Additionally, they summed up the microstructural evolution during the thermal expansion process, and evaluated the consequential effects of thermal growth on the total efficiency of these explosives.Innovations in Thermal Expansion Control”More attention was paid to the influencing elements of thermal expansion and control techniques. Obviously, developing a new structure of negative thermal expansion binding system, through the design of unfavorable thermal growth polymers or fillers and positive expansion TATB crystals, can decrease the direct growth coefficient of PBXs,” explained the studys lead author Cong-mei Lin.”The authors believe that the development of the structural design of TATB and binder system and the application of unfavorable thermal growth functional materials will bring new opportunities to reduce the thermal growth of TATB-based PBXs and enrich the adjustment strategies of energetic composites.Reference: “Research development in thermal growth qualities of TATB based polymer bonded dynamites” by Cong-mei Lin, Liang-fei Bai, Zhi-jian Yang, Fei-yan Gong and Yu-shi Wen, 16 September 2023, Energetic Materials Frontiers.DOI: 10.1016/ j.enmf.2023.09.003 The study was moneyed by the National Natural Science Foundation of China.
