Description
Technical field
Strengthen light composite material, more particularly to a kind of ultra-high molecular weight polyethylene three the present invention relates to a kind of three dimensional fabric
Dimensional fabric enhancing light composite material and preparation method thereof.
Background technology
With developing rapidly for modern science and technology, attack weapon system achieves significant progress, forces tank vehicle
Metal protection layer is more and more thicker, and its combat weight is increasing, has a strong impact on the mobility and quick-reaction capability of operation.Pass
The metal material of system is increasingly difficult to meet the comprehensive war skill index request of new type tank vehicle.Mitigate armored vehicle itself weight
Amount, raising tank vehicle barrier propterty, enhancing battlefield penetration ability, in the urgent need to application high-strength light, with good elastoresistance
Traditional metal material can be substituted with the light material of excellent fatigue performance.Lightweight bulletproof material is not only lightweight, simultaneously
The performance requirement such as anti-bullet, stealthy, damping noise reduction, three proofings, fire-retardant must also be met.Modern Intelligence Technology, offensive weapon guidance skill
The development of art, nuclear radiation etc. proposes higher requirement to armored hull protection.Traditional metal material is used alone can not
Meet the demand of each side.With world's new and high technology, fiber synthesis and the development of spinning technique, high-performance fiber has been obtained not
Disconnected development innovation, has had been introduced into the stage of a high speed development at present.Application fine dew of the fibrous material in ballistic area
The brilliance has played more and more important effect.Especially the high performance fibers such as UHMWPE fibers, aromatic polyamide fibre are anti-
Application in terms of bullet equipment has obtained the attention of various countries' military power.High-performance fiber has higher intensity, higher modulus
It is less than metal material with the density of appropriate elongation at break, and fiber.Therefore, the bullet resistant material that high performance fibre material is made
Light weight, pliability are good, protection effect is good.In recent years, various countries have developed various soft, soft or hard multiple using high performance fibre material
Box-like flak jackets and bulletproof halmet.Fibre reinforced composites have high specific strength, specific modulus height, performance designability strong, electric
Performance is good and the features such as good fatigue durability, and it is combined with traditional bullet resistant material-ceramics, steel plate etc. one by one
The lightweight armor materials of structure/function integration, can reduce armored vehicle combat weight up to more than 30%, realize mobility
With the unification of protective capacities, the survival ability of vehicle is improved.
At present, the high-performance fiber applied to ballistic area mainly have carbon fiber, aramid fiber, heteroaromatic fiber,
UHMWPE fibers, glass fibre, since 21 century, with the development of science and technology, high-performance fiber and its enhanced multiple
Condensation material is widely used in the every field such as ship, automobile, Aero-Space, national defence weapons, and fiber-reinforced resin base is multiple
Condensation material proportion shared in national product is increasing.Being presently used for the fiber of reinforced resin based composites mainly has
Carbon fiber, aramid fiber and superhigh molecular weight polyethylene fibers, are the generally acknowledged high-performance fibers continued to develop in recent years, have
The premium properties such as high-strength, Gao Mo, shock resistance, corrosion-resistant.
The light weight of high performance composites and flexible so that these materials are into the leading of modern individuals ballistic area
Property material.In the pistol cartridge of protection lead for retractable pencil or the software ballistic composite of gubmachine gun cartridge, main high-performance fiber includes
Aramid fiber, superhigh molecular weight polyethylene fibers, pbo fiber, Carbon fibe and glass fibre etc., main form of fabric have woven
Cloth, unidirectional laminated cloth (UD cloth), biaxially through (latitude) braid etc..Compared with other fabrics, the mode of production of laminated cloth is avoided
To uninfluenced of mechanical performance index such as intensity, the modulus of damage fibers of fiber and after attack during braiding
Stress wave and energy by the outside spread speed of attack point faster.Compared to carbon fiber and aramid fiber, superhigh molecular weight polyethylene fibers
Not only there is high intensity, and its raw material is easy to get, processing is relatively easy, therefore in ballistic area, ultra-high molecular weight polyethylene is fine
The development of dimension is also more rapid.Several UHMWPE fibers of current commercialization, relative density is 0.97 g/cm3, is all high
Performance fibers Midst density is minimum, be aluminium l/3 and steel 1/8, be the 2/3 of aramid fiber, the 1/2 of carbon fiber；UHMWPE fibers are answered
Condensation material is lighter than aramid fiber composite material by 20%, lighter than carbon fibre composite by 30%.Traditional ultra-high molecular weight polyethylene is fine
Ballistic composite is tieed up more in the form of UD cloth into fibre, it is that multiple layers of high strength fiber is superimposed according to vertical mode and by heat
The sheet material of pressure.UD cloth is a kind of two-dimensional fabric, is interweaved by 2 yarn systems arranged perpendicularly according to certain rule
Form.
The utility model discloses a kind of shellproof chest plate by the Chinese patent CN204612596U announced.The shellproof chest
Plate is made up of ceramic out surface and ultra-high molecular weight polyethylene backer board.The shellproof backer board of ultra-high molecular weight polyethylene is by multilayer
Ultra-high molecular weight polyethylene belt sheet material is hot-forming, or ultra-high molecular weight polyethylene belt sheet material and superhigh molecular weight polyethylene
Alkene laminated cloth is hot-forming.Chest plate, it is characterised in that described ultra-high molecular weight polyethylene belt sheet material is single by 1-6 layers
Bar ultra-high molecular weight polyethylene band lamella is constituted, and the ultra-high molecular weight polyethylene band lamella of adjacent layer is staggered；Wherein
Described ultra-high molecular weight polyethylene band lamella is formed by two layers of ultra-high molecular weight polyethylene band orthogonal weave, and its feature exists
In described ultra-high molecular weight polyethylene belt sheet material is by 2-10 layers of ultra-high molecular weight polyethylene band lamella one direction arrangement structure
Into, and adjacent ultra-high molecular weight polyethylene band lamella and the band lamella are into vertical direction laying.What is be related in the patent is super
High molecular weight polyethylene chest plate, fiber sheet vertical arrangement, is connected with each other with resin, when by bullet, shell fragment attack, easily
Cause fiber sheet to see that connectivity is not enough, make its impact resistance not enough, so as to cause ballistic performance poor, therefore, solve this
The problem of class, is particularly important.
The content of the invention
