It should be noted that the ballistic structure that the embodiment of the present invention provides, can be flexible ballistic structure, also can be rigid armor structure.
When ballistic structure is flexible ballistic-resistant structure time, it can along with the application of reality, cover the surface needing shellproof people, object etc., its shape can make change according to the shape of people or object, such as, with direct flak jackets flexible ballistic-resistant structure being manufactured laminating human body radian.And time if ballistic structure is rigid armor structure, ballistic structure can be made into bulletproof flashboards or armour, multiple pocket being used for placing bulletproof flashboards such as can be set on flak jackets, directly bulletproof flashboards is inserted in these pockets, protection is accomplished to the key protection position of human body.
Shown in Fig. 1, Fig. 2 and Fig. 3, on the basis of above-described embodiment, the embodiment of the present invention also provides a kind of concrete structure of protective layer 103:
Described protective layer 103 comprises: inner protective layer 104 and/or external protection 105;
Described inner protective layer 104 and the side close adhesion of described suction ripple layer 102 away from described burster course 101;

Particularly, the concrete shape of ballistic structure can carry out concrete setting according to the Production requirement of reality.Such as, if ballistic structure is used in the plan-position of bullet-proof car, then ballistic structure is made into flat board, and now, ballistic structure should be rigid armor structure, such as armour; When being used on flak jackets by ballistic structure, human body itself has certain radian, therefore ballistic structure can be made the arc along human body radian; Same, according to the real needs of human body, bullet-proof car, ballistic structure can also be made into sketch plate etc.
If rigid armor structure, ballistic structure can be formed the armour of arc, if flexible ballistic-resistant structure, can according to the pattern being similar to vest, by flexible ballistic-resistant structural tailoring, be spliced into abnormity along body configuration.In addition, it should be noted that the application of rigid armor structure and flexible ballistic-resistant structure has difference, actual selective gist can be carried out according to the application scenarios of reality.Wherein, different application has respective benefit, such as, if the armour of rigidity is applied on flak jackets, armour can be made bulletproof flashboards, if certain sheet bulletproof flashboards is hit rear damage, directly can change for this bulletproof flashboards, the normal use of other bulletproof flashboards can not be affected.And if use the flak jackets of flexible ballistic-resistant structure fabrication, more can fit with human body, less on the impact of action.
In addition, shown in Figure 4, also provide a kind of protective gear in another embodiment of the present invention, comprise carrier 10, and be arranged on the ballistic structure 20 as described in above-described embodiment on described carrier 10.
This protective gear, due to ballistic structure 20, include the burster course, suction ripple layer and the protective layer that superpose bonding successively, wherein burster course is positioned at the outermost layer of ballistic structure, and it mainly plays shellproof effect.When bullet impact ballistic structure, can directly contact with burster course, burster course absorbs shock wave and stops penetrating of bullet; Shock wave is after absorbing through burster course, understand some shock wave through burster course, pass to the suction ripple layer after being positioned at burster course, inhale ripple layer to the incidence wave produced during bullet impact ballistic structure and reach bi-material interface time the back wave that produces rise simultaneously and inhale ripple and iris action; The remaining shock wave through inhaling ripple layer be then positioned at inhale protective layer after ripple layer absorb.In this process, shock wave is not only have burster course consumed, but by absorbing layer by layer, successively decreasing gradually, being finally consumed.Thus ballistic structure provided by the present invention, when being subject to bullet impact, the impact of shock wave to burster course can be reduced, reducing ballistic structure interlaminar separation, being penetrated, cave in the phenomenon such as excessive, thus, protective gear provided by the present invention possesses better protective characteristic.
