Ngomhlaka-19 Meyi, iToray yaseJapan yamemezela ukuthuthukiswa kobuchwepheshe bokudlulisa ukushisa obusebenza kahle, okuthuthukisa ukuhanjiswa kokushisa kwezinhlanganisela ze-carbon fiber ezingeni elifanayo nezinto zensimbi. Lobu buchwepheshe budlulisela ngempumelelo ukushisa okukhiqizwe ngaphakathi kwezinto ngaphandle ngendlela yangaphakathi, okusiza ekunciphiseni ukuguga kwebhethri emkhakheni wezokuthutha ezihambayo.

I-carbon fiber, eyaziwa ngesisindo sayo esincane kanye namandla ayo aphezulu, manje isetshenziselwa ukwenza izindiza, izimoto, izingxenye zokwakha, imishini yezemidlalo kanye nemishini kagesi. Uma kuqhathaniswa nezinto ze-alloy, ukuhanjiswa kokushisa bekulokhu kuyiphutha, okuye kwaba yindlela ososayensi abebezama ukuyithuthukisa iminyaka eminingi. Ikakhulukazi ekuthuthukisweni okukhulayo kwezimoto ezintsha zamandla ezikhuthaza ukuxhumana, ukwabelana, ukuzenzekela kanye nokufakwa kukagesi, izinto ezihlanganisiwe ze-carbon fiber ziye zaba amandla abalulekile okonga amandla kanye nokunciphisa isisindo sezingxenye ezihlobene, ikakhulukazi izingxenye zebhethri. Ngakho-ke, sekuyinto ephuthumayo kakhulu yokulungisa amaphutha ayo nokuthuthukisa ngempumelelo ukuhanjiswa kokushisa kwe-CFRP.

Ngaphambilini, ososayensi babezame ukuhambisa ukushisa ngokufaka izendlalelo ze-graphite. Kodwa-ke, ungqimba lwe-graphite kulula ukuluqhekeza, ukuluphula nokululimaza, okuzonciphisa ukusebenza kwezinhlanganisela ze-carbon fiber.

Ukuze kuxazululwe le nkinga, iToray yakha inethiwekhi enezinhlangothi ezintathu ye-CFRP enezimbobo enobunzima obuphezulu kanye ne-fibre yekhabhoni emfushane. Ukuze kucaciswe, i-CFRP enezimbobo isetshenziselwa ukusekela nokuvikela ungqimba lwe-graphite ukwakha isakhiwo sokuqhuba ukushisa, bese kubekwa i-CFRP prepreg phezu kobuso bayo, ukuze kube nzima ukufeza ukuqhubela ukushisa kwe-CFRP evamile, ngisho nangaphezulu kunezinye izinto zensimbi, ngaphandle kokuthinta izakhiwo zemishini.

Ngenxa yobukhulu kanye nendawo yesendlalelo se-graphite, okungukuthi, indlela yokuqhuba ukushisa, i-Toray ithole inkululeko ephelele yokuklama, ukuze ifinyelele ukuphathwa kahle kokushisa kwezingxenye.

Ngalobu buchwepheshe obukhethekile, iToray igcina izinzuzo ze-CFRP ngokwesisindo esincane kanye namandla aphezulu, ngenkathi idlulisa ukushisa ngempumelelo kusuka ebhethrini kanye nasezifundeni zikagesi. Ubuchwepheshe kulindeleke ukuthi busetshenziswe ezindaweni ezifana nokuthuthwa kweselula, izinto zikagesi eziphathwayo kanye namadivayisi agqokwayo.
