摘要 采用溶胶凝胶法制备了纳米铝热剂含能油墨,利用喷墨打印快速成型装置,初步研究了纳米铝热剂含能油墨喷墨打印装药方法的可行性。将纳米铝热剂打印在金属桥膜上,构建平面结构的火工芯片,并进行了点火实验。结果表明:含能油墨可以被金属桥膜点燃,但是不能持续燃烧。将纳米铝热剂打印在半导体桥塞上,测试了在裸露无约束和有管壳约束两种条件下纳米铝热剂的发火特性。结果表明:在相同发火条件下,裸露的纳米铝热剂不能被点燃,有管壳约束的纳米铝热剂被点燃。 Energetic nano-thermites were prepared by sol-gel method, and nano-thermites ink was obtained. Using inkjet rapid prototyping device, the nano-thermites ink was printed on the metallic bridge to construct a planar initiating chip, and then the chip was ignited. The result showed that energetic nano-thermites ink can be ignited, but combustion wasn't sustainable. Meanwhile, the nano-thermites ink was printed on the SCB under constrained and unconstrained situations, respectively. The ignition experiments revealed that the energetic nano-thermites can be ignited under constrained situation, but can't be ignited under unconstrained situation.
