Ukadaulo wopangira makina opangira ma thermoplastic apamwamba kwambiri amasiyidwa kuchokera ku ma thermosetting resin composites ndiukadaulo wopanga zitsulo.Malinga ndi zipangizo zosiyanasiyana, zikhoza kugawidwa mu akamaumba, awiri filimu akamaumba, autoclave akamaumba, zingalowe thumba akamaumba, filament wokhotakhota akamaumba, calendering akamaumba, etc. Mu njira zimenezi, ife kusankha angapo ntchito akamaumba njira kukupatsani mwachidule akamaumba. mawu oyamba, kuti muthe kumvetsetsa bwino za ma composites a thermoplastic carbon fiber.

1. Pawiri filimu kupanga
Kuumba kwa membrane iwiri, komwe kumadziwikanso kuti resin membrane infiltration molding, ndi njira yopangidwa ndi kampani ya ICI yokonzekera zigawo zophatikiza ndi prepreg.Njirayi imathandizira kuumba ndi kukonza magawo ovuta.

Pakupanga filimu iwiri, prepreg yodulidwa imayikidwa pakati pa zigawo ziwiri za filimu yosinthika yosinthika ya utomoni ndi filimu yachitsulo, ndipo filimuyi imasindikizidwa ndi zitsulo kapena zipangizo zina.Popanga mapangidwe, mutatha kutentha kwa kutentha kwa kupanga, kupanikizika kwina kumapanga kumagwiritsidwa ntchito, ndipo zigawozo zimapunduka molingana ndi mawonekedwe a nkhungu yachitsulo, ndipo pamapeto pake zimakhazikika ndi mawonekedwe.

Popanga filimu iwiri, mbali ndi mafilimu nthawi zambiri amapakidwa ndi kupukutidwa.Chifukwa cha kupunduka kwa filimuyo, kuletsa kutuluka kwa utomoni kumakhala kochepa kwambiri poyerekeza ndi nkhungu yolimba.Kumbali ina, filimu yopunduka pansi pa vacuum imatha kukakamiza mbali zina, zomwe zimatha kusintha kusinthasintha kwa zigawozo ndikuwonetsetsa kuti zimapanga bwino.

2. Kujambula kwa pultrusion
Pultrusion ndi njira yopitilira yopanga mbiri yophatikizika yokhala ndi magawo osiyanasiyana.Poyambirira, idagwiritsidwa ntchito popanga zinthu zosavuta zokhala ndi unidirectional unidirectional wolimbitsa gawo lolimba, ndipo pang'onopang'ono zidayamba kukhala zopangidwa ndi magawo olimba, opanda kanthu komanso osiyanasiyana ovuta.Kuphatikiza apo, mawonekedwe a mbiriyo amatha kupangidwa kuti akwaniritse zofunikira zamaukadaulo osiyanasiyana.

Kujambula kwa pultrusion ndikuphatikiza tepi ya prepreg (ulusi) mu gulu la nkhungu za pultrusion.The prepreg mwina pultruded ndi prepreg, kapena impregnated mosiyana.Njira zambiri zoyamwitsa ndi kuphatikizika kwa ulusi wophatikizika ndi kulowetsedwa kwa bedi la ufa.

3. Pressure Molding
Tsamba la prepreg limadulidwa molingana ndi kukula kwa nkhungu, kutenthedwa mu ng'anjo yotentha mpaka kutentha kwambiri kuposa kutentha kwa utomoni, ndiyeno imatumizidwa kukufa kwakukulu kuti ikanikize mwachangu.The akamaumba mkombero zambiri anamaliza mu masekondi khumi kwa mphindi zochepa.Njira yamtunduwu imakhala ndi mphamvu zochepa, zotsika mtengo zopangira komanso zokolola zambiri.Ndiwo njira yodziwika kwambiri yopangira ma thermoplastic composites.

4. Kupanga mafunde
Kusiyana kwa ulusi wokhotakhota wa ma composites a thermoplastic ndi ma thermosetting composites ndikuti ulusi wa prepreg (tepi) uyenera kutenthedwa mpaka kufewetsa ndikutenthedwa pamalo olumikizana ndi mandrel.

Njira zodziwika bwino za kutentha zimaphatikizapo kutentha kwa conduction, kutentha kwa dielectric, kutentha kwamagetsi, kutentha kwamagetsi, kutentha kwamagetsi, ndi zina zotero. Mu kutentha kwa ma radiation a electromagnetic, ma radiation a infrared (IR), microwave (MW) ndi kutentha kwa RF amagawidwanso chifukwa cha kutalika kwa kutalika kapena mafupipafupi. mphamvu ya electromagnetic wave.M'zaka zaposachedwapa, laser Kutentha ndi akupanga Kutentha dongosolo nawonso anayamba.

M'zaka zaposachedwapa, latsopano mapiringidzo ndondomeko wakhala anayamba, kuphatikizapo sitepe akamaumba njira, ndiye CHIKWANGWANI wapangidwa prepreg ulusi (tepi) ndi otentha liquefaction bedi la thermoplastic utomoni ufa, ndiyeno mwachindunji bala pa mandrel;Kuonjezera apo, kupyolera mu njira yopangira kutentha, ndiko kuti, ulusi wa carbon fiber prepreg (tepi) umakhala ndi magetsi, ndipo utomoni wa thermoplastic umasungunuka ndi electrifying ndi kutentha, kotero kuti ulusi wa fiber (tepi) ukhoza kuphulika muzinthu;Chachitatu ndikugwiritsa ntchito loboti yokhotakhota, kukonza zolondola komanso zodziwikiratu za zinthu zozungulira, motero zalandira chidwi chachikulu.
