Feem ntau ntawm cov kaus mom hlau yog tsim los ntawm Aramid Fiber (Kevlar) thiab UHWM-PE.
Kevlar, yog tias koj xav tias yog hom fiber ntau. Nws tsis yog ib feem ntawm cov yas.
Feem ntau ntawm cov kaus mom hlau muaj cov khaubncaws sab nraud povtseg ntawm Kevlar uas txuas nrog cov resin txhawm rau muab daim ntawv rau cov kaus mom hlau thiab tiv thaiv deformation vim yog cov phiaj xwm.
Lub kaus mom hlau tsis muaj phom yog tsim los ntawm ib qho tseem ceeb "Hard"
Nws yog cov resin uas muab 'hardness' ntawm headgear, thiab tsis yog Kevlar nws tus kheej. Kevlar tsis muaj dab tsi ntau tshaj li cov ntaub uas tiv thaiv cov kua muag thiab nws cov txheej txheem txheej tsim cov shear- cov khoom tiv thaiv kom tsis txhob muaj cov mos txwv los ntawm cov xov ntawm koj lub taub hau.
Txawm li cas los xij, cov ntaub ntawv qib siab dua pib hloov Kevlar los ua cov kaus mom hlau. Dab tsi yog Dyneema lossis Spectra yog txhua "Ultra Ultra High Molecular Nyhav Polyethylene (UHMW-PE)". Qhov no yog tib yam khoom siv los ua cov hlua nce toj.
Lawv muaj zog dua nyob rau hauv cov nqe lus ntawm shear thiab kua muag tsis kam tshaj Kevlar thiab tau tuav tawm tsam 5.56mm rounds. Rau kev ncua ntev cov khoom siv tuaj yeem tiv taus 7.62 NATO raws li ib tus phooj ywg ntawm kuv tau sim ntawm qhov ntau, txawm tias nws tsis ntsuas rau cov calibers no. Feem ntau ntawm cov kaus mom hlau no tau muab cais IIIA rau qhov tsawg kawg nkaus, txawm li cas los xij, cov tub rog tau sau tseg tias lawv cov kaus mom hlau tau tiv thaiv lawv los ntawm kev tua hluav taws.
Peb lub tuam txhab muaj cov kaus mom hlau zoo li hauv qab no:

Cov kaus mom hlau zoo li cov uas tsim los ntawm lub tuam txhab Choweyarmor yog cov piv txwv ntawm cov ntaub ntawv tshiab tau ua haujlwm hauv nws cov khoom.
