Kev kawm txog cov ntsiab cai tseem ceeb ntawm kev kho cov khoom sib xyaw ua ke pab ua kom lub neej ua haujlwm ntev dua thiab txo cov nqi hloov pauv. Txawm li cas los xij, txhawm rau kom ua tiav kev kho cov khoom sib xyaw ua ke zoo, yuav tsum ua raws li cov txheej txheem nruj. Yog li ntawd, koj yuav tsum ua raws li 3 lub hauv paus ntsiab lus kom rov qab kho qhov zoo ntawm cov laminate. Tsab xov xwm no yuav muab kev tshuaj xyuas ntxaws ntxaws ntawm 3 lub hauv paus ntsiab lus tseem ceeb no thiab lawv cov kev siv tau.
Txoj Cai 1: Nkag Siab Txog Kev Sib Txuas Lus Qib Ib thiab Qib Ob
Ua ntej, koj yuav tsum paub tias kev kho cov qauv tsev sib txawv ntawm cov txheej txheem tsim khoom thawj zaug. Thaum lub sijhawm tsim khoom, cov resin kho kom zoo los ua ib qho kev sib txuas thawj zaug. Qhov kev sib txuas tshuaj lom neeg thiab lub cev no sib xyaw cov ntaub fiber reinforcing nrog cov resin, tsim kom muaj cov qauv monolithic ruaj khov.
Qhov sib txawv, txhua qhov kev kho vaj tse vam khom kev sib txuas thib ob. Hauv qhov no, daim ntawv kho tsuas yog vam khom kev sib txuas ntawm lub cev rau ntawm qhov chaw ntawm cov qauv kho thawj zaug. Yog li ntawd, lub zog ntawm kev kho sib xyaw yuav nyob ntawm qhov kev ua tau zoo ntawm kev sib txuas ntawm cov tshuaj kho.
Kev tshawb fawb qhia tau hais tias yuav tsum xaiv cov resins uas muaj kev sib txuas zoo dua. Piv txwv li, lub zog nplaum ntawm epoxy resin siab dua li cov polyester resin txheem. Yog li ntawd, epoxy resin yog qhov kev xaiv zoo tshaj plaws rau kev kho cov qauv ua haujlwm siab.
Txoj Cai 2: Ua Kom Thaj Chaw Nto Ntau Dua Rau Kev Kho Kom Zoo Dua
Lub hauv paus ntsiab lus thib ob tsom mus rau qhov kev kho qhov geometric. Vim tias kev sib txuas thib ob vam khom rau qhov kev sib txuas ntawm qhov chaw, kev nce thaj chaw sib txuas ncaj qha ua rau muaj zog ntawm kev sib txuas tag nrho. Yog li ntawd, koj yuav tsum ua tib zoo npaj qhov sib txuas los ntawm kev xuab zeb kom raug.
Kev Xuab Zeb Plab vs. Kev Xuab Zeb Kauj Ruam
Feem ntau, cov kws kho tshuab siv ob txoj hauv kev tseem ceeb los ua kom thaj chaw sib txuas ntxiv: kev xuab zeb phuam thiab kev xuab zeb kauj ruam.
Kev xuab zeb ua los ntawm daim ntaub phuam qhwv caj dab ua rau maj mam taper los ntawm kev tshem tawm cov khoom ntawm lub kaum sab xis tswj tau. Feem ntau, koj yuav tsum tswj qhov sib piv ntawm 20: 1 thiab 100: 1. Rau cov laminates nyias dua, koj tuaj yeem siv lub tshuab xuab zeb ceev ceev nrog cov khoom tshwj xeebroloc sanding discskom ua tiav kev hloov pauv du dua ntawm cov plies qub thiab cov tshiab.
Qhov sib txawv, kev xuab zeb kauj ruam tshem tawm cov khoom siv hauv ntau txheej txheem. Txawm hais tias txoj kev no muab kev pom tseeb dua ntawm kev taw qhia fiber, nws xav tau qhov tseeb siab heev. Yog tias qhov txiav tob dhau, nws tuaj yeem ua rau cov txheej tsis puas tsuaj hauv qab thaj chaw kho. Yog li ntawd, feem ntau cov kws tshaj lij pom zoo kom siv cov xuab zeb scarp rau kev kho cov khoom sib xyaw.
Cov lus sib piv hauv qab no tuaj yeem pab koj xaiv txoj kev xuab zeb kom haum:
| Cov Qauv Ntsuas | Kev Xuab Zeb Pam | Kev Xuab Zeb Kauj Ruam |
|---|---|---|
| Cov txiaj ntsig tseem ceeb | Kev hloov pauv khoom du dua, kev ua haujlwm yooj yim dua | Pom kev zoo ntawm kev taw qhia fiber ntau |
| Qhov nyuaj | Nruab Nrab | Siab heev (kev pheej hmoo ntawm kev txiav cov plies hauv qab) |
| Cov piv/qhov ntev sib xws | 20: 1 txog 100: 1 piv ntawm cov duab | Kauj ruam 0.5-nti ntawm txhua txheej |
| Zoo tshaj plaws rau | Cov laminates nyias nyias, cov khoom tseem ceeb ntawm cov qauv | Cov qauv sib xyaw ua ke hnyav, ntau txheej |
Txoj Cai 3: Sib phim cov qauv laminate qub
Lub hauv paus ntsiab lus thib peb hais tias koj qhov kev kho yuav tsum rov ua dua cov yam ntxwv ntawm cov khoom qub. Tshwj xeeb, koj yuav tsum xyuas kom meej tias thaj chaw kho kom zoo ib yam li qhov tuab, qhov ceev, thiab kev taw qhia ntawm cov fiber ntawm cov laminate qub.
Vim Li Cas Kev Sib Piv Qhov Thickness thiab Ply Orientation Tseem Ceeb
Yog tias qhov chaw kho ntawd tuab dhau, qhov seem ntawd yuav tawv dhau, ua rau muaj kev ntxhov siab ntau thaum lub sijhawm ua haujlwm. Cov kev ntxhov siab no tuaj yeem ua rau kev puas tsuaj ntawm lub cev thiab kev puas tsuaj ntawm cov qauv. Yuav kom tsis txhob muaj qhov no, koj yuav tsum hloov txhua txheej uas raug tshem tawm nrog cov khoom siv tib yam thiab xyuas kom meej tias cov ntaub hloov pauv tau muab tso rau hauv qhov kev taw qhia qub. Txoj kev hloov txheej rau txheej no ua kom ntseeg tau tias cov qauv kho tuaj yeem tiv taus cov qauv tsim.
Tej Yam Uas Feem Ntau Ua Thaum Siv Cov Ntsiab Cai No
Txawm tias koj twb paub txog 3 lub hauv paus ntsiab lus tseem ceeb no lawm los, tej zaum koj tseem yuav ntsib teeb meem thaum lub sijhawm siv. Yog li ntawd, ua ntej pib koj qhov project kho cov khoom sib xyaw tom ntej, rov xyuas cov teeb meem hauv qab no:
