Vhiki rino chete, vaongorori paDartmouth College vakagadzira 3D inodhinda smart inki inogona kushandura chimiro uye ruvara. Izvo zvakasiyana nezvimwe zvikwata zvinoshandisa tekinoroji yekudhinda ye4D kuita zvinhu zvitsva. Suong Van Hoa, purofesa muDhipatimendi reMechanical, Industrial and Aerospace Engineering yeConcordia University, ari kushandisa 4D kudhinda tekinoroji kugadzira zvinhu zvakaumbwa zvinogona kukotama zvega pasina kushandisa mold.

"Kudhinda kwe4D kunotibvumira kugadzira zvimiro zvakakomberedzwa pasina chikonzero chekugadzira mold dzakakombama," akadaro Hoa. "Chandinonyanya kuwana ndechekuti vanhu vanogona kugadzira zvinhu zvakakomberedzwa zvakakomberedzwa-refu inoenderera fiber ine yakakwirira michina zvinhu, izvo zvinogona kukurumidza uye zvakanyanya hupfumi."

Kazhinji, matanho akati wandei anodiwa mukugadzira zvinhu zvakaita sezvitubu zvemashizha zvakaumbwa, zvinova zvinoremesa zvekuvhundutsa mumotokari. Kuti ugadzire zvikamu zvakaita S, molds dzakaita S dzinoda kugadzirwa nezvinhu zvakasimba sesimbi. Iyo yakasimbiswa jira pre-yakamirirwa neiyo resin system inozoiswa pane mold kuita chikamu chakaumbwa. Nekudaro, Hoa akataura kuti kushandiswa kwe4D kudhinda tekinoroji kunogona kusiya matanho ekutanga ekuvaka mold dzakaoma.

"Kudhindwa kwe4D kwezvinhu zvakasanganiswa kunotora mukana wekuderera kweiyo matrix resin uye mutsauko mukupisa kwemafuta eshrinkage coefficients ane akasiyana fiber orientation, nekudaro achimutsa shanduko yechimiro panguva yekurapa uye kutonhora," akadaro. "Unhu uhwu hunogona kushandiswa kugadzira zvidimbu zvine curved geometries pasina kudikanwa kwekuumbwa kwakaoma. Naizvozvo, kugadzirwa kweakakomberedzwa maumbirwo anogona kukurumidza uye nehupfumi. Zvisinei, dhigirii rekuchinja kwechimiro zvinoenderana nehunhu hwezvinhu, kutaridzika kwefiber, uye stacking. Layer sequence uye kugadzira maitiro."

Chikamu chekutsvagisa kwaHoa chinosanganisira kuongororazve anisotropic zvimiro zveiyo composite layer. Anisotropy maitiro anoita chinhu kana chaiswa mitoro pamwe nematemo akasiyana. Iyo anisotropic pfuma yechinhu chiyero chekuti inoshanduka sei maererano nezvimwe zvinhu. Semuyenzaniso, resin shrinkage inogona kukonzera deformation yezvinhu, kana shanduko yetembiricha inogona kukonzera kuwedzera fiber kana kudonha. Sekureva kwaHoa, kunzwisisa uye kutonga kwekuchinja uku ndiko kiyi yekugadzira laminates akakomberedzwa ekupeta mold.

Akati: "Anisotropy yakagara ichionekwa semutoro munguva yakapfuura. Iye zvino ndavaona sechinhu chinokosha."

Hoa anotenda kuti tekinoroji inogona kushandiswa kune aerospace uye mamwe minda.

"Chimwe chishandiso zvimiro zvemuchadenga senge satellite, izvo zvinokanganiswa nekushanduka kwekushisa kwakanyanya," akadaro. "Chimiro chinogona kuvhurwa masikati (kana tembiricha yakakwira) kuunganidza simba rezuva uye kuvharwa usiku kuchengetedza mukati maro."

Gore rapfuura, Hoa akave wekutanga wekuCanada kugadzwa senhengo yeAmerican Composites Association. Akaburitsa tsvakiridzo yake mubepa rakanzi "mipiro yakatanhamara kunharaunda yemubatanidzwa kuburikidza nekutsvaga, kuita, dzidzo uye sevhisi".
