Kev tsim cov cuab yeej ntawm kev ua haujlwm siab thermoplastic composites feem ntau yog hloov los ntawm thermosetting resin composites thiab hlau sib sau tshuab. Raws li cov khoom sib txawv, nws tuaj yeem muab faib ua molding, ob chav zaj duab xis molding, autoclave molding, lub hnab nqus tsev molding, filament winding molding, calendering molding, thiab lwm yam. kev taw qhia, kom koj tuaj yeem muaj kev nkag siab ntau dua ntawm cov thermoplastic carbon fiber ntau.

1. Muab ob npaug rau zaj duab xis
Ob chav membrane molding, tseem hu ua resin membrane infiltration molding, yog ib txoj kev tsim los ntawm ICI tuam txhab los npaj cov khoom sib xyaw nrog prepreg. Txoj kev no yog qhov zoo rau kev molding thiab kev ua haujlwm ntawm qhov nyuaj.

Nyob rau hauv ob chav zaj duab xis tsim, txiav prepreg yog muab tso rau ntawm ob txheej ntawm deformable saj zawg zog resin zaj duab xis thiab hlau zaj duab xis, thiab periphery ntawm zaj duab xis yog kaw nrog hlau los yog lwm yam ntaub ntawv. Hauv kev tsim cov txheej txheem, tom qab cua sov mus rau qhov ntsuas kub, ib qho kev sib sau siab yog siv, thiab cov khoom yog deformed raws li cov duab ntawm cov hlau pwm, thiab thaum kawg txias thiab zoo li tus.

Nyob rau hauv cov txheej txheem ntawm ob chav zaj duab xis tsim, cov khoom thiab cov yeeb yaj kiab feem ntau yog ntim thiab nqus. Vim lub deformability ntawm zaj duab xis, qhov kev txwv ntawm resin txaus yog tsawg dua li ntawm cov pwm nruj. Ntawm qhov tod tes, cov yeeb yaj kiab deformed nyob rau hauv lub tshuab nqus tsev tuaj yeem ua rau lub siab tsis sib xws ntawm qhov chaw, uas tuaj yeem txhim kho lub siab hloov pauv ntawm qhov chaw thiab xyuas kom muaj qhov zoo.

2. Pultrusion molding
Pultrusion yog cov txheej txheem tsim khoom txuas ntxiv ntawm cov ntaub ntawv sib xyaw nrog ntu ntu ntu. Thaum xub thawj, nws tau siv los tsim cov khoom siv yooj yim nrog unidirectional fiber reinforced khoom cross-section, thiab maj mam tsim rau hauv cov khoom nrog cov khoom, hollow thiab ntau txoj kev hla ntu. Ntxiv mus, cov khoom ntawm profiles tuaj yeem tsim los ua kom tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev tsim vaj tsev.

Pultrusion molding yog txhawm rau muab cov kab xev prepreg (xov paj) nyob rau hauv ib pawg ntawm pultrusion pwm. Lub prepreg yog pultruded thiab prepreg, los yog impregnated nyias. Txoj kev impregnation dav dav yog fiber ntau sib xyaw impregnation thiab hmoov liquefying txaj impregnation.

3. Siab Moulding
Daim ntawv prepreg raug txiav raws li qhov loj ntawm cov pwm, rhuab rau hauv lub qhov cub cua sov kom sov siab tshaj qhov kub ntawm cov resin melting, thiab tom qab ntawd xa mus rau qhov loj tuag rau kev kub ceev ceev. Lub voj voog molding feem ntau ua tiav hauv kaum vib nas this mus rau ob peb feeb. Cov txheej txheem molding no muaj kev siv hluav taws xob tsawg, cov nqi tsim khoom tsawg thiab kev tsim khoom siab. Nws yog txoj kev molding ntau tshaj plaws nyob rau hauv cov txheej txheem molding ntawm thermoplastic composites.

4. Winding txoj kev
Qhov sib txawv ntawm filament winding ntawm thermoplastic composites thiab thermosetting composites yog tias cov xov paj prepreg (kab xev) yuav tsum tau rhuab mus rau qhov muag muag thiab rhuab ntawm qhov chaw sib cuag ntawm mandrel.

Cov txheej txheem cua sov feem ntau suav nrog cov cua kub cua sov, dielectric cua sov, hluav taws xob cua sov, hluav taws xob hluav taws xob hluav taws xob, thiab lwm yam hauv cov cua sov ntawm hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob infrared (IR), microwave (MW) thiab RF cua sov kuj tau muab faib vim qhov sib txawv wavelength lossis zaus. ntawm electromagnetic yoj. Nyob rau hauv xyoo tas los no, laser cua sov thiab ultrasonic cua sov system kuj tau tsim.

Nyob rau hauv xyoo tas los no, cov txheej txheem tshiab winding tau tsim, suav nrog ib-kauj ruam molding txoj kev, uas yog, fiber ntau yog ua rau prepreg yarn (kab kab xev) los ntawm boiling liquefaction txaj ntawm thermoplastic resin hmoov, thiab ces ncaj qha rau ntawm lub mandrel; Tsis tas li ntawd, los ntawm cov txheej txheem cua sov, uas yog, carbon fiber prepreg yarn (kab xev) yog ncaj qha hluav taws xob, thiab cov thermoplastic resin yog yaj los ntawm electrifying thiab cua sov, kom cov fiber ntau (kab xev) tuaj yeem raug mob rau hauv cov khoom; Qhov thib peb yog siv neeg hlau rau winding, txhim kho qhov raug thiab automation ntawm winding khoom, yog li nws tau txais kev saib xyuas zoo.
