Kusanthula ndi kugwiritsa ntchito njira yokhotakhota ya FRP

Fiber winding ndi imodzi mwazinthu zopangira ma resin matrix composites.Pali mitundu itatu ikuluikulu yokhotakhota: mafunde a toroidal, mapindikidwe a ndege ndi mafunde ozungulira.Njira zitatuzi zili ndi mawonekedwe awoawo, ndipo njira yokhotakhota yonyowa ndiyomwe imagwiritsidwa ntchito kwambiri chifukwa cha zida zake zosavuta komanso zotsika mtengo zopangira.

Pansi pa kuwongolera kupsinjika ndi mawonekedwe a mzere wokonzedweratu, ulusi wopitilira kapena nsalu yomwe imayikidwa ndi guluu wa utomoni imavulala mosalekeza, molingana komanso pafupipafupi pa nkhungu yayikulu kapena pamzere pogwiritsa ntchito zida zapadera zomangira, kenako ndikukhazikika pansi pa malo ena otentha kuti akhale kompositi zakuthupi akamaumba njira zina mawonekedwe mankhwala.Chithunzi chojambula cha fiber winding molding process:

Pali mitundu itatu ikuluikulu yokhotakhota (FIG. 1-2): toroidal winding, planar winding ndi spiral winding.Imbani ku zida zolimbikitsidwa za nkhungu ndi olamulira pachimake pafupi ndi madigiri a 90 (kawirikawiri 85-89) motsogozedwa ndi mafunde osalekeza pa mandrel, zida zolimba zomwe zili ndi maziko a masanjidwewo pa malekezero onse a dzenje lamtengowo komanso mosalekeza. zokhotakhota mu malangizo a ndege pa mandrel, kozungulira bala analimbitsa zakuthupi ndi tangent pa malekezero onse a mandrel, koma pa ozungulira mandrel mosalekeza akupiringa pa mandrel.

Kukula kwa ukadaulo wa fiber winding kumagwirizana kwambiri ndi chitukuko cha zida zolimbikitsira, kachitidwe ka utomoni ndi zida zaukadaulo.Ngakhale mu Mzera wa Han, njira yopangira ndodo za zida monga Gorilli ndi halberd zitha kupangidwa ndi kuyika lacquer ndi mitengo yayitali yamatabwa kuphatikiza nsungwi zazitali ndi silika wozungulira, njira yopangira zida zopangira zida sizinakhale ukadaulo wopanga zinthu mpaka 1950s.Mu 1945, chida choyamba choyimitsira magudumu opanda masika chinapangidwa bwino ndi ukadaulo wokhotakhota ulusi, ndipo mu 1947, makina oyamba omangira ulusi adapangidwa.Ndi chitukuko cha ulusi mkulu ntchito monga mpweya CHIKWANGWANI ndi aramong CHIKWANGWANI ndi maonekedwe a microcomputer ankalamulira mapiringidzo makina, CHIKWANGWANI mapiringidzo ndondomeko, monga kwambiri limakanizidwa gulu zipangizo luso kupanga, wakhala mofulumira anayamba, ndipo wakhala ntchito pafupifupi m'madera zotheka. kuyambira 1960s.

Zambiri zaife:ayiMalingaliro a kampani Yuniu Fiberglass Manufacturing Co., Ltd.Ife makamaka kubala ndi kugulitsa mankhwala e-mtundu fiberglass, monga fiberglass roving, fiberglass akanadulidwa silika, fiberglass akanadulidwa anamva, fiberglass gingham, anamva singano, nsalu fiberglass ndi zina zotero.Ngati mukufuna, chonde tithandizeni momasuka.

Malingana ndi kusiyanandi chemchikhalidwe ndi thupi of utomoni gawo lapansi pa kuzimata, kukulunga teNjira zitha kugawidwa m'njira zowuma, zonyowa komanso zowuma:

1. Zouma

Kumangirira kowuma kumatengera tepi yoyimitsidwa kale pagawo B pambuyo pa kuyimitsidwa.Mizere yomwe ili ndi mimba imapangidwa ndikuperekedwa muzomera zapadera kapena ma workshop.Pakumangirira kouma, lamba wa ulusi woviikidwa kale uyenera kutenthedwa ndi kufewetsa pamakina omangirira asanavulazidwe ku nkhungu yapakati.Ubwino wa ulusi wa prepreg ukhoza kuwongoleredwa molondola chifukwa zomwe zili ndi guluu, kukula kwake ndi mtundu wa tepi zitha kuzindikirika ndikuwunikiridwa musanapume.Kuchita bwino kwa mafunde owuma ndikokwera, kuthamanga kwa mafunde kumatha kufika 100-200m / min, ndipo malo ogwirira ntchito ndi oyera.Komabe, zida zowuma zowuma zimakhala zovuta komanso zokwera mtengo, ndipo mphamvu yakumeta ubweya wa interlaminar ya zinthu zomangira ndi yotsika.

2. Yonyowa

Njira yokhotakhota yonyowa ndikumangirira ulusi pachimake kufa molunjika pansi pazowongolera pambuyo pa mtolo ndikuviika guluu, kenako kulimba.Zida zomangira zonyowa ndizosavuta, koma chifukwa lamba wa ulusi amavulazidwa atangoviika, zimakhala zovuta kuwongolera ndikuwunika zomwe zili mu guluu panthawi yokhotakhota.Pakalipano, zolakwika monga thovu ndi pores amapangidwa mosavuta mu mankhwala pamene zosungunulira mu njira guluu olimba, ndipo kukanika kumakhalanso kovuta kulamulira pa mapiringidzo.Panthawi imodzimodziyo, ogwira ntchito amagwira ntchito mumlengalenga wosungunula komanso chilengedwe cha ubweya wowuluka wa tsitsi lalifupi, malo ogwira ntchito ndi osauka.

3. Njira yowuma

Poyerekeza ndi njira yonyowa, njira yowumayi imawonjezera zida zowumitsa panjira kuchokera ku ulusi wothira mpaka kupindika mpaka pachikombole chapakati, ndikuthamangitsa zosungunulira mu njira ya guluu ya tepi ya ulusi.Mosiyana ndi ndondomeko youma, ndondomeko ya semi-dry sichidalira zida zovuta za preimpregnation.Ngakhale guluu zili mankhwala si zophweka molondola kulamulira mu ndondomeko yonyowa ndi kuposa ya yapakatikati kuyanika zida kuposa njira yonyowa, mphamvu ya ntchito ya ogwira ntchito ndi wamkulu, koma kuwira, porosity ndi zolakwika zina mu mankhwala kwambiri yafupika.

Njira zitatuzi zili ndi mawonekedwe awoawo, ndipo njira yokhotakhota yonyowa ndiyomwe imagwiritsidwa ntchito kwambiri chifukwa cha zida zake zosavuta komanso zotsika mtengo zopangira.Ubwino ndi kuipa kwa njira zitatu zokhotakhota zikuyerekezeredwa mu Table 1-1.

Gulu 1-1 Chiŵerengero cha njira zikwi khumi za njira zitatu zokhotakhota
