Yuav ua li cas rau cov duab ntev fiber reinforced thermoplastics?

2. Qhov chaw thiab pwm tsim
Cov khoom zoo thiab pwm tsim kuj tseem muaj txiaj ntsig zoo rau kev tuav cov fiber ntau ntev LFRT.Kev tshem tawm cov kaum ntse ntse nyob ib ncig ntawm qee cov npoo (xws li tav, tus thawj coj, thiab lwm yam nta) tuaj yeem zam kev ntxhov siab tsis tsim nyog hauv qhov molded thiab txo cov fiber ntau hnav.
Cov khoom yuav tsum tau txais kev tsim cov phab ntsa nominal nrog cov phab ntsa tuab.Kev hloov pauv loj hauv phab ntsa tuab tuaj yeem ua rau tsis sib xws thiab tsis xav tau fiber ntau orientation hauv ib feem.Qhov twg nws yuav tsum yog thicker lossis thinner, tam sim ntawd hloov ntawm phab ntsa thickness yuav tsum tau zam kom tsis txhob tsim ntawm high-shear cheeb tsam uas yuav ua rau cov fibers puas thiab ua qhov chaw ntawm kev nyuaj siab concentration.Feem ntau sim qhib lub rooj vag hauv cov phab ntsa tuab thiab ntws mus rau qhov nyias nyias, ua kom lub filling kawg ntawm qhov nyias nyias.
Lub hauv paus ntsiab lus zoo ntawm cov yas tsim tau qhia tias ua kom cov phab ntsa tuab hauv qab 4 hli (0.160in) yuav txhawb nqa qhov zoo thiab zoo sib xws thiab txo qhov muaj peev xwm ntawm dents thiab voids.Rau LFRT composites, qhov zoo tshaj plaws phab ntsa thickness feem ntau yog hais txog 3 hli (0.120in), thiab qhov tsawg tshaj plaws thickness yog 2 hli (0.080in).Thaum cov phab ntsa tuab tsawg dua 2 hli, qhov tshwm sim ntawm fiber ntau tawg tom qab cov khoom nkag mus rau hauv pwm nce.
Ib feem tsuas yog ib qho ntawm cov qauv tsim, thiab nws tseem ceeb heev uas yuav tsum xav txog seb cov khoom nkag mus rau hauv pwm li cas.Thaum cov neeg khiav dej num thiab cov rooj vag coj cov khoom siv rau hauv cov kab noj hniav, yog tias tsis muaj qhov tsim nyog, kev puas tsuaj fiber ntau yuav tshwm sim hauv cov cheeb tsam no.
Thaum tsim cov pwm rau kev tsim cov LFRT cov khoom sib xyaw, ib qho kev sib tw khiav yog qhov zoo tshaj plaws, thiab nws txoj kab uas hla yam tsawg kawg nkaus yog 5.5mm (0.250in).Tsuas yog cov neeg khiav dej num puv puv, lwm hom kev sib tw yuav muaj cov kab ntse, uas yuav ua rau muaj kev ntxhov siab thaum lub sij hawm molding txheej txheem thiab rhuav tshem cov nyhuv ntawm cov iav fiber ntau.Kub khiav tshuab nrog qhib khiav yog tau.
Qhov tsawg kawg nkaus thickness ntawm lub rooj vag yuav tsum yog 2 hli (0.080in).Yog tias ua tau, nrhiav lub rooj vag raws ntug uas tsis cuam tshuam cov khoom ntws mus rau hauv kab noj hniav.Lub rooj vag ntawm qhov chaw yuav tsum tau tig los ntawm 90 ° los tiv thaiv fiber ntau tawg thiab txo cov khoom siv kho tshuab.
Thaum kawg, xyuam xim rau qhov chaw ntawm txoj kab fusion thiab paub tias lawv cuam tshuam li cas rau thaj chaw uas cov khoom siv raug thauj khoom (los yog kev ntxhov siab) thaum siv.Txoj kab fusion yuav tsum tau tsiv mus rau thaj chaw uas qhov kev ntxhov siab yuav tsum qis dua los ntawm qhov tsim nyog ntawm lub rooj vag.
Kev tshuaj xyuas lub tshuab mould filling tuaj yeem pab txiav txim siab qhov twg cov kab no yuav nyob.Cov qauv finite element tsom xam (FEA) tuaj yeem siv los sib piv qhov chaw ntawm kev ntxhov siab nrog qhov chaw ntawm cov kab sib txuas tau txiav txim siab hauv cov pwm filling tsom xam.
Nws yuav tsum raug sau tseg tias cov khoom thiab cov pwm tsim no tsuas yog cov lus qhia.Muaj ntau yam piv txwv ntawm cov phab ntsa nyias nyias, nyias phab ntsa thicknesses, thiab ilv los yog zoo nta.Kev ua tau zoo yog tiav los ntawm kev siv LFRT compounds.Txawm li cas los xij, qhov ntxiv koj deviate los ntawm cov lus pom zoo no, ntau lub sij hawm thiab kev siv zog nws yuav siv sij hawm los xyuas kom meej tias tag nrho cov txiaj ntsig ntawm kev siv tshuab fiber ntau tau pom ntev.
