Problems solved by technology

In terms of improving the mechanical properties of explosives, the metals generally added cannot significantly improve the mechanical properties of explosives.
Especially in the field of military use, the poor mechanical properties of explosives will lead to premature and false explosions during storage, transportation and launch of ammunition, resulting in irreparable losses in life and property.

Abstract

The invention discloses a high-strength titanium-based fiber explosive. The high-strength titanium-based fiber explosive is characterized in that titanium fibers or titanium alloy fibers are added to a single substance explosive or a mixed explosive as a metal additive, wherein the fibers can be titanium fibers, and also can be titanium alloy fibers or a titanium fiber and titanium alloy fiber mixture. The high strength characteristic of the titanium fibers and the titanium alloy fibers are fully used to improve the mechanical performances of the titanium-based fiber explosive, so the safety of the explosive in the production, storage and transportation process is greatly enhanced, and the volume energy density of the explosive is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of energetic material and explosive manufacturing, and in particular relates to a high-strength titanium-based fiber explosive. Background technique [0002] In the modern history of mankind, explosives have played an irreplaceable role in military and civilian use. However, although explosives have been developed for many years and have made great progress, they still need to be improved in some aspects. For example, how to increase the energy of explosives in a limited volume to improve the efficiency of explosives, how to improve the mechanical properties of explosives so as to improve the safety of explosives during production and transportation. In order to increase the energy density of explosives, the method that countries in the world have generally adopted is to add aluminum powder to explosives. The addition of aluminum powder can increase the detonation heat of explosives, the energy of air bubb...
