论述了3D打印技术在铝基含能材料性能调控方面的应用;分别讨论了3D打印墨水优化和利用3D打印技术优化成型材料的微结构两个方面对含能材料燃速、力学特性等方面的影响。研究发现,在墨水中添加含氟聚合物或可解链聚合物会显著影响铝粉燃烧的初始反应路径,调节其点火和燃烧特性;作为黏合剂在含能材料应用中能够快速释放大量气体产物,抑制铝粉的团聚,是未来黏合剂选择的一种新路径。3D打印含能材料的微结构优化主要利用改变含能材料空间结构、分布梯度和组分的特定结构等方法,提高材料的燃烧效率。从目前已有成果和发展趋势来看,墨水优化与微结构优化相结合将是含能材料制备工艺的未来发展方向。附参考文献94篇。

The application of 3D printing technology in the performance regulation and control of aluminum-based energetic materials were exposited.The effects of 3D printing ink optimization and microstructure optimization on the burning rate and mechanical properties of molding materials were discussed.It is found that the addition of fluoropolymer or detachable polymer in the ink can significantly affect the initial reaction path of aluminum powder and adjust its ignition and combustion characteristics.As a binder in the application of energetic materials,it can rapidly release a large amount of gas products and inhibit the agglomeration of aluminum powder,which is a new path for future binder selection.The microstructure optimization of 3D printing energetic materials mainly utilizes methods such as changing the spatial structure,distribution gradient,and specific structure of components to improve the combustion efficiency of energetic materials.According to the current achievements and development trends,the combination of ink and microstructure optimization will be a potential direction for the manufacture process of energetic materials in the future.With 94 references.
