Kev siv cov ntaub iav fiber ntau hauv RTM thiab cov txheej txheem nqus tsev vacuum

Cov ntaub sib xyaw ua los ntawm cov iav fiberyog siv dav hauv RTM (Resin Transfer Molding) thiab cov txheej txheem nqus tsev, feem ntau yog hauv cov hauv qab no:

1. Kev siv cov iav fiber ntau hauv cov txheej txheem RTM
Cov txheej txheem RTM yog ib txoj kev molding uascov roj hmabraug txhaj rau hauv lub pwm kaw, thiab cov fiber preform raug impregnated thiab solidified los ntawm resin flow. Raws li cov khoom siv reinforcing, cov iav fiber composite fabrics ua lub luag haujlwm tseem ceeb hauv RTM txheej txheem.

1. (1) Cov nyhuv txhawb zog: Cov ntaub iav fiber sib xyaw ua ke tuaj yeem txhim kho cov khoom siv kho tshuab ntawm RTM molded qhov chaw, xws li lub zog tensile, lub zog khoov thiab kev tawv, vim lawv lub zog siab thiab cov yam ntxwv modulus siab.
2. (2) Hloov kho rau cov qauv nyuaj: Cov txheej txheem RTM tuaj yeem tsim cov khoom nrog cov duab thiab cov qauv nyuaj. Qhov yooj ywm thiab tsim tau ntawm cov ntaub iav fiber ua rau nws hloov kho tau raws li qhov xav tau ntawm cov qauv nyuaj no.
3. (3) Kev tswj tus nqi: Piv nrog rau lwm cov txheej txheem molding composite, cov txheej txheem RTM ua ke nrog cov iav fiber composite fabrics tuaj yeem txo cov nqi tsim khoom thaum ua kom ntseeg tau tias muaj kev ua tau zoo, thiab tsim nyog rau kev tsim khoom loj.

2. Daim ntawv thov ntawm cov iav fiber composite ntaub hauv cov txheej txheem nqus tsev vacuum
Cov txheej txheem nqus tsev infusion (suav nrog VARIM, thiab lwm yam) yog ib txoj kev ntawm impregnating lubntaub fibercov khoom siv txhawb nqa hauv qhov pwm kaw hauv qab lub tshuab nqus tsev tsis zoo los ntawm kev siv cov dej ntws thiab nkag mus ntawmcov roj hmab, thiab tom qab ntawd kho thiab molding. Cov ntaub fiber ntau sib xyaw kuj siv dav hauv cov txheej txheem no.

• (1) Cov nyhuv impregnation: Nyob rau hauv lub tshuab nqus tsev tsis zoo, cov resin tuaj yeem impregnate cov iav fiber composite ntaub, txo cov qhov sib txawv thiab qhov tsis zoo, thiab txhim kho kev ua tau zoo ntawm cov khoom.
• (2) Hloov kho rau cov khoom loj thiab cov khoom loj: Cov txheej txheem nqus tsev muaj tsawg dua qhov kev txwv rau qhov loj thiab cov duab ntawm cov khoom, thiab tuaj yeem siv rau kev txhaj tshuaj ntawm cov khoom loj thiab cov khoom loj, xws li cov hniav cua turbine, hulls, thiab lwm yam. Cov ntaub fiber ntau ua los ntawm iav, ua cov khoom siv txhawb nqa, tuaj yeem ua tau raws li qhov xav tau ntawm lub zog thiab kev tawv ntawm cov khoom no.
• (3) Kev tiv thaiv ib puag ncig: Raws li kev siv tshuab pwm kaw, thaum lub sijhawmcov roj hmabCov txheej txheem infusion thiab kho ntawm cov txheej txheem nqus tsev infusion, cov tshuaj volatile thiab cov pa phem pa phem raug txwv rau hauv lub hnab nqus tsev zaj duab xis, uas muaj kev cuam tshuam me ntsis rau ib puag ncig. Ua cov khoom siv reinforcing tsis muaj kuab paug, cov iav fiber composite ntxiv txhim kho kev tiv thaiv ib puag ncig ntawm cov txheej txheem.

3. Cov piv txwv tshwj xeeb rau daim ntawv thov

• (1) Hauv kev ua haujlwm aerospace, cov ntaub iav fiber sib xyaw ua ke nrog RTM thiab cov txheej txheem nqus tsev tuaj yeem siv los tsim cov dav hlau ntsug tus tw, tis sab nraud thiab lwm yam khoom.
• (2) Hauv kev lag luam tsim nkoj, cov ntaub iav fiber sib xyaw ua ke tuaj yeem siv los tsim cov hulls, decks thiab lwm yam khoom siv.
• (3) Hauv thaj chaw fais fab cua, cov ntaub iav fiber sib xyaw ua ke yog siv los ua cov ntaub ntawv txhawb nqa thiab ua ke nrog cov txheej txheem nqus tsev kom tsim cov hniav cua loj.

Xaus lus
Cov ntaub iav fiber sib xyaw muaj cov kev siv dav dav thiab muaj txiaj ntsig zoo hauv RTM thiab cov txheej txheem nqus tsev. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev ua kom zoo dua ntawm cov txheej txheem, kev siv cov ntaub iav fiber sib xyaw hauv ob qho txheej txheem no yuav dav dua thiab tob dua.
