Kodi mungaganizire? "Zam'mlengalenga" zomwe kale zinkagwiritsidwa ntchito popanga rocket casings ndi ma turbine turbine blade tsopano zikulembanso mbiri yolimbikitsa zomanga - ndicarbon fiber mesh.

• Zamlengalenga mu 1960s:

Kupanga mafakitale a carbon fiber filaments kunalola kuti zinthuzi, zomwe ndi zolimba kuwirikiza kasanu ndi kamodzi kuposa chitsulo koma kotala kotala kopepuka, kuti zidziwike kwa anthu kwa nthawi yoyamba. Poyambirira idasungidwa "magawo osankhika" monga zida zam'mlengalenga ndi zida zamasewera apamwamba, zidalukidwa pogwiritsa ntchito njira zachikhalidwe za nsalu, koma zinali ndi kuthekera kotembenuza dziko lapansi.

• Kusintha kwa "nkhondo pazitsulo":

Ma mesh ochiritsira wamba ali ngati "codger yakale" ya zomangamanga: imalemera ngati njovu (pafupifupi 25 kg pa sikweya mita imodzi ya mauna), komanso imawopa mchere, madzi, ndi nthawi - - Kukokoloka kwa ayoni wa kloridi kumapangitsa kuti chitsulo chiwonjezeke komanso kusweka.
Kuwonekera kwacarbon fiber mesh nsalukuphwanya kwathunthu kutsekereza: kudzera munjira yoluka + epoxy resin impregnation, imapangitsa makulidwe a wosanjikiza kuchokera 5cm mpaka 1.5cm, kulemera kwake ndi 1/4 yokha ya rebar, komanso kugonjetsedwa ndi asidi ndi zamchere, madzi a m'nyanja, komanso pakulimbitsa mlatho panyanja, palibe chizindikiro cha zaka 20.

Chifukwa chiyani mainjiniya akuthamangira kuzigwiritsa ntchito? Zopindulitsa zisanu zolimba zidawululidwa

kutsindika:zomangamanga ziyenera kugwiritsidwa ntchito kuti zifanane ndi matope a polima! Malo oyandikana nawo akhala akugwiritsidwa ntchito molakwika matope wamba, zomwe zimapangitsa kuti ng'oma zowonjezeretsa zigwe - monga kugwiritsa ntchito guluu kumata galasi, guluu siloyenera kufanana ndi kuwononga ntchito.

Kuchokera ku Mzinda Woletsedwa kupita ku Mlatho wa Cross-Sea: Ikusintha Dziko Lapansi mwakachetechete

• "Invisible Bandage" ya Cultural Heritage ndi Nyumba Zakale:

Beyer Bau, nyumba yazaka zana ku Technische Universität Dresden ku Germany, inali yofunikira kulimbikitsidwa chifukwa chakuchulukirachulukira kwa katundu, koma inali kutsatiridwa ndi zoletsa zotetezedwa ndi zipilala. Akatswiri ndi 6mm wandiweyani mpweya CHIKWANGWANI mauna nsalu + woonda wosanjikiza matope, pansi pa mtengo "phala" wosanjikiza "maonekera bandeji-thandizo", osati kuti katundu wonyamula mphamvu kumapangitsanso 50%, komanso sanasinthe nyumbayo mu maonekedwe pang'ono choyambirira, ndipo ngakhale akatswiri a Heritage Board adayamika nyumba yopanda kanthu : ".

• Kupanga magalimoto "super patch":

Florida, United States, mizati ya mlatho wodutsa panyanja, yolimbikitsidwa ndi nsalu ya carbon fiber mesh mu 2003, mphamvu yochokera ku "ofooka" inakwera 420%, ndipo tsopano zaka 20 pambuyo pake, mphepo yamkuntho idakali yokhazikika ngati phiri pamphepete mwa nyanja. Ntchito yapakhomo pachilumba cha Hong Kong-Zhuhai-Macao Bridge, idagwiritsanso ntchito mwakachetechete kupititsa patsogolo kamangidwe, motsutsana ndi kukokoloka kwa madzi a m'nyanja.

• "Chida chamatsenga chobwezeretsa zaka" chaching'ono chakale komanso chonyowa:

M'dera la 80's ku Beijing, ma slabs pansi adasweka kwambiri, ndipo cholinga choyambirira chinali kugwetsa ndikumanganso. Pambuyo pake ndi nsalu ya carbon fiber mesh + matope a polima, mtengo pa mita imodzi ndi 200 yuan, kuposa kumanganso 80% ya mtengo wopulumutsira, ndipo tsopano okhalamo akuti: "Imvani nyumbayo ili wamng'ono zaka 30!
Tsogolo lili pano: Kudzichiritsa nokha, kuyang'anira "zanzeru" zili m'njira

• "Dokotala wodzichiritsa" mu konkire:

Asayansi akupanga ma mesh a carbon fiber omwe "amadzichiritsa okha" - ma microcracks akachitika mwadongosolo, mauna amatha kugwiritsidwa ntchito ngati kulimbikitsa. - Pamene microcracks kuonekera mu dongosolo, makapisozi mu zinthu anaphulika kumasula wothandizila kukonza kuti basi kudzaza ming'alu. Mayeso ku labu ku UK awonetsa kuti zinthuzo zitha kukulitsa moyo wa konkriti mpaka zaka 200.

• "Chibangili chaumoyo" chanyumba:

imalowetsa ma sensor a fiber-optic mucarbon fiber mesh, monga "wotchi yanzeru" yomanga nyumba: nyumba yodziwika bwino ku Shanghai imagwiritsa ntchito kuyang'anira kukhazikika ndi ming'alu mu nthawi yeniyeni, ndipo deta imatumizidwa mwachindunji ku ofesi yoyang'anira kumbuyo, yomwe imakhala yogwira ntchito ka 100 kuposa momwe amayendera pamanja. Ndi 100 nthawi imayenera kuposa kuwunika kwachikhalidwe pamanja.
Malangizo achangu kwa mainjiniya ndi eni ake
1. Zida sankhani yoyenera, zotsatira zake kawiri ndi theka la khama:zindikirani zinthuzo ndi mphamvu zolimba ≥ 3400MPa ndi modulus of elasticity ≥ 230GPa, ndipo mutha kufunsa opanga kuti apereke malipoti oyesa.
2. Musakhale aulesi pomanga:Pansi pake payenera kupukutidwa bwino, ndipo matope a polima ayenera kusakanizidwa molingana ndi kuchuluka kwake.
3. Kukonzanso kwa nyumba zakale kofunika kwambiri:poyerekeza ndi kugwetsa ndi kumanganso, carbon fiber mesh reinforcement ikhoza kusunga mawonekedwe oyambirira a nyumbayo, komanso kusunga ndalama zoposa 60%.
Mapeto
Pamene zipangizo zakuthambo "pansi" kumalo omangamanga, tinapeza mwadzidzidzi: kulimbitsa koyambirira sikungasowe kuchita khama lalikulu, nyumba yakale yoyambirira ingakhalenso "kukula kumbuyo".Carbon fiber mesh nsaluali ngati "wopambana" muzomangamanga, ali ndi makhalidwe opepuka, amphamvu komanso okhalitsa, kotero kuti nyumba iliyonse yakale imakhala ndi mwayi wokonzanso moyo wake - ndipo izi zikhoza kukhala chiyambi cha kusintha kwa zinthu.
