Cov yam ntxwv tseem ceeb
Ultra-siab kub ceramic precursor yog cov organic-inorganic hybrid polymer cov khoom tsim nrog ultra-siab kub hlau ntsiab ua lub ntsiab tivthaiv. Nws yog ib qho tseem ceeb raw khoom rau kev npaj ntawm ceramic matrix composite cov ntaub ntawv, ceramics fibers, thiab ceramic coatings. Tshwj xeeb, nws suav nrog ntau lub npe xws li zirconium carbide precursor thiab hafnium-tantalum carbon precursor, uas muaj qhov zoo ntawm cov ntsiab lus hlau siab thiab kev siv tau zoo ntawm cov txheej txheem PIP, thiab tuaj yeem ua tau raws li qhov xav tau ntawm huab cua kub siv ib puag ncig.
Daim ntawv thov teb
Feem ntau yog siv los ua cov matrix ntawm ultra-siab kub ceramic matrix cov ntaub ntawv sib xyaw, uas tuaj yeem ua tau raws li qhov kub thiab txias tsis kam, oxidation tsis kam, erosion resistance thiab load-bearing yuav tsum ntawm cov ntaub ntawv hauv kev siv ib puag ncig saum 2000 degree. Ceramic matrix composite cov ntaub ntawv yog ib hom kev nruam fiber-toughened ceramic cov ntaub ntawv uas kov yeej cov teeb meem ntawm cov tsoos ceramics xws li siab brittleness thiab tsis muaj kev ntseeg siab, thiab ua tau raws li cov kev xav tau ntawm engineering daim ntaub ntawv. Ceramic matrix composite matrix plays lub luag haujlwm hauv kev tiv thaiv fibers, muab tag nrho cov khoom tawv tawv, thiab tiv thaiv tshav kub, dej, oxygen, thiab airflow yaig nyob rau hauv ib puag ncig siv. Nws yog ib qho tseem ceeb ntawm cov khoom siv ceramic matrix, suav txog ntau dua 30% ntawm nws cov ntim. Cov txheej txheem ceramic precursor impregnation yog txheej txheem xaiv rau heterogeneous loj-loj ceramic matrix composites. Cov txheej txheem kev ua tau zoo thiab kev siv kev ua haujlwm ntawm ceramic precursor ua lub luag haujlwm txiav txim siab hauv kev ua tiav ntawm cov ceramic matrix composite. Lub tuam txhab ultra-high kub ceramic precursor khoom technology los ntawm Suav Academy ntawm Sciences thiab tau dav siv nyob rau hauv lub aerospace teb. Lub tuam txhab muaj kev pabcuam tomqab muag tiav thiab cov khoom lag luam muaj peev xwm txhim kho ntxiv, thiab tuaj yeem lees txais kev hloov kho ntawm precursors nrog cov khoom tshwj xeeb.
