1. Kusimba simba
Tensile simba ndiyo yakanyanya kudzvinyirira chinhu chinogona kumira pamberi pekutambanudza. Zvimwe zvisiri-brittle zvinhu zvinokanganisa zvisati zvaputika, asiKevlar® (aramid) fibers, carbon fibers, uye maE-glass fibers haana kusimba uye anotsemuka pasina kushanduka. Kusimba kwesimba kunoyerwa sesimba pachikamu chimwe nechimwe (Pa kana Pascals).

2. Density uye Simba-ku-Weight Ratio
Kana tichienzanisa kusimba kwezvinhu zvitatu, misiyano yakakura mumafibhi matatu inogona kuoneka. Kana masamples matatu ehukuru hwakafanana nehuremu akagadzirwa, zvinokurumidza kuoneka kuti Kevlar® fibers yakareruka, ine carbon fibers sekondi iri pedyo uye.E-girazi fibersyakanyanya kurema.

3. Young's Modulus
Young's modulus chiyero chekuomarara kwechinhu chinonamira uye inzira yekutsanangura chinhu. Inotsanangurwa seyero ye uniaxial (mune imwe nzira) kushushikana kune uniaxial strain (deformation munzira imwechete). Young's modulus = stress/strain, zvinoreva kuti zvinhu zvine high Young's modulus yakaoma pane izvo zvine low Young's modulus.
Iko kuoma kwekabhoni fiber, Kevlar®, uye girazi fiber inosiyana zvakanyanya. Carbon faibha yakaoma zvakapetwa kaviri semaaramidhi fiber uye kashanu kuomarara kupfuura magirazi faibha. Iyo yakaderera yekuomarara kwekabhoni fiber ndeyekuti inowanzoita brittle. Kana ikakundikana, inoita kuti isaratidze kuomarara kana deformation.

4. Kupisa uye kuora kwekupisa
Kevlar® uye kabhoni fiber inoshingirira kune tembiricha yakakwira, uye haina nzvimbo yekunyungudika. Zvinhu zvose zviri zviviri zvakashandiswa muzvipfeko zvinodzivirira uye machira asingadziviriri moto. Fiberglass inozonyungudika, asi zvakare inopikisa zvakanyanya kune tembiricha yakakwira. Ehe, firosted girazi fibers anoshandiswa muzvivakwa anogonawo kuwedzera moto kuramba.
Carbon fiber uye Kevlar® inoshandiswa kugadzira moto wekudzivirira kana welding magumbeze kana zvipfeko. kevlar magirovhosi anowanzoshandiswa muindasitiri yenyama kudzivirira maoko kana uchishandisa mapanga. Sezvo iyo fiber isingawanzo shandiswa pachayo, kupikisa kupisa kwematrix (kazhinji epoxy) kunokosha zvakare. Kana ichipisa, epoxy resin inopfava nekukurumidza.

5. Electrical Conductivity
Carbon fiber inoitisa magetsi, asi Kevlar® uyefiberglassusadaro.Kevlar® inoshandiswa kudhonza waya munhare dzekutumira. Kunyangwe isingaite magetsi, inotora mvura uye mvura inoita magetsi. Naizvozvo, jira rekusapinda mvura rinofanira kuiswa kuna Kevlar mukushandisa kwakadaro.

6. Kusvibiswa kweUV
Aramid fibersichadzikisira muchiedza chezuva uye yakakwirira UV nharaunda. Carbon kana girazi fibers haanyanyi kutarisisa kune UV mwaranzi. Nekudaro, mamwe matrices akajairwa senge epoxy resin anochengetwa muchiedza chezuva uko anozochena uye kupera simba. Polyester uye vinyl ester resins inonyanya kurwisa UV, asi haina kusimba pane epoxy resins.

7. Kuramba kuneta
Kana chikamu chikaramba chakakotama uye chichitwasuka, chinozopedzisira chakundikana nekuda kwekuneta.Carbon fiberinonzwa kuneta uye inotadza kukundikana, nepo Kevlar® isingachinji kuneta. Fiberglass pane imwe nzvimbo pakati.

8. Abrasion kuramba
Kevlar® inopesana zvakanyanya neabrasion, izvo zvinoita kuti zviome kucheka, uye imwe yezvinowanzoshandiswa Kevlar® yakaita semagirovhosi ekudzivirira kunzvimbo uko maoko anogona kutemwa negirazi kana uko kunoshandiswa mapanga akapinza. Carbon uye magirazi fibers haanyanyi kushingirira.

9. Chemical resistance
Aramid fibersinonzwa kune yakasimba acids, mabhesi uye mamwe maoxidizing agents (semuenzaniso, sodium hypochlorite), izvo zvinogona kukonzera kuparara kwefiber. Chlorine bleach (seClorox®) nehydrogen peroxide haigoni kushandiswa neKevlar®. Oxygen bleach (eg sodium perborate) inogona kushandiswa pasina kukuvadza aramid fibers.

10. Body bonding properties
Kuti kabhoni fibers, Kevlar® uye girazi riite zvakakwana, zvinofanirwa kubatwa munzvimbo mumatrix (kazhinji epoxy resin). Naizvozvo, kugona kweiyo epoxy kusungirira kune akasiyana mafiber kwakakosha.
Zvose kabhoni uyegirazi fibersinogona kunamatira nyore kune epoxy, asi iyo aramid fiber-epoxy bond haina kusimba sezvainoda, uye iyi yakaderedzwa kunamatira inobvumira kupinda kwemvura kuitika. Somugumisiro, iyo yakasununguka iyo aramid fibers inogona kutora mvura, yakasanganiswa nekunamatira kusingadikanwi kune epoxy, zvinoreva kuti kana pamusoro pekevlar® composite yakakuvadzwa uye mvura inogona kupinda, ipapo Kevlar® inogona kutora mvura pamwe chete nefibers uye iite simba rekubatanidza.

11. Ruvara uye weave
Aramid igoridhe rakareruka mumamiriro ayo echisikigo, inogona kuve neruvara uye ikozvino inouya mune akawanda akanaka mimvuri. Fiberglass inouyawo mumhando dzemavara.Carbon fiberinogara yakasviba uye inogona kusanganiswa nemavara aramid, asi haigone kuve neruvara pachayo.
