Txoj kev siv tshuab ntawm kev ua haujlwm siab thermoplastic composite yog tsuas yog hloov los ntawm thermosetting resin composite thiab hlau ua thev naus laus zis. Raws li cov khoom siv sib txawv, nws muaj peev xwm muab faib ua molding, ob chav zaj duab xis moulding, autoclave molding, nqus hnab molding, filament winding molding, calendering molding, thiab lwm yam ntawm cov kev no, peb lub tuam txhab (Wuxi Zhishang Tshiab Material Technology Co., Ltd.) siv ntau txoj hauv kev moulding, suav nrog molding, ob chav zaj duab xis moulding, winding moulding, nqus hnab molding thiab autoclave molding.
& nbsp;
（1） Kev ua pwm
Moulding yog txiav cov ntawv prepreg raws li qhov loj me ntawm cov pwm, ua kom sov hauv qhov cub cua sov kom sov siab tshaj qhov cov roj nplaum kub kub, thiab tom qab ntawd xa nws mus rau qhov loj - nplai tuag rau qhov kub kub ceev. Lub voj voog sib tw feem ntau yog ua tiav nyob rau hauv kaum tawm ntawm ob peb feeb mus rau. Hom no muaj kev siv hluav taws xob tsawg thiab tus nqi tsim khoom, thiab khoom tsim tau zoo. Nws yog feem ntau hom tshuaj molding hauv txoj kev molding txheej txheem ntawm cov khoom siv thermoplastic.
& nbsp;
(2) Bimembrane forming
Ob chav membrane sib sau, tseem hu ua resin membrane penetration molding, yog ib txoj kev tsim los ntawm tuam txhab ICI los npaj cov khoom sib txuas ua ke los ntawm kev siv prepreg. Txoj kev no zoo rau kev tsim thiab ua ntawm cov ntu.
& nbsp;
Hauv ob chav zaj duab xis tsim, qhov txiav - tawm prepreg muab tso nruab nrab ntawm ob txheej ntawm deformable saj zawg zog cob zaj duab xis thiab hlau zaj duab xis, thiab lub periphery ntawm zaj duab xis yog ntim nrog hlau lossis lwm yam ntaub ntawv. Thaum lub sij hawm tsim cov txheej txheem, tom qab cua sov mus rau qhov tsim qhov kub thiab txias, qee qhov kev tsim qauv siab raug thov, thiab cov seem yog deformed raws li cov duab ntawm cov hlau pwm, thiab thaum kawg txias thiab zoo li tus. Hauv kev siv ob npaug ntawm cov yeeb yaj kiab tsim, qhov chaw thiab cov yeeb yaj kiab yuav tsum ntim thiab nqus. Vim tias qhov deformability ntawm cov zaj duab xis, qhov kev txwv ntawm cov dej ntws txaus yog nyob deb tsawg tshaj qhov uas muaj cov pwm sib txawv. Ntawm qhov tod tes, vim hais tias cov yeeb yaj kiab deformed nyob rau hauv lub tshuab nqus tsev tuaj yeem tsim kev kub ntxhov ntawm qhov sib txawv, nws tuaj yeem txhim kho lub siab hloov pauv ntawm qhov chaw thiab xyuas kom muaj qhov ua tau zoo.
& nbsp;
(3) Winding forming
Qhov sib txawv ntawm cov ntsiab lus cua ntawm thermoplastic composite thiab thermosetting composite yog tias thaum cua, cov xov paj prepreg (daim kab xev) yuav tsum tau rhaub rau qhov muag qhov taw tes, thiab rhuab ntawm qhov sib tiv tauj ntawm cov tub ntxhais pwm. Cov txheej txheem cua kub nquag yog conduction cua sov, dielectric cua sov, hluav taws xob cua sov, hluav taws xob hluav taws xob cua sov thiab lwm yam. Hauv hluav taws xob hluav taws xob cua sov, hluav taws xob infrared (IR), microwave (MW) thiab xov tooj cua zaus (RF) cua sov tau muab faib vim muaj cov txheej txheem sib txawv los yog nthwv hluav taws xob. Xyoo tsis ntev los no, cov cua sov laser thiab tshuab cua sov ultrasonic tau kuj tau tsim.
Xyoo tsis ntev los no, cov pro hom winding tshuab tau tsim, nrog rau ib - kauj ruam moulding txoj kev, uas yog, cov fiber tau ua rau hauv kev npaj ua ntej (txoj siv) los ntawm thermoplastic cob cov hmoov ua kom lub txaj, thiab tom qab ntawd ncaj qha kev txhab ntawm cov tub ntxhais pwm; lwm txoj kev, uas yog, carbon fiber prepreg (siv) yog cov hluav taws xob ncaj qha, thiab cov roj hmab thermoplastic yog melted los ntawm hluav taws xob thiab cua sov, kom cov xov paj (xov siv) ua rau cov khoom lag luam; thiab Peb yuav tsum siv neeg hlau cov kab hlau los txhim kho qhov raug thiab kev siv tshuab ua kom cov khoom siv winding, yog li nws tau txais kev ua tib zoo saib.
& nbsp;
(4) Pultrusion
Pultrusion yog kev tsim cov txheej txheem txuas tas mus li ntawm cov ntawv sib txuas nrog cov ntu sib txuas ntawm ntu - ntu. Nws tau tsim thaum xub thawj los tsim cov khoom lag luam yooj yim nrog cov khoom siv sib faib fiber ntau - cov khoom siv tiv thaiv cov ntoo khaub lig - ntu, thiab maj mam tsim rau hauv cov khoom lag luam nrog cov khoom khov, cov khoob thiab ntau yam nyuaj ntawm cov khoom hla - ntu. Cov yam ntxwv ntawm cov ntaub ntawv tuaj yeem tsim los ua kom tau raws li kev ua haujlwm ntawm ntau yam ua haujlwm hauv engineering. Pultrusion molding yog los sib sau ua ke ntawm cov txheej txheem prepreg (xov paj) hauv ib pawg pultrusion pwm, thiab prepreg yog ib qho ua ntej impregnated thaum pultrusion tseem nyob hauv, lossis lwm yam impregnation. Txoj kev impregnation dav dav yog cov fiber ntau ua ke impregnation thiab hmoov liquefying txaj impregnation.
