PTFE ke polasetiki e nang le fluorine, e tsejoang hape e le Teflon, Teflon, joalo-joalo.PTFE polasetikie boetse e tsejoa e le Morena oa Plastiki ka lebaka la ts'ebetso ea eona e phahameng likarolong tsohle.PTFE e ka hanela kutu, mocheso o phahameng le o tlase, ha e chefo, ha e na chefo, ha e na chefo e ntle haholo, e thibela ho tsofala, ho tlotsa haholo, le lisebelisoa tse ling tse ntle haholo.Leha ho le joalo, ho na le lintho tse ngata tse lokelang ho ntlafatsoa, tse kang ho kheloha, ho se thupeng, ho hanyetsa abrasion, ho ruruha ha line le khatello ea khatello, ho thatafala joalo-joalo.E le ho ntlafatsa ka ho eketsehileng thepa ena ea PTFE, lintho tse ling tse kang molybdenum disulfide, fiber ea khalase, graphite, resin ea polyphenylene, fiber ea khalase le phofo ea tšepe li ka ekeletsoa lihlahisoa tse tala tsa PTFE ka tekanyo.Ho phaella ha carbon fibers ke mokhoa o tloaelehileng oa ho fetola lihlahisoa tsa PTFE.Karolo ea li-fiber tsa carbon ho tlatsa PTFE ke ho eketsa khanyetso ea creep, ho hanyetsa moroalo, ho hanyetsa ho roala, botsitso ba sebopeho, matla a thata le lisebelisoa tse ling tsaPTFE e sebelisa.
Carbon fiber (CF for short) ke mofuta o mocha oa fiber e nang le matla a holimo le modulus e phahameng e nang le carbon e fetang 95%.Ke microcrystalline graphite material e entsoeng ka likhoele tsa tlhaho tse kang flake graphite microcrystals tse khomaretsoeng ka lehlakoreng la axial la likhoele, tse sebetsoang ke carbonization le graphitization.Carbon fiber "e bonolo ka ntle empa e tiile ka hare", e bobebe ka boima ho feta aluminium empa e matla ho feta tšepe, 'me e na le litšobotsi tsa ho hanyetsa kutu le modulus e phahameng, e leng se etsang hore e be thepa ea bohlokoa ts'ebetsong ea ts'ireletso le ea sechaba.Ha e na feela litšobotsi tsa tlhaho tsa tlhaho ea lisebelisoa tsa carbon empa hape e na le bonolo le ts'ebetso ea likhoele tsa masela, e leng se etsang hore e be moloko o mocha oa likhoele tse matlafatsang.Carbon fiber e na le lintho tse ngata tse ntle haholo.E na le matla a phahameng a axial le modulus, ha e na ho thella, ho hanyetsa mokhathala o motle, mocheso o khethehileng le conductivity ea motlakase pakeng tsa li-non-metal le tšepe, le tšireletso e ntle ea motlakase.Coefficient ea katoloso ea mocheso e nyane, khanyetso ea kutu e ntle, letsoalo la likhoele li tlase, ho kenella ha X-ray ho lokile, boima bo bobebe, 'me tikoloho e senang oxidizing e hanana le mocheso o phahameng haholo.Ha ho bapisoa le likhoele tse tloaelehileng tsa khalase, fiber ea carbon e na le makhetlo a fetang a mararo modulus ea Young.Ha e bapisoa le Kevlar, Young's modulus e phahame ka makhetlo a mabeli, 'me ha e qhibilihe ebile e ruruha ka har'a metsoako ea organic, acid le alkalis,' me e na le khanyetso e tsotehang ea ho bola.Ho eketsoa ha carbon fiber ho ntlafatsa haholo matla a ho jara thepa ea motsoako, 'me palo e nyenyane ea graphite e kenngoa ka nako e le 'ngoe le PTFE hammoho le thepa ea ho tlatsa carbon fiber.Ho eketsoa ha graphite ho fokotsa khohlano pakeng tsa carbon fiber surface le molekane, kahoo ho fokotsa tšekamelo ea ho oa ha carbon fiber le ho ntlafatsa ho hanyetsa ho apara ha thepa e kopantsoeng.
