Xyoo 2021, tus kabmob tshiab no tseem hnyav heev, thiab kev loj hlob ntawm kev lag luam thoob ntiaj teb raug txwv hnyav. Txawm li cas los xij, tus kab mob tshiab no tsis tuaj yeem tso tseg qhov kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis. Cov khoom siv tub rog yog qhov yooj yim tshaj plaws thiab kev siv thev naus laus zis. Nyob rau hauv lub traction ntawm txoj kev loj hlob xav tau kev pab ntawm cov cuab yeej hloov, lub tseem ceeb tshaj plaws technology breakthrough yog tseem zoo kawg li. Hauv peb lub xyoos dhau los, peb tau ua tiav qhov "Kev Txhim Kho Loj ntawm Cov Tub Rog Txawv Tebchaws Cov Khoom Siv Hluav Taws Xob". Los ntawm kev txheeb xyuas cov txheej txheem thev naus laus zis hauv kev ua tub rog cov ntaub ntawv hauv xyoo no, peb tau xaiv kaum lub thev naus laus zis nrog kev cuam tshuam tseem ceeb, thiab txiav txim siab txog kev txhim kho yav tom ntej ntawm cov ntaub ntawv, txhawb cov neeg nyeem thiab cov neeg nyeem. Cov kws tshawb fawb tshawb fawb, muab lub platform rau kev sib tham. Peb xyoos dhau los, txoj haujlwm no tau ua tiav cov lus teb zoo.
Xyoo 2021, kev txhim kho lub zog ntawm cov ntaub ntawv sib xyaw yuav muaj zog, thiab lawv yuav ua tau zoo hauv kev tshawb nrhiav hauv kev lag luam aerospace thiab riam phom; rau qhov sib txawv daim ntawv thov ib puag ncig, cov ntaub ntawv tshiab xws li cov hluav taws xob ua haujlwm siab thiab hnav tsis kam yuav tshwm sim; 2nm txheej txheem chips yuav teeb hluav taws xob. Ntawm qhov taw tes siab ntawm kev txhim kho cov ntaub ntawv ua haujlwm, cov ntaub ntawv bismuth tau qhib txoj hauv kev rau 1nm txheej txheem chips. Tsis tas li ntawd, qhov kev taw qhia ntawm cov txheej txheem tshiab kuj tseem ua rau kev tshawb pom ntawm ntau yam inorganic tebchaw thiab high-entropy alloy cov ntaub ntawv uas cia siab rau cov khoom tsim.
Thaum Lub Ib Hlis 19, 2022, Tuam Tshoj Aviation Industry Development Research Center tau teeb tsa cov kws tshaj lij hauv Beijing los ua txoj haujlwm xaiv ntawm "Qhov Tseem Ceeb Ntawm Cov Tub Rog Txawv Tebchaws hauv 2021". Los ntawm tag nrho ntawm 158 txoj kev loj hlob nyob rau hauv tsib lub teb, suav nrog cov khoom siv hlau ua tau zoo, cov khoom siv sib xyaw ua ke, cov khoom siv tshwj xeeb, cov ntaub ntawv siv hluav taws xob ua haujlwm, thiab cov ntaub ntawv tseem ceeb, cov nram qab no kaum qhov tseem ceeb tshaj plaws yog xaiv los siv los ntawm cov koom haum txiav txim siab, scientific research units thiab nyeem.
Teb Chaws Asmeskas Tub Rog Tub Rog tau ua tiav qhov kev txuas ntxiv fiber ntau 3D tshuab luam ntawv tis tis
Kev tsim sai sai thiab tus nqi qis hloov pauv hloov pauv yog qhov tseem ceeb rau kev txhim kho tam sim no ntawm cov ntaub ntawv carbon fiber ntau. Lub US Air Force Research Laboratory tau tsom ntsoov rau kev siv tshuab fiber ntau 3D tshuab luam ntawv txuas ntxiv, vam tias nws tuaj yeem dhau los ua kev siv thev naus laus zis los hloov cov txheej txheem tsim khoom sib xyaw, txo tus nqi thiab lub sijhawm ua cov khoom sib xyaw. Thaum lub Plaub Hlis 2021, US Continuous Composites tau siv nws cov patented nruam fiber ntau 3D tshuab luam ntawv (CF3D) kom ua tiav ob 2.4-meter-ntev, 1.8-kilogram carbon fiber composite spar assemblies, ua kom tiav US Air Force Research Laboratory.
Ob xyoos Wing Structure Design for Manufacturing (WiSDM) cog lus. Cov txiaj ntsig zoo li qub ntawm qhov kawg tis sib dhos nto, lub tis tag nrho tau thauj khoom mus rau 160% ntawm qhov tsim txwv load. Tsis muaj kev ntsuas lossis qhov pom kev puas tsuaj rau CF3D luam tawm spars raug kuaj pom. Cov luam ntawv carbon fiber spar ua tiav ib feem ntawm fiber ntau ntawm 60% nrog kwv yees li 1% -2% voids.
Txoj kev tsim cov khoom sib xyaw tshiab no nta hauv qhov chaw impregnation, sib sau ua ke thiab kho, uas txo cov nqi thiab cov sij hawm txhuas. Cov txheej txheem automated tag nrho nta txiav thiab rov ua dua rau ply poob thiab qhov sib txawv ntawm qhov tuab hauv cov qauv. Qhov project, uas optimizes oriented structural fibers, yog ib tug ua tau zoo zaj dab neeg siv ib tug kev cai CF3D cov ntaub ntawv tov, nrog rau kev cuam tshuam rau kev tsim cov khoom kim heev aerospace structural qhov chaw.
