Pehea e koho ai i ka papa pōkā

Hoʻohana ʻia ka hoʻohana ʻana i nā papa seramika i ka makahiki 1918, ma hope o ka pau ʻana o ke Kaua Honua I, i ka manawa i ʻike ai ʻo Colonel Newell Monroe Hopkins e hoʻomaikaʻi nui ʻia ka pale ʻana o ka pale kila me ka glaze seramika.

ʻOiai ua ʻike mua ʻia nā waiwai o nā mea seramika, ʻaʻole i liʻuliʻu ma mua o ka hoʻohana ʻia ʻana no ka hana kaua.

ʻO nā ʻāina mua i hoʻohana nui i nā mea kaua ceramic ʻo ia ka Former Soviet Union, a ua hoʻohana nui ka pūʻali koa US iā ia i ka wā o ke Kaua Vietnam, akā ua puka wale ka pale kila ma ke ʻano he mea pale pilikino i nā makahiki i hala ma muli o ke kumu kūʻai mua a me nā pilikia ʻenehana.

ʻO kaʻoiaʻiʻo, ua hoʻohana ʻia ka alumina ceramic i loko o ka pale kino ma UK i ka makahiki 1980, a ua hoʻokumu ka pūʻali koa US i ka SAPI "plug-in board" mua loa i nā makahiki 1990, ʻo ia kahi mea pale pale kipi i kēlā manawa.ʻO kāna kūlana palekana NIJIII hiki ke hoʻopaʻa i ka hapa nui o nā pōkā e hiki ke hoʻoweliweli i ka infantry, akā ʻaʻole ʻoluʻolu ka pūʻali koa US i kēia.Ua hānau ʻia ʻo ESAPI.

 

ESAPI

I kēlā manawa, ʻaʻole ʻoi aku ka nui o ka pale ʻana o ESAPI, a ʻo ka pae o ka NIJIV o ka pale i kū i waho a hoʻopakele i nā ola o nā koa lehulehu.Pehea ka hana ʻana ʻaʻole paha i manaʻo nui ʻia.

No ka hoʻomaopopo ʻana i ka hana ʻana o ESAPI, pono mākou e hoʻomaopopo mua i kona ʻano.ʻO ka hapa nui o nā mea kaua ceramic composite he pahuhopu ceramic structural + metal/non-metal back target, a hoʻohana pū ka pūʻali koa US ESAPI i kēia ʻano.

Ma kahi o ka hoʻohana ʻana i ka silicon carbide ceramic e hana ana a he "economical", ua hoʻohana ka US Army i ka ʻoi aku ka pipiʻi o ka boron carbide ceramic no ESAPI.Ma ka mokulele hope, ua hoʻohana ka pūʻali koa US i ka UHMW-PE, a he pipiʻi loa ia i kēlā manawa.Ua ʻoi aku ke kumukūʻai o ka UHMW-PE mua ma mua o ka carbide BORON.

'Ōlelo Aʻo: ma muli o ka ʻokoʻa ʻokoʻa a me ke kaʻina hana, hiki ke hoʻohana ʻia ke kevlar ma ke ʻano he pā hope e ka pūʻali koa US.

 

ʻO nā ʻano seramika pale pōkā:

ʻO nā ceramics bulletproof, i ʻike ʻia he structural ceramics, he paʻakikī kiʻekiʻe, nā hiʻohiʻona modulus kiʻekiʻe, hoʻohana pinepine ʻia no ka abrasion metala, e like me ka wili ʻana i nā pōpō seramika, ke poʻo mea hana wili seramika…….I loko o nā mea kaua i hui pū ʻia, hoʻokani pinepine nā ceramics i ke kuleana o ka "warhead luku".Nui nā ʻano seramika i loko o ka pale kino, ʻo ka mea maʻamau ka alumina ceramics (AI²O³), silicon carbide ceramics (SiC), boron carbide ceramics (B4C).

ʻO kā lākou mau hiʻohiʻona:

ʻO ka alumina keramika ka mea kiʻekiʻe loa, akā he haʻahaʻa ka paʻakikī, ʻoi aku ka haʻahaʻa o ka paepae hana, ʻoi aku ka liʻiliʻi o ke kumukūʻai.ʻOkoʻa ka maʻemaʻe o ka ʻoihana i -85/90/95/99 alumina ceramics, ʻoi aku ka maʻemaʻe o kona lepili, ʻoi aku ka paʻakikī a me ke kumukūʻai.

He haʻahaʻa ka nui o ka carbide silikoni, he ʻano haʻahaʻa ka paʻakikī like, no ke ʻano o nā seramika maikaʻi loa, no laila e hoʻohana ka hapa nui o nā mea hoʻokomo kino kino i ka silicon carbide ceramics.

ʻO Boron carbide ceramics i kēia mau ʻano seramika i ka haʻahaʻa haʻahaʻa, ka ikaika kiʻekiʻe loa, a ʻo kāna ʻenehana hana ʻana he mea kiʻekiʻe loa nā koi, kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe puʻe sintering, no laila ʻo kāna kumukūʻai ʻo ia hoʻi nā seramika nui loa.

ʻO ka lawe ʻana i ka papa NIJ ⅲ ma ke ʻano he laʻana, ʻoiai ʻo ke kaumaha o ka alumina ceramic insert plate he 200g ~ 300g ma mua o ka silicon carbide ceramic insert plate, a me 400g ~ 500g ma mua o ka boron carbide ceramic insert plate.Akā ʻo ke kumukūʻai ʻo 1/2 o ka silicon carbide ceramic insert plate a me ka 1/6 o ka boron carbide ceramic insert plate, no laila ʻo ka alumina ceramic insert plate ka mea kiʻekiʻe loa o ka hana a no ka mākeke alakaʻi huahana.

Hoʻohālikelike ʻia me ka pā pōkā metala, ʻo ka composite/ceramic bulletproof plate ka loaʻa ʻole o ka pōmaikaʻi!

ʻO ka mea mua, paʻi ka pale kila i ka pale kila homogeneous e ka projectile.Ma kahi kokoke i ka wikiwiki o ke komo ʻana, ʻo ke ʻano hemahema o ka pā i hoʻopaʻa ʻia ʻo ia ka nui o nā lua pele a me nā slugs shear, a ʻo ka hoʻohana ʻana i ka ikehu kinetic e hilinaʻi nui ʻia i ka hana shear i kumu ʻia e ka deformation plastic a me nā slugs.

ʻOi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka ikehu o ka mea kila hoʻohuihui mea kaua ma mua o ka mea pale metala homogeneous.

 

Hoʻokaʻawale ʻia ka hopena o ka pahu ceramic i ʻelima mau kaʻina

1: ua haki ʻia ka hale pōkā i loko o nā ʻāpana liʻiliʻi, a ʻo ka ʻoki ʻana i ke poʻo kaua e hoʻonui i ka wahi hana i manaʻo ʻia, i mea e hoʻopuehu ai i ka ukana ma ka pā seramika.

2: ʻike ʻia nā māwae ma ka ʻili o nā seramika i ka ʻāpana hopena, a hoʻonui i waho mai ka ʻāpana hopena.

3: ʻO ke kahua ikaika me ka ʻaoʻao hopena o ka nalu kaomi i mua o ka loko o ka ceramic, no laila ua haki ka ceramic, ka pauda i hana ʻia mai ka hopena a puni ka projectile e lele ana i waho.

4: nā māwae ma ke kua o ka ceramic, ma waho aʻe o kekahi mau māwae radial, māhele ʻia nā māwae i loko o ka cone, e hiki mai ana ka poino i loko o ka cone.

5: ka ceramic i loko o ka cone ua wawahi i mau apana ma lalo o paʻakikī pilikia kūlana, i ka projectile hopena ceramic ili, ka hapa nui o ka ikehu kinetic ua pau i ka luku ana o ka cone ka poepoe lalo wahi, kona anawaena pili i ka mechanical waiwai a me geometric ana. o ka projectile a me ka mea seramika.

ʻO ka mea i luna nei wale nō nā hiʻohiʻona pane o ka mea kaua seramika ma nā projectiles wikiwiki haʻahaʻa.ʻO ia, nā hiʻohiʻona pane o ka wikiwiki projectile ≤V50.Ke ʻoi aku ka kiʻekiʻe o ka wikiwiki o ka projectile ma mua o V50, hoʻopau ka projectile a me ka ceramic i kekahi i kekahi, e hana ana i kahi mescall crush zone kahi e ʻike ʻia ai nā mea kaua a me ke kino projectile e like me ka wai.

He paʻakikī loa ka hopena i loaʻa i ka mokulele hope, a ʻo ke kaʻina hana he ʻekolu-dimensional ma ke ʻano, me nā pilina ma waena o nā papa hoʻokahi a ma waena o kēia mau papa fiber pili.

Ma nā huaʻōlelo maʻalahi, ʻo ka nalu koʻikoʻi mai ka nalu lole a hiki i ka matrix resin a laila i ka papa pili, ke ʻano o ka nalu ʻeha i ka intersection fiber, ka hopena i ka hoʻopuehu ʻana o ka ikehu hopena, ka hoʻolaha ʻana o ka nalu i ka resin matrix, ka hoʻokaʻawale ʻana o ka. papa lole a me ka neʻe ʻana o ka ʻili lole e hoʻonui i ka hiki o ka composite e komo i ka ikehu kinetic.ʻO ka neʻe ʻana ma muli o ka hele ʻana a me ka hoʻolaha ʻana a me ka hoʻokaʻawale ʻana o nā papa lole hoʻokahi hiki ke hoʻopaʻa i ka nui o ka ikehu hopena.

No ka hoʻokolohua hoʻokolohua hoʻokolohua kūʻē kūʻē o nā mea kaua ceramic composite, hoʻohana ʻia ka hoʻokolohua simulation i loko o ka hale hana, ʻo ia hoʻi, hoʻohana ʻia ka pū kinoea e hoʻokō i ka hoʻokolohua komo.

 

No ke aha i loaʻa ai iā Linry Armor ka uku kumukūʻai ma ke ʻano he mea hana i nā mea hoʻokomo pōkā i nā makahiki i hala?ʻElua kumu nui:

(1) Ma muli o nā pono ʻenekinia, nui ke koi ʻana i nā ceramics structural, no laila he haʻahaʻa loa ke kumu kūʻai o nā ceramics structural.

(2) Ma keʻano he mea hana i nā mea waiwai a me nā huahana i hoʻopauʻia i loko o kā mākou mau hale hana pono'ī, i hiki iā mākou ke hāʻawi i nā huahana maikaʻi loa a me nā kumukūʻai maikaʻi loa no nā hale kūʻai pōkā a me nā kānaka.
