墨水直写增材制造技术及其在含能材料领域的研究进展

系统介绍了墨水直写(DIW)增材制造技术及其在含能材料领域的应用,重点综述了近年来DIW技术在亚稳态分子间复合物(铝热剂、铝-氟聚物)、复杂异型火炸药装药结构(固体推进剂装药、炸药装药)及火工品药剂中的研究进展,并提出与之相关的机遇和挑战。指出DIW技术在一定程度上能够弥补传统装药技术的不足,在新型多孔/特殊结构装药和能量密度递变的火炸药装药研发与制造方面极具开发应用潜力,未来可进一步加强增材制造火炸药配方应用基础研究、光-热协同固化体系研究以及弹药壳体-装药一体化制造等方面的研究,为我国新型、高精度战略武器装备的发展提供新思路与技术途径。

Direct Ink Writing Technology for Additive Manufacturing and Its Research Progress in Energetic Materials

The direct ink writing(DIW)technology and its application in energetic materials was systematically introduced.Recent research progresses and applications of DIW technology were emphasized,including metastable intermolecular composites(thermite,aluminum-fluorine polymer),propellants and explosives grains with complex structure,and pyrotechnics.The main relevant challenges and the opportunities of DIW technology were also proposed.DIW technology covers the deficiency of traditional charge technology to a certain extent,and it has great application potential in the research and development of new porous charge/charge with special structure and explosive charge with variable energy density.In the future,it is proposed that the research on additive manufacturing explosive formula for application,the photothermal co-curing matrix,and the integrated manufacturing of ammunition with cased and charge should be enhanced.Thus,new ideas and technical approaches for the development of new and high-precision strategic weapons and equipment in China will be provided.
