Abstract
The invention discloses a resilient bomb-resisting mixed composite material. The resilient bomb-resisting mixed composite material is characterized by structurally comprising five layers, namely, a surface layer, a collision layer, an energy absorption layer, a built-in resilient layer and a resistance layer. The surface layer is made of adamantine spar or silicon carbide or boron carbide elements. The collision layer is made of TC4 titanium alloy or a fibrous composite. The energy absorption layer is made of through-hole foam metallic aluminum or silicone rubber foam sheets. The built-in resilient layer is made of silicone rubber or natural rubber and permeates the bottom of the energy absorption layer. The resistance layer is made of the TC4 titanium alloy or the fibrous composite. The five layers are bonded through an adhesive agent, wherein the surface density ranges from 60Kg/m<2> to 90Kg/m<2>. The bomb-resisting material with the composite structure has the advantages of being low in volume weight, high in bomb resistance and capable of resisting multiple bombs, thereby being capable of being used as a protective material for resisting armor-piercing incendiaries with small and medium calibers being 7.62mm or above and being used as the deck of a naval ship and a shield.
Description
Technical field
Patent of the present invention relates to a kind of bullet resistant material, especially relates to a kind of anti-bullet hybrid composite with resilience function.
Background information
In modern war, bulletproof armour material is basis of indispensable existence, is one of key technology of military weapon.Take air force as example, along with the continuous enhancing of ground air defense strength, the military secret of attacking is over the ground faced with powerful ground firepower, so must equip advanced bulletproof armour material, to improve its anti-bullet survival ability.From the Li Sheng of armour material, develop, from traditional metal material (steel, aluminium), advanced ceramic material, composite (Polymers, Metal Substrate, ceramic base) till now, armour material is always towards light weight, efficient future development, the light weight of armor system, efficiently most important concerning improving military secret, tank and armored vehicle and combatant's mobility, attack, battlefield viability.Metal is the material of modern armoring main use, from ordinary steel plate armour, develops into glass hard steel plate armour, Dual Hardness Steel composite armour and even titanium alloy armor, and its protective capacities improves constantly.Metal bullet resistant material plays an important role for the protection of tank, warship, panzer etc. and protects for the nearly body of military secret and human body, because density is larger, therefore can affect tactical qualities performance.The bulletproof ceramic, bulletproof composite material occurring be subsequently with its lighter quality and the excellent ratio of performance to price, and in various fields, replaced metal armor gradually.
Multiple layer combination protection is as the application of existing nearly decades of energy-absorbing decompressor, both at home and abroad the performance of multilayer proofing result is is also analyzed and researched from different perspectives, as Guruprasad etc., everybody has proposed a kind of novel energy absorption device, under Explosion Loading, its performance has been carried out analyzing and has discussed; The people such as Holmquist, carrying out in the research of material constitutive model, analyze the problem of bullet penetration multilayer dielectricity, the impact of the damage and failure of mainly having considered multilayer dielectricity target on penetration; The fade performance in multilayer dielectricity characterizes by means of numerical simulation shock wave for Gupta and Ding, has proposed exploratory decision method.Because the propagation problem of stress wave in multilayer dielectricity exists the coupling of load and medium, and the difficult point, the particularly dynamic response under impact loading for foamed material such as the more complicated boundary value condition of multiple layer combination medium self.
Application number is that 201010147708.1 patent discloses a kind of flame-retardant high-resilience foam material, it is characterized in that mixing by PPG, crosslinking agent, varies catalyst and modification MDI the polyurethane foamed material forming.Although it has resilience equally, but cannot better resist the impact of bullet.And select the anti-bullet hybrid materials of resilience, and by absorbing energy layer and the combination of built-in bounce-back layer, and reinforced bonding between layers, more can give full play to the excellent properties of material.
Application number is that 99101874.5 patent discloses a kind of good low-repulsion that has, as the low resilience urethane foam that rushes technical ability absorbing material, acoustic material and packing.But this material is more single, cannot meet the requirement for ballistic performance in military project.
Summary of the invention
For addressing the above problem, the present invention discloses the anti-bullet hybrid composite of a kind of resilience, it is characterized in that being comprised of five-layer structure, is respectively superficial layer, collision layer, absorbing energy layer, built-in bounce-back layer, resistant layer.Surface density is 60～90Kg/m2, can tackle the middle-size and small-size bore armor-piercing incendiaries such as 7.62mm, 12.7mm, 14.5mm, or with the similar shrapnel of its kinetic energy, or other middle-size and small-size bore bullets.Composite construction bullet resistant material of the present invention, each layer by binding agent strong bond, superficial layer 10 is comprised of corundum or carborundum or boron carbide element, ceramic component can be graininess, also can be tabular, that particle comprises be spherical, the cylindricality that both ends of the surface are parallel, the cylindricality that both ends of the surface are heaved, hollow cylindricality, the corundum ceramic post of preferentially selecting both ends of the surface to heave, the diameter of ceramics pole is 10～20mm; Collision layer 20 is comprised of TC4 titanium alloy or fibrous composite, for small-bore armor-piercing incendiary, preferentially selects carbon fibre composite or Kafra fiber composite, for medium caliber armor-piercing incendiary, preferentially selects TC4 titanium alloy; Absorbing energy layer 30 is comprised of through-hole foamed metal aluminium or silicon rubber foam plate, preferentially selects through-hole foamed metal aluminium; Built-in bounce-back layer 40 is comprised of silicon rubber or natural rubber, infiltrates absorbing energy layer through-hole foam base section, preferentially selects silicon rubber; Resistant layer 50 is comprised of TC4 titanium alloy or fibrous composite, for small-bore armor-piercing incendiary or surface density, require lower composite construction bullet resistant material, preferentially select carbon fiber or Kafra fiber composite, for medium caliber armor-piercing incendiary, preferentially select TC4 titanium alloy.The thickness of each layer is along with the bore of armor-piercing incendiary is different and each variant, superficial layer 10 thickness are 10～20mm, and collision layer 20 thickness are 2～5mm, and absorbing energy layer 30 thickness are 10～30mm, built-in bounce-back layer 40 thickness are 5～20mm, and resistant layer 50 thickness are 1～4mm.
Foamed aluminium has excellent physical property, chemical property and mechanical property and recuperability.It has high-damping shock stability and impact energy absorb rate, and the 5-10 that damping capacity is metallic aluminium doubly, when 50% modification occurs the foamed aluminium that porosity is 84%, can absorb energy more than 2.5MJ/M3C.And material large rubber-like viscoplasticity is injected into after foamed aluminium, the effect of its energy-absorbing bounce-back is more remarkable.
The invention has the advantages that: (1) high-strength light, can resist the impact of large load; (2) porous foam structure plate has the performances such as energy absorption, lightweight, shock-resistant, recuperability; (3) each material property supplements mutually, has avoided the shortcoming such as fragility of homogenous material, thereby has jointly brought into play its effect.
