Torayca Carbon Fiber thiab Prepregs muab los ntawm Toray rau H3 Launch Tsheb
Toray Industries tau tshaj tawm nws qhov kev muab Torayca carbon fiber thiab prepreg cov ntaub ntawv rau JAXA lub H3 tso tsheb, ua tiav H-IIA foob pob hluav taws. Cov pa roj carbon fiber ntau, raws li siv nyob rau hauv H-IIA, tau muab tso rau hauv H3 cav casings, uas yog cov khoom ntawm lub foob pob hluav taws lub cev uas muaj roj thiab ua raws li combustion chamber. Tsis tas li ntawd, Torayca prepreg, featuring high-strength carbon fibers, tau tshiab siv rau lub payload fairing-pem hauv ntej ntug ntawm lub launching tsheb uas nqa satellites thiab lwm yam payloads-nrog ib tug high-tughness resin.
Lub H3 yog JAXA qhov kev tshaj tawm tshiab tshaj tawm lub tsheb, tsim kho kom zoo dua qub, kev ntseeg siab, thiab kev ua haujlwm zoo. Sawv ntawm 63 meters siab nrog ib txoj kab uas hla ntawm 5.2 meters, lub foob pob ua ntxaij muaj peev xwm, raws li JAXA cov specifications, xa "4 tons los yog ntau tshaj" rau lub hnub-synchronous orbit ntawm qhov siab ntawm 310 mais (500 kilometers) thiab "6.5 tons. los yog ntau dua" mus rau qhov chaw hloov chaw geostationary.
Lub Torayca prepreg ua hauj lwm rau lub fairing yog ib tug unidirectional daim kab xev prepreg tailored rau lub Automated Fiber Placement (AFP) txheej txheem. Tshaj li cov pa autoclave curing, cov khoom siv no ua kom muaj txiaj ntsig zoo thiab ua haujlwm ntawm cov geometry nyuaj thiab cov qauv loj, suav nrog cov kho hauv qhov cub.
Toray tau pom tias kev siv cov satellites thoob plaws ntau qhov chaw-xws li kev tshaj tawm thiab kev sib txuas lus mus rau qhov chaw, kev soj ntsuam lub ntiaj teb, thiab kev tiv thaiv kev puas tsuaj- tau loj hlob, ua rau muaj kev xav tau ntau xyoo rau kev tsim tsheb. Raws li kev lag luam nrhiav tus nqi qis dua thiab kev ua tau zoo dua qub, kev siv cov ntaub ntawv sib xyaw yog cia siab tias yuav nthuav dav ntxiv. Toray tseem cog lus los txhawb cov kev xav tau hloov zuj zus los ntawm nws cov khoom Torayca.
