deformation and ultimate property can be representes by master curves, which are functions only of the experimental time scale, along with a temperature function. The mechanical properties of adhesion between the binder and explosive particle has been investigated by determining RDS. The interface was observed through SEM. It is supposed that this phenomenon is derived from a strong interaction force between binder molecules and a strong adhesion force between the binder and explosive particles. |
