Waxqabadka sare ee maaddada fiber-carbon waxay ka dhigaysaa waxqabad codsi oo aad u sarreeya ee warshado badan.Markafiber carbonbadeecada waa la dabaqaa, waxaa la ogaaday in qiimaha guud uu sarreeyo.Meesha uu qiimihiisu sarreeyo badeecada fiber-ka jaban waxay leedahay meelo badan.Kooxdayadu waxay kaaga sheegi doonaan aragtida fiber carbon.
Badeecadaha kaarboonka ee aynu aragno runtii aad ayay uga duwan yihiin agabkayaga fiber-carbon, sababtoo ah fiilooyinka lama soo saari karo kaligood, waana in lagu daraa matrix resin si loo dhamaystiro wax soo saarka alaabta.Mid ka mid ah sababaha qiimaha alaabooyinka fiber-ka ay qaali u yihiin ayaa ah in qiimaha fiilooyinka kaarboonku uu aad u sarreeyo, marka waa in aan marka hore fahamnaa walxaha jiidista fiber-ka carbon.
Waxaa jira saddex nooc oo jiidista fiber-ka jaban, oo ay ku jiraan polyacrylonitrile (PAN) -fiber carbon fiber ku salaysan, fiber carbon-ku-salaysan iyo fiber carbon-ku-salaysan xanjo.Fiber carbon-ku-salaysan ee ugu caansan ee PAN-ku-ku-salaysan dhab ahaantii waa kan ugu caansan, guud ahaanna saamiga suuqyadu waa in ka badan 90%, markaa fibbarka kaarboonka ee heerkulbeegga ah ee hadda jira asal ahaan waxa loola jeedaa fiber-karboon-ku-saleysan PAN.
Polyacrylonitrile ayaa sidoo kale la allifay bilowgii hore.Waxaa alifay Akio Kondo ee Japan 1959-kii, ka dibna wax-soo-saar ballaaran laga sameeyay Toray 1970. Dhammaan fiilaha kaarboon polyacrylonitrile wuxuu leeyahay awood aad u sarreeya iyo sifooyinka xiddigta modelka.Fiber-ku-saleysan asphalt-ka waxaa soo saartay Jaamacadda Gunma ee Japan 1965-kii. Jiidashada fiber-ka-carbon-ka waxay leedahay kororka kulaylka oo aad u sarreeya ilaa 90OGPa, sidaa darteed inta badan waxaa lagu dabaqaa agabyo shaqeynaya oo gaar ah.Fiber-ka kaarboon-ku-salaysan ee Viscose-ku-salaysan waxa inta badan loo istcimaali jiray walxo isku-dhafan oo loogu talo-galay gaashaammada kulaylka hawada sare sannadihii 1950-aadkii, sidoo kalena waa shayga hadda la isticmaali doono.Markaa waxaan ogaanay in labadii hore ay ikhtiraaceen Jabbaan, waana sababta cabirka wax qabad ee jiidista fiber carbon uu ku salaysan yahay maadada fiber carbon Toray.
Dabcan, cilmi baarista iyo horumarinta horudhacyada jiidista fiber carbon ayaa sii waday horumarka sanadihii la soo dhaafay, laakiin saameynta guud wali ma dhicin.Maalmahan, PAN-ku-salaysan ayaa weli ah tiir-dhexaadka.Soo saarista fiilooyinka kaarboonka, wax-soo-saarka kaarboon ee saddexda hor-u-yaal waxay gaari karaan in ka badan B80%.Aragti ahaan, qiimaha fiilooyinka kaarboonka ee noocan oo kale ah ayaa hubaal ahaan doona mid hooseeya, laakiin wax soo saarka garoon-ku-saleysan wuxuu u baahan yahay in la sifeeyo oo la beddelo.Habkani wuxuu si weyn u kordhin doonaa kharashka wax soo saarka wuxuuna hoos u dhigi doonaa wax soo saarka ilaa 30%.Markaa kuwa PAN-ku-salaysan ayaa weli caan ah.
Haddaba aan eegno fibre kaarboonka PAN ee sida weyn loo isticmaalo.Qiimaha kaarboon-ku-saleysan ee PAN aad ayuu uga hooseeyaa kan kaarboonka ku salaysan asphalt, waxaana lagu dabaqi karaa meelo badan.Qiimaha fiber-ku-saleysan PAN ee satalaytka ayaa ah mid aad u sarreeya ilaa 200 yen/kg, halka qiimaha kaarboonka ee baabuurta uu hooseeyo 2,000 yen/kg.
Kadibna waxaan wali u isticmaalnaa maadada fiber carbon Toray sida saldhigga.Halkan, fiilooyinka jajaban ee PAN-ku salaysan waxay u qaybsan yihiin jiido waaweyn iyo kuwo yaryar.Tusaale ahaan, qiimaha 3K ee caadiga ah waa 50-70 US dollars/kg, qiimaha 6K waa 4-50 US dollars/kg.Sidaa darteed, waxaan sidoo kale fahmi karnaa sababta jiidista yaryar loogu isticmaalo goobaha waxqabadka sare leh.
Sidaa darteed, waxaanu leenahay qiimaha fiber carbon wuxuu noqon doonaa mid aad qaali u ah.Sabab la'aan maaha in ay wax badan ku lug leedahay alaabta ceeriin.Intaa waxaa dheer, qiimaha alaabooyinka fiber carbon waa mid aad u sarreeya, waxayna leedahay wax badan oo ku saabsan xaqiiqda ah in alaabtayada fiber-ka carbon ay u baahan yihiin shaqaale iyo qalab badan.
