Description

Structural material containing energy and its preparation method and application
Technical field
Contain energy structural material and its preparation method and application the invention belongs to new material technology field, more particularly to one kind.
Background technology
Efficiently injure be Long-range precision strike basic goal, injuring for current weapon relied primarily on traditional ammunition as core The warhead of the heart, therefore it is one of core missions of lifting long distance precision attack missile that development height injures ammunition.Traditional warhead Mainly it is made up 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, is typically realized by the way of dynamite charge amount and unit mass explosive energy is improved, due to receiving To the limitation of use condition and material horizontal, there is the limit in the loadings of explosive, and the raising of explosive energy density is also very It is difficult.Additionally, the sub-fraction that first energy for being obtained is explosive whole energy is injured in explosive energy release and transfer process, The slightly raising of dynamite charge amount or energy density might not bring the significantly lifting 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 trigger the energetic material of exothermic reaction between component to be frequently referred to reaction Material（Reactive Materials, RMs）, there is the reaction material referred to as reaction structure material or the structure containing energy of strong mechanical performance Material.The parts such as fragmentation, cavity liner and the shell structure of warhead are made using the structural material containing energy, are driven in explosive charge Unit is injured in lower formation, and the transition energy injured needed for unit applies reaction is given by modes such as explosively loading, high speed impacts, promotes it Reacted between itself constituent element or between constituent element and environment it is secondary release can, be capable of achieving to the igniting of target, ignite and injure.Contain Application of the energy structural material in ammunition is a kind of new way for improving ammunition in hand performance（Xu Songlin, this world is clear, bright etc., The mechanical property research of PTFE/Al reaction materials.Chinese Journal Of High Pressure Physics, 2009,23 (5):384 ~ 388. Yang Yi, Zheng Ying, king It is female, high density active material and its damage effect progress research, Arms Material scientific and engineering 2013,36 (4): 81- 85.Song Lei, Li Baofeng, Chen Hao, USN's demonstration improve warhead brisance with " high density active material ", and equipment refers to 2011,49：32-33.）.
Containing can the external force born when in use of structural material mainly there is explosive to drive when compression, flight unloading when drawing Compression when stress, impact are slowed down and penetrate tension when target is unloaded, thus containing can structural material generally require and have Following characteristics：（1）With sufficiently high intensity, on the one hand ensure that material can be used as structural member such as explosive assembly casing, separately On the one hand the integrality in explosion driving and penetration object procedure is ensured；（2）With suitable reaction latent heat and latent heat treatment Ability, it is ensured that Energy Release during high-speed impact；（3）Moderate density, it is ensured that the indispensable penetration property of material.
The structural material containing energy of above-mentioned requirements is met to obtain, the Chinese patent of Application No. 201510733993.8 is carried A kind of preparation method of energetic material is gone out, the method prepares the structural material containing energy, uses using the method for molding, sinter molding The Al/W/PTFE energetic materials that the method is obtained are compared to traditional Al/PTFE（Al:26.4wt%；PTFE:73.6wt%）Containing energy Material is greatly improved in terms of compression strength and density, and the threshold of reaction of energetic material also increases.But such material Material tensile strength is relatively low, is usually no more than 30MPa.
The Chinese patent of Patent No. 201410176443.6 propose it is a kind of containing can structural material, the material by Al powder, KClO3The three kinds of powder mixing compactings of powder and W powder are formed, and material enough insensitiveness during explosive acceleration do not react, and have Larger Penetration, and chemical reaction can occur release energy, target capability is injured in increase.But the material is using cold after mixed powder Molded, the strength of materials is mainly by the mechanical interlocking between powder, and intensity is relatively low.
The Chinese patent of Application No. 201610044485.3 proposes a kind of structural material fragmentation containing energy, and the material is by receiving Cold moudling is obtained after rice aluminium powder, transition metal oxide, oxidant, ferrocene, high explosive and hybrid adhesive mix, and is utilized The material prepare containing can fragmentation energy density is high, the ability that has a safety feature, easily triggers and set on fire is strong, when explosive drives not Strong chemical reaction can occur in meeting immediate response, but Penetration and high heat is released, and it is vehement to generate high temperature Heat, the product with mobility.The intensity of the material is mainly determined that intensity is still relatively low by binding agent.
The Chinese patent of Patent No. 201110440556.9 and the Chinese patent of Application No. 201510606975.3 are carried Two kinds are gone out and have prepared method of the tungsten zirconium alloy containing energy structural material, the material prepared using the method has had relatively good power Performance is learned, but the material gives off energy mainly by zr element with the oxygen effect in environment, and latent heat treatment ability is poor, therefore To fuel oil ignite and the blasting effect of explosive is general, it is necessary to be possible under given conditions.
As can be seen here, at present open report containing can structural material combination property also have apart from actual demand it is certain away from From.
