(1) Cov khoom siv ua haujlwm kub-insulating
Cov txheej txheem txheej txheem tseem ceeb rau kev ua haujlwm siab hauv aerospace thiab kev ua haujlwm sib xyaw ua kecov ntaub ntawv rwb thaiv tshav kubyog RTM (Resin Transfer Molding), molding, thiab layup, thiab lwm yam. Qhov project no siv cov txheej txheem molding tshiab ntau yam.
Kev Ua Haujlwm RTM:
① Tso cov ntaub fiber: cov ntaub quartz fiber uas tau npaj tseg lawm muab tso rau hauv qhov pwm ib zaug;
② Kev txhaj tshuaj resin: resin thiab catalyst raug sib xyaw rau hauv lub tshuab sib tov static ntawm pem hauv ntej ntawm rab phom txhaj tshuaj thiab txhaj rau hauv qhov pwm uas npog nrog daim ntaub fiber.
③ Kev kho cov tshuaj resin: lub pwm qhov yog cua sov kom ua kom cov tshuaj resin kho sai dua;
(iv) Khoom demolding: Tom qab cov resin kho thiab pwm, cov pwm qhib kom tau txais cov khoom sib xyaw kawg.
Tom qab RTM (Resin Transfer Molding) txheej txheem, daim ntaub quartz fiber raug ua tiav thiab teeb tsa nrog lub plhaub hlau, thiab cov khoom tom qab teeb tsa tau tsim nyog tom qab kev xeem kev ua tau zoo, uas yog cov khoom tiav.

(2) Cov ntaub ntawv sib xyaw ua ke uas muaj cov duab pob tshab
Quartz fiber ntxiv dag zogCov khoom sib xyaw ua los ntawm cov khoom siv ua los ntawm cov organic precursor impregnation cracking method (PIP). Txoj kev PIP yog siv cov organic precursor impregnated fiber preforms, thiab tom qab ntawd pyrolysis, kev tsim cov quartz fiber matrix tso rau hauv cov preform blanks ntawm lub billet, hauv lub billet tom qab tshuaj tsuag pleev xim rau nws qhov kev tshuaj xyuas, kev tshuaj xyuas thiab kev tsim nyog uas yog cov khoom tiav. Txhawm rau kom ntseeg tau tias qhov kub ntawm cov khoom siv uas xav tau qis dua li cov txheej txheem sintering kub ib txwm muaj, tuaj yeem txo qhov kev puas tsuaj rau cov quartz fibers, thiab muaj cov yam ntxwv ntawm kev sib tsoo ze-net, tshwj xeeb tshaj yog tsim rau kev npaj cov khoom siv loj-loj-pob tshab.

(3) Cov ntaub ntawv rwb thaiv tsev tshwj xeeb
Lubdaim ntaub fiber quartzyuav raug npaj rau hauv qhov pwm qhov, cov tshuaj resin yuav raug txhaj rau hauv qhov pwm qhov kom nws puv nrog cov ntaub fiber ntau qhov pwm qhov, cua sov qhov pwm qhov kom ua kom cov tshuaj resin kho sai dua, cov tshuaj resin kho molding, qhib lub pwm thiab tuaj yeem tau txais cov ntaub ntawv tshwj xeeb kawg.
