Ma fiberglass composites amatanthauza fiberglass ngati thupi lolimbitsa, zinthu zina zophatikizana ngati matrix, kenako pambuyo pokonza ndi kupanga zinthu zatsopano, chifukwa chazopangidwa ndi fiberglassIli ndi makhalidwe ena, kotero kuti yagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, pepalali likusanthula zina mwa makhalidwe a fiberglass composites ndikupereka zina mwa zomwe zikuchitika pakukula kwake ndi malingaliro ake kuti timvetsetse bwino za ulusi wagalasi ndipo kafukufuku wa composites amachita gawo lofunika pakutchula.

Makhalidwe akuluakulu a fiberglass composites:
1. Kapangidwe kabwino kwambiri ka makina.Mphamvu yokoka ya fiberglass composites ndi yotsika kuposa yachitsulo, yokwera kuposa ya chitsulo chosungunuka ndi konkire, pomwe mphamvu yeniyeniyo ndi pafupifupi katatu kuposa yachitsulo ndi nthawi 10 kuposa ya chitsulo chosungunuka.
2. Kukana dzimbiri kwabwino.Pogwiritsa ntchito njira yoyenera yosankhira zinthu zopangira komanso kapangidwe ka sayansi kokhuthala, zinthu zopangidwa ndi fiberglass zingagwiritsidwe ntchito kwa nthawi yayitali m'malo okhala ndi zinthu zachilengedwe monga asidi, alkali ndi mchere.
3. Kuteteza kutentha bwino.Zipangizo zopangidwa ndi fiberglass zimakhala ndi mphamvu yotsika ya kutentha, ndipo zimakhala ndi mphamvu yabwino kwambiri yotetezera kutentha, choncho, ngati kutentha kulibe kusiyana kwakukulu, sizifunikira kutetezedwa kwapadera, ndipo zimatha kubweretsa zotsatira zabwino zoteteza kutentha.
4. Chiŵerengero chaching'ono cha kutentha kwa kutentha.Chifukwa cha kuchuluka kochepa kwa kutentha kwa zinthu zopangidwa ndi fiberglass, zimatha kugwiritsidwa ntchito nthawi zambiri m'mikhalidwe yovuta monga pamwamba, pansi pa nthaka, pansi pamadzi, kuzizira kwambiri, chipululu ndi zina zotero.
5. Kuteteza magetsi kwabwino kwambiri.Ingagwiritsidwe ntchito popanga chotetezera kutentha. Chotenthetsera chamagetsi chapamwamba chimatha kusungabe mphamvu zabwino za dielectric. Kulowa kwa microwave ndi kwabwino, komwe kumagwiritsidwa ntchito potumiza mphamvu ndi madera ambiri omwe akukumba.

Chitukuko cha ulusimagalasi ophatikizikandi motere:
1. Pakadali pano, kuthekera kwa chitukuko cha fiberglass yogwira ntchito bwino ndi kwakukulu, makamaka ubwino wa fiberglass ya silika, fiberglass yogwira ntchito bwino ili ndi njira ziwiri zopititsira patsogolo chitukuko: choyamba ndikuyang'ana kwambiri pakuchita bwino, chachiwiri ndikuyang'ana kwambiri pakukula kwa mafakitale a kafukufuku waukadaulo wa fiberglass yogwira ntchito bwino, chadzipereka kukonza magwiridwe antchito a fiberglass yogwira ntchito bwino, pomwe chikuchepetsa ndalama ndikuchepetsa kuipitsa.
2. Pali zofooka zina pakukonzekera zipangizo: gawo la kukonzekera kwa fiberglass yogwira ntchito kwambiri limakhalabe galasi lopanda madzi, kuchuluka kwa ulusi woyambirira wa ulusi, mtengo wokwera ndi mavuto ena, ndipo nthawi yomweyo, mu ntchito zina zapadera sizingakwaniritse zofunikira za mphamvu ndi zina zotero. Kugwiritsa ntchito thermosetting resin ngati matrix, kukonzekera zipangizo zophatikizika kumakhala ndi zovuta zina pakukonza, zovuta zobwezeretsanso, zitha kugwiritsidwa ntchito kokha kudula njira yokonzanso yachiwiri, kubwezeretsanso kumatha kudyedwa ndi mankhwala apadera komanso othandizira amphamvu oxidizing, zotsatira zake sizoyenera, ngakhale kuti magetsi apangidwa ngati thermosetting resin yosinthika, koma mtengo wa vutoli uyenera kulamulidwa.
3. Mu njira yopangira fiberglass pogwiritsa ntchito ukadaulo wosiyanasiyana wopangira kuti akonze mtundu watsopano wa zinthu zopangidwa ndi ulusi wagalasi, m'zaka zaposachedwa, kuti akwaniritse zosowa za zinthu zosiyanasiyana zapadera, chitukuko cha ukadaulo wosiyanasiyana pamwamba pa fiberglass kuti achite chithandizo chapadera chosintha, kusintha pamwamba ndiye njira yatsopano mtsogolomu yopangira ukadaulo wokonzekera zinthu zopangidwa ndi fiberglass.
4. Kufunika kwa msika wapadziko lonse m'nthawi ikubwerayi, makamaka kufunikira kwa mayiko omwe akutukuka kumene kudzapitirirabe kukula, ndipo ubwino wa atsogoleri amakampani udzaonekera bwino.Zosakaniza zagalasi la fiberglassZakhala chimodzi mwa zipangizo zazikulu zopangira magalimoto, fiberglass thermoplastic zipangizo zikuchulukirachulukira chifukwa cha kulimba kwawo komanso kubwezeretsanso bwino, kugwiritsa ntchito fiberglass thermoplastic zipangizo zolimbitsa thupi zomwe zimagwiritsidwa ntchito kwambiri pagawoli, kuphatikizapo dashboard bracket, front-end bracket, bumper ndi engine peripheral parts, kuti zikwaniritse zigawo zambiri za galimoto yonse ndi zigawo za substructural za chivundikiro. Kugwiritsa ntchito kwa fiberglass thermoplastic reinforcement zipangizo kumaphatikizapo chida cha instrument panel bracket, front end bracket, bumper ndi engine peripheral parts, zomwe zimapangitsa kuti zigawo zambiri ndi zigawo za substructural za galimoto yonse zigwiritsidwe ntchito.
