Cov pa roj carbon fiber ntau muaj lub zog tshwj xeeb, siab tshwj xeeb modulus, qaug zog tiv thaiv, corrosion kuj thiab lwm yam khoom zoo heev, dav siv hauv aerospace, kev lag luam tub rog, khoom siv ua kis las thiab lwm yam haujlwm. Carbon fiber reinforced polymerization

Cov pa roj carbon fiber ntau muaj lub zog tshwj xeeb, siab tshwj xeeb modulus, qaug zog tiv thaiv, corrosion kuj thiab lwm yam khoom zoo heev, dav siv hauv aerospace, kev lag luam tub rog, khoom siv ua kis las thiab lwm yam haujlwm. Cov khoom siv kho tshuab ntawm carbon fiber reinforced polymer matrix composites feem ntau yog nyob ntawm cov khoom sib txuas ntawm carbon fiber thiab matrix. Txawm li cas los xij, qhov du ntawm carbon fiber, siab lub siab lub ntsws thiab ob peb cov tshuaj nquag ua haujlwm pab pawg ua rau tsis muaj zog cuam tshuam kev sib raug zoo ntawm carbon fiber thiab matrix resin, thiab theem cuam tshuam feem ntau yog qhov tsis muaj zog ntawm cov khoom sib xyaw. Lub interfacial microstructure ntawm carbon fiber composites yog ze ze rau lub interfacial zog. Qhov polarity ntawm cov pa roj carbon fiber ntau nyob rau hauv qhov chaw morphology ntawm carbon fiber thiab hom tshuaj lom neeg ua haujlwm. Ob qho kev nce ntawm cov pab pawg nquag thiab nce ntawm roughness ntawm carbon fiber nto yog qhov tsim nyog rau kev nce ntawm cov pa roj carbon fiber ntau zog. Cov khoom siv ntawm lub cev ntawm cov pa roj carbon fiber ntau muaj xws li nto morphology, nto zawj loj thiab kev faib tawm, nto roughness, deg dawb zog thiab lwm yam. Nyob rau hauv cov nqe lus ntawm morphology nto, muaj ntau qhov pores, grooves, impurities thiab muaju nyob rau saum npoo ntawm carbon fiber, uas muaj kev cuam tshuam zoo rau cov khoom sib txuas ntawm cov khoom sib xyaw. Cov tshuaj reactivity ntawm carbon fiber nto yog ze ze rau lub concentration ntawm active pab pawg neeg, thiab cov active pab pawg neeg no mas yog cov pa oxygen uas muaj functional pab pawg xws li lub teeb pab pawg neeg, spindle pawg thiab epoxy pawg. Tus naj npawb ntawm cov pab pawg ua haujlwm nyob rau saum npoo ntawm carbon fiber nyob ntawm qhov chaw electrochemical kev kho mob thiab cov degree lossis kub ntawm fiber ntau carbonization. Piv txwv li, kev kho cov kua qaub yuav muab cov fiber ntau ua haujlwm ntau dua li kev kho alkali, thiab rau tib txoj kev kho mob, qhov kub ntawm carbonization ntau dua, cov pab pawg ua haujlwm tsawg dua. Tsawg modulus carbon fiber feem ntau muaj ntau pawg ua haujlwm vim nws cov qib qis ntawm carbonization, yog li nws yuav hnov ​​​​mob nrog epoxy pawg hauv kev npaj ntawm epoxy matrix composites, thaum cov tshuaj tiv thaiv ntawm siab modulus carbon fiber system yuav tsis quav ntsej, thiab cov fiber ntau thiab resin. feem ntau muaj kev cuam tshuam tsis muaj zog. Ntau cov kev tshawb fawb tau pom tias cov khoom sib txuas ntawm cov khoom sib txuas tuaj yeem txhim kho tau zoo los ntawm kev hloov kho qhov sib txuas microstructure ntawm cov khoom sib txuas los ntawm kev hloov kho ntawm cov pa roj carbon fiber ntau, uas yog ib qho ntawm cov kev tshawb fawb hotspots hauv thaj chaw ntawm carbon fiber cladding cov ntaub ntawv.
