Abstract Scope |
Due to the risk posed by violently reactive materials such as high explosives, it is often desirable to have access to inert substitutes (“mocks”) that will behave similarly to their explosive counterpart in non-detonative applications. Use of mocks is well-established, but many explosives do not have a mock available that suitably mimics more than one or two properties, if there is a mock available at all. The objective of this work is to identify a robust thermomechanical mock for PBX 9502, an composite of the explosive TATB and a polymer binder, which closely matches a set of priorities (e.g. cost, density), and perform a series of mechanical tests. Target mechanical properties include quasistatic and dynamic response at a range of temperatures. Various strategies and methodologies for identifying and manufacturing potential mock materials will be discussed, along with preliminary data on the mechanical similarities of our new mocks to PBX 9502. |
