Dab tsi yog ntab fiber ntau?
Dab tsi yog ntab fiber ntau hauv kev txhaj tshuaj molding?
Floating fiber kuj hu ua exposed fiber. Nyob rau hauv zus tau tej cov elongated iav fiber ntau / ntev carbon fiber raw cov ntaub ntawv yog feem ntau yuav tshwm sim yog cov nto ntawm qhov phem, feem ntau yog rau burnt, raug fiber ntau thiab cov ntaub ntawv paj. Thiab qhov no yog qhov tseem ceeb tshaj plaws, qhov nyuaj tshaj plaws los daws tau yog qhov nthuav tawm fiber ntau. Lub thiaj li hu ua exposed fiber ntau yog cov iav fiber ntau raug rau saum npoo ntawm cov khoom, kuj ntxhib, qhov tsos yog nyuaj rau txais. Dawb iav fiber ntau nyob rau hauv cov yas yaj pwm khiav txheej txheem raug rau sab nrauv, yuav tsum condensed tom qab molding nyob rau hauv cov yas nto los ua ib tug radial dawb kab, thaum cov yas qhov chaw rau cov dub yuav yog vim qhov nce ntawm cov xim sib txawv thiab ntau dua. pom tseeb.
Ua rau ntab fiber ntau hauv LFT khoom
------
1.Nyob rau hauv cov txheej txheem yas yaj, vim yog cov iav fiber ntau thiab cov resin txav txav sib txawv, thiab qhov sib txawv ntawm qhov sib txawv, yog li ob qho tib si muaj kev sib cais, qhov ntom ntawm cov iav fiber ntau ntab rau saum npoo, qhov ntom ntawm cov resin sinks mus rau hauv lub puab, yog li tsim cov iav fiber ntau tshwm sim;
2. iav fiber ntau thiab nylon compatibility yog pluag, vim cov yas yaj nyob rau hauv cov txheej txheem ntws los ntawm cov ntsia hlau, nozzle, khiav thiab rooj vag kev sib txhuam shear nyhuv, yuav ua rau lub zos viscosity sib txawv, tib lub sij hawm nws yuav ua puas lub iav fiber nto interface. txheej, qhov me me ntawm cov viscosity ntawm cov yaj, qhov loj dua cov txheej txheem kev sib tshuam raug puas tsuaj, qhov loj dua ntawm cov iav fiber ntau thiab cov resin kuj tseem me me, thaum lub zog sib txuas me me. mus rau ib qho twg, cov iav fiber ntau yuav tshem tawm ntawm cov resin matrix Thaum lub zog sib txuas me me rau qee qhov, cov iav fiber ntau yuav tshem tawm cov resin matrix thiab maj mam sib sau rau saum npoo thiab raug.
3.Vim cov yas yaj hauv cov txheej txheem ntws los ntawm cov ntsia hlau, lub taub hau, cov neeg khiav dej num thiab lub rooj vag sib txhuam shear quab yuam, yuav ua rau cov viscosity hauv zos sib txawv, thiab tib lub sij hawm yuav ua rau cov iav fiber ntau nto interface txheej, me me yaj viscosity, Qhov loj dua qhov kev puas tsuaj rau cov txheej txheem sib txuas, qhov loj dua ntawm daim ntawv cog lus ntawm iav fiber ntau thiab cov resin tseem me dua, thaum daim ntawv cog lus me me rau qee qhov, cov iav fiber ntau yuav tshem tawm cov kev sib txuas ntawm cov resin matrix, thiab maj mam mus rau saum npoo ntawm cov cumulative thiab nthuav tawm.
4. yas yaj txhaj tshuaj kab noj hniav, yuav tsim ib tug "kwv dej" nyhuv, uas yog, lub iav fiber yuav ntws los ntawm sab hauv mus rau sab nraud, nyob rau hauv kev sib cuag nrog lub nto ntawm kab noj hniav, vim qhov kub ntawm cov pwm nto, lub Qhov zoo ntawm lub teeb condensation ntawm iav fibers yog tam sim ntawd khov, yog hais tias tsis nyob rau hauv lub sij hawm yuav tsum tau tag nrho surrounded los ntawm yaj yuav raug nthuav tawm thiab tsim ntawm "floating fiber!".
Yog li ntawd, qhov tsim ntawm "floating fiber" tshwm sim, tsis tsuas yog nrog cov muaj pes tsawg leeg thiab cov khoom ntawm cov ntaub ntawv yas, tab sis kuj nrog cov txheej txheem molding.
