Loaʻa i ka carbon fiber ka ikaika kikoʻī kiʻekiʻe, ka modulus kikoʻī kiʻekiʻe, ka pale ʻana i ka luhi, ka pale ʻana i ka corrosion a me nā waiwai maikaʻi ʻē aʻe, hoʻohana nui ʻia i ka aerospace, ʻoihana koa, nā mea haʻuki a me nā kula ʻē aʻe. ʻO ka polymerization i hoʻoikaika ʻia ka fiber carbon

Loaʻa i ka carbon fiber ka ikaika kikoʻī kiʻekiʻe, ka modulus kikoʻī kiʻekiʻe, ka pale ʻana i ka luhi, ka pale ʻana i ka corrosion a me nā waiwai maikaʻi ʻē aʻe, hoʻohana nui ʻia i ka aerospace, ʻoihana koa, nā mea haʻuki a me nā kula ʻē aʻe. ʻO nā ʻano mechanical o ka carbon fiber reinforced polymer matrix composites e hilinaʻi nui ʻia i nā waiwai pili ma waena o ka carbon fiber a me ka matrix. Eia nō naʻe, ʻo ka maʻalahi o ka ʻili kalapona, nā ʻano manaʻo kiʻekiʻe a me nā pūʻulu hana hana kemika e hopena i ka nawaliwali o ka pilina ma waena o ka carbon fiber a me ka resin matrix, a ʻo ka pae interface ka loulou nāwaliwali o nā mea hana. ʻO ka microstructure interfacial o nā composite carbon fiber pili pili i nā waiwai interfacial. Aia ka polarity ili o ka fiber carbon i ka morphology o ka ʻili kalapona a me nā ʻano hui hana kemika. ʻO ka piʻi ʻana o nā pūʻulu ikaika a me ka piʻi ʻana o ka ʻinoʻino o ka ʻili o ka fiber carbon i mea e hoʻonui ai i ka ikehu ʻili o ka carbon fiber. ʻO nā waiwai kino o ka ʻili kalapona ka nui o ka morphology o ka ʻili, ka nui a me ka puʻunaue ʻana o ka ʻili, ka ʻili o ka ʻili, ka ikehu manuahi a me nā mea ʻē aʻe. Ma ke ʻano o ka morphology surface, he nui nā pores, grooves, haumia a me nā kristal ma ka ʻili o ke kalapona kalapona, he mea nui ka mana i nā waiwai paʻa o nā mea hoʻohui. ʻO ka hana kemika o ka ʻili o ke kalapona pili pili i ka neʻe ʻana o nā pūʻulu ikaika, a ʻo kēia mau pūʻulu ikaika ka nui o ka oxygen i loko o nā pūʻulu hana e like me ka pūʻulu māmā, ka hui spindle a me ka hui epoxy. ʻO ka helu o nā pūʻulu hana ma ka ʻili o ka fiber carbon e pili ana i ke ʻano o ka mālama electrochemical surface a me ke degere a i ʻole ka mahana o ka carbonization fiber. No ka laʻana, hāʻawi ka lapaʻau waika i nā hui hana like ʻole ma mua o ka mālama ʻana i ka alkali, a no nā kūlana lapaʻau like, ʻoi aku ka kiʻekiʻe o ka mahana carbonization, ʻoi aku ka liʻiliʻi o nā hui hana. ʻOi aku ka nui o nā pūʻulu hana haʻahaʻa haʻahaʻa haʻahaʻa ma muli o kona haʻahaʻa haʻahaʻa o ka carbonization, no laila e pane me ka hui epoxy i ka hoʻomākaukau ʻana i nā composites epoxy matrix, ʻoiai hiki ke nānā ʻole ʻia ka hopena o ka ʻōnaehana kalapona modulus kiʻekiʻe, a me ka fiber a me ka resin. ʻo ka hapa nui o ka launa pū ʻana nāwaliwali. Ua hōʻike ʻia nā haʻawina he nui e hiki ke hoʻomaikaʻi maikaʻi ʻia nā waiwai o nā mea hoʻohui ma o ka hoʻololi ʻana i ka microstructure interface o nā composites ma o ka hoʻololi ʻana i ka ʻili o ke kalapona kalapona, ʻo ia kekahi o nā wahi wela noiʻi ma ke kahua o nā mea hoʻopili kalapona.
