Abstract
The present invention provides a kind of compound armours, are related to army and police's individual and armor facing field.The armour is mainly made of carbon fiber-free weft fabric, basalt fibre laminated cloth, glass fibre laminated cloth, high-strength polyethylene fiber laminated cloth, aramid fiber laid fabric.Test of being practiced shooting proves that the armor products ballistic performance prepared using the structure is excellent, and safety margin is high, most gently can reduce 5.6% or more.
Description
Technical field:
The present invention relates to a kind of compound armours, further say, are related to a kind of applied to individual soldier's individual protection
Shellproof slab products.
Background technique:
High-performance fiber is mainly used in individual protection field, is that the following individual is anti-by the woven laminated cloth of high-performance fiber
One of the important protective gear in protector for collar domain.Currently, just because of high strength fibre laminated cloth, its smaller with specific gravity, anti-bullet ratio absorbs energy
Greatly, the advantage of resist chemical and numerous protrusions such as ageing-resistant, and just gradually master of the substitution armour plate in bullet resistant material field
Status is led, yield is also being continuously increased, and is opening up new application field.Armour has been developed in recent years novel
Composite material, main application and missile-resistant shield, shellproof chest plate backboard and composite ceramic armor backboard etc., are the following states
Border one of important protective gear such as military engineering, special force, police military supplies in the market.With military and police Protection Product
Development, international composite light quantization ballistic composite is following development trend, is more and more applied to various anti-
Protector for collar domain promotes Operational Effectiveness Rat to promote tactics and efficiency and mobility on duty.
Currently, the high-performance fiber for being applied to ballistic area is mainly aramid fiber and high-strength high-modulus polyethylene fiber.This
Two kinds of fibers have respective advantage and disadvantage, and high-strength high-modulus polyethylene fiber fusing point is lower, and only 150 DEG C, by bullet penetration
When, friction generates amount of heat and is easy to scaling loss, influences its ballistic performance；Aramid fiber fusing point is high, but high-level anti-resisting
When bullet impacts, performance is weaker.And for carbon fiber, glass fibre, basalt fibre, though the bulletproof effect of itself is poor,
But it has great advantages in terms of destroying bullet bullet and promoting its deformation, the compound shellproof material with high-performance fiber
Material has apparent lightweight advantage.
Summary of the invention:
It is an object of the invention to design a kind of new type compound armour, in order to reduce the weight of armour.
A kind of new type compound armour provided by the invention, by carbon fiber-free weft fabric, basalt fibre laminated cloth, glass
Fiber laid fabric, high-strength polyethylene fiber laminated cloth and aramid fiber laid fabric composition.
The adhesive of the various laminated cloths of the present invention is that water-based polyurethane adhesive, nano silica slurries, enclosed type are different
Cyanate ratio is 100: 5~10: 1~5.And according to carbon fiber-free weft fabric, basalt fibre laminated cloth, glass fibre without latitude
Cloth, high-strength polyethylene fiber laminated cloth and aramid fiber laid fabric laminated cloth are 0 °/90 ° by structure according to laminated cloth sequence,
It is 120~130 DEG C of hot pressing in temperature, pressure is that hot pressing forms under 5~10MPa.
Test prove, compound armor products of the invention, product ballistic performance is excellent, and target sheet weight obviously compared with
Gently.Test of being practiced shooting proves that the armor products prepared using the structure, safety margin is high, and weight is lighter, can significantly improve work
The security reliability of war personnel, while the Operational Effectiveness Rat of combatant is improved, mitigate the load of personnel.
The ballistic performance test used in the embodiment of the present invention, according to Ministry of Public Security GA 141-2010, " police flak jackets is tested
Standard " it carries out, it is intended to test uses the bulletproof performance of ballistic resistant products of the invention.
