Thermal Safety Characterization of HMX, LX-07, PBX 9502, and XTX-8004 in the ODTX System
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Incidents caused by fire and combat operations can heat energetic materials that may lead to thermal explosion and result in structural damage and casualty. Some explosives may thermally explode at fairly low temperatures (< 100 C) and the violence from thermal explosion may cause a significant damage. Thus, it is important to understand the response of energetic materials to thermal insults. The One- Dimensional-Time to Explosion (ODTX) system at the Lawrence Livermore National Laboratory has been used for decades to measure times to thermal explosion, threshold thermal explosion temperature, and to determine the kinetic parameters of thermal decomposition of energetic materials. The kinetic parameters are being used to construct predictive models for thermal safety assessment on systems that use the energetic materials. Samples of different configurations (pressed part, powder, paste, and liquid) can be tested in the system. This report summarizes the results of our recent ODTX experiments on 4 energetic materials from 2016 to 2018: HMX (class 1 and class 2), LX-07 (two densities), PBX 9502 (two densities) and XTX-8004, lot C-639. Extensive P-ODTX testing was also performed on the 4 energetic materials and the results will be summarized in a separate report.
