Lub ntiaj teb muaj zog tshaj cov khoom ua npuas ncauj - ceramic pob hlau ua npuas ncauj

Hauv daim ntawv no, peb yuav qhia txog cov khoom muaj feem thiab daim ntawv thov scenarios ntawm ceramic pob puasua npuas ncauj hlau(aluminium-based) cov khoom siv ultralight.
Ua ntej ntawm tag nrho cov, cov khoom yog ib tug tshwj xeeb composite tshiab ua npuas ncauj khoom. Los ntawm implanting hollow ceramic particles teem nyob rau hauv ib tug matrix raws li cov khoom txhawb zog, tag nrho cov modulus thiab lub zog ntawm cov khoom yog ho siab dua lwm yam ntaub ntawv ua npuas ncauj ua los ntawm tib lub matrix. Cov khoom siv txhawb nqa muab cov khoom ua npuas ncauj nrog cov porosity ntau dua li cov khoom siv matrix alloy, uas ua rau muaj qhov hnyav hnyav. Thiab ntxiv rau qhov txo qhov hnyav, muaj qhov sib npaug ntawm cov khoom siv hluav taws xob sib xyaw ua ke hauv cov khoom siv ua npuas dej ua kom ua tiav lub zog nqus hauv compression.
Qhov thib ob, cov qauv ntxeem tau ntawm cov ceramic spheres puas ua npuas ncauj aluminium ultralight khoom tuaj yeem tiv taus cov yas deformations loj thiab nws tuaj yeem nqus tau lub zog hauv compression lossis cuam tshuam cov xwm txheej tsim. Nws muaj peev xwm damping zoo tuaj yeem siv los txo kev co. Yog li ntawd, nws tuaj yeem siv los ua cov khoom siv tiv thaiv kev puas tsuaj los ntawm kev sib tsoo lossis kev cuam tshuam los ntawm kev txi nws tus kheej.
Hauv cov ntsiab lus, cov khoom siv pob zeb ceramic ua npuas dej yog tam sim no feem ntau muaj peev xwm thov ntawm cov hlau ua npuas ncauj, thiab tau dhau los ua tus neeg sawv cev zoo tshaj plaws ntawm cov ntaub ntawv tshiab-kev ua haujlwm sib koom ua ke thiab niaj hnub no cov khoom siv kev loj hlob.
Khoom siv tau zoo

1. Lub teeb yuag
Cov khoom siv sib sib zog nqus yog ib qho ntawm qhov zoo ntawm cov pob ceramic nocomposite ua npuas ncauj hlaucov khoom siv ultralight. Tam sim no, cov khoom siv no feem ntau yog siv txhuas lossis magnesium alloy nrog lub teeb ntom thiab lub zog zoo heev raws li cov khoom siv hauv paus. Qhov kev txhawb zog yog feem ntau nyias-walled ceramic hollow spheres, uas yog qhov tsim nyog rau ntxiv tau cov ntaub ntawv ua npuas ncauj nrog qis dua. Kev cog qoob loo ntawm hollow ceramic spheres pab txhawb kev txhawb nqa ntawm cov pores sab hauv ntawm cov khoom siv thiab tseem txhim kho lub zog tag nrho ntawm cov khoom, muab qhov zoo tshaj plaws porosity rau cov khoom ua npuas ncauj. Nws muab ntau yam kev siv hauv kev tsim cov nkoj nkoj, qhov chaw tsheb, buoyancy modules, thiab tsheb armor.

2. Kev ntxhov siab-txoj kab nkhaus
Rau lub teeb yuag ceramic pob reinforced aluminium matrix composites, lub ntsiab mechanical feature ntawm cov khoom yog reflected nyob rau hauv nws compressive zog. Vim nws cov txheej txheem tsis ua hauj lwm thiab cov txheej txheem thaum lub sij hawm compression, uas txawv kiag li ntawm cov khoom siv matrix, nws cov khoom compression zoo ib yam li cov ntaub ntawv ntxeem tau. Thaum cov khoom siv sib xyaw ua ke yuav ua tsis tau sai tom qab yielding, hlau sib xyaw foams yuav txuas ntxiv deform ntau thiab nqus tau ntau lub zog sab nraud tom qab lawv pib tawm. Cov khoom compressive ntawm cov khoom tseem cuam tshuam los ntawm qhov loj ntawm cov pob zeb ceramic.

3. Shock absorption thiab lub zog nqus cov khoom
Tam sim no, feem ntau siv hauv kev vibration damping thiab lub zog nqus yog ntau yam ntaub ntawv polymer ua npuas ncauj. Txawm li cas los xij, cov khoom siv polymer ua npuas nws tus kheej yog qhov nkag siab rau qhov kub thiab txias, tshuaj reagents thiab ultraviolet rays, uas txwv tsis pub siv cov ntaub ntawv polymer ua npuas ncauj hauv qhov chaw. Thiab qhov tsis zoo ntawm qhov tshwj xeeb qis zog nqus kuj ua rau cov ntaub ntawv polymer ua npuas ncauj xav tau lub ntim loj kom nqus tau qhov loj ntawm lub zog. Piv nrog rau nws,ua npuas ncauj aluminiummuaj zog dua thiab ntau dua rigidity. Nws muaj kev ruaj ntseg siab, zoo marble tsis kam, muaj zog rov tsim dua tshiab, tsis yooj yim rau hlawv, lub teeb yuag, yog ib qho khoom siv zoo heev.

4. Daim ntawv thov hauv engineering
Ceramic pob Composite ua npuas ncauj aluminium ultralight khoom, kuj muaj ntau daim ntawv thov nyob rau hauv lub teb ntawm engineering. Ntawm qhov tod tes, nws yog siv los ua cov khoom siv, siv hauv kev lag luam automotive, aerospace, thiab kev tsim kho kev lag luam; Ntawm qhov tod tes, nws yog siv los ua cov khoom siv ua haujlwm, dhau los ua lub zog nqus thiab poob siab absorbing thiab electromagnetic shielding Cheebtsam.
