Research on the Relationship between the Impact Explosive Temperature and Mass Ratio of PTFE/Al Reactive Material

The impact explosive temperature of reactive material is not only an important indicator to measure the ability of explosive reaction, but also a required parameter to carry out thermo-chemical calculation. So there is important practical significance to study the impact explosive temperature effect of reactive material. Based on one-dimensional shock wave, thermodynamics and physical chemistry theory, mathematical analysis model of impact explosive temperature vs. mass ratio of the reactive material is established. By MATLAB programming, the curve of impact explosive temperature vs. the mass ratio of PTFE/Al reactive material is received, which can be used to analyze variations. Fitting function equations is obtained by MATLAB CFTOOL. At last, the contrast of original calculation curve with fitting curve validates the appropriateness of the fitting function equations. From the view of impact explosive temperature effect, we suggest that the established model and research method can be applied to the dynamic properties research of other reactive material.
