Kev Taw Qhia: Cov Kev Cov nyom uas pheej muaj ntawm PA/GF Cov Khoom Siv

Cov iav fiber reinforced polyamides (PA/GF) yog lub hauv paus tseem ceeb hauv kev tsim khoom niaj hnub no vim lawv lub zog tshwj xeeb, tiv taus cua sov, thiab ruaj khov. Txij li cov khoom siv hauv tsheb thiab cov khoom siv hluav taws xob rau cov neeg siv khoom mus rau cov qauv aerospace thiab cov tshuab kev lag luam, cov ntaub ntawv PA/GF siv dav hauv cov ntawv thov kev ua haujlwm siab uas xav tau kev ruaj khov, kev ua haujlwm raug, thiab kev ntseeg tau.

Txawm hais tias muaj cov txiaj ntsig no los xij, cov ntaub ntawv PA/GF muaj cov teeb meem uas yuav ua rau kev tsim khoom tsis zoo, qhov zoo ntawm cov khoom, thiab kev siv thaum kawg tsis zoo. Cov teeb meem uas feem ntau muaj xws li kev tawg, kev yaj tsis zoo, kev hnav cov cuab yeej, thiab kev raug cov iav fiber (cov fibers ntab). Cov teeb meem no ua rau cov nqi pov tseg nce ntxiv, cov nqi tsim khoom nce ntxiv, thiab xav tau kev ua tiav tom qab ntxiv - cov teeb meem uas feem ntau cuam tshuam rau R&D, kev tsim khoom, thiab cov pab pawg yuav khoom.

Kev nkag siab thiab daws cov teeb meem no yog qhov tseem ceeb rau cov tuam txhab tsim khoom uas tsom mus rau kev ua kom muaj peev xwm ntawm cov ntaub ntawv PA / GF ntau tshaj plaws thaum tswj kev ua haujlwm zoo thiab ua tau raws li cov qauv zoo.

Qhov Mob 1: Kev Ua Haujlwm Nyuaj thiab Nyuaj Rau Kev Tswj Xyuas

Kev puas tsuaj thiab kev hloov pauv

Cov ntaub ntawv PA/GF yog cov anisotropic heev vim yog qhov kev taw qhia ntawm cov iav fibers. Thaum lub sijhawm txias, qhov tsis sib xws shrinkage feem ntau ua rau warpage hauv cov khoom loj lossis geometrically complex. Qhov no ua rau qhov tseeb ntawm qhov ntev, ua rau cov khoom seem thiab rov ua dua, thiab siv sijhawm thiab cov peev txheej. Rau cov lag luam xws li tsheb thiab aerospace, qhov twg kev kam rau siab yog qhov tseem ceeb, txawm tias me me warpage tuaj yeem ua rau cov khoom tsis lees txais.

Cov dej yaj tsis zoo

Qhov ntxiv ntawm cov iav fibers ua rau cov yaj viscosity ntau ntxiv, tsim cov teeb meem flowability thaum lub sijhawm txhaj tshuaj molding. Cov viscosity yaj siab tuaj yeem ua rau:

• Cov duab luv luv

• Cov kab vuam

• Cov teeb meem ntawm qhov chaw

Cov teeb meem no yog qhov teeb meem tshwj xeeb rau cov khoom siv nyias nyias lossis cov khoom uas muaj cov qauv pwm nyuaj. Cov viscosity siab kuj xav tau lub zog txhaj tshuaj ntau dua, ua rau kev siv zog ntau ntxiv thiab kev ntxhov siab rau cov khoom siv pwm.

Kev Siv Cuab Yeej Sai Dua

Cov iav fibers yog abrasive thiab tawv, ua rau cov pwm, cov khiav, thiab cov nozzles hnav sai dua. Hauv kev txhaj tshuaj molding thiab 3D printing, qhov no ua rau lub neej ntawm cov cuab yeej luv dua, nce tus nqi txij nkawm, thiab tuaj yeem txo lub sijhawm tsim khoom. Rau 3D printing, cov filaments uas muaj PA / GF tuaj yeem hnav cov nozzles, cuam tshuam rau ob qho tib si zoo thiab throughput.

Kev Sib Txuas Lus Tsis Txaus (rau Kev Luam Ntawv 3D):

Hauv kev tsim khoom ntxiv, cov PA/GF filaments yuav muaj kev sib txuas tsis zoo ntawm cov khaubncaws sab nraud thaum lub sijhawm luam ntawv. Qhov no ua rau cov khoom siv kho tshuab ntawm cov khoom luam tawm txo qis, ua rau lawv tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog thiab kev ruaj khov.

Qhov Mob 2: Kev Raug Cov Iav Fiber Thiab Nws Qhov Cuam Tshuam

Kev raug cov iav fiber, tseem hu ua "floating fibers," tshwm sim thaum cov fibers tawm ntawm qhov chaw polymer. Qhov xwm txheej no tuaj yeem cuam tshuam tsis zoo rau ob qho tib si aesthetic thiab kev ua tau zoo:

Kev Pom Tsis Zoo:Cov nto zoo li ntxhib, tsis sib npaug, thiab tsaus ntuj. Qhov no tsis raug lees txais rau cov ntawv thov uas xav tau kev saib zoo nkauj, xws li sab hauv tsheb, cov khoom siv hluav taws xob, thiab cov khoom siv rau cov neeg siv khoom.

Kev Xav Tactile Tsis Zoo:Cov chaw ntxhib thiab khawb ua rau cov neeg siv tsis paub siv thiab tsis pom qhov zoo ntawm cov khoom.

Txo Kev Ruaj Khov:Cov fibers uas raug nthuav tawm ua haujlwm ua cov khoom siv rau kev ntxhov siab, txo qhov muaj zog ntawm qhov chaw thiab kev tiv thaiv kev sib txhuam. Hauv cov chaw ib puag ncig hnyav (piv txwv li, av noo lossis tshuaj lom neeg raug), kev raug fiber ntau ua rau cov khoom laus sai dua thiab kev ua haujlwm poob qis.

Cov teeb meem no tiv thaiv cov ntaub ntawv PA / GF kom tsis txhob ncav cuag lawv lub peev xwm tag nrho, yuam cov chaw tsim khoom kom hloov pauv ntawm qhov zoo, kev zoo nkauj, thiab kev ua haujlwm zoo.

Cov Kev Daws Teeb Meem Tshiab rau Cov Teeb Meem Ua PA/GF

Cov kev nce qib tshiab hauv kev tshawb fawb txog cov khoom siv, cov thev naus laus zis ntxiv, thiab kev tsim kho interface muab cov kev daws teeb meem rau cov teeb meem uas tau muaj ntev los no. Los ntawm kev sib xyaw ua ke cov tshuaj PA / GF hloov kho, cov khoom siv silicone, thiab cov khoom siv fiber-matrix sib xws, cov chaw tsim khoom tuaj yeem txo qhov warpage, txhim kho cov dej ntws, thiab txo qhov kev cuam tshuam ntawm cov iav fiber.
