Kev kho mob ntshav plasma yog ib txoj kev hloov kho uas tau nyiam cov neeg tshawb nrhiav ntau heev. Plasma yog ib qho sib xyaw ionized uas muaj ions, electrons, dawb radicals, thiab zoo siab molecules thiab atoms, uas cuam tshuam nrog fiber ntau nto los tsim cov tshuaj reactive heev. Nyob ntawm cov khoom siv roj, cov dawb radicals, ions, thiab cov tshuaj metastable yuav raug tsim, pib ablation, hla -txuas, lossis oxidation tshwm sim. Cov pa roj ntsha uas siv los tsim cov ntshav muaj xws li huab cua, O2, NH3, N2, thiab Ar.
Thaum cov txheej txheem kho ntshav plasma, cov ntshav plasma etches thiab hloov cov morphology ntawm cov fiber ntau, yog li ua rau nws roughness. Oxidation tsim cov pa oxygen- muaj cov pab pawg ua haujlwm, ua kom cov haujlwm ntawm fiber ntau. Qhov no txhim kho lub cev intercalation thiab tshuaj sib txuas ntawm fiber ntau thiab polymer, ntxiv dag zog rau kev sib txuas ntawm lub ntsej muag. Kev siv cov ntshav me me los kho cov ntaub ntawv muaj ob qhov zoo: ua ntej, nws tuaj yeem siv rau hauv txhua qhov chaw, xws li inert, txo, lossis oxidizing atmospheres; Thib ob, cov tshuaj tiv thaiv tsuas yog tshwm sim ntawm cov khoom siv nto thiab tsis cuam tshuam rau tag nrho cov khoom. Txoj kev kho no yooj yim rau kev khiav lag luam, muaj txiaj ntsig zoo, ua rau muaj kev puas tsuaj tsawg rau cov fiber ntau, thiab tsis tas yuav tsum tau kho tom ntej. Txawm li cas los xij, nws muaj lub sij hawm-sensitive nature; cov pa roj carbon fibers kho hauv plasma yuav tsum tau sib xyaw nrog cov polymer matrix sai li sai tau.
