Description
Technical field
The utility model provides a kind of fibre-reinforced metal/ceramic laminated composite material prevention plate, belongs to the armour plate technical field.
Background technology
Existing protection armour plate mainly contains three kinds, first kind of protection armour plate for making by high strength alloy steel, and this protection armour plate good toughness, but hardness is low.Second kind of protection armour plate for making by the high tenacity pottery, this protection armour plate density is little, the hardness height, but shock resistance is poor, and broken easily in daily use, lose protection effect.The third is the compound protection armour plate of metal/ceramic glue bonding, the intensity of metallic plate and ceramic wafer combination is low, under the strike effect of high speed bullet, the effect that absorbs the bullet energy is undesirable, the same with second kind of protection armour plate of making by the high tenacity pottery, lack anti-Secondary Strike Capacity, and glue loses cementitiousness easily in the environment of solar radiation and humidity.Up-to-date invention disclosed patent application, application number is: 200410098948.1, Chinese patent publication number CN1623770, open day is that the name of innovation and creation on June 8 in 2005 is called metal/ceramic laminated composite material prevention plate, propose a kind of protective plate of the metal/ceramic laminated composite construction of making by multiple metal and ceramic welding, had the toughness of metal material and the hardness of ceramic material concurrently.The utility model improves on the basis of foregoing invention and forms, connecting technology in metal/ceramic laminated composite material inside by special type enters high strength fibres such as quartz fibre and carbon fiber are compound, utilize the very high tensile strength of high-intensity fiber, metal/ceramic laminated composite material is further strengthened, further improve the ability of its anti-high speed bullet penetration.
Summary of the invention
The purpose of this utility model provides a kind of fibre-reinforced metal/ceramic laminated composite material prevention plate, improves bulletproof effect and dependability, alleviates protective plate weight, improves the anti-two-hit performance of composite protective plate.
Protective plate described in the utility model has at least one metal level/fibrage/ceramic layer sandwich structure, described sandwich structure is under 600 ℃～1650 ℃ temperature, connects technology, powder sintering process or active metal brazing technology by the activity casting metal level, fibrage and ceramic layer are welded together.
Wherein, the metal level of described protective plate be aluminium, admire, sheet material that iron, nickel and alloy thereof are made; The fibrage of described protective plate, its fiber are quartz fibre or carbon fiber.Described protective plate ceramic layer is the sheet material that aluminium oxide, aluminium nitride, silicon nitride, carborundum or boron carbide are made.
Wherein, described active casting connects technology and is: under 600 ℃～1650 ℃ high temperature, reduce the surface tension of metal bath by physics or chemical method, make it can be at ceramic surface moistening and solidify, thereby fiber, metal and ceramic welding are in the same place.The physical method that described physical method is for example removed the oxide-film of molten surface reduces molten surface tension force and realizes moistening to ceramic material, described chemical method be in liquation, add zirconium, titanium etc. can be at high temperature can and pottery the Activity of Chemical Reaction metallic element takes place reduces molten surface tension force, finally realize metal and ceramic being connected.
Described powder sintering process is: with sintered powder material evenly brushing will in conjunction with metal level, fibrage and ceramic layer surface, and place them in together, in baking oven, organic solvent is dried earlier, be placed in the vacuum electric furnace then, be warmed up to 1200 ℃～1600 ℃, be incubated 45～120 minutes,, can obtain in conjunction with good fibreglass-reinforced metal/ceramic laminar composite material protective board with the stove cooling.
Described active metal brazing technology is: with the active metal brazing material evenly brushing will in conjunction with metal level, fibrage and ceramic layer surface, and place them in together, in baking oven, organic solvent is dried earlier, be placed in the vacuum electric furnace then, be warmed up to 600 ℃～1650 ℃ at a slow speed, be incubated 10～15 minutes,, can obtain in conjunction with good fibreglass-reinforced metal/ceramic laminar composite material protective board with the stove cooling.
Advantage of the present utility model and effect are: it has metal material, fibrous material and ceramic material characteristics separately concurrently, hardness height not only, lear energy is good, and good toughness, in light weight, have and protect the ability that the high speed bullet hits preferably, can be widely used in flak jackets, armored vehicle and need on the aircraft of armor facing.
The thermal coefficient of expansion of metal material and ceramic material is different, both at high temperature connect technology by the activity casting and active metal brazing technology welds together, during cool to room temperature, there is internal stress in metal/ceramic laminated composite material (being called for short metal makes pottery) inside, because the thermal coefficient of expansion of metal is higher than pottery, the effect of pottery compression chord, the characteristics of ceramic material are that compressive property is far away because its stretch-proof performance, this stress also can cause the atomic lattice distortion of metal material, effectively improve hardness of metal materials, the existence of metal pottery internal stress is highly beneficial for the ability that improves its anti-high speed bullet impact.High strength fibre such as quartz fibre and carbon fiber has very high tensile strength, can absorb more energy during the high strength fibre fracture, the utility model utilizes high-intensity fiber that metal/ceramic laminated composite material is strengthened, can utilize the high strength of fiber further to improve the tear resistance of protective plate, under protective plate weight increase situation seldom, effectively improve its bulletproof effect.
Different with common ceramic protective plate is, protective plate described in the utility model shows the performance of metalloid plate under high speed bullet strike effect, have anti-secondary and impact ability, under the high speed bullet hits, the ceramic material protective plate is all beaten to such an extent that pulverize usually, and protective plate described in the utility model under the high speed bullet hits except the part of being hit by bullet is destroyed, other partly are kept perfectly, and still have protective action.
