Ua tib zoo saib ntawm ntu ntawm carbon fiber lossis fiberglass raj lossis phaj thiab koj yuav pom tias cov fibers mus rau qhov sib txawv, cov lus qhia tshwj xeeb. Sib piv cov qauv sib txawv ntawm cov tubing koj yuav pom tias cov kev taw qhia fiber ntau, tseem hu ua kev taw qhia, tsis yog ib txwm zoo ib yam. Composite tube thiab phaj manufacturers siv cov kev taw qhia sib txawv nyob ntawm seb lawv xav ua kom tiav nrog cov khoom tiav.
Hauv tsab xov xwm no, peb yuav piav qhia txog yuav ua li cas cov kev taw qhia fiber ntau cuam tshuam cov khoom ntawm carbon fiber thiab fiberglass tubing. Cov khoom tshwj xeeb feem ntau zoo tagnrho rau cov ntawv thov tshwj xeeb. Thaum kawg ntawm cov ntawv tshaj tawm no koj yuav paub tias fiber ntau orientation cuam tshuam rau lub raj li cas thiab yuav ua li cas xaiv qhov kev taw qhia fiber ntau rau koj qhov project.
SAUM 3 FIBER ORIENTATIONS
Fibers tuaj yeem taw qhia nyob rau hauv ib qho kev taw qhia ntawm 0℃thiab 180 degree, txawm hais tias fiber ntau orientation tshaj 90℃feem ntau hu ua lub kaum sab xis tsis zoo. Piv txwv li, 135℃fiber ntau lub kaum sab xis yog sib npaug rau -45℃kaum. Feem ntau cov pa roj carbon fiber ntau thiab fiberglass tubing nyob rau hauv kev ua lag luam niaj hnub no siv ob los yog ntau tshaj ntawm cov kev taw qhia no:
0℃- Zero-degree fiber ntau lub kaum sab xis yog qhov feem ntau siv kev taw qhia. Thaum cov fibers yog taw qhia nyob rau hauv cov kev taw qhia ntawm lub load lawv yog cov muaj zog thiab stiffest. Ntawm tubing, xoom-degree kev taw qhia yog nyob ntawm qhov ntev ntawm lub raj thiab pab txhawb kev khoov lub zog.
90℃- cuaj caum-degree fiber ntau yog siv thaum khoov ob qho kev qhia yuav tsum tau ua. Hauv ib lub raj cua cuaj caum-degree fibers yog taw qhia nyob rau hauv lub voj voog ntawm lub raj. Lawv pab kom lub raj ntawm crushing los yog buckling thaum loaded.
± 45℃- Plaub caug-tsib-degree kaum feem ntau yog siv nrog xoom thiab cuaj caum-degree plies los tsim ib qho quasi-isotropic layup. Ib qho zoo plaub caug-tsib-degree txheej yog yuav luag ib txwm ua ke nyob ib sab ntawm qhov tsis zoo plaub caug-tsib-degree txheej. Thaum siv rau ntawm lub raj, plaub caug-tsib-degree txheej pab txhawb kev sib tw thiab lub zog.
Woven fiber ntau feem ntau hu ua muaj 0/90℃fiber ntau lub kaum ntse ntse vim muaj fibers nyob rau hauv ob qho tib si cov lus qhia, tab sis nyob rau hauv ib daim. Qee cov ntaub ntawv woven tuaj yeem muaj ntau cov lus qhia fiber ntau; Piv txwv li, triaxial weaves muaj fiber ntau hauv peb cov lus qhia thiab feem ntau yog quasi -isotropic los ntawm lawv tus kheej.
FIBER ORIENTATION 'Seffect ntawm PROPERTIES
Txoj kev fibers yog taw qhia hauv carbon fiber lossis fiberglass layup cuam tshuam nws cov khoom ua txhua yam los ntawm cov raj mus rau qhov chaw - nkoj. Cov neeg tsim khoom yuav tsum xav txog cov khoom no thaum lawv tsim cov txheej txheem. Hauv qab no peb yuav piav qhia yuav ua li cas txhua qhov kev taw qhia fiber ntau cuam tshuam rau cov khoom.
1. 0℃ORIENTATION
Yog hais tias ib feem yuav tsuas yog loaded nyob rau hauv ib txoj kev nws yog zoo tagnrho kom muaj tag nrho cov fibers oriented nyob rau hauv cov kev taw qhia. Pultruded pas nrig thiab tubing yog cov piv txwv ntawm ib feem uas tsuas muaj 0℃fibers. Txij li feem ntau qhov chaw tsis thauj khoom hauv ib qho kev taw qhia xwb peb yuav tsum tau ntxiv lwm cov ces kaum kom ua kom muaj zog. Ib lub raj uas pom tsuas yog khoov thiab tsis muaj kev sib tw yuav tseem yuav tau txais txiaj ntsig los ntawm qee qhov ntxiv fiber ntau. Ntxiv 90℃cov khaubncaws sab nraud povtseg pab lub raj tuav nws cov duab zoo dua kom nws tsis txhob buckle ntxov.
2. 90℃ORIENTATION
Raws li tau hais dhau los, 90℃txheej feem ntau ntxiv rau cov raj kom lawv tiv taus ntau dua rau buckling thiab crushing. High concentrations ntawm 90℃los yog "hoop" khaubncaws sab nraud povtseg kuj muaj nyob rau hauv lub siab hlab ntsha. Txij li thaum lub zog ua kom lub raj loj hauv lub nkoj siab, 90℃txheej tiv thaiv lub zog zoo tshaj plaws. Thaum 90℃cov khaubncaws sab nraud povtseg siv ua ke nrog 0℃txheej hauv lub phaj, nws hu ua bidirectional. Siv cov ntaub qhwv tuaj yeem yog txoj hauv kev yooj yim los tsim cov khoom siv fiber ntau hauv 0℃thiab 90℃cov lus qhia.
3. ± 45℃ORIENTATION
45℃cov khaubncaws sab nraud povtseg ua haujlwm sib txawv nyob ntawm daim ntawv thov. Koj yuav luag ib txwm pom +45℃ua ke nyob ib sab ntawm -45℃txheej. Qhov no yog ua kom lub laminate "sib npaug" thiab los ntawm kev sib tw quab yuam thaum thauj khoom. Thaum 45℃txheej yog siv nyob rau hauv ib lub phaj uas twb muaj ib tug sib npaug zos mix ntawm 0℃thiab 90℃khaubncaws sab nraud povtseg lub phaj yuav quasi -isotropic. Whereas ib phaj bidirectional muaj vaj huam sib luag nyob rau hauv ob txoj kev, ib tug quasi-isotropic phaj muaj quasi{16}} sib npaug zog nyob rau hauv txhua txoj kev. Hauv ib lub raj, 45℃cov khaubncaws sab nraud povtseg ua haujlwm ntawm kev ntxiv lub zog torsional thiab nruj. Tias yog vim li cas thaum lub raj yog twisted, lub zog ua ntawm lub laminate yog tiag tiag ntawm plaub caug - tsib-degrees. Qee lub laminates yuav siv lub kaum sab xis dua li 45℃raws li kev cuam tshuam ntawm kev khoov, crushing thiab torsion kev ua tau zoo. Txij li thaum 0℃txheej tsis tuaj yeem ua rau ntawm cov hlab ntsws filament nws yog qhov pom 10℃lossis 15℃cov khaubncaws sab nraud povtseg siv.
TXOJ CAI NTAWM KEV PAB CUAM TSHIAB
Tam sim no koj paub tias txhua qhov kev taw qhia fiber ntau cuam tshuam li cas, koj tuaj yeem xaiv txoj cai layup. Yog tias koj xav tau ib lub raj uas ua tau zoo nyob rau hauv ntau yam kev mob, kev teeb tsa bidirectional yog qhov zoo tagnrho. Yog tias koj xav tau lub raj uas ua tau zoo hauv kev sib tw, xaiv cov khoom uas muaj ntau tshaj 45℃txheej. Yog tias koj xav tau kom nce thickness sai, cov khoom siv woven tej zaum yuav yog ib qho kev xaiv zoo.
Xinbo Composite muab cov phaj thiab cov raj nrog layups kom tau raws li yuav luag txhua qhov kev thov.
