Problems solved by technology
[0009] The purpose of the present invention is to solve the above-mentioned existing bulletproof helmets for the defense of projectiles and shrapnel, which are realized by improving the strength of the helmet itself, designing energy-absorbing structures, etc., which cannot meet the needs of individual soldiers' protection, and lack the bionic helmet inner lining. , the impact angle of projectiles and shrapnel on the helmet is large, the helmet has low anti-penetration ability, poor impact energy absorption, and low buffer protection ability for personnel's cervical spine, brain and other organs, and a bionic energy-absorbing buffer bulletproof helmet is provided. lining

Embodiment Construction
[0033] see figure 1 , figure 2 and image 3 As shown, this embodiment is composed of an inner lining composed of an anti-penetration scale structure 1, a composite energy-absorbing sponge 2 and a multi-layer staggered Kevlar fiber bushing 3, and the composite energy-absorbing sponge 2 is fixedly arranged on a multi-layer staggered On the type Kevlar fiber bushing 3, the anti-penetration scale structure 1 imitating the clam shell is fixedly arranged on the composite energy-absorbing sponge body 2;
[0034] The composition and mass percentage of the anti-penetration scale structure 1 are as follows:
[0035] Epoxy resin 55%-75%, xylene 5%-20%, boron trifluoride 5%-20%, nano-silicon carbide whiskers 0.5%-1.5%, nano-TiO2 particles 0.5%-1.5%, nano-TiB particles 0.5%-1.5%, short carbon fiber 2.5%-6%, nano-Al2O3 particles 0.5%-1.5%;
[0036]The preparation method of the anti-penetration scale structure is as follows:
[0037] Mix nano-silicon carbide whiskers, nano-TiO2 particl...

The invention discloses a bionic energy absorbing and cushioning lining for a ballistic helmet. The bionic energy absorbing and cushioning lining consists of an anti-penetration scaly structure, a compound energy absorption sponge body and a multi-layer interlaced Kevlar fiber bushing, wherein the compound energy absorption sponge body is fixedly arranged on the multi-layer interlaced Kevlar fiber bushing; and the clam shell imitated anti-penetration scaly structure is fixedly arranged on the compound energy absorption sponge body. The anti-penetration scaly structure can effectively reduce the impact angle of a bullet and shrapnel to the helmet, reduces the structural weight and relieves the load of combatants; the compound energy absorption sponge body can play a cushioning protection role on such organs as cervical vertebrae and brains of the combatants; and the multi-layer interlaced Kevlar fiber bushing is formed by pasting multiple layers of Kevlar fiber cloth layer by layer at a certain angle, therefore has favorable strength in all directions, and is further improved in the anti-penetration capability.
Description
technical field [0001] The invention relates to the technical field of helmets, in particular to a bionic energy-absorbing buffer bulletproof helmet lining. Background technique [0002] In modern warfare, the lethality of offensive weapons is increasing, and the lethality to combatants is getting higher and higher. The self-protection of individual soldiers has become an important means and method to improve the survival rate of combatants, and the protection of the head is of great importance to the combatants. Guaranteeing the life safety of combatants plays an extremely important role. At present, bulletproof helmets are designed with new structures, and relevant patent reports at home and abroad are as follows: [0003] 1. Chinese patent, the announcement number is CN204649082U, the announcement date is 2015-09-16, the application number is CN201520122617.0, and the invention name is "bulletproof helmet and its mold set", which discloses a bulletproof helmet and its mol...
