I ka makahiki 2021, ua koʻikoʻi ka maʻi kalaunu hou, a ua kaupalena ʻia ka ulu ʻana o ka hoʻokele waiwai honua.Eia nō naʻe, ʻaʻole hiki i ka virus lei aliʻi hou ke hoʻōki i ka wikiwiki o ka holomua ʻepekema a me ka ʻenehana.ʻO nā mea kaua ka ʻenehana maʻamau a ʻokiʻoki.Ma lalo o ka traction o ka hoʻomohala ʻana i nā pono o ka hoʻololi ʻana i nā mea hana, ʻoi aku ka maikaʻi o ka holomua ʻenehana.I nā makahiki ʻekolu i hala iho nei, ua hoʻomaka mākou i ka "Major Development Trends of Foreign Military Materials Technology".Ma ka hoʻokaʻawale ʻana i ka holomua ʻenehana i ke kahua o nā mea kaua i kēia makahiki, ua koho mākou i nā ʻenehana he ʻumi me ka mana koʻikoʻi, a ua hoʻoholo i ke ʻano o ka hoʻomohala ʻana i ka wā e hiki mai ana o ke kahua waiwai, hoʻoulu i ka poʻe heluhelu a me nā mea heluhelu.ʻO nā mea noiʻi ʻepekema, hāʻawi i kahi kahua no ke kūkākūkā.I nā makahiki ʻekolu i hala iho nei, ua loaʻa i kēia hana nā pane maikaʻi.
I ka makahiki 2021, e ikaika ana ka manawa o ka hoʻomohala ʻana o nā mea hoʻohuihui, a e hana maikaʻi lākou i ka noiʻi noiʻi ma nā kahua o ka aerospace a me nā mea kaua;no nā kaiapuni hoʻohana like ʻole, e puka mai ana nā mea hou e like me ke kūpaʻa radiation kiʻekiʻe a me ke kūpaʻa ʻaʻahu;E hoʻomālamalama nā pahu hana 2nm i ka uila.Ma kahi kiʻekiʻe o ka hoʻomohala ʻana i nā mea hana ʻike, ua wehe nā mea bismuth i ke ala no ka 1nm process chips.Eia kekahi,ʻo ka hoʻokomoʻana i nā algorithms hou i hoʻonui i ka loaʻaʻana o nā mea likeʻole o nā mea hoʻohuihui a me nā mea hoʻohui kiʻekiʻe-entropy e hilinaʻi nei i ka hoʻolālā mea.
Ma Ianuali 19, 2022, China Aviation Industry Development Research Center i hoʻonohonoho i nā loea ma Beijing e hoʻokō i ka hana koho o "Major Trends in Foreign Military Materials in 2021".Mai ka huina o 158 mau ʻano hoʻomohala ma ʻelima mau kahua, me nā mea metala hana, nā mea hoʻohui holomua, nā mea hana kūikawā, nā mea hana ʻike uila, a me nā mea kī kī, ua koho ʻia nā ʻano ʻenehana nui he ʻumi no ke kuhikuhi ʻana e nā hui hoʻoholo. nā ʻāpana noiʻi ʻepekema a me nā mea heluhelu.
Ua hōʻoia maikaʻi ka US Air Force i nā ʻēheu paʻi paʻi fiber 3D mau
ʻO ka hana wikiwiki a me ka hana maʻalahi haʻahaʻa haʻahaʻa nā koi koʻikoʻi no ka hoʻomohala ʻana i kēia manawa o nā mea hana carbon fiber composite.Ke nānā nui nei ka US Air Force Research Laboratory i ka ʻenehana paʻi fiber 3D mau, me ka manaʻo e hiki ke lilo i ʻenehana holomua e hoʻololi i nā ʻano hana hana kuʻuna, e hōʻemi ana i ke kumukūʻai a me ka manawa alakaʻi o nā ʻāpana composite.I ʻApelila 2021, ua hoʻohana ʻo US Continuous Composites i kāna ʻenehana paʻi paʻi 3D patented continuous fiber (CF3D) e paʻi kūleʻa i ʻelua mau hui spar 2.4-mika-lōʻihi, 1.8-kilogram carbon fiber composite spar, e hoʻopau ana i ka US Air Force Research Laboratory.
ʻElua makahiki Wing Structure Design for Manufacturing (WiSDM) aelike.Nā hopena ho'āʻo static o ka ʻili hui ʻēheu hope loa, ua hoʻouka ʻia ka ʻēheu i hui piha ʻia i 160% o ka ukana palena hoʻolālā.ʻAʻole i ʻike ʻia ke ana a i ʻole ka pōʻino ʻike i nā spars paʻi CF3D.Ua loaʻa i ka spar carbon fiber i paʻi ʻia ka hapa nui o ka fiber o 60% me ka 1% -2% voids.
Hōʻike kēia ʻano hana hoʻohui hou i ka impregnation in-situ, consolidation a me ka hoʻōla ʻana, e hōʻemi nui ana i nā kumukūʻai a me nā manawa alakaʻi.ʻO ke kaʻina hana ʻakomi piha e hōʻike ana i ka ʻoki ʻana a me ka hoʻihoʻi hou ʻana no ka hāʻule ʻana o ka ply a me ka mānoanoa ʻāpana ʻokoʻa i loko o ka hale.He moʻolelo kūleʻa ka pāhana e hoʻohana ana i kahi hoʻonā waiwai CF3D maʻamau, me nā hopena no ka hana ʻana i nā ʻāpana aerospace pipiʻi.
