Muaj pes tsawg txheej ntawm cov ntaub pua plag txiav? Qhov hnyav-rau-tuab, nrog cov lej tiag tiag
Nug tsib tus neeg muag khoom seb koj xav tau pes tsawg txheej ntawm cov lev txiav rau 3 hli laminate thiab koj yuav tau txais tsib cov lus teb sib txawv. Qhov ntawd tsis yog vim leej twg yuam kev - nws yog vim cov lus nug zais ib lo lus nug thib ob: ib txheej tuab npaum li cas? Thiab qhov tuab ntawm ib txheej kho ntawm CSM tsis yog ib qho khoom ruaj khov ntawm daim lev. Nws nyob ntawm seb koj rub nws ntau npaum li cas thiab koj dov nws nyuaj npaum li cas. Cov lej luam tawm rau tib qib 450 g / m², piv txwv li, ntau ntawm kwv yees li 0.9 hli txog li 1.15 hli ib txheej - qhov sib kis ntawm ze li ntawm 30% - tsuas yog vim tias ntau qhov chaw xav tias cov resin-rau-iav sib txawv.
Tsab xov xwm no muab tag nrho daim duab rau koj: dab tsi tswj tau qhov tuab ntawm ib txheej, daim ntawv kwv yees rau cuaj qib qhov hnyav uas siv tau, piv txwv ua haujlwm uas hloov qhov tuab ntawm lub hom phiaj mus ua tus lej ntawm cov txheej, thiab peb kauj ruam los kho cov lej hauv koj lub chaw ua haujlwm kom koj tsis txhob qiv lwm tus neeg cov kev xav.
Vim li cas "Muaj pes tsawg txheej" tsis muaj ib lo lus teb
Daim ntawv qhia tuab zoo li muaj hwj chim vim nws luam tawm cov lej tseeb. Tab sis txhua qhov tuab uas luam tawm ib txheej yog qhov kwv yees uas ua los ntawm ob qho kev xav: qhov feem pua ntawm cov fiber uas tus sau xav tau los ntawm cov txheej txheem, thiab qhov kev sib zog uas tus sau xav tau los ntawm lub tshuab laminator. Hloov ib qho kev xav thiab tib daim lev tsim cov tuab kho sib txawv.
Cov neeg muag khoom uas tshaj tawm cov nqi xam feem ntau hais qhov no qhib siab. Piv txwv li, ib tus neeg muag khoom hauv Tebchaws Europe teev nws cov lej tuab ib txheej ua "cov nqi xam ntawm 15 vol.% fiber content" thiab sau tseg tam sim ntawd tias qhov tuab tiag tiag txawv nrog rau qhov ntau ntawm cov resin, kev ua thiab kev sib zog. Cov chaw ua haujlwm hais cov lej qis dua me ntsis rau tib qib vim tias lawv qhia txog kev coj ua tes, qhov twg dov cov resin ntau dhau thiab cov fiber ntau dua. Ob tus lej tsis yog; lawv teb cov lus nug sib txawv.
Yog li ntawd, daim ntawv siv tau ntawm cov lus nug tsis yog "muaj pes tsawg txheej rau X hli?" tab sis "muaj pes tsawg txheej nyob rau hauv kuv cov resin piv thiab kuv dov?" - uas yog vim li cas tsab xov xwm no xaus nrog txoj kev calibration es tsis yog daim ntawv qhia meej.
Qhov sib txawv ntawm cov kev xav muaj cov txiaj ntsig lag luam, tsis yog tsuas yog cov kev siv tshuab xwb. Yog tias daim ntawv hais nqe yog tsim los ntawm 0.9 hli ply xav thiab hauv pem teb ua tiav 1.15 hli nrog nws cov cwj pwm resin, lub laminate tawm los 0.75 hli oversize ntawm rau-ply tsim - ntxiv iav yuav, ntxiv resin sib xyaw, ntxiv hnyav xa khoom. Qhov yuam kev rov qab yog qhov phem dua: daim ntawv hais nqe xav tias cov ply tuab dua ua rau lub cev tsis zoo, thiab qhov tsis txaus tsuas yog tshwm sim thaum kuaj xyuas zaum kawg, thaum qhov kho pheej yig tshaj plaws yog tag nrho cov ply ntxiv hla tag nrho qhov chaw. Sau qhov tuab ply xav rau hauv daim ntawv hais nqe, nyob ib sab ntawm lub hom phiaj, yog kab lus cog lus pheej yig tshaj plaws uas tus tsim khoom tuaj yeem ntxiv.
Dab Tsi Txiav Txim Siab Qhov Thickness ntawm Ib Txheej
Tom qab kho lawm, qhov tuab ntawm ib daim CSM ply yog los ntawm qhov ntim ntawm txhua yam koj tau muab tso rau hauv: iav ntxiv rau cov roj hmab, nrog rau cua dov tawm. Cov iav fibers muaj qhov ceev ntawm kwv yees li 2.55 g / cm³; cov roj hmab polyester kho nyob ze li ntawm 1.2 g / cm³. Cov ntaub pua plag txiav yog cov khoom siv txhawb nqa uas muaj roj hmab ntau - cov laminates uas muab tso tes feem ntau xaus li ntawm 25-35% iav los ntawm qhov hnyav, qis dua qhov uas cov ntaub woven ua tiav - vim tias cov qauv fiber ntau, cov qauv fiber ntau ntes tau ntau cov roj hmab ntawm cov xov.
Qhov feem pua ntawm cov resin yog qhov sib hloov. Qhov hnyav feem pua thiab qhov ntim feem pua kuj qhia txog zaj dab neeg sib txawv: vim tias iav yog kwv yees li ob npaug ntawm cov resin, lub laminate uas yog 28% iav los ntawm qhov hnyav tsuas yog kwv yees li 15% iav los ntawm qhov ntim. Ob qhov chaw hais tias "15 vol%" thiab "30 wt%" rau tib qib yog li ntawd piav qhia yuav luag tib lub laminate, tsis sib cav sib ceg.
Los ntawm cov qhov ceev no koj tuaj yeem xam qhov kwv yees koj tus kheej. Nrog W qhov hnyav ntawm daim lev hauv g / m² thiab r qhov sib piv ntawm cov roj hmab rau iav (kwv yees li 2.0–2.5 rau kev tso tes rau ntawm daim lev), qhov tuab ntawm cov ply kho hauv millimetres yog kwv yees li:
t ≈ W × (0.39 + 0.83 × r) / 1000
Ob qhov kev kuaj xyuas kev noj qab haus huv piv rau cov lej luam tawm: ntawm r = 2.5, 300 g / m² ua haujlwm tawm mus txog li 0.74 hli - sib xws nrog 0.7–0.77 hli uas cov neeg muag khoom hais rau qib ntawd. Ntawm r = 2.0, 450 g / m² muab txog li 0.93 hli - txoj cai hauv 0.9–1.1 hli ntau yam uas feem ntau hais rau kev tso tes. Cov mis tsis yog tus qauv tshiab; nws yog ib txoj hauv kev pob tshab los saib seb qhov kev xav twg tsim tus lej twg.
Peb txoj kev pab txhawb nqa koj mus rau qhov ntawd:
- 1. Piv txwv ntawm cov khoom siv resin.Kev sib tov uas tshaib plab dua thiab ntub dej thawb r mus rau 2.5 thiab ntxiv cov resin ntshiab tuab.
- 2. Kev dov siab.Ib lub paddle roller uas ua haujlwm zoo yuav ua rau lub ply sib sau ua ke, nias tawm cov voids thiab cov resin ntau dhau, thiab tsaws koj ze rau qhov kawg ntawm qhov ntau.
- 3.Txheej txheem.Kev muab lub hnab nqus tsev thiab kev txhaj tshuaj rau hauv lub raj mis ua rau cov tshuaj sib xyaw ua ke ntau dua - cov lej feem ntau hais txog yog kwv yees li 12% nyias dua li kev tso tes hauv lub tshuab nqus tsev thiab kwv yees li 20% thaum tso tshuaj rau hauv lub raj mis. Xav txog cov feem pua ntawm cov tshuaj no ua cov lus qhia ntawm cov neeg muab khoom, tsis yog cov cai ntawm physics.
Tib qho lej suav rov qab mus rau qhov kev txiav txim ntawm cov khoom siv, uas yog qhov uas kev suav txheej txuag tau lossis raug nqi nyiaj. Thaum teem caij lawm - hais tias peb daim ntawm 450 g / m² hla 40 m² pwm - daim lev kom xaj tsuas yog thaj chaw × daim, ntxiv rau qhov kev tso cai txiav rau cov pwm lub puab. Cov cuab yeej nkhaus nyuaj tuaj yeem siv 15-20% ntau dua li thaj chaw ntawm lub ntsej muag, vim tias cov kev txiav tawm ib puag ncig cov duab kos tob tsis tuaj yeem siv dua; cov vaj huam sib luag tiaj tiaj loj pov tseg tsawg dua. Kev txiav txim los ntawm qhov ntev ntawm yob tawm tsam tus lej ntawd, es tsis yog los ntawm kev kwv yees, yog qhov ua rau lub khw tsim khoom tsis xaus txoj haujlwm nrog ib daim laminate tiav ib nrab thiab tsis muaj yob sib phim ntawm lub txee.
Kwv yees qhov tuab ntawm Ply los ntawm qhov hnyav
Cov ntaub pua plag txiav ua tej daim - qib qhov hnyav ntawm thaj chaw, tsis yog daim ntawv qhia ruaj khov, txiav txim siab seb txhua txheej ntxiv tuab npaum li cas

Nyeem kab 6 hli kom zoo zoo, vim nws muaj qhov sib pauv tseem ceeb ntawm tag nrho cov ncauj lus. Peb txheej ntawm 900 g / m² thiab rau txheej ntawm 450 g / m² muab qhov tuab yuav luag zoo ib yam - thiab qhov hnyav iav yuav luag zoo ib yam. Qhov txawv yog kev ua haujlwm (ib nrab ntawm cov voj voog tso nrog qib hnyav) tawm tsam kev sib sau ua ke (txhua daim nyias nyias dov tawm kom huv si dua, ntes tsawg dua qhov khoob). Ntawm qhov loj, tiaj tus hull seem uas cov sijhawm ua haujlwm tseem ceeb, qib hnyav feem ntau yeej. Ntawm cov pwm nyuaj uas txhua daim yuav tsum drape thiab sib sau ua ke, qib sib dua yeej. Qhov kev xaiv ntawd - tsis yog lej - yog qhov chaw txiav txim siab engineering tiag tiag nyob.
Tsawg dua cov txheej hnyav los yog ntau dua cov txheej sib dua?
Qhov kev lag luam tsim nyog nws tus kheej seem, vim nws cuam tshuam nrog qhov tsis zoo uas ua rau cov ntsuas tuab ntxiv: cua ntes.
"Fake thickness" yog ib qho kev ua tsis tiav tiag tiag.Cov khoob - cov hnab cua me me uas tseem nyob nruab nrab ntawm cov fibers uas cov dej ntub lossis dov tsis tiav - ntxiv qhov tuab uas ntsuas tau tab sis tsis muaj tus nqi ntawm cov qauv. Ib feem tuaj yeem tawm ntawm pwm ntawm qhov tuab tshwj xeeb thiab tseem ua tsis tau zoo, vim tias ntawm daim ntawv cov fibers tsis ua haujlwm raws li qhov tuab qhia. Kev sim pom yog yooj yim thiab tsim nyog cob qhia txhua tus laminator rau: CSM uas ntub kom zoo yuav hloov pauv pob tshab; txhua qhov dawb yog iav qhuav lossis cua uas yuav tsum tau dov tawm ua ntej txheej tom ntej poob qis.
Cov txheej nyias nyias sib sau ua ke zoo dua.Txhua daim iav uas hnyav 300 g/m² muaj cov fiber tsawg dua rau lub log kom ua haujlwm dhau, yog li ntawd, kev tsim ntau daim iav uas muaj kev qhuab qhia feem ntau yuav nyob rau qhov kawg ntawm qhov tuab nrog tsawg dua qhov khoob. Cov qib hnyav ua rau muaj kev pheej hmoo: dov tsawg dua ib daim iav, thiab daim iav uas ntub dua, tuab dua uas yooj yim dua rau kev tshaib plab ntawm qhov sib txuas.
Tab sis cov thickness ua rau cov khoom siv rigidity.Hauv tus qauv khoov-nruj yooj yim, qhov nruj ntsuas nrog lub voos xwmfab ntawm qhov tuab ntawm laminate - ib feem 10% nyias dua li qhov npaj tseg muab kwv yees li 27% ntawm nws qhov kev khoov nruj ntawm tus qauv ntawd. Qhov no yog vim li cas caum lub hom phiaj tuab nrog "ntau cov resin" yog lub ntxiab: cov resin ntxiv ntxiv qhov tuab ntawm lub cev, tab sis cov resin muaj kev ywj pheej ntau dua li iav, yog li qhov nce ntawm qhov nruj yog qhov me me thiab qhov hnyav raug nplua yog qhov tseeb. Qhov tuab yuav tsum los ntawm cov fiber, tsis yog los ntawm pas dej resin.
Thiab ib daim lev uas tsuas yog siv rau hauv pem teb xwb muaj cov kev txwv.Cov lev uas raug txiav yog quasi-isotropic thiab muaj cov resin ntau los ntawm kev tsim - tsuas yog ib feem ntawm nws cov fiber ua haujlwm hauv ib qho kev taw qhia xwb, yog li ntawm qhov hnyav sib npaug nws tsis tuaj yeem sib phim cov ntaub roving rau lub zog taw qhia. Cov lev yog cov cuab yeej zoo rau kev ua kom haum, kev coj tus cwj pwm isotropic thiab cov tawv nqaij kaw, tiv taus tawg; thaum tus qauv tsim xav tau lub zog taw qhia ntawm qhov hnyav tsawg kawg nkaus, cov txheej lev feem ntau yog interleaved nrog cov ntaub roving es tsis txhob sib sau ua ke ib leeg.
Calibrate hauv Peb Kauj Ruam
Tag nrho cov saum toj no yuav muaj txiaj ntsig tiag tiag thaum koj hloov cov kev xav dav dav nrog koj tus kheej qhov ntsuas. Nws siv sijhawm ib tav su:
| Kauj Ruam | Yuav ua li cas | Yuav sau dab tsi |
|---|---|---|
| 1 | Laminate daim coupon me me 2-ply ntawm qib paub (450 g / m² yog qhov yooj yim) nrog koj cov resin tsim tawm, koj li kev dov ib txwm muaj, ntawm koj lub khw kub | Qib, cov txheej txheem resin thiab qhov sib tov sib xyaw, qhov kub thiab txias hauv khw |
| 2 | Tom qab kho tag nrho, ntsuas qhov tuab ntawm 5+ cov ntsiab lus nrog lub caliper lossis micrometer; nruab nrab lawv | Qhov nruab nrab ntawm cov ply thickness, qhov tuab ntawm ib lub ply kho = (tag nrho − peel-ply/nto ntxiv) ÷ 2 |
| 3 | Faib qhov hnyav ntawm daim lev los ntawm koj qhov tuab ntawm daim ply kom tau koj tus kheej qhov hloov pauv; rov suav cov lus saum toj no nrog nws. | Koj qhov sib piv hauv g/m² ib mm, thiab koj qhov piv ntawm cov resin zoo |
Txij thaum ntawd los, cov txheej suav rau cov hom phiaj tuab tshiab siv koj tus lej, tsis yog tus neeg muag khoom li. Yog tias tom qab koj hloov mus rau lub hnab nqus tsev lossis kev txhaj tshuaj, khiav daim coupon dua - qhov kev nias uas cov txheej txheem ntawd siv txhais tau tias cov yam ntxwv ntawm kev tso tes ua rau qhov tuab dhau qhov kwv yees.
Daim coupon los ntawm kauj ruam 1 kuj muaj lub neej thib ob thiab: tuav cov qauv kho kom zoo tiv thaiv lub teeb. Daim coupon uas pom tseeb sib npaug lees paub koj txoj kev ntub dej; thaj chaw huab lossis mis nyuj qhia qhov twg dov xav tau ua haujlwm - tib lub tswv yim tshuaj xyuas koj yuav siv rau ntawm cov khoom tsim khoom.
Kev kho kom raug tsis yog ib zaug xwb. Cov khoom siv resin, qhov kub ntawm lub khw thoob plaws lub caij, thiab txawm tias cov menyuam hnav txhua yam ua rau qhov sib piv ntawm cov resin zoo, yog li rov ua daim coupon thaum twg muaj kev hloov pauv - tus neeg muab khoom siv resin tshiab, kev hloov pauv ntawm lub caij ntuj sov mus rau lub caij ntuj no, cov neeg ua haujlwm tshiab ntawm cov menyuam - ua rau qhov sib piv ncaj ncees. Cov khw muag khoom uas sau txhua daim coupon qhov sib piv nrog hnub tim thiab cov khoom siv resin tsim cov ntaub ntawv me me uas tig cov kev tsis sib haum xeeb nrog cov neeg siv khoom mus rau hauv kev tshawb nrhiav tsib feeb es tsis yog kev sib cav. Tus cwj pwm no raug nqi ib hnub tav su ib lub caij thiab maj mam lees paub txhua qhov kev cog lus ntawm cov tuab ntawm phau ntawv xaj.
Cov Lus Nug Feem Ntau
Ib txheej ntawm 450 gsm chopped strand lev tuab npaum li cas?
Kwv yees li ntawm 0.9–1.1 hli hauv tes tso, nrog cov resin: iav ntawm 2: 1 thiab 2.5: 1. Cov nqi xam tau luam tawm ntawm cov feem fiber tsawg dua khiav siab dua me ntsis, ze li ntawm 1.15 hli. Cov lus teb ncaj ncees yog qhov ntau thiab tsawg, tsis yog ib qho taw tes: ntsuas ib daim coupon kho ntawm koj tus kheej kab thiab koj yuav muaj tus lej zoo dua li daim ntawv qhia.
Kuv puas tuaj yeem tsim tag nrho kuv cov tuab nrog lev ib leeg xwb?
Koj ua tau, thiab rau cov khoom isotropic, nkhaus lossis cov khoom tseem ceeb rau daim tawv nqaij koj feem ntau yuav tsum tau ua. Tus nqi yog qhov hnyav: cov lev laminates nqa ob mus rau ob thiab ib nrab npaug ntawm lawv qhov hnyav iav hauv cov resin, yog li ib feem ntawm lev-tsuas yog hnyav dua thiab tsis tawv dua li cov laminate uas muaj tib lub tuab. Rau cov seem ntawm cov qauv uas qhov tawv ib kilo tseem ceeb, interleave lev nrog woven roving es tsis txhob stacking lev ib leeg.
Puas yog ib daim laminate uas muaj cov resin ntau txhais tau tias yog ib daim laminate uas tsis muaj zog?
Tsis yog cia li - nws txhais tau tias muaj qhov sib npaug sib txawv. Iav muab lub zog; cov roj hmab puv, kaw thiab khi cov khaubncaws sab nraud povtseg. Cov lev laminates yog cov roj hmab nplua nuj vim tias lawv cov qauv random, bulky xav tau cov roj hmab los qhwv txhua txoj hlua, thiab hauv kev pauv lawv ua raws li cov pwm nyuaj, tiv taus kev luam tawm thiab ua kev kho kom zam txim. Hom kev ua tsis tiav uas yuav tsum zam tsis yog "nplua nuj" tab sis "voided": cov hnab cua yog qhov ua rau lub laminate tsis muaj zog, uas yog vim li cas kev qhuab qhia dov tseem ceeb dua li qhov piv ntawm cov roj hmab nws tus kheej.
Xaiv Cov Qib, Tom Qab ntawd Ua Pov Thawj Rau Ntawm Koj Lub Pwm
Ib qho kev coj ua kawg uas tsim nyog ua: thaum twg daim duab hloov pauv - qhov tuab ntawm daim ntawv lo hloov kho, daim laminate hloov mus rau lwm cov resin - rov ua qhov kev kwv yees ua ntej kev txiav txim siab cov khoom siv, tsis yog tom qab. Cov txheej suav pheej yig rau kev suav dua thiab kim heev rau kev nrhiav pom qhov tsis raug ntawm kev teeb tsa nruab nrab.
