Ngo-2021, ubhubhane olusha lusenzima, futhi ukukhula komnotho womhlaba kulinganiselwe kakhulu.Nokho, igciwane elisha lomqhele alikwazi ukumisa ijubane lenqubekelaphambili yesayensi nezobuchwepheshe.Izinto zempi ziwubuchwepheshe obuyisisekelo nobusezingeni eliphezulu.Ngaphansi kwethonya lezidingo zokuthuthukiswa zokushintshwa kwemishini, impumelelo eyingqophamlando yobuchwepheshe isamangalisa.Eminyakeni emithathu edlule, sethule ngokulandelana "Amathrendi Okuthuthuka Okukhulu Obuchwepheshe Bezinto Zezempi Zangaphandle".Ngokuhlela ngokuhlelekile inqubekelaphambili yezobuchwepheshe emkhakheni wezinto zempi kulo nyaka, sikhethe ubuchwepheshe obuyishumi obunethonya elikhulu, futhi sahlulela inkambiso yentuthuko yesikhathi esizayo yensimu yezinto zokwakha, abafundi nabafundisi abakhuthazayo.Abacwaningi besayensi, abahlinzeka ngenkundla yezingxoxo.Eminyakeni emithathu edlule, lo msebenzi uye wazuza izimpendulo ezinhle.
Ngo-2021, umfutho wokuthuthukiswa kwezinto ezihlanganisiwe uzoba namandla, futhi bazokwenza kahle ekuhloleni isicelo emikhakheni ye-aerospace nezikhali;ezindaweni ezihlukene zohlelo lokusebenza, izinto ezintsha ezinjengokumelana nokusebenza kwemisebe ephezulu kanye nokumelana nokugqoka kuzovela;I-2nm process chips izokhanyisa izinto zikagesi.Esiqongweni sokuthuthukiswa kwezinto ezisebenzayo zolwazi, izinto ze-bismuth zivule indlela ye-chips ye-1nm yenqubo.Ngaphezu kwalokho, ukwethulwa kwama-algorithms amasha kuphinde kwasheshisa ukutholakala kwezinhlanganisela ezihlukahlukene ze-inorganic kanye nezinto ezisezingeni eliphakeme ze-entropy alloy ezithembele ekwakhiweni kwengxenye.
NgoJanuwari 19, 2022, Isikhungo Sokucwaninga Sokuthuthukiswa Kwemboni Yezindiza YaseChina sahlela ochwepheshe eBeijing ukuthi benze umsebenzi wokukhetha "Amathrendi Amakhulu Kwezinto Zezempi Zangaphandle ngo-2021".Kusukela enanini lamathrendi entuthuko ayi-158 emikhakheni emihlanu, okuhlanganisa izinto zensimbi ezisebenzayo, izinto ezithuthukisiwe eziyinhlanganisela, izinto zokusebenza ezikhethekile, izinto ezisetshenziswayo zolwazi lwe-elekthronikhi, nezinto zokusetshenziswa ezibalulekile, lezi zindlela zobuchwepheshe eziyishumi ezilandelayo zikhethwa ukuze zisetshenziswe yizikhungo ezithatha izinqumo, amayunithi ocwaningo lwesayensi nabafundi.
I-US Air Force iqinisekise ngempumelelo i-continuous fibre 3D printer wing spars
Ukukhiqizwa okusheshayo kanye nokwenza ngokwezifiso okuguquguqukayo okungabizi kakhulu kuyizidingo ezibalulekile zokuthuthukiswa kwamanje kwezinto ezihlanganisiwe ze-carbon fiber.I-US Air Force Research Laboratory igxile kakhulu kubuchwepheshe bokuphrinta be-fiber 3D obuqhubekayo, ngethemba lokuthi ingaba indlela yobuchwepheshe ephumelelayo yokuthatha indawo yezindlela zokukhiqiza eziyinhlanganisela evamile, ukunciphisa izindleko kanye nesikhathi sokuhola sezingxenye eziyinhlanganisela.Ngo-April 2021, i-US Continuous Composites yasebenzisa ubuchwepheshe bayo bokuphrinta be-fiber 3D (CF3D) obunamalungelo obunikazi obunamalungelo obunikazi ukuze baphrinte ngempumelelo ama-spar ama-spar amamitha ayi-2.4 ubude, amakhilogremu angu-1.8 we-carbon fiber composite spar, beqeda I-US Air Force Research Laboratory.
Inkontileka yeminyaka emibili yeWing Structure Design for Manufacturing (WiSDM).Imiphumela yokuhlola eqinile yendawo yokugcina yomhlangano wephiko, iphiko elihlanganiswe ngokugcwele lalayishwa ku-160% womthwalo womkhawulo wokuklama.Akukho silinganiso noma umonakalo obonakalayo kuma-spars aphrintiwe we-CF3D otholiwe.I-carbon fiber spar ephrintiwe izuze ingxenyena yevolumu ye-fiber engu-60% cishe ne-1% -2% voids.
Le ndlela entsha yokwenziwa kwenhlanganisela ihlanganisa ukumiliselwa kwe-in-situ, ukuhlanganiswa nokwelapha, okunciphisa kakhulu izindleko nezikhathi zokuhola.Inqubo ezenzakalelayo ngokugcwele ihlanganisa ukusika nokufaka kabusha i-ply drop kanye nogqinsi lwengxenye eguquguqukayo ngaphakathi kwesakhiwo.Iphrojekthi, eyenza kahle imicu yesakhiwo eqondisiwe, iyindaba yempumelelo kusetshenziswa isixazululo sezinto ezibonakalayo se-CF3D, esinomthelela ekwakhiweni kwezingxenye ezibizayo zesakhiwo se-aerospace.
