The central compartment of degree is that bullet surface layer and the back of the body play surface layer, bullet surface layer carbon fiber volume content and contains with back of the body bullet surface layer carbon fiber volume
The ratio of amount is less than 1.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, and the high-performance is tough
Property resin matrix be high-toughness epoxy resin, thermoplasticity or heat-curable urethane, TPO plastics, thermoplastic poly esters
Any one in plastics or two or more combinations.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, the high-performance pottery
Porcelain comprising oxide, carbide ceramics and nitride special cermacis and with one or both of the composite ceramics of carbon fiber and with
On compound.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, and the multicomponent is answered
Mould assembly high-performance fiber with high-performance toughened resin matrix is formed by hot pressing global formation, and temperature range is 80 ~ 400 DEG C,
Pressure limit is 0.1 ~ 3.0MPa, and hot pressing time is 20 ~ 300min.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, the high-performance pottery
Porcelain with bullet resistant material body is formed by high-performance toughness adhesive quick-binding, and the adhesion process is individually shaping pottery
Bonded again after porcelain and bullet resistant material body.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, bullet resistant material body
Back of the body bullet face conformed to the convex carbon fibre laminates of the anti-back of the body.
The present invention compared with prior art, material sheet is played by main enhancing of the compound high-performance special fiber of multicomponent
Body, using the material, on the premise of smaller surface density is ensured, can both realize preferable anti-penetration performance, can reduce again
What the larger convex amount of the back of the body was caused injures to human body non-through.Overcome traditional metal materials heaviness and one-component ballistic composite
The universal relatively low shortcoming of ballistic performance.
Embodiment
Concrete technical scheme of the invention described further below, in order to which those skilled in the art is further understood that
The present invention, without constituting the limitation to its right.
A kind of preparation method of high performance ballistic composites, using the compound high-performance special fiber of multicomponent as main increasing
Qiang Ti, using high-performance toughened resin matrix as adhesive, bullet resistant material body is formed by high temperature hot pressing global formation.
The compound high-performance fiber of described multicomponent is that carbon fiber is composited with high-performance fiber alternative stacked.
Wherein high-performance fiber is in high-tenacity polyethylene fibre, aramid fiber, polyparaphenylene's Benzo-dioxazole, glass fibre
Any one.Can also be it is above-mentioned it is any two or more.
Its example 1 is that carbon fiber is combined with high-tenacity polyethylene fibre alternative stacked;
Its example 2 is that carbon fiber is combined with aramid fiber alternative stacked;
Its example 3 is that carbon fiber is combined with polyparaphenylene's Benzo-dioxazole alternative stacked;
Its example 4 is that carbon fiber is combined with glass fibre alternative stacked;
Its example 5 is compound for one layer of one floor height strong polyethylene fibres of carbon fiber, one layer of such alternative stacked of aramid fiber;
Its example 6 is that one layer of such alternative stacked of carbon fiber one layer of one floor height strong polyethylene fibres, one layer of carbon fiber aramid fiber is answered
Close;
Its example 7 is one layer of carbon fiber one layer of one floor height strong polyethylene fibres, one layer of carbon fiber, one layer of aramid fiber strata of carbon fiber one
It is compound to the such alternative stacked of penylene Benzo-dioxazole;Etc..
It is 1 ~ 30% that carbon fiber, which accounts for cumulative volume ratio,.
Bullet resistant material body is by bullet surface layer of the central compartment of thickness and the back of the body plays surface layer, bullet surface layer carbon fiber volume and contains
The ratio that amount plays surface layer carbon fiber volume content with the back of the body is less than 1.
The high-performance toughened resin matrix is high-toughness epoxy resin, thermoplasticity or heat-curable urethane, thermoplastic poly
Any one in olefin plastics, thermoplastic poly esters plastics or two or more combinations.
The anti-convex carbon fibre laminates of the back of the body can have individually been conformed in the back of the body bullet face of bullet resistant material body in addition.Reduce to greatest extent
Convex amount is carried on the back, personal safety is protected.
The compound high-performance fiber of multicomponent and high-performance toughened resin matrix are formed by hot pressing global formation,
Temperature range is 80 ~ 400 DEG C, and pressure limit is 0.1 ~ 3.0MPa, and hot pressing time is 20 ~ 300min.
Bullet resistant material body bullet face be stained with high-performance ceramic reach shellproof class 5 level and more than, and then fully send out
The shellproof advantage of Material cladding is waved.
The high-performance ceramic includes oxide, carbide ceramics and nitride special cermacis and the composite ceramic with carbon fiber
The compound of one or both of porcelain and the above.
The high-performance ceramic with bullet resistant material body is formed by high-performance toughness adhesive quick-binding, the bonding
Process is individually bonded after forming ceramic and bullet resistant material body again.
