1. Chiyambi cha Njira Yopangira Ma Chubu

Kudzera mu phunziroli, muphunzira momwe mungagwiritsire ntchito njira yozungulira chubu kuti mupange mapangidwe a chubu pogwiritsa ntchito makina ozungulira chubu a carbon fiber, motero mupanga mphamvu zambiri.machubu a ulusi wa kaboniNjira imeneyi imagwiritsidwa ntchito kwambiri ndi opanga zinthu zophatikizika.

Ngati mukufuna kupanga machubu okhala ndi mbali zofanana kapena zopingasa mosalekeza, njira yozungulira machubu ndiyo chisankho chabwino. Chomwe mukufunikira ndi mandrel yachitsulo ya kukula koyenera ndi uvuni kuti mupange machubu a carbon fiber opangidwa mwapadera omwe akugwirizana ndi zosowa zanu.

Pa machubu opangidwa ndi ulusi wa kaboni wooneka ngati zovuta, monga ma handlebar kapena mafelemu ovuta kwambiri monga mafoloko oimika kapena mafelemu a njinga, ukadaulo wopangidwa ndi ulusi wogawanika ndiye njira yabwino kwambiri. Tsopano tikuwonetsa momwe tingagwiritsire ntchito ukadaulo wopangidwa ndi ulusi wogawanika popanga machubu opangidwa ndi ulusi wa kaboni wovuta awa.

2. Kukonza ndi Kukonzekera Ma Mandrel a Chitsulo

• Kufunika kwa Ma Mandrel a Chitsulo

Musanayambe njira yozungulira chubu, gawo loyamba ndikukonzekera ma mandrel achitsulo. Ma mandrel achitsulo ayenera kufanana ndi m'mimba mwake wa machubu, ndipo kusalala kwawo pamwamba ndi kukonzedwa koyenera ndikofunikira kwambiri. Kuphatikiza apo, mandrel achitsulo ayenera kukonzedwa bwino, monga kuyeretsa ndikugwiritsa ntchito chotulutsira, kuti njira yochotsera ikhale yosavuta pambuyo pake.

Pa nthawi yozungulira chubu, mandrel yachitsulo imagwira ntchito yofunika kwambiri chifukwa iyenera kuthandizirakukonzekera kwa ulusi wa kabonikuti zitsimikizire kuti zikupindika bwino. Chifukwa chake, kukonzekera kukula koyenera kwa mandrel yachitsulo ndikofunikira kwambiri. Popeza ulusi wa kaboni udzazunguliridwa pamwamba pa mandrel, ulusi wakunja wa mandrel uyenera kufanana ndi ulusi wamkati wa chubu cha ulusi wa kaboni chomwe chikupangidwa.

• Kugwiritsa ntchito wothandizira kutulutsa

Zinthu zotulutsa zimachepetsa kukangana ndipo zimaonetsetsa kuti zikuyenda bwino; ziyenera kugwiritsidwa ntchito mofanana pamwamba pa mandrel. Pambuyo poti mandrel yachitsulo yakonzedwa, gawo lotsatira ndikugwiritsa ntchito chinthu chotulutsa. Zinthu zotulutsa zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo mafuta a silicone ndi parafini, zomwe zimachepetsa kukangana pakati pa ulusi wa kaboni ndi mandrel yachitsulo.

Pa mandrel yachitsulo yokonzedwa, tiyenera kuonetsetsa kuti ndi yoyera bwino komanso pamwamba pake pali posalala momwe tingathere kuti zinthuzo zisamawonongeke bwino. Pambuyo pake, chotulutsiracho chiyenera kugwiritsidwa ntchito mofanana pamwamba pa mandrel.

3. Kukonzekera kwa ulusi wa kaboni wokonzedwa kale

• Mitundu ndi ubwino wa prepreg

Ma prepreg a ulusi wa kaboni okha ndi omwe amakwaniritsa zofunikira zapamwamba kuti azigwira bwino ntchito komanso mosavuta. Ngakhale mitundu ina ya zinthu zolimbitsa, monga nsalu zouma zodzazidwa ndi epoxy, zitha kugwiritsidwa ntchito mwanjira yoti zigwire bwino ntchito, kwenikweni, ma prepreg a ulusi wa kaboni okha ndi omwe angakwaniritse zofunikira zapamwamba kuti zigwire bwino ntchito komanso mosavuta.

Mu phunziroli, tikugwiritsa ntchito njira yapadera yokonzekera zigawo kuti tiwongolere magwiridwe antchito a chubu.

• Kapangidwe ka Prepreg Layup

Chopangira chopangira choluka chimayikidwa mkati mwa chubu, kutsatiridwa ndi zigawo zingapo za chopangira choluka chimodzi, ndipo pamapeto pake chopangira china cha chopangira choluka chimayikidwa kunja kwa chubu. Kapangidwe kameneka kamagwiritsa ntchito bwino ubwino wa chopangira choluka cha chopangira choluka pa 0° ndi 90° axes, zomwe zimapangitsa kuti chubu chigwire bwino ntchito. Zambiri mwa zopangira zoluka chimodzi zomwe zimayikidwa pa 0° axis zimapangitsa kuti chitoliro chikhale cholimba kwambiri.

4. Chitoliro chozungulira njira yoyendera

• Kukonzekera koyambirira

Mukamaliza kupanga prepreg layup, njirayi imapitirira mpaka ku njira yozungulira chitoliro. Kukonzekera prepreg kumaphatikizapo kuchotsa filimu ya PE ndi pepala lotulutsa, ndikusunga malo oyenera olumikizana. Gawo ili ndilofunikira kwambiri kuti njira zozungulira zotsatira zipitirire bwino.

• Tsatanetsatane wa njira yozungulira

Pa nthawi yozungulira, ndikofunikira kuonetsetsa kuti ma prepreg azungulira bwino, ndipo shaft yachitsulo imayikidwa bwino ndipo mphamvu imayikidwa mofanana. Shaft yachitsulo iyenera kuyikidwa bwino m'mphepete mwa gawo loyamba la ma prepreg, kuonetsetsa kuti mphamvu ikugwiritsidwa ntchito mofanana.

Pakupindika, zinthu zina zokonzedweratu zitha kudulidwa kumapeto kuti zithandize kuchotsa zinthuzo panthawi yozichotsa.

• Kukulunga Filimu ya BOPP

Kuwonjezera pa prepreg, filimu ya BOPP ingagwiritsidwenso ntchito kukulunga. Filimu ya BOPP imawonjezera mphamvu yolimbitsa, imateteza, ndikutseka prepreg. Mukamagwiritsa ntchito filimu yokulunga ya BOPP, ndikofunikira kuonetsetsa kuti matepiwo akugwirizana mokwanira.

5. Njira Yophikira Uvuni

• Kutentha ndi Nthawi Yochiritsa

Pambuyo pokulunga bwino zinthu zolimbikitsidwa ndi ulusi wa kaboni wa prepreg, zimatumizidwa ku uvuni kuti ziume. Kulamulira kutentha ndikofunikira kwambiri panthawi youma mu uvuni, chifukwa mitundu yosiyanasiyana ya prepreg imakhala ndi mikhalidwe yosiyana youma. Gawoli ndi lofunika kwambiri pakutsimikizira kukhazikika kwa zinthu ndikuwonjezera magwiridwe antchito.

Kudzera mu kutentha kwambiri mu uvuni,ulusi wa kabonindipo resin matrix imachita zonse, ndikupanga zinthu zolimba zophatikizika.

6. Kuchotsa ndi Kukonza

Pambuyo pochotsa filimu yokulunga ya BOPP, chinthu chotsukidwacho chikhoza kuchotsedwa. Filimu ya BOPP ikhoza kuchotsedwa pambuyo potsukidwa. Ngati pakufunika, mawonekedwe ake akhoza kukonzedwanso kudzera mu kupukuta ndi kupaka utoto. Kuti muwonjezere kukongola, njira zina zomaliza monga kupukuta ndi kupaka utoto zitha kuchitika.
