Kodi pali ulusi wachilengedwe womwe uli wamphamvu kuposa carbon fiber?

Zimatengera zomwe mukutanthauza ndi mphamvu. nthawi zambiri ayi, komabe ali ndi mawonekedwe osangalatsa komanso mwayi wopitilira mpweya wa kaboni pamagwiritsidwe angapo. Fulakisi (nsalu) imapereka ntchito yofanana ndi ulusi wowoneka bwino (wotsika mtengo kwambiri komanso wocheperako), fulakesi imakhala pafupifupi 2/3rds yolimba kwambiri ngati kaboni fiber. Flax imaposa kusinthasintha kwa kaboni. Zindikirani mawu oti 'mozungulira' chifukwa ndi zinthu zachilengedwe, chifukwa chake, amatha kusiyanasiyana kuchokera kumtundu umodzi kapena kutsata, izi zimalepheretsa kugwiritsa ntchito luso lake monga mainjiniya akufuna kudziwa momwe amagwirira ntchito, komabe, pazovuta zochepa, ndizinthu zodabwitsa zokhala ndi zokongoletsa zabwino (zojambula zamtundu umodzi zimamveka ngati nkhuni zolimba, kutentha, komanso kugwiritsa ntchito nyimbo zabwino, zokometsera zokometsera, zokometsera, zokometsera zokometsera, zokometsera zokometsera, zokometsera zokometsera). ngakhale matumba).

Kwa munthu amene ali ndi chidwi chophunzira ma composite nditha kuyamba ndi nsalu yansalu yomveka bwino kuti adziwe zoyambira, zingateteze chuma chochepa, mukakhala omasuka ndi chitsanzo cha nsalu ndiye gwiritsani ntchito ulusi wa carbon. Silika ali ndi zinthu zina zochititsa chidwi, mwachitsanzo, samva zonyezimira (zanzeru kwambiri pakugwiritsa ntchito ngati mabwato). Chofanana chake chapafupi ndi Kevlar, komabe, sichikhala cholimba kwambiri poyerekeza ndi kaboni fiber. Laboratory yasayansi idayesa kudyetsa mbozi za carbon nanoparticles (sindikuganiza kuti zimawavulaza, komabe zimawongolera modulus).

Ma Nanotubes amatha kulumikizana kwambiri pa silika chifukwa amatulutsidwa ndikukokedwa. Mpweya wa carbon nanotubes umapereka kuthekera kwa kusintha kuposa mpweya wa kaboni ndipo ukhoza kuwonjezeredwa kuzinthu zamagulu ophatikizirapo, komabe, zonsezi sizikhala katundu wachilengedwe. Ubwino wa zinthu zachilengedwe nthawi zambiri zimakhala zotsika mtengo, zimawonongeka pang'onopang'ono komanso zimapatsa mphamvu zowonongeka komanso zimamatira bwino ndi organic compound system (yomwe imatha kukhala bio-resin) komanso kusinthika. Ulusi wachilengedwe umakhala wosinthasintha, wanzeru pazinthu monga chingwe ndi (matanga) nsalu. Flax nthawi zambiri imamera m'malo ambiri (mosiyana ndi thonje lalifupi lokhazikika), maiko ambiri adapanga kale chifukwa ali ndi ulusi wautali wautali, anali odziwika bwino kuti amapota kuyambira zaka zosachepera 3,000 BCE ndipo amalimidwa kuyambira nthawi yamkuwa.
