Impact resistance test ntawm cov khoom sib xyaw
1. Kev sim ntsuas qhov cuam tshuam qis
Txhawm rau simulate qhov cuam tshuam tus cwj pwm ntawm cov ntaub ntawv nyob rau hauv cov xwm txheej tiag tiag, cov kws tshawb fawb tau npaj ntau txoj hauv kev sim.Raws li qhov tseeb ntawm qhov kev cuam tshuam, qhov cuam tshuam feem ntau muab faib ua kev cuam tshuam kev kub ceev thiab kev cuam tshuam qis.
Kev kub ceev kuj tseem hu ua ballistic impact.Vim tias qhov cuam tshuam ntawm kev kub ceev tau txais kev saib xyuas tseem ceeb hauv aerospace thiab kev ua tub rog, tib neeg tau ua ntau yam kev tshawb fawb txog kev cuam tshuam kev kub ceev.Kev kub ceev feem ntau yog siv lub tshuab loj me me los ntaus cov khoom ntawm qhov nrawm dua, thiab feem ntau yog siv cov phom cua los tua cov phiaj xwm los kawm txog cov kev cuam tshuam ntawm cov khoom siv sib xyaw, raws li pom hauv daim duab:
Kev ntsuas qhov ntsuas qis qis feem ntau simulates qhov cuam tshuam ntawm cov khoom loj ntawm qhov chaw ntawm cov khoom ntawm qhov qis dua, xws li kev poob qis ntawm lub cuab yeej thaum kho, thiab qhov ntsuas qhov poob qis feem ntau yog siv rau kev sim. simulation.
Daim duab 2 Drop rauj test device
Cov txiaj ntsig kev tshawb fawb pom tau tias cov duab, qhov zoo thiab qhov nrawm ntawm qhov projectile yuav muaj kev cuam tshuam loj rau kev ua haujlwm tsis ua haujlwm ntawm cov khoom sib xyaw.Piv txwv li, cov kws tshawb fawb tau ua ntau yam kev tshawb fawb txog kev sib raug zoo ntawm cov duab ntawm lub taub hau rauj thiab kev cuam tshuam tus cwj pwm ntawm cov khoom sib xyaw.Feem ntau hais lus, lub taub hau rauj yog siv ntau dua, qhov ntau hauv cheeb tsam cuam tshuam kev puas tsuaj ntawm cov khoom, thiab lub ntsiab tsis ua hauj lwm hloov pauv ntawm delamination mus rau matrix tsis ua hauj lwm thiab kev puas tsuaj.Fiber tawg.
2. Kev cuam tshuam ntawm ib puag ncig yam cuam tshuam rau kev ua haujlwm qis qis
Cov khoom sib xyaw ua ke yuav tsum muaj kev cuam tshuam ib puag ncig zoo thaum siv mus sij hawm ntev, xws li qhov kub thiab txias, tsis tshua muaj kub, ntub dej kub, thiab thermal cycles.Cov kev tshawb fawb tau pom tias nyob rau hauv qhov kev ua ntawm cov cheeb tsam no, cov khoom siv ntawm cov khoom sib xyaw yuav hloov pauv loj heev.Thermal cycling feem ntau txo cov dabtsi yog khoov thiab transverse tensile lub zog ntawm cov khoom sib xyaw, thiab tsim kom muaj ntau ntawm microcracks hauv matrix.
Feem ntau siv ib puag ncig pretreatment thiab kev simulation ib puag ncig los kawm txog kev cuam tshuam ntawm ib puag ncig.Lub thiaj li hu ua ib puag ncig pretreatment yog muab cov khoom sib xyaw kom raug kuaj nyob rau hauv ib puag ncig rau kev ua ua ntej, thiab tom qab ntawd muab cov khoom ua tiav mus rau qhov ntsuas qis qis hauv chav tsev kub.Kev simulation ib puag ncig yog muab cov khoom sib xyaw rau hauv ib puag ncig chamber thaum cuam tshuam.Txoj kev no yog siv los kawm txog qhov cuam tshuam kev ua tau zoo ntawm cov khoom hauv cov chaw pabcuam sib txawv.
3. Cov nyhuv ntawm cov khoom siv rau kev ua haujlwm qis qis
Fiber ntau yog siv los ua kev txhawb nqa hauv kev tsim cov khoom sib xyaw.Nyob rau tib lub sijhawm, raws li lub luag haujlwm tseem ceeb ntawm kev thauj khoom, cov khoom siv fiber ntau muaj kev cuam tshuam zoo rau tag nrho cov kev cuam tshuam tsis zoo ntawm cov khoom sib xyaw.Cov fibers siv hauv kev lag luam aerospace feem ntau suav nrogcarbon fiber ntau, iav fiberthiab Kevlar fiber ntau.Vim yog qhov tshwj xeeb brittleness ntawm carbon fiber, qhov cuam tshuam tsis kam ntawm carbon fiber reinforced resin matrix composites tsis muaj zog dua li cov iav fiber ntau thiab Kevlar fiber.
Lub matrix ntawm fiber-reinforced resin-based composite cov ntaub ntawv plays lub luag haujlwm tseem ceeb hauv cov ntaub ntawv sib xyaw.Cov resin matrix yog inseparable los ntawm seb nws puas yog mus rau kis load, tswj lub orientation ntawm fibers los yog tswj cov kev ncaj ncees ntawm cov khoom.Cov txiaj ntsig ntawm txoj kev tshawb fawb qhia tau hais tias txawm hais tias cov khoom siv ntawm cov thermosetting resins zoo dua li cov thermoplastic resins, qhov sib txuas ntawm cov qauv molecular ntawm thermosetting resins ua rau lawv tsis tshua muaj zog, uas ua rau lawv muaj kev cuam tshuam ntau dua hauv kev cuam tshuam.
Lub interface plays lub luag haujlwm ntawm kev xa mus rau cov khoom siv fiber ntau hauv cov khoom sib xyaw, yog li kev ua haujlwm ntawm lub interface yuav cuam tshuam rau tag nrho kev ua haujlwm ntawm cov khoom sib xyaw.Cov khoom sib xyaw uas tsis zoo cuam tshuam kev sib txuas ntawm fiber ntau thiab matrix yuav qhia qis zog thiab nruj, thiab kev sib raug zoo heev yuav ua rau cov khoom nkig.
