ʻO ke kalapona kalapona (CF) he ʻano mea hou o ka fiber me ka ikaika kiʻekiʻe a me ka modulus kiʻekiʻe o ka ʻike kalapona ma luna o 95%.

ʻO ka helu T o ka carbon fiber e pili ana i ke kiʻekiʻe o nā mea kalapona, ʻo ka nate ʻoihana e pili ana i kahi ʻano mea kalapona i hana ʻia e Toray Company ma Iapana, a ma waho o ka ʻoihana e pili ana i nā mea kalapona kiʻekiʻe kiʻekiʻe.Hōʻike ʻo T i ka helu o nā tona o ka ikaika tensile i hiki i kahi ʻāpana kalapona me kahi ʻāpana keʻa o 1 kenimika kūhāhā ke kūpaʻa.No laila, ma ka laulā, ʻoi aku ka kiʻekiʻe o ka helu T, ʻoi aku ka kiʻekiʻe o ka pae o ke kalapona kalapona, ʻoi aku ka maikaʻi.

Ma nā ʻōlelo o ka haku mele, ua hōʻoia ʻia e nā hoʻokolohua ʻepekema ʻo ka hui kemika o T300 a me T700 ka nui o ke kalapona, me ka hapa nui o ka mua he 92.5% a ʻo ka hope 95.58%.ʻO ka lua he nitrogen, ʻo ka mua he 6.96%, ʻo ka hope he 4.24%. ʻO ka hoʻohālikelike, ʻoi aku ka kiʻekiʻe o ka maʻi kalapona o T700 ma mua o ka T300, a ʻoi aku ka kiʻekiʻe o ka mahana carbonization ma mua o ka T300, ʻoi aku ka nui o ke kalapona a me ka haʻahaʻa haʻahaʻa.

ʻO T300 a me T700 e pili ana i nā māka o ka fiber kalapona, i ana maʻamau e ka ikaika tensile.Pono ka ikaika tensile o T300 i 3.5Gpa;Pono ka tensile T700 e loaʻa i ka 4.9Gpa.I kēia manawa, hiki i ka 12k carbon fiber ke hiki i ka pae T700.
