1. Ka ikaika tensile
ʻO ka ikaika tensile ke koʻikoʻi kiʻekiʻe loa e hiki ai i kahi mea ke kū ma mua o ke kikoo ʻana. Deform kekahi mau mea non-brittle ma mua o ka haki ʻana, akāNā laula Kevlar® (aramid)., nā pulupulu kalapona, a me nā kīʻaha E-aniani he palupalu a nahae me ka liʻiliʻi liʻiliʻi. Ua ana ʻia ka ikaika tensile e like me ka ikaika o kēlā me kēia ʻāpana (Pa a i ʻole Pascals).

2. ʻAiʻi a me ka ikaika-a-kaumaha
I ka hoʻohālikelike ʻana i nā mānoanoa o nā mea ʻekolu, ʻike ʻia nā ʻokoʻa koʻikoʻi o nā fibers ʻekolu. Inā hana ʻia ʻekolu mau laʻana like ʻole ka nui a me ke kaumaha, ʻike koke ʻia ʻoi aku ka māmā o nā fibers Kevlar®, me nā fiber carbon i kekona kokoke aNā puluna aniani Eka mea kaumaha loa.

3. Opio Modulus
ʻO ka modulus o Young kahi ana o ka ʻoʻoleʻa o kahi mea elastic a he ala ia e wehewehe ai i kahi mea. Ua wehewehe ʻia ʻo ia ka ratio o ka uniaxial (ma ka ʻaoʻao hoʻokahi) koʻikoʻi i ke koʻikoʻi uniaxial (deformation ma ka ʻaoʻao like). 'Ōpio modulus = ko'iko'i/koi, 'o ia ho'i, 'oi aku ka 'o'ole'a o nā mea me ka modulus 'Opio ki'eki'e ma mua o nā mea me ka modulus Young ha'aha'a.
ʻOkoʻa ka ʻoʻoleʻa o ka fiber carbon, Kevlar®, a me ke aniani aniani. ʻOi aku ka ʻoi aku o ka ʻoi aku o ka ʻoʻoleʻa ma mua o nā fila aramid a ʻelima manawa ʻoi aku ka paʻakikī ma mua o nā fiber aniani. ʻO ka ʻaoʻao haʻahaʻa o ka ʻoʻoleʻa maikaʻi o ka fiber carbon, ʻoi aku ka palupalu. Ke hāʻule ʻole, ʻaʻole ia e hōʻike i ke koʻikoʻi nui a i ʻole deformation.

4. ʻO ke ahi a me ka hoʻohaʻahaʻa wela
Paʻa ʻelua Kevlar® a me ka fiber carbon i nā wela kiʻekiʻe, a ʻaʻohe wahi heheʻe. Ua hoʻohanaʻia nā meaʻelua i nā lole pale a me nā lole pale ahi. E hehee hope loa ka Fiberglass, akā ua kūpaʻa loa i nā wela kiʻekiʻe. ʻOiaʻiʻo, hiki ke hoʻonui i ke kūpaʻa ahi i nā fibers aniani hau i hoʻohana ʻia i nā hale.
Hoʻohana ʻia ka carbon fiber a me Kevlar® no ka hana ʻana i nā pale pale ahi a i ʻole nā ​​pale pale a i ʻole nā lole. Hoʻohana pinepine ʻia nā mīkina lima kevlar i ka ʻoihana ʻiʻo e pale i nā lima i ka wā e hoʻohana ai i nā pahi. No ka mea ʻaʻole hoʻohana ʻia nā fibers iā lākou iho, he mea nui hoʻi ka pale wela o ka matrix (maʻamau epoxy). Ke hoʻomehana ʻia, palupalu koke ka epoxy resin.

5. Uila Conductivity
ʻO ka fiber carbon ke alakaʻi i ka uila, akā ʻo Kevlar® a meaniani uilaʻaʻole. Hoʻohana ʻia ʻo Kevlar® no ka huki ʻana i nā uea i nā hale kiaʻi hoʻouna. ʻOiai ʻaʻole ia e hoʻokele i ka uila, hoʻopaʻa ʻo ia i ka wai a hoʻokele ka wai i ka uila. No laila, pono e hoʻopili ʻia kahi uhi wai iā Kevlar i ia mau noi.

6. Hoʻohaʻahaʻa UV
ʻO nā fiber Aramide hoʻohaʻahaʻa i ka lā a me nā wahi UV kiʻekiʻe. ʻAʻole paʻakikī loa ka kalapona a i ʻole ke aniani aniani i ka radiation UV. Eia nō naʻe, mālama ʻia kekahi mau matrices maʻamau e like me ka epoxy resins i ka lā kahi e keʻokeʻo ai a nalowale ka ikaika. ʻOi aku ka pale ʻana o ka polyester a me ka vinyl ester resins i UV, akā nāwaliwali ma mua o nā resins epoxy.

7. Ke kū'ē i ka luhi
Inā piʻo pinepine a hoʻopololei ʻia kekahi ʻāpana, e hāʻule ana ma muli o ka luhi.Kāpena kalaponaʻano maʻalahi i ka luhi a makemake e hāʻule i ka pōʻino, ʻoiai ʻo Kevlar® ʻoi aku ka pale ʻana i ka luhi. Aia ka Fiberglass ma waena.

8. Kūʻē abrasion
ʻO ka Kevlar® ka mea paʻakikī i ka abrasion, he mea paʻakikī ke ʻokiʻoki, a ʻo kekahi o ka hoʻohana maʻamau o Kevlar® he mau mīkina lima pale no nā wahi e ʻoki ʻia ai nā lima e ke aniani a i ʻole kahi e hoʻohana ʻia ai nā pahi ʻoi. ʻAʻole kū kūʻē ke kalapona a me ke aniani.

9. Ke kū'ē kemika
ʻO nā fiber Aramidpaʻakikī i nā ʻakika ikaika, nā kumu a me kekahi mau mea hoʻoheheʻe (e laʻa, ka sodium hypochlorite), hiki ke hōʻemi i ka fiber. ʻAʻole hiki ke hoʻohana ʻia ka wai holoi chlorine maʻamau (e laʻa me Clorox®) a me ka hydrogen peroxide me Kevlar®. Hiki ke hoʻohana ʻia ka bleach oxygen (e laʻa me ka sodium perborate) me ka ʻole o ka hōʻino ʻana i nā fiber aramid.

10. Nā waiwai pili kino
I mea e hana maikaʻi ai nā fiber carbon, Kevlar® a me ke aniani, pono e hoʻopaʻa ʻia lākou ma kahi o ka matrix (maʻamau he epoxy resin). No laila, he mea koʻikoʻi ka hiki ʻana o ka epoxy e hoʻopaʻa i nā fiber like ʻole.
ʻO ke kalapona a me kakīʻaha anianihiki ke hoʻopili maʻalahi i ka epoxy, akā ʻaʻole ikaika ka paʻa aramid fiber-epoxy e like me ka makemake, a ʻo kēia hoʻemi ʻana i hiki ke komo i ka wai. ʻO ka hopena, ʻo ka maʻalahi o ka hiki ʻana i nā fila aramid ke komo i ka wai, i hui pū ʻia me ka adhesion makemake ʻole ʻia i ka epoxy, ʻo ia hoʻi, inā e pōʻino ka ʻili o ke kevlar® composite a komo ka wai, a laila hiki iā Kevlar® ke komo i ka wai ma nā fibers a hoʻonāwaliwali i ka composite.

11. Kala a ulana
He gula māmā ʻo Aramid i kona ʻano kūlohelohe, hiki ke kala ʻia a hiki mai kēia manawa i nā aka nani he nui. Hele mai ʻo Fiberglass i nā ʻano kala.Kāpena kalaponaʻeleʻele mau a hiki ke hoʻohui ʻia me ka aramid kala, akā ʻaʻole hiki ke kala iā ia iho.
