Sintered silicon carbide ceramics thiab silicon carbide ceramic bulletproof khoom series

Sintered SiC Ceramics: Qhov zoo ntawm SiC Ceramic Ballistic khoom

Silicon carbide ceramic bulletproof khoomtau dhau los ua ntau thiab nrov hauv kev tiv thaiv tus kheej thiab tub rog vim lawv qhov kev ua tau zoo thiab kev ua tau zoo. Cov ceramics muaj SiC cov ntsiab lus ≥99% thiab hardness (HV0.5) ≥2600, ua rau lawv cov khoom ntawm kev xaiv rau ballistic daim ntaub ntawv xws li mos txwv vests thiab tiv thaiv iav rau tso tsheb hlau luam thiab armored tsheb.

Cov khoom tseem ceeb ntawm cov koob no yog silicon carbide ceramic bulletproof ntawv. Nws qis ntom ntom thiab lub teeb yuag ua rau nws haum rau cov tub rog cov tub rog cov khoom lag luam, tshwj xeeb tshaj yog cov khoom siv sab hauv ntawm cov kab ke sab hauv. Tsis tas li ntawd, nws muaj cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm ntev, lub zog thiab thermal stability.

Silicon carbide (SiC) ceramics muaj ob lub qauv siv lead ua, cubic β-SiC thiab hexagonal α-SiC. Cov ceramics muaj zog covalent bonds, zoo mechanical zog, oxidation tsis kam, hnav tsis kam thiab qis coefficient ntawm kev sib txhuam dua lwm yam ceramics xws li alumina thiab boron carbide. Lawv cov thermal conductivity, me me coefficient ntawm thermal expansion, thiab zoo heev tiv thaiv thermal shock thiab tshuaj corrosion ntxiv pab txhawb lawv cov kev siv dav.

Lub hauv paus ntsiab lus ntawm mos mos ntawm silicon carbide ceramics nyob rau hauv nws lub peev xwm los dissipate thiab nqus mos mos zog. Thaum cov khoom siv engineering ib txwm nqus lub zog los ntawm cov yas deformation, cov ntaub ntawv ceramic, suav nrog silicon carbide, ua li ntawd los ntawm microfractures.

Lub zog nqus cov txheej txheem ntawm silicon carbide bulletproof ceramics tuaj yeem muab faib ua peb theem. Thaum lub sij hawm thawj zaug cuam tshuam, cov mos txwv hits ceramic nto, dulling lub mos txwv thiab crushing ceramic nto, tsim me me, nyuaj fragmented cheeb tsam. Thaum lub sij hawm yaig, cov mos txwv blunt txuas ntxiv mus rau qhov chaw khib nyiab, tsim ib txheej txuas ntxiv ntawm cov khib nyiab ceramic. Thaum kawg, thaum lub sij hawm deformation, tawg thiab tawg, cov ceramic yog raug rau tensile stresses, ua rau nws qhov kawg rupture. Tom qab ntawd lub zog ntxiv yog dissipated los ntawm deformation ntawm cov ntaub ntawv backplate.

Cov khoom zoo heev no thiab cov txheej txheem peb-theem lub zog nqus tau ua rau cov khoom siv silicon carbide ceramic ballistic kom muaj txiaj ntsig zoo rau kev cuam tshuam ntawm cov mos txwv thiab ua rau lawv tsis muaj mob. Qhov kev ntsuam xyuas mos txwv tau mus txog Asmeskas tus qauv qib 4, uas muab kev tiv thaiv ntau tshaj plaws thiab yog thawj qhov kev xaiv ntawm cov kws tshaj lij tub rog hauv ntiaj teb.

Raws li cov ntsiab lus, sintered silicon carbide ceramics thiab silicon carbide ceramic bulletproof khoom series muaj qhov tshwj xeeb zoo ntawm cov khoom siv hluav taws xob, thermal stability, thiab bulletproof efficiency. Nrog lawv cov khoom zoo tshaj plaws, cov ceramics no tau siv dav los ua cov ntaub ntawv hauv ob sab phlu rau cov mos txwv vests thiab cov cuab yeej tiv thaiv rau cov tso tsheb hlau luam thiab tsheb armored. Lawv lub ntom ntom ntom ntom ntom ntom thiab lub teeb ci ntsa iab ua rau lawv zoo tagnrho rau kev tiv thaiv tus kheej. Raws li kev siv thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias yuav muaj kev txhim kho ntxiv thiab kev siv ntawm cov ceramics zoo kawg li hauv kev tiv thaiv tus kheej thiab tub rog.
