1. Simba reConsile
Simba reChile ndiko kushushikana kwakanyanya zvinhu zvinogona kutsungirira usati watambanudza. Zvimwe zvisiri-brittle zvinhu deform usati wabvarura, asiKevar® (Aramid) Fibers, carbon fils, uye e-girazi machira asina kusimba uye kuputika nekushoma deformation. Simba resimba rinoyerwa seanomanikidza pane yuniti nzvimbo (PA kana maascals).

2. Density uye simba-kune-uremu chiyero
Paunenge uchienzanisa densities dzezvimwe zvinhu zvitatu, kusiyana kwakakosha mumachira matatu kunogona kuonekwa. Kana matatu samples yeiyo chaiyo saizi uye uremu hwakaitwa, zvinokurumidza kuoneka kuti Kevlar® fibers akawanda akareruka, aine carbon fibers yechipiri uyeE-Girazi Flaberszvinorema.

3. Young Modulus
Vechidiki's Modulus chiyero chekusimudzwa kwechinhu chakashama uye inzira yekutsanangura zvinhu. Izvo zvinotsanangurwa seyero yeCariial (mune imwe nzira) kushushikana kune undiaxial train (deformation nenzira imwechete). Mudiki's Modugus = kushushikana / kushushikana, zvinoreva kuti zvigadzirwa zvine mwero wechidiki wepamusoro pane zvinyoro-nyoro pane izvo zvine mwero wechidiki akaderera.
Kuomarara kweCarbon fiber, Kevlar®, uye girazi fiber inosiyana zvakanyanya. Carbon fiber inenge yakapetwa kaviri seyakaomarara seyakarongedzwa machira uye kashanu stiffofi kupfuura girazi. Iyo madhiri ecarbon fiber inomutsa kuomarara ndeyekuti inowanzoita kuti iite brittle. Kana ikatadza, inokoshesa kusaratidza kutambudzika kwakawanda kana kusvibiswa.

4. Kuchiva uye kupisa kusvibiswa
Ose kevlar® uye kabhoni fiber inodzivirira kupisa kwakanyanya, uye isina poindi yekunyungudika. Zvese zvinhu zvave zvichishandiswa mukupfeka zvipfeko zvinodzivirira uye machira anodzivirira moto. Fiberglass ichanyungudika, asi zvakare inodzivirira zvakanyanya kupisa. Ehe, machira egirazi egirazi anoshandiswa muzvivakwa anogona zvakare kuwedzera kudzivisa moto.
Carbon fiber uye kevlar® inoshandiswa kugadzira kudzima moto kana magumbeze kana zvipfeko. Magurovhosi eKevar anowanzo shandiswa muindasitiri yehusiku kuti vadzivirire maoko kana vachishandisa mapanga. Sezvo mafambi asingawanzo kushandiswa ari oga, kupokana kwekupisa kwematrix (kazhinji epoxy) kunokoshawo. Kana ichipiswa, epoxy resin inofarira nekukurumidza.

5. Magetsi unoridza
Carbon fiber inoitisa magetsi, asi Kevar® uyefiberglassUNE.Kovar® inoshandiswa pakudhonza waya mune shongwe dzeshongwe. Kunyangwe iyo isingaitise magetsi, inobata mvura nemvura inoita magetsi. Naizvozvo, kubhururuka kwemvura kunofanira kuiswa ku kevlar mune dzakadaro mashandisiro.

6. UV kusvibiswa
Maramisiichashatisa muchiedza chezuva uye yakakwira UV nharaunda. Kabhoni kana girazi machira haana kunyatsonaka kuUV radiation. Nekudaro, mamwe matrices akajairwa senge epoxy resins anochengetwa muchiedza chezuva apo ichachena uye kurasikirwa nesimba. Polyester uye vinyl ester enesins anodzivisa kuUv, asi asina simba pane ipoxy resins.

7. Kuneta kuramba
Kana chikamu chakadzokororwa chakakotama uye chakatwasuka, chichazokundikana nekuda kwekuneta.Carbon fiberInoshamisa inonzwira tsitsi kuneta uye inowanzo kutadza njodzi, nepo kevlar® iri kuramba ichiramba kupera simba. Fiberglass pane imwe nzvimbo pakati.

8. Abrasion Kudzivisa
Kevar® inodzivirira zvakanyanya kune abrasion, iyo inoita kuti zviome kucheka, uye chimwe chezvakajairika zve kevara Kabhoni uye girazi machira haakanganisike.

9. Kemical Resistance
Maramisiane hanya neakasimba acids, zvigadziko uye zvimwe zvevamwe oxidizing vamiririri (semuenzaniso, sodium hypochlorite), iyo inogona kukonzera kusvibiswa kwe fiber. Yakajairika chlorine breach (eg clorox®) uye hydrogen peroxide haigone kushandiswa ne kevlar®. Oxygen bleach (semuenzaniso sodium inopararira) inogona kushandiswa pasina kukuvadza maramisi emitambo.

10. Kubatanidza muviri zviumbwa
Kuitira carbon fils, kevlar® uye girazi kuita optarilly, ivo vanofanirwa kuitirwa munzvimbo mumatrix (kazhinji epoxy resin). Naizvozvo, kugona kweiyo epoxy kusunga kune iyo dzakasiyana-siyana mafuru anokosha.
Zvese kabhoni uyegirazi machiraInogona kuomerera nyore nyore kune epoxy, asi iyo Aramid fiber-epoxy bond haina kusimba sezvinodiwa, uye izvi zvakaderedzwa kuderedza kunobvumira kupinda kwemvura kuti zviitike. Nekuda kweizvozvo, kusununguka uko varwi vechirume vanogona kutora mvura, vanoreva kuti kana pamusoro peiyo Kevlar® inokuvara uye mvura inogona kupinda, ipapo Kevar® inogona kutora mvura pamwe chete nemuchina uye nekudzora manyorerwo.

11. Ruvara uye weave
Aramidhi idanzuru yegoridhe mumamiriro ayo echisikigo, inogona kuve ine mavara uye ikozvino yasvika mumamita mazhinji akanaka. Fiberglass zvakare inouya mumavhesi mavara.Carbon fiberinogara yakasviba uye inogona kusanganiswa neramid yemavara, asi haigone kuverengerwa.
