助剂对熔铸炸药力学性能改善的研究进展OA

The research progress on modifying the mechanical properties of melt-cast explosives was systematically reviewed,with an emphasis on investigating the mechanisms and application effects of four different types of mechanical modification addi-tives:fibers,nanoparticles,crystals,and polymers.Research has demonstrated that various additives can improve the me-chanical properties of melt-cast explosives in different pathways,but they also have limitations.For instance,while fiber modi-fiers can enhance compressive strength,they can also easily result in a decrease in tensile strength and limited process adapta-bility.Nanoparticle additives still face challenges in dispersion uniformity and interface mechanism.Crystalline additives are ex-pensive,and the regulatory mechanism for multi-component system is still unclear.By contrast,energetic thermoplastic elasto-mers(ETPEs)are the most promising additives owing to their superior integrated performance,which includes not only the a-bility to achieve toughness and desensitization through structural design but also good process adaptability and recyclability.In order to advance the development of melt-cast explosives in the direction of high safety,long life,and sustainability,future re-search should concentrate on developing new ETPE systems with a wide temperature range adaptability,excellent process com-patibility,high energy-low sensitivity synergy,environmental durability,and intelligent response functions,as well as promo-ting their green synthesis and recycling melt-cast.With 93 references were attached.
