Ndi chitukuko chopitilira zinthu zophatikizika, kuwonjezera pa pulasitiki zolimbikitsira mitembo, kaboni 3 Mikangano ya karbon Ndi mawu omwe amagwiritsidwa ntchito pofotokoza zinthu zolimbitsa thupi zomwe zimagwiritsa ntchito ulusi wa kaboni ngati gawo lalikulu.
Gome la Zinthu:
1.
2. Njira yowumba ya pulasitiki yamoto yolimbikitsidwa
3. Katundu wa polymer olimbikitsidwa
4. Ubwino wa CFRP
5. Zovuta za CFRP
6. Carbon Prite Plaptive Overform
Carbon mbiti yolimbika
Phatilo la pulasitiki kufiririka ndi chinthu chopangidwa ndi zida za kaboni kupangidwira munjira inayake ndikugwiritsa ntchito zida za polymer. Dongosolo la ma carbon Firbon ndiocheperako, pafupifupi 7 ma microns, koma mphamvu zake zimakhala zazitali kwambiri.
Chiwonetsero choyambirira kwambiri cha mtundu wa mpweya chophatikizika ndi chosindikizira Carbon chiwonetsero cha Carbon. Zopangira zoyambira za carbon filaments zimayambitsa polyacrylonile (poto), rayon, kapena phula la petroleum. Mavitambo a kaboni amapangidwa kukhala nsalu za kaboni
Polymer nthawi zambiri imakhala yopanda ma thermoseting monga epoxy. Mafupa ena kapena ma polity a thermoplastic amagwiritsidwa ntchito, monga acevinyl acetate kapena nylon. Kuphatikiza pa ulusi wa kaboni, ma companos amathanso kukhala ndi aaramid Q, ma solecular olemera olemera polyethylene, aluminium, kapena ulusi wagalasi. Zogulitsa za mpweya womaliza kaboni fiber zimathanso kukhudzidwa ndi mtundu wa zowonjezera zomwe zimayambitsidwa mu matrix.
Njira yowumbirayo ya pulasitiki yamoto yolimbikitsidwa
Zogulitsa za kaboni zimafinya makamaka ndizosiyana chifukwa cha njira zosiyanasiyana. Pali njira zambiri zopangira zida za polymer zolimbikitsira mitanda.
1. Njira yogona
Ogawidwa mu njira yowuma (shopu yokonzekera isanakwane) ndi njira yonyowa (nsalu ya fiber ndikuyipitsidwa kuti mugwiritse ntchito). Kugona kwa dzanja kumagwiritsidwanso ntchito kukonza njira zogwiritsira ntchito njira yachiwiri youmbidwa monga kuponderezedwa. Njirayi ndi pomwe ma sheet a nsalu ya carbon adasokonekera pa nkhungu kuti apange chinthu chomaliza. Mphamvu ndi kuuma kwazinthu zomwe zimapangidwira zimakonzedwa posankha kuyimitsidwa ndikuluka mu ulusi wa nsalu. Ndewa imadzaza ndi epoxy ndikuchiritsidwa ndi kutentha kapena mpweya. Njira yopanga iyi nthawi zambiri imagwiritsidwa ntchito ngati magawo osapanikizika, monga injini zophimba.
2. Njira Yopanga Vuluum
Kwa okonzekera bwino, ndikofunikira kugwiritsa ntchito kukakamiza njira ina kuti mumvetsetse nkhungu ndikuchiritsa ndikuzikhazikitsa kutentha ndi kupanikizika. Njira ya Thumba ya BUPUMIM imagwiritsa ntchito mulu wa vatuum kuti ituluke mkati mwa thumba lopanga kuti kupanikizika pakati pa thumba ndipo nkhungu imapanga kukakamizidwa kuti zinthu zophatikizika zitheke.
Pamaziko a njira yagawani ya vacuum, njira yosinthira ya Augumlave idachokera pambuyo pake. Autoclaives amapereka zipsinjo zapamwamba komanso kutentha kuchiritsa gawo (m'malo mwa kuchiritsa kwachilengedwe) kuposa njira zopezera chikwama. Gawo lotereli lili ndi kapangidwe kake, malo abwinoko, amatha kuthetsa ma bubkets a mpweya (thovu lidzakhudza kwambiri mphamvu ya gawo), ndipo khalidwe lonse ndilokwera. M'malo mwake, njira yogwiritsira ntchito vacuum imafanana ndi filimu yomata. Kuchotsa thovu la ndege ndi ntchito yayikulu.
3. Njira Yopanga Moder
Kupanga Kupanga Kuumbandi njira yowumbira yomwe imathandizira kupanga misa ndi mafuta ambiri. Maunjeme nthawi zambiri amapangidwa ndi mbali zapamwamba komanso zotsika, zomwe timatcha nkhungu chachimuna ndi nkhungu yachikazi. Njira youmba ndikuyika zitsamba zopangidwa ndi pubses yopanga chitsulo, ndipo pansi pa kutentha kwamphamvu komanso kupanikizika, ndikuumba pang'onopang'ono, ndipo ndikuumba kuti apeze zinthu. Komabe, njirayi ili ndi mtengo woyambirira woposa zomwe kale, chifukwa nkhungu imafuna cnc yopepuka kwambiri.
4. Kuumba
Kwa magawo omwe ali ndi mawonekedwe ovuta kapena mawonekedwe a thupi la chisinthiko, Wifment Wift ikhoza kugwiritsidwa ntchito popanga gawo poyendetsa bwino pa Mandrel kapena Pakatikati. Pambuyo pa mphepo ikachiritsa ndikuchotsa mandrel. Mwachitsanzo, mikono yolumikizira ya tubular yogwiritsidwa ntchito poyimitsidwa imatha kupanga pogwiritsa ntchito njirayi.
5. Tsatirani Sinthani Kuumba
Tsimikizani kusinthasintha (RTM) ndi njira yotchuka youmba. Masitepe ake oyambira ndi awa:
1. Ikani nsalu yotsekemera ya carbon mu nkhungu ndikutseka nkhungu.
2. Jekeser madzi armoseting kukhalamo, kusiya zinthu zolimbitsa thupi, ndi kuchiritsa.
Katundu wa polymer olimbikitsidwa
(1) Mphamvu yayikulu ndi yolemetsa bwino.
Mphamvu zake (ndiye kuti, kuchuluka kwa mphamvu zokhala ndi mphamvu) za kaboni Mowalus wapaderayo (ndiye kuti chiwerengero cha achinyamata cha achinyamata kuchulukitsa, chomwe ndi chizindikiro cha zotupa za chinthu) ndi zoposa katatu ka zitsulo kapena zitsulo.
Ndi mphamvu zapamwamba kwambiri, zimatha kukhala ndi katundu wamkulu. Kukakamizidwa kwakukulu kumatha kufikira 350 kg / cm2. Kuphatikiza apo, zimakhala zolemeniza komanso zotsalira kuposa zoyera za F-4 ndi kuluka.
(2) Kuletsa kutopa komanso kuvala kukana.
Kusakaniza kwake kutopa ndikokwera kwambiri kuposa epoxy utomoni komanso wapamwamba kuposa wa zitsulo. Zithunzi zokongola zimakola komanso kukhala ndi mikangano yaying'ono. Kuchuluka kwa kuvala kuli nthawi 5-10 kocheperako kuposa zomwe zimapangidwa ndi zinthu zambiri za Asbestos kapena zoopsa za F-4.
(3) Zochita zabwino komanso kukana kutentha.
Mapulogalamu a Carbon Okhazikika a Carbon ali ndi mawonekedwe abwino, ndipo kutentha komwe kumapangidwa ndi mikangano kumasungunuka mosavuta. Mkati sikophweka kusokoneza ndi kusungira kutentha ndipo itha kugwiritsidwa ntchito ngati zinthu zamphamvu kwambiri. Mlengalenga, imatha kugwira ntchito mokhazikika pamatenthedwe a -120 ~ 350 ° C. Ndi kuchepetsa zitsulo za alkalimi mu kaboni, kutentha kwa ntchito kumatha kukulira. Pakati pa mpweya, kutentha kwake kosasinthika kumatha pafupifupi 2000 ° C, ndipo kumatha kupirira kusintha kwakukuru kuzizira komanso kutentha.
(4) Kuzunza bwino.
Sizovuta kuthetsa kapena kusokonekera, ndipo ndi chinthu chabwino kwambiri pakuchepetsa kwa kuwononga ndi kusanthula kwa phokoso.
Ubwino wa CFRP
1. Kulemera
Phukusi lachikhalidwe chinyezi limagwiritsa ntchito ulusi wagalasi wopitilira ndi magalasi okwanira 70% (kulemera kwagalasi / kulemera kwathunthu) ndipo nthawi zambiri amakhala ndi mapaundi a 0.065 pa inchi. CFRP comrosute yokhala ndi kulemera kwa 70% yomwe ili ndi mapaundi 0,555 pa kiyubic inchi.
2. Mphamvu zazikulu
Ngakhale ma poifere opumira a kaboni amalimbikitsidwa, ma cookitala a CFRP ali ndi mphamvu zambiri komanso okhwima pa unit olemera kuposa mitundu ya miyambo ya mikangano yamagalasi. Poyerekeza ndi zida zachitsulo, mwayiwu ndi wowonekera kwambiri.
Zoyipa za CFRP
1. Mtengo wokwera kwambiri
Mtengo wopanga wa pulasitiki wa carbon chikhazikitso ndi woletsa. Mitengo ya carbon imatha kukhala yosiyana kwambiri malinga ndi misika yamakono (yopezeka ndi zofuna), mtundu wa kaboni Pamwamba mapaundi-mapaundi, namwali kaboni kwambiri amatha kukhala 5 mpaka 25 okwera mtengo kuposa fiber. Kusiyana kumeneku kumakulirapo poyerekeza zitsulo kwa cfrp.
2.
Izi ndiye mwayi komanso zovuta za kaboni. Zimatengera ntchito. Mitundu ya kaboni imachititsa kwambiri kuti ulusi wagalasi ndi wokakamira. Zinthu zambiri zimagwiritsa ntchito fiberglass m'malo mwa kaboni kapena chitsulo chifukwa amafunikira kusokonekera. Popanga zida, zinthu zambiri zimafuna kugwiritsa ntchito ulusi wagalasi.
Magwiridwe a Phative Attive
Mapulogalamu a polymer a Polymer a Carbon ali ndi moyo wotalikirapo, kuchokera kumakina opangira zida zankhondo.
(1)Monga kulongedza
Zinthu za PTFFICE za PTFFF Farmate zolimbikitsidwa zimatha kupangidwa mwa kugonjetsedwa, kuvala zosemphana ndi zopindika kwambiri kapena kulongedza. Mukamagwiritsa ntchito kusindikiza, moyo wautumiki umakhala wautali, wopitilira 2 kanthawi kokwanira kuyika mafuta a Asbestos. Imatha kukhalabe ndi kusindikiza komwe kumapangitsa kuti zisinthe komanso kuziziritsa mwachangu komanso kutentha mwachangu. Ndipo popeza zinthuzo mulibe zinthu, palibe chimbudzi champhamvu chomwe chidzachitike pazitsulo.
(2)monga zopera
Kugwiritsa ntchito zokongoletsera zake, zitha kugwiritsidwa ntchito ngati manenedwe, magiya, ndi mphete za piston za zolinga zapadera. Monga zonunkhira zothira mafuta aulere kwa zida zamagetsi zamapiko, zojambulidwa ndi mafuta opangira magetsi magetsi (kupewa mphete zopangidwa ndi mafuta, zomwe zingagwiritsidwe ntchito mafuta pogwiritsa ntchito mawonekedwe ake osakhala olakwika.
. Choyambirira chinagwiritsidwa ntchito koyamba pa ndege zopanga kuti muchepetse ndegeyo ndikusintha njira yoyendetsera ndege. Amagwiritsidwanso ntchito mu mankhwala, mafuta, mphamvu zamagetsi, makina, ndi mafakitale ena monga chisindikizo champhamvu kapena zosindikizira zosiyanasiyana.
