Cov txheej txheem autoclave suav nrog kev tso cov prepregs raws li cov lus qhia layup hauv ib lub pwm, kaw lawv rau hauv lub hnab nqus tsev, thiab tom qab ntawd muab cov khoom sib dhos rau hauv autoclave. Los ntawm kev cua sov thiab kev nias hauv cov khoom siv autoclave, cov khoom siv dhau los ua qhov tshuaj tiv thaiv, hloov cov prepreg dawb mus rau hauv cov duab xav tau thaum ua tau raws li qhov yuav tsum tau ua rau cov khoom.

Cov txiaj ntsig ntawm cov txheej txheem autoclave:

Kev faib tawm lub siab sib npaug hauv lub tank: Kev siv cua compressed, cov pa inert (N₂, CO₂), lossis cov pa sib xyaw ua kom muaj kev sib npaug ntawm lub siab rau txhua qhov chaw raws li cov kab ib txwm ntawm lub hnab nqus tsev. Qhov no ua rau muaj kev sib npaug ntawm lub siab thaum lub sijhawm tsim cov khoom thiab kho.

Qhov kub ntawm huab cua sib npaug hauv lub tank: Cov pa roj cua sov (lossis txias) ncig sai sai hauv lub tank, tswj cov kub ntawm cov pa roj sib npaug ntawm txhua qhov chaw. Nrog rau cov qauv pwm tsim zoo, qhov no ua kom muaj qhov sib txawv ntawm qhov kub tsawg kawg nkaus thoob plaws cov khoom thaum lub sijhawm cua sov thiab txias thaum kaw hauv pwm.

Kev siv tau dav: Tus qauv pwm yooj yim ua rau muaj kev ua haujlwm siab, ua rau nws tsim nyog rau kev tsim cov chaw loj xws li tawv nqaij, vaj huam sib luag, thiab plhaub. Nws tuaj yeem tsim ntau yam qauv thiab cov khoom sib txawv ntawm ntau qhov ntev. Qhov kub thiab txias thiab siab hauv lub autoclave tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm yuav luag txhua cov ntaub ntawv polymer matrix composite.

Cov txheej txheem tsim khoom ruaj khov thiab txhim khu kev qha: Lub siab thiab kub sib xws hauv lub autoclave ua kom cov khoom zoo sib xws. Cov khoom tsim los ntawm cov txheej txheem autoclave qhia txog qhov porosity qis thiab cov ntsiab lus resin sib xws. Piv rau lwm txoj kev tsim khoom, cov khoom tsim los ntawm autoclave muab cov khoom siv kho tshuab ruaj khov thiab txhim khu kev qha. Txog niaj hnub no, feem ntau ntawm cov khoom sib xyaw ua ke siab hauv cov ntawv thov aerospace yog tsim los ntawm kev siv cov txheej txheem autoclave.

Qhov tsis zoo ntawm cov txheej txheem autoclave:

Kev nqis peev thiab tus nqi siab: Piv rau lwm cov txheej txheem, cov txheej txheem autoclave loj, muaj cov qauv nyuaj, thiab raug cais ua cov hlab siab, ua rau kev tsim cov autoclave loj kim heev. Txhua lub voj voog kho siv ntau cov khoom siv pabcuam kim xws li lub hnab nqus tsev, cov gaskets kaw, cov yeeb yaj kiab tso tawm, cov lev permeable, thiab cov ntaub tso tawm. Tsis tas li ntawd, cov txheej txheem siv dej, hluav taws xob, thiab roj ntau heev.

Cov Ntawv Thov Tseem Ceeb ntawm Autoclave Txheej Txheem:

Aerospace: Cov tawv nqaij ntawm daim tawv nqaij, tav, thav ntawv, fairings, thiab lwm yam.

Tsheb: Cov vaj huam sib luag ntawm lub cev thiab cov khoom siv xws li cov vaj huam sib luag sab hauv / sab nraud, cov vaj huam sib luag qhov rooj sab hauv / sab nraud, cov vaj huam sib luag ru tsev, cov fenders, cov kab teeb, B-pillars, thiab lwm yam.

Kev thauj mus los ntawm tsheb ciav hlau: cov neeg pw tsaug zog, cov hlua khi, thiab lwm yam;

Kev lag luam marine, cov khoom siv siab heev, thiab lwm yam.

Cov txheej txheem autoclave yog txoj hauv kev tseem ceeb rau kev tsim cov khoom siv tas mus licov khoom sib xyaw ua los ntawm cov fiber ntauCov khoom sib xyaw. Siv dav hauv cov khoom siv thev naus laus zis siab xws li aerospace, kev thauj mus los ntawm tsheb ciav hlau, kev ua si nawv thiab kev lom zem, thiab lub zog tshiab, cov khoom sib xyaw ua ke tsim los ntawm autoclave suav txog ntau dua 50% ntawm tag nrho cov khoom sib xyaw. Hauv kev lag luam aerospace nkaus xwb, qhov feem pua ​​no tshaj 80%.

Cov Khoom Siv Pabcuam Nqus Tsev Rau Autoclaves

Daim Ntawv Thov Autoclave Molding Txheej Txheem

Raws li ib txoj kev tsim qauv uas tau txais kev pom zoo dav dav raucov khoom siv carbon fiberCov txheej txheem autoclave muaj cov kauj ruam hauv qab no:

Txheej Txheem Npaj

Qhov no feem ntau cuam tshuam nrog cov cuab yeej thiab kev npaj khoom siv, suav nrog cov pwm, carbon fiber prepregs, thiab cov ntaub ntawv pabcuam.

Kev Teeb tsa Khoom Siv

Cov kauj ruam no suav nrog kev txiav prepreg, txheej txheej, thiab kev sib zog. Cov prepregs carbon fiber raug txiav rau qhov loj me thiab qhov yuav tsum tau ua siv cov qauv lossis cov tshuab txiav tsis siv neeg. Cov pre-preg ces raug txiav rau qhov loj me xav tau, txheej txheej raws li cov qauv tsim, thiab thaum kawg ua ntej-compact. Tam sim no, cov khoom carbon fiber xws li cov raj, cov phaj, lossis lwm yam duab nyuaj feem ntau yog tsim los ntawm kev siv tes layup, muab kev ywj pheej siab.

Cov Txheej Txheem Npaj Kho

Cov kauj ruam no feem ntau yog siv lub hnab ntim cov khoom siv carbon fiber, txiav cov khoom siv pabcuam, thiab muab tso rau hauv. Feem ntau, kev npaj kho suav nrog kev npaj cov khoom, pwm, lub hnab nqus tsev, thiab cov khoom siv pabcuam. Cov khoom siv pabcuam tseem ceeb suav nrog cov neeg sawv cev tso tawm thiab cov khoom siv ua pa (siv los faib cov khoom nqus tsev kom sib npaug hauv lub hnab nqus tsev).

Kev Kho thiab Moulding

Kev kho kom zoo yog ib kauj ruam tseem ceeb rau txhua yam khoom siv carbon fiber. Nws cuam tshuam nrog kev ua kom sov thiab nias cov thermosetting resin hauv prepreg nyob rau hauv cov txheej txheem ruaj khov los tsim cov qauv network peb-seem ruaj khov. Rau cov khoom siv thermosetting carbon fiber, thaum kho lawm, txhua qhov tsis zoo uas tshwm sim los ntawm kev layup lossis cov txheej txheem kho yuav tsis rov qab tau. Yog li ntawd, kev tswj hwm nruj ntawm cov txheej txheem thaum lub sijhawm kho autoclave yog qhov tseem ceeb.

Kev Tshuaj Xyuas

Kev tshuaj xyuas feem ntau muaj peb txoj kev: kev tshuaj xyuas pom, kev kuaj ultrasonic, lossis kev kuaj X-ray tsis ua puas tsuaj. Tom qab kho, cov khoom siv carbon fiber raug tshuaj xyuas qhov chaw kom pom cov qhov tsis zoo xws li cov pob dawb, cov resin voids, lossis cov resin pooling. Kev tshuaj xyuas sab hauv feem ntau siv kev kuaj ultrasonic lossis X-ray tsis ua puas tsuaj, uas tuaj yeem qhia ntau hom kev tsis zoo raws li qhov ceev ntawm cov khoom siv thiab ntes cov qhov tsis zoo sab hauv lossis delamination.

Kev Ua Tom Qab

Kev ua tiav tom qab yog qhov tsim nyog vim tias cov khoom siv carbon fiber feem ntau muaj cov burrs lossis flash. Cov no tuaj yeem tshem tawm siv cov tshuab polishing lossis milling cutters kom ua tau raws li cov qauv tsim.

Dhau li ntawm cov kauj ruam txheem no, qee cov khoom sib xyaw ua ke xav tau kev txhaj tshuaj autoclave theem ob rau kev sib koom ua ke lossis kev kho kom zoo, ua rau muaj peev xwm tsim cov khoom sib xyaw ua ke uas muaj cov duab sib txawv.
