Rigid lossis composite lub cev armor (ceramic inserts + high-kev ua tau zoo fibers) muaj kev tiv thaiv zoo tshaj plaws, tshwj xeeb tshaj yog tiv thaiv siab - rab phom ntev rounds thiab armor- tho rounds, ua rau nws txoj kev xaiv tseem ceeb rau kev ua tub rog thiab tub ceev xwm.
Hom lub cev armor no sib xyaw ua ke ob lub tswv yim ntawm "cov ntaub ntawv nyuaj tawg cov mos txwv" thiab "cov ntaub ntawv mos absorbing residual zog," ua tiav qib kev tiv thaiv mus txog NIJ IV, muaj peev xwm tiv taus 7.62mm armor-txoj kev sib tw, deb tshaj qhov txwv siab tshaj ntawm Qib III A rau cov khoom siv lub cev mos mos nkaus xwb. Nws cov qauv tseem ceeb feem ntau suav nrog pem hauv ntej thiab nram qab ceramic inserts (xws li boron carbide los yog silicon carbide) thiab cov phaj nraub qaum ntawm ultra- siab molecular hnyav polyethylene (UHMWPE) los yog Kevlar fiber, ua tiav kev tiv thaiv kev sib koom ua ke ntawm "tawv tawv, muag muag."
Hauv qhov sib piv:
Cov khaub ncaws mos ntawm lub cev: Ua los ntawm ntau txheej Kevlar lossis UHMWPE tsis yog- ntaub npuag, nws yog qhov hnyav thiab hloov tau yooj yim, tsim nyog rau kev zais txhua hnub, tab sis tsuas yog tiv thaiv rab yaj phom puag ncig thiab tawg, thiab tsis tuaj yeem tiv thaiv phom phom.
Cov kaus mom hlau tiv thaiv lub tsho, thaum muaj zog, hnyav, tsis muaj qhov hloov pauv, thiab ua rau muaj kev cuam tshuam rau lwm yam blunt quab yuam; lawv tau raug hloov loj los ntawm cov vests ceramic.
Cov khoom siv tshiab cov tsho tiv thaiv mos txwv, xws li cov tsho tiv thaiv ua kua (shear- cov kua dej tuab) thiab nano- cov tsho tiv thaiv cov mos txwv, tseem nyob rau hauv kev sim lossis me me - nplai daim ntawv thov theem thiab tseem tsis tau siv dav.
Tam sim no, cov khoom siv tub rog thiab tub ceev xwm thoob ntiaj teb siv "ceramic insert + UHMWPE / aramid" cov qauv sib xyaw. Suav mos mos vests, leveraging qhov zoo ntawm tag nrho cov kev lag luam saw thiab nruj qauv (dent tsawg dua los yog sib npaug zos rau 25 hli), yog 30% sib dua thiab 60% pheej yig dua European thiab American cov khoom rau tib theem ntawm kev tiv thaiv. Lawv tau raug xa tawm mus rau ntau dua 30 lub teb chaws thiab tau dhau los ua qhov kev xaiv muaj txiaj ntsig tau pom zoo hauv kev sib ntaus sib tua tiag tiag.
