Alendo a 32,000 ndi owonetsa 1201 ochokera kumayiko a 100 amakumana maso ndi maso ku Paris kuti awonetse magulu apadziko lonse lapansi.

Magulu akulongedza magwiridwe antchito kwambiri kukhala ma voliyumu ang'onoang'ono komanso osasunthika ndiwomwe adachokera ku chiwonetsero chazamalonda chamagulu a JEC World chomwe chidachitikira ku Paris pa Meyi 3-5, kukopa alendo opitilira 32,000 ndi owonetsa 1201 ochokera kumayiko oposa 100 kupangitsa kuti ikhale yapadziko lonse lapansi.

Kuchokera pamawonekedwe a ulusi ndi nsalu panali zambiri zoti muwone kuchokera ku ulusi wobwezerezedwanso wa kaboni ndi zophatikizika zapa cellulose mpaka kupindika kwa ulusi ndi kusindikiza kwa 3D kosakanizidwa kwa ulusi. Zamlengalenga ndi zamagalimoto zimakhalabe misika yayikulu, koma ndi zodabwitsa zina zomwe zimayendetsedwa ndi chilengedwe chonse, pomwe zosayembekezereka ndizochitika zina zamagulu a nsapato.

Kukula kwa fiber ndi nsalu za kompositi

Ulusi wa kaboni ndi magalasi umakhalabe wofunikira kwambiri pazophatikizira, komabe kusunthira kukufika pamlingo wapamwamba wokhazikika kwawona kupangidwa kwa ulusi wopangidwanso ndi mpweya (rCarbon Fiber) komanso kugwiritsa ntchito hemp, basalt ndi zida za biobased.

Mabungwe a Germany Institutes of Textile and Fiber Research (DITF) amayang'ana kwambiri kukhazikika kuchokera ku rCarbon Fiber kupita ku biomimicry zoluka ndi kugwiritsa ntchito biomatadium. PurCell ndi 100% zinthu za cellulose zomwe zimatha kubwezeredwanso komanso kompositi. Ulusi wa cellulose umasungunuka mu madzi a ayoni omwe alibe poizoni ndipo amatha kutsukidwa ndikuwumitsa zinthuzo kumapeto kwa njirayi. Kubwezeretsanso ndondomekoyi kusinthidwa, choyamba ndikudula PurCell mu tiziduswa tating'onoting'ono musanasungunuke mumadzi a ionic. Ndi compostable kwathunthu ndipo palibe zinyalala mapeto a moyo. Zida zophatikizika zooneka ngati Z zapangidwa popanda ukadaulo wapadera wofunikira. Ukadaulo umagwirizana ndi ntchito zingapo monga zida zamkati zamagalimoto.

Kukula kwakukulu kumakhala kokhazikika

Kukopa kwambiri kwa alendo otopa ndi maulendo a Solvay ndi Vertical Aerospace Partnership adapereka chithunzithunzi chaupainiya chamagetsi oyendetsa ndege omwe angalole kuyenda mothamanga kwambiri pamtunda waufupi. EVTOL imayang'anira kuyenda kwamlengalenga kumatauni komwe kumathamanga mpaka 200mph, kutulutsa ziro komanso kuyenda mwabata kwambiri poyerekeza ndi helikopita yoyenda mpaka anthu anayi.

Thermoset ndi thermoplastic composites ali mu airframe yaikulu komanso ma rotor blade, ma motors amagetsi, zigawo za batri ndi zotsekera. Izi zakonzedwa kuti zikwaniritse kuuma kolimba, kulekerera kuwonongeka ndi magwiridwe antchito osamveka bwino kuti zithandizire mkhalidwe wovuta wa ndegeyo ndi maulendo ake omwe amayembekezeka kunyamuka ndi kutera pafupipafupi.

Phindu lalikulu la Composite pakukhazikika ndi chimodzi mwazinthu zabwino zolimbitsa thupi potengera kulemera kwa zinthu zolemera.

A&P Technology ili patsogolo paukadaulo woluka wa Megabraiders kutengera ukadaulo ku sikelo ina - kwenikweni. Zomwe zidachitikazi zidayamba mu 1986 pomwe General Electric Aircraft Engines (GEAE) adalamula lamba wosungira injini ya jet kuposa momwe makina omwe analipo kale, motero kampaniyo idapanga ndikumanga makina oluka onyamula 400. Izi zidatsatiridwa ndi makina oluka onyamula 600 omwe amafunikira sleeving ya biaxial kuti athandizire mbali yaku airbag yamagalimoto. Kapangidwe kazinthu kachikwama ka airbag kadapangitsa kuti pakhale zoluka zoposa 48 miliyoni za airbag zomwe zimagwiritsidwa ntchito ndi BMW, Land Rover, MINI Cooper ndi Cadillac Escalade.

Composites mu nsapato

Nsapato mwina ndizoyimilira zochepa zomwe sizikuyembekezeka pamsika ku JEC, ndipo panali zochitika zingapo zomwe ziyenera kuwonedwa. Orbital Composites adapereka masomphenya a 3D yosindikiza kaboni fiber pa nsapato kuti musinthe mwamakonda ndikuchita masewera mwachitsanzo. Nsapatoyo imasinthidwa mwachiloboti pomwe ulusi umasindikizidwa pamenepo. Toray adawonetsa kuthekera kwawo pazophatikizira pogwiritsa ntchito ukadaulo wa Toray CFRT TW-1000 wophatikizira mapazi. Kuluka kwa twill kumagwiritsa ntchito Polymethyl methacrylate (PMMA), ulusi wa kaboni ndi magalasi monga maziko a mbale yowonda kwambiri, yopepuka, yokhazikika yopangidwira kuyenda kosiyanasiyana komanso kubwereranso kwamphamvu.

Toray CFRT SS-S000 (SuperSkin) imagwiritsa ntchito Thermoplastic polyurethane (TPU) ndi kaboni fiber ndipo imagwiritsidwa ntchito mu kauntala ya chidendene kuti ikhale yopyapyala, yopepuka komanso yabwino. Zotukuka monga izi zimatsegulira njira ya nsapato yowoneka bwino kwambiri yosinthira kukula kwa phazi ndi mawonekedwe ake komanso momwe amagwirira ntchito. Tsogolo la nsapato ndi zophatikizika sizingakhale zofanana.
