Carbon fiberwaa wakiilka qalabka waxqabadka sare ee marxaladda hadda.Sababta ayaa ah in walxaha fiber carbon ay leeyihiin sifooyin awood aad u wanaagsan.Codsiyada wax ku oolka ah, faa'iidada miisaanka khafiifka ah waa in walxaha fiber carbon ay si fiican u bedeli karaan alaabada biraha dhaqameed.Faa'iidooyinka iftiinka sheyga, qaar ka mid ah degaannada gaarka ah, waxaa sidoo kale jira shuruudo sare oo loogu talagalay iska caabinta daxalka ee maaddada, markaa miyuu kaarboonka kaarboonku u adkaysanayaa?Maqaalkani wuxuu raaci doonaa tifaftiraha si uu u eego.
Iska caabinta daxalka ee fiber carbon waa mid aad u sarreeya.Tani waa sababta oo ah xasilloonida qaabdhismeedka fiber jabay ayaa wax badan ku leh.Soo saarista walxaha fiber carbon waxay u baahan tahay in lagu sifeeyo kumanaan C si meesha looga saaro wasakhda gudaha iyo canaasiirta kaarboonka.Habka lithification wuxuu sameeyaa qaab-dhismeedka microcrystalline kaarboon.Qaab dhismeedka maaddadan ayaa faa'iido u leh iska caabbinta daxalka dhexdhexaadka ah oo aad u sarreeya.Deegaanka 50% hydrochloric acid ama sulfuric acid fosfooraska, dhammaan sifooyinka farsamada ayaa si faahfaahsan loo qaabeeyey.Marka lagu daro dhexroorka lugaha si weyn uma beddeli doono, taas oo sidoo kale keenta faa'iidooyin waxqabad oo aad u wanaagsan oo u adkaysta nabaad-guurka walxaha fiber-ka.Tani waxay hubinaysaa in fiber-ka kaarboonku uu muujiyo faa'iido aad u wanaagsan ee iska caabbinta daxalka.
Waxaa la arki karaa in fiber carbon uu leeyahay wax qabad iska caabin ah oo aad u sarreeya.Laakiin loogu talagalayfiber carbonalaabooyinka, tani maahan kiiska, sababtoo ah fiber saafi ah si madaxbanaan looma soo saari karo alaabta fiber carbon.Haddii ay u baahan tahay matrix matrix ah, midka caadiga ah waa matrix matrix resin ah, iyo iska caabbinta daxalka ee alaabooyinka fiber carbon waa sida resinka oo kale.Matrixka laftiisa iyo dusha xidhiidhka ee u dhexeeya resin iyo fiber carbon ayaa sidoo kale wax badan ku leh.
Sidaa darteed, waxqabadka thisfiber carbonAlaabtu aad ayey uga duwan tahay tan matrix resin-ka, waxayna sidoo kale yeelan doontaa waxqabadyo kala duwan ee deegaan kala duwan iyo deegaan codsi oo kala duwan.Tusaale ahaan, alaabooyinka fiber carbon-ku-salaysan ee caadiga ah waxay leeyihiin waxqabad iska caabin ah oo aad u wanaagsan, waxayna yeelan karaan waxqabadka iska caabinta daxalka ee deegaanno kala duwan, iyo caabbinta guud ee cimiladu waa mid aad u wanaagsan, laakiin haddii ay ku jirto aagga cimilada kulul iyo qoyan, marka la barbardhigo. deegaanka gudaha, si degdeg ah ayay u gabowmi doontaa.Marka lagu daro isticmaalka maalinlaha ah ee alaabta fiber carbon, hoos fallaaraha qorraxda iyo codsiga guud ee fallaadhaha ultraviolet, daxalka inta badan wuxuu ka bilaabmaa daxalka dusha sare.Marka aan soo saarno badeecooyinka fiber-ka dheer, si aan si wanaagsan u hubinno adkeysiga iska caabbinta daxalka, badanaa waxay ka dhigan tahay in dusha sare lagu daaweeyay saliid oo lagu dahaadhay rinji hufan, taas oo si fiican u xaqiijin karta iska caabbinta daxalka ee alaabta fiber carbon.
Si loo hubiyo in si fiican loo hubiyo caabbinta daxalka ee alaabta fiber-ka, tirada qalabka matrixka ayaa inta badan ah in la doorto resins leh qaabab macromolecular oo ka kooban qaab-dhismeedka jirka, siddooyinka benzene, iyo heterocycles, iyo polymers crystalline sonkorta hydrogen ayaa laga samayn karaa inta u dhaxaysa molecules.Matrix-ku waa doorasho wanaagsan oo loogu talagalay kor u qaadista iska caabbinta daxalka ee alaabooyinka ka kooban fiber carbon.Codsiyada wax ku oolka ah, isdhexgalka u dhexeeya resin iyo fiber carbon sidoo kale waa qodob muhiim ah oo saameeya daxalka, sidaas darteed dahaarka alaabada fiber carbon waxay sidoo kale si wax ku ool ah u wanaajin kartaa caabbinta daxalka oo ay iska ilaaliso faragelinta qoyaanka ama warbaahinta waxyeelada leh.
Intaa waxaa dheer, inta lagu guda jiro habka wax soo saarka ee alaabta fiber carbon, waxaan sidoo kale fiiro gaar ah si ay porosity ama cilladaha qaab-dhismeedka, oo ay ku jiraan daaweynta compaction, taas oo ka dhigi kara lays ee walxaha daxalka ka mid ah faafin, taas oo sidoo kale waa daaweyn muhiim u ah saarayaasha our si loo hagaajiyo iska caabin daxalka ee alaabta fiber carbon.Jidka
Guud ahaan, iska caabinta daxalka eefiber carbonwaa mid aad u wanaagsan.Kadibna waxaan sheegayaa in guud ahaan caabbinta daxalka ee alaabada fiber-ka ay la xiriirto maaddada aasaasiga ah oo ay ku jiraan habka wax soo saarka iyo wax-soo-saarka dhabta ah.Haddii ay jiraan shuruudo loogu talagalay iska caabbinta daxalka ee alaabta fiber carbon, Waxaa lagama maarmaan ah in la helo wax soo saarka fiber carbon tayo sare leh, si si fiican loo hubiyo in shuruudaha iska caabin daxalka ee alaabta fiber carbon.
