(1) Thaum tshav kub kub-insulating cov khoom siv ua haujlwm
Cov txheej txheem tseem ceeb ntawm cov txheej txheem rau aerospace high-performance structural functional integratedcov ntaub ntawv kub-insulatingyog RTM (Resin Transfer Molding), molding, thiab layup, thiab lwm yam. Qhov project no siv ntau txoj kev molding tshiab.
Kev ua haujlwm RTM:
① Tso cov ntaub fiber ntau: cov ntaub quartz fiber ntau tau muab tso rau hauv pwm kab noj hniav ib zaug;
② Resin txhaj tshuaj: resin thiab catalyst yog tov nyob rau hauv lub static tov khoom nyob rau hauv pem hauv ntej ntawm lub txhaj tshuaj phom thiab txhaj rau hauv pwm kab noj hniav uas muaj fiber ntau daim ntaub.
③ Resin curing: pwm kab noj hniav yog rhuab nyob rau hauv thiaj li yuav ua kom lub curing ntawm resin;
(iv) Cov khoom demolding: Tom qab cov resin kho thiab molded, lub pwm yog qhib kom tau qhov kawg composite tivthaiv.
Tom qab cov txheej txheem RTM (Resin Transfer Molding), cov ntaub ntawv quartz fiber ntau tau ua tiav thiab teeb tsa nrog lub plhaub hlau, thiab cov khoom lag luam tom qab teeb tau tsim nyog tom qab qhov kev xeem, uas yog cov khoom tiav.
(2) Wave-pob tshab cov ntaub ntawv sib xyaw
Quartz fiber reinforcedceramic yoj-pob tshab composites npaj los ntawm cov organic precursor impregnation cracking method (PIP).PIP txoj kev yog siv cov organic precursor impregnated fiber preforms, thiab ces pyrolysis, zus tau tej cov quartz fiber matrix tso rau hauv preform blanks ntawm lub billet, nyob rau hauv lub billet tom qab. tshuaj tsuag pleev xim kho rau nws qhov kev tshuaj xyuas, tshuaj xyuas thiab kev tsim nyog uas yog cov khoom tiav. Txhawm rau kom ntseeg tau tias cov khoom siv saum npoo ntawm qhov xav tau qhov kub thiab txias yog qis dua li cov txheej txheem kub xovxwm sintering, tuaj yeem txo qhov kev puas tsuaj rau quartz fibers, thiab muaj cov yam ntxwv ntawm qhov ze-net shaping, tshwj xeeb tshaj yog tsim rau kev npaj loj. -size wave-pob tshab khoom Cheebtsam.
(3) Cov khoom siv rwb thaiv tsev tshwj xeeb
Covquartz fiber ntaubyuav tau npaj rau hauv pwm kab noj hniav, cov resin yuav raug txhaj rau hauv pwm kab noj hniav kom nws muaj fiber ntau daim kab noj hniav kab noj hniav, cua sov lub pwm kab noj hniav thiaj li yuav ceev cov resin curing, resin curing molding, qhib pwm thiab tau txais. qhov kawg tshwj xeeb insulating haumxeeb ntaub ntawv.
