Abstract

Explosives are used in a wide range of industrial, military and civil applications, and their behavior under extreme temperature conditions is a key aspect for safety and reliability. The present study analyzes the influence of extreme temperatures on the stability and reactivity of explosive materials, highlighting the critical factors that can lead to degradation, changes in sensitivity or accidental triggering. In the research, experimental methods and numerical modeling were used to evaluate the thermal behavior of conventional and advanced explosives, including temperature-sensitive organic compounds and metallic explosives. The tests were carried out in controlled environments, covering temperatures from -25-C to over 55-C, with the aim of determining the effects of prolonged exposure to extreme conditions on the chemical and physical stability of the materials. The results obtained indicate a direct correlation between the exposure temperature and changes in the molecular structure of explosives, influencing the detonation velocity, shock sensitivity and deflagration behavior. The study also highlights the risks associated with the storage and transportation of these materials in regions with extreme climates, emphasizing the need to implement protective measures, including the use of stabilizing additives and heat-resistant containers. Therefore, this analysis contributes to the development of advanced risk management strategies associated with the use of explosive materials in environments with variable temperatures, with significant implications for the defense industry, mining and civil safety.
