Raws li cov txheej txheem sib txawv, cov ntaub ntawv txhuas txhuas phaj sib xyaw yog muab faib ua fiber ntau thiab equiaxed nplej nrog particle diameters ntawm 05100m) cov ntaub ntawv siv cov khoom siv hlau nplaum. Fiber-reinforced alloy aluminium composite cov ntaub ntawv muaj xws li cov fiber ntau txuas ntxiv (inch ntawm 3 ~ 140qm, nam piv ntau dua 1000) reinforced, luv fiber ntau los yog whisker (inch ntawm 01 ~ 20gm, nam ratio nyob ib ncig ntawm 50) reinforced alloy aluminium composite cov ntaub ntawv.
Cov tshuab siv los ntxiv dag zog txuas ntxiv fiber ntau-txhim kho alloy txhuas cov ntaub ntawv feem ntau suav nrog Ming fiber, alumina fiber, silicon carbide fiber, carbon fiber thiab lwm yam alloy aluminium composite cov ntaub ntawv. Cov khoom siv thiab kev siv ntawm txhua cov khoom siv aluminium alloy yog pom nyob rau hauv Table 1. Los ntawm Table 1, nws tuaj yeem pom tau tias tsis tu ncua ntxiv dag zog alloy aluminium Composite cov ntaub ntawv muaj cov khoom zoo heev thiab tau pom zoo rau daim ntawv thov muaj peev xwm ua kom muaj zog, cov ntaub ntawv kub-resistant hauv aerospace, tub rog thiab lwm yam.
Whisker-reinforced alloy aluminium phaj composite cov ntaub ntawv muaj lub zog tshwj xeeb, tshwj xeeb modulus, zoo thermal stability, qaug zog tsis kam, hnav tsis kam thiab lwm yam khoom zoo heev. Lawv tau tsim sai heev thiab dhau los ua ib ceg tseem ceeb ntawm cov khoom siv aluminium alloy. Cov kev tshawb fawb yav dhau los tau tsom mus rau kev siv Sic thiab SiN ua cov theem ntxiv. Nyob rau xyoo 1990, cov kws tshawb nrhiav thawj zaug kawm txog txhuas borate whisker-reinforced alloy aluminium composites. Tom qab ntawd, kuv lub teb chaws lub koom haum ntawm Kev Tshawb Fawb Hlau kuj tau kawm thiab siv txhuas borate whiskers. Tsim cov phiaj xwm loj ntau lawm. Tsis ntev los no, tib neeg tau ua tiav ib qho kev txhawb nqa sab nrauv phab ntsa annular groove diesel cav piston siv cov nqi qis dua potassium titanate whisker-reinforced aluminium alloy kawm nyob rau hauv xyoo tas los.
Cov txheej txheem txhawb zog ntawm cov khoom siv hluav taws xob ntxiv cov khoom siv aluminium feem ntau suav nrog SiC, TiC, A12O3 thiab graphite hais, uas daws qhov teeb meem ntawm kev npaj kim kim ntawm fiber ntau cov khoom siv aluminium alloy. Ntxiv mus, cov khoom sib xyaw yog isotropic, uas daws qhov teeb meem hauv kev npaj. Muaj ntau yam tsis zoo uas cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, xws li kev puas tsuaj fiber ntau, microstructure tsis sib xws, kev sib cuag ntawm fiber ntau, thiab cov tshuaj tiv thaiv ntau dhau. Particle-reinforced alloy aluminium phaj composite cov ntaub ntawv tuaj yeem siv dav hauv aerospace, tub rog, tsheb, hluav taws xob, khoom siv ncaws pob, thiab lwm yam.
