Description

Structural material containing energy and its preparation method and application
Technical field
The invention belongs to new material technology fields, more particularly to a kind of structural material containing energy and its preparation method and application.
Background technique
Efficiently injure be Long-range precision strike basic goal, injuring for weapon relies primarily on using traditional ammunition as core at present The warhead of the heart, therefore develop height and injure one of the core missions that ammunition is promotion long distance precision attack missile.Traditional warhead It is mainly made of metal shell, explosive and corresponding structure member etc., explosive is the energy that target is injured by warhead, to improve Power is injured by warhead, general using realizing by the way of raising dynamite charge amount and unit mass explosive energy, due to by To the limitation of use condition and material horizontal, the loadings of explosive are there are the limit, and the raising of explosive energy density is also very It is difficult.In addition, the sub-fraction that member energy obtained is explosive whole energy is injured in explosive energy release and conversion process, The slightly raising of dynamite charge amount or energy density may not be able to bring the significantly promotion to target Damage effect.Therefore, The raising of warhead damage effects needs to expand new technological approaches.
Prevailing conditions stability inferior is high, but high-speed impact can cause the energetic material frequently referred to reaction of exothermic reaction between component Material (Reactive Materials, RMs) has the reaction material of strong mechanical performance to be known as reaction structure material or the structure containing energy Material.The components such as the fragmentation, cavity liner and shell structure of warhead are made using the structural material containing energy, are driven in explosive charge Member is injured in lower formation, is given by modes such as explosively loading, high speed impacts and is injured transition energy needed for member applies reaction, promotes it Secondary release is reacted between itself constituent element or between constituent element and environment can be, it can be achieved that the igniting of target, igniting and injuring.Contain Can application of the structural material in ammunition be improve ammunition in hand performance a kind of new way (Xu Songlin, this world is clear, bright etc., The mechanical property research of PTFE/Al reaction material.Chinese Journal Of High Pressure Physics, 2009,23 (5): 384 ~ 388.
