After the cold war is finished, the traditional large-scale and high-strength battlefield attack and defense combat is relatively reduced. But the persistent small-scale battle cannot be avoided due to regional disputes, counter-terrorism and requirement. The fact that soldiers are increasingly at higher risk of being struck by infantry small arms projectiles and fragments due to long time duration and the danger is sometimes even higher than that of large-scale battlefield military operations is undoubtedly explained in the united states that after the primary military operations of irak, the number of casualties caused by the soldiers being struck is much higher than that during the primary war operations. In order to protect the life safety of soldiers, maintain the soldier strength and the fighting ability of troops and ensure the action success, the preparation of multifunctional individual-soldier ballistic protection equipment is particularly important.
For individual bulletproof garments, the capabilities of bulletproof, fragment prevention, puncture prevention, fire prevention and impact resistance are required, non-penetrating damage caused by large deformation of the bulletproof garments is also required to be avoided, and the guarantee of flexibility is also an important factor for improving the mobility of soldiers. The existing individual protective equipment can be mainly divided into three types: hard protective equipment, soft protective equipment and compound protective equipment. The hard protective equipment mainly uses special steel, aluminum alloy and other metals as bulletproof materials, although the protective equipment can effectively resist bullets, the protective equipment is heavy and uncomfortable to wear, and hard ceramics are adopted, so that a large amount of fragments can be generated, and secondary damage can be generated; the soft protective equipment is light and concealed, has good fitness, is easy to generate non-penetrating damage after being hit by a bullet and has large deformation, and cannot play an effective protective role in the puncture of the cutter. The third kind of composite protective equipment is the direction of current each country's main development, utilizes the big stereoplasm steel sheet of deformation modulus, pottery and soft, the better combination of fabric of comfort level promptly, but present composite protective equipment is mostly the monoblock shellproof picture peg, is not conform to human body design, is not convenient for action and battle promptly, can't use four limbs and neck protection moreover.
