1. Matla a tsitsitseng
Matla a matla ke khatello e phahameng ka ho fetisisa eo thepa e ka e mamellang pele e otlolla. Lisebelisoa tse ling tse sa brittle li holofala pele li phatloha, empaKevlar® (aramid) likhoele, likhoele tsa k'habone, le likhoele tsa E-glass li senyeha habonolo 'me lia phunyeha 'me ha li fetohe. Matla a matla a lekanngoa e le matla ka sebaka sa yuniti (Pa kapa Pascals).

2. Tekanyo ea Boima le Matla-to-Boima
Ha ho bapisoa ho teteana ha lisebelisoa tse tharo, ho ka bonoa phapang e kholo ho likhoele tse tharo. Haeba ho etsoa lisampole tse tharo tsa boholo le boima bo lekanang hantle, ho tla bonahala kapele hore likhoele tsa Kevlar® li bobebe haholo, 'me likhoele tsa carbon li haufi ka motsotsoana.Likhoele tsa e-glasse boima ka ho fetisisa.

3. Modulus ea Bacha
Young's modulus ke tekanyo ea ho satalla ha lesela le rekere 'me ke mokhoa oa ho hlalosa thepa. E hlalosoa e le karo-karolelano ea uniaxial (ka lehlakoreng le le leng) khatello ea kelello ho uniaxial strain (deformation ka tsela e le 'ngoe). Young's modulus = khatello ea maikutlo / khatello, ho bolelang hore lisebelisoa tse nang le modulus e phahameng ea Young li thata ho feta tse nang le modulus e tlaase ea Young.
Ho satalla ha carbon fiber, Kevlar®, le fiber ea khalase ho fapana haholo. Fiber ea carbon e thata ho feta likhoele tsa aramid le makhetlo a mahlano ho feta likhoele tsa khalase. Taba e mpe ea ho satalla ho hoholo ha carbon fiber ke hore e atisa ho ba brittle haholoanyane. Ha e hloleha, hangata ha e bontše khatello e ngata kapa deformation.

4. Ho chesa le ho senyeha ha mocheso
Ka bobeli Kevlar® le carbon fiber li hanana le mocheso o phahameng, 'me ha li na sebaka se qhibilihang. Lisebelisoa tsena ka bobeli li sebelisitsoe liaparo tse sireletsang le masela a sa cheng. Fiberglass qetellong e tla qhibiliha, empa hape e hanyetsana haholo le mocheso o phahameng. Ha e le hantle, likhoele tsa khalase tse nang le serame tse sebelisoang mehahong li ka boela tsa eketsa ho hanyetsa mollo.
Carbon fiber le Kevlar® li sebelisetsoa ho etsa litima-mollo tse sireletsang kapa likobo kapa liaparo tsa ho cheseletsa. Hangata li-gloves tsa kevlar li sebelisoa indastering ea nama ho sireletsa matsoho ha ho sebelisoa lithipa. Kaha likhoele ha li sebelisoe hangata ka botsona, ho hanyetsa mocheso oa matrix (hangata epoxy) ho bohlokoa hape. Ha e chesa, epoxy resin e nolofala ka potlako.

5. Motlakase Conductivity
Carbon fiber e tsamaisa motlakase, empa Kevlar® lefiberglassu se ke ua.Kevlar® e sebelisoa bakeng sa ho hula lithapo litorang tsa phetiso. Leha e sa tsamaise motlakase, e monya metsi mme metsi a tsamaisa motlakase. Ka hona, ho tlameha ho kenngoe lesela le sa keneleng metsi ho Kevlar lits'ebetsong tse joalo.

6. Ho senyeha ha UV
Likhoele tsa Aramide tla senya khanya ea letsatsi le tikoloho e phahameng ea UV. Lithapo tsa carbon kapa tsa khalase ha li utloe haholo mahlaseling a kotsi a UV. Leha ho le joalo, matrices a mang a tloaelehileng a kang li-epoxy resin li bolokiloe letsatsing moo li tla soeufala le ho felloa ke matla. Li-resin tsa polyester le vinyl ester li hanyetsa UV, empa li fokola ho feta li-epoxy resin.

7. Ho hanyetsa mokhathala
Haeba karolo e kobeha khafetsa le ho otloloha, qetellong e tla hlōleha ka lebaka la mokhathala.Fiber ea carbone batla e utloa mokhathala 'me e na le tšekamelo ea ho hlōleha habohloko, athe Kevlar® eona e mamella mokhathala haholoanyane. Fiberglass e kae-kae lipakeng.

8. Ho hanyetsa abrasion
Kevlar® e hanyetsana haholo le abrasion, e leng se etsang hore ho be thata ho seha, 'me e' ngoe ea lintho tse tloaelehileng tse sebelisoang ke Kevlar® ke li-gloves tse sireletsang libakeng tseo matsoho a ka sehoang ka khalase kapa moo ho sebelisoang mahare a bohale. Likhoele tsa carbon le tsa khalase ha li khone ho mamella.

9. Ho hanyetsa lik'hemik'hale
Likhoele tsa Aramidli na le kutloelo-bohloko ho li-acid tse matla, li-bases le li-oxidizing agents (mohlala, hypochlorite ea sodium), e ka bakang ho senyeha ha fiber. Bleach e tloaelehileng ea chlorine (mohlala, Clorox®) le hydrogen peroxide e ke ke ea sebelisoa le Kevlar®. Oxygen bleach (mohlala, sodium perborate) e ka sebelisoa ntle le ho senya likhoele tsa aramid.

10. Thepa ea tlamahano ea 'mele
E le hore likhoele tsa carbon, Kevlar® le khalase li sebetse hantle, li tlameha ho tšoaroa sebakeng sa matrix (hangata epoxy resin). Ka hona, bokhoni ba epoxy ho ikopanya le likhoele tse fapaneng bo bohlokoa.
Ka bobeli carbon lelikhoele tsa khalasee ka khomarela habonolo ho epoxy, empa tlamo ea fiber-epoxy ea aramid ha e matla kamoo e lakatsoang kateng, 'me ho fokotseha hona ho fokotsa ho lumella ho kenella ha metsi ho etsahala. Ka lebaka leo, boiketlo ba hore likhoele tsa aramid li ka monya metsi, li kopantsoe le ho khomarela ho sa rateheng ho epoxy, ho bolela hore haeba bokaholimo ba motsoako oa kevlar® bo senyehile mme metsi a ka kena, joale Kevlar® e ka monya metsi haufi le likhoele mme ea fokolisa. motsoako.

11. Mmala le ho loha
Aramid ke khauta e bobebe boemong ba eona ba tlhaho, e ka ba mebala 'me joale e tla ka mebala e mengata e metle. Fiberglass e boetse e tla ka mefuta e mebala.Fiber ea carbone lula e le ntšo 'me e ka kopanngoa le aramid e mebala, empa e ke ke ea mebala ka boeona.
