Abstract
The invention mainly discloses an energetic structural material which is formed by mixing and pressing Al powder, KClO3 powder and W powder. The mass ratio of the Al powder to the KClO3 powder ranges from 1.3:1 to 2.2:1, and the weight of the W powder accounts for 30% of the total weight of the Al powder, the KClO3 powder and the W powder. The energetic structural material has enough insensitiveness and is nonreactive in the explosion acceleration process; the energetic structural material has the high density in the striking penetration process, thereby being ensured to have large penetration power and being capable of conducting chemical reaction to release energy so as to increase the capacity for damaging a target; andthe steel target penetration capacity of a liner made of the energetic material provided by the utility model is higher than the steel target penetration capacity of a liner formed by the W powder and the Al powder, and the key problems of reaction energy releasing, inertia, the density and the like are solved.
Description
Technical field
The invention belongs to new material technology field, be specifically related to a kind of containing energy structured material.
Background technology
Containing claiming again, containing energy metallic substance, to refer to a kind of metal or various metals are combined with certain processing method by structured material, can produce the metal-containing polymer of heat-producing chemical reaction under certain condition.Containing can structured material obtaining extensive concern with its huge applications prospect militarily, that utilizes prepared by energetic material efficiently injures warhead, in to target Damage process, not only there is enough kinetic energy puncture target but also can produce violent burning or blast, by additional chemical reaction, discharge the energy that is not less than high explosive magnitude, and the high temperature more than producing 2000 ℃, effectively improved fragmentation and injured the aftereffect of killing and wounding of the kill probability of target internal part and single piece of fragmentation, increased the lethal power of target and lethal radius.Energetic material is mainly made by the metastable material with " class detonation " property.Metastable state reaction material can be lighted a fire and be discharged large energy when high-speed impact target, conventionally two or more chemical substances, consists of, and this class material comprises intermetallic compound, metal-polymer compound and some metastable metallic compounds etc.Realize the breakthrough of energetic material in utilisation technology, must solve its reaction and release the key issues such as energy, inertia and density, be that energetic material enough insensitiveness in explosive acceleration process do not react, in clashing into Penetration, there is higher density and there is certain Penetration to guarantee it, and chemical reaction can occur release energy to increase and injure target capability.
Summary of the invention
The object of this invention is to provide a kind of containing energy structured material, this energetic material is a kind of energetic material that can be applicable to efficiently injure warhead, in clashing into Penetration, there is stronger Penetration, and chemical reaction can occur release energy to increase and injure target capability.
The technical scheme that the present invention realizes above-mentioned purpose employing is: a kind of containing energy structured material, by Al powder, KClO
3three kinds of powder of powder and W powder mix compacting and form, described Al powder and KClO
3the mass ratio of powder is 1.3-2.2:1, and the quality of W powder is Al powder, KClO
330% of powder and W powder three total mass.
Beneficial effect of the present invention
Provided by the invention containing not reacting by structured material enough insensitiveness in explosive acceleration process, in clashing into Penetration, there is certain density, can guarantee that it has larger Penetration, and can there is chemical reaction and release energy, increase and injure target capability, the cavity liner that this energetic material is made is stronger than the ability of the cavity liner penetrating steel target of being made by W and Al powder, has solved reaction and has released the key issues such as energy, inertia and density.
Accompanying drawing explanation
Fig. 1 is testing apparatus schematic diagram of the present invention;
Reference numeral: 1, cavity liner, 2, explosive, 3, detonating primer, 4, steel target.
Embodiment
Containing an energy structured material, by Al powder, KClO
3three kinds of powder of powder and W powder mix compacting and form, described Al powder and KClO
3the mass ratio of powder is 1.3-2.2:1, and the quality of W powder is Al powder, KClO
330% of powder and W powder three total mass.
Principle of the present invention: provided by the invention containing not reacting by structured material enough insensitiveness in explosive acceleration process, in clashing into Penetration, there is certain density, can guarantee that it has larger Penetration, and chemical reaction can occur release energy, increase the ability of injuring target.
Below in conjunction with concrete test example, the present invention will be further described:
simultaneous test
Test materials:
By energetic material provided by the invention, through colding pressing, be pressed into containing can cavity liner, and be mixed and made into pure metal cavity liner by two kinds, W and Al powder; The shape of two cavity liners, size and quality are all identical, are the round pie of central dip, and circular diameter is 30mm;
Two identical steel targets 4;
Two groups of density are 1.45 g/cm
3tNT explosive 2 and detonating primer 3;
Two identical explosive anchors.
Test method:
Steel target 4, in the vertical fixation in position apart from explosive anchor certain distance, and is placed on explosive 2 on explosive anchor, and one end that explosive 2 is equipped with detonating primer 3 is away from steel target 4.Cavity liner 1 is arranged on explosive and with steel target 4 and is oppositely arranged.
Install containing can cavity liner one group be test group, one group that pure metal cavity liner is installed is control group, fired charge, observes and measures the Penetration Depth on steel target 4.
Experimental result: only have the vestige of a penetration on the steel target 4 of control group, almost there is no Penetration Depth, presenting an outside bore on the steel target 4 of test group is Ф 20mm, and the degree of depth is the vestige of the penetration of 10 mm.
