Ị nwere ike ichetụ n'echiche? “Ihe oghere” nke e jibu mee ihe na rọketi na ikuku turbine na-edegharị akụkọ ihe mere eme nke nkwado ụlọ - ọ bụcarbon eriri ntupu.

• Genetics Aerospace na 1960:

Ihe mmepụta nke carbon fiber filaments nke ụlọ ọrụ mmepụta ihe mere ka e webata ihe a, bụ́ nke dị ike okpukpu itoolu karịa ígwè ma dị ụzọ atọ n'ụzọ anọ dị mfe, ka e webatara ihe a kpọrọ mmadụ na nke mbụ ya.

• Oge mgbanwe na "agha na ígwè":

Ntupu na-eme ka ọ dị mma dị ka "codger ochie" nke ụwa ihe owuwu: ọ na-atụ oke elephant (ihe dị ka 25 n'arọ kwa square mita nke ntupu ume ike), ọ na-atụkwa egwu nnu, mmiri na oge - - ion ion chloride na-eme ka nchara ahụ gbasaa na mgbawa.
Nputa nkecarbon eriri ntupu ákwàna-agbaji mkpọchi ahụ kpamkpam: site na ịkwa akwa + epoxy resin impregnation, ọ na-eme ka ọkpụrụkpụ nke oyi akwa na-agba ume site na 5cm ruo 1.5cm, ịdị arọ bụ naanị 1/4 nke rebar, kamakwa na-eguzogide acid na alkali, mmiri mmiri, na na nkwado nke àkwà mmiri dị n'oké osimiri, ọ dịghị ihe ịrịba ama nke corrosion maka afọ 20.

Gịnị mere ndị injinia ji agba ọsọ iji ya? Uru hardcore ise kpughere

mesiri ike:a ghaghị iji ihe owuwu mee ihe iji kwekọọ na ngwa agha polymer! E jirila ngwa agha nkịtị mee ihe n'otu agbata obi n'ụzọ na-ezighi ezi, na-ebute mkwado oyi akwa nke drum wee daa - dị ka iji gluu na-arapara iko, gluu abụghị ihe kwesịrị ekwesị na mkpofu ọrụ.

• “Badeji a na-adịghị ahụ anya” maka ihe nketa ọdịnala na ụlọ ochie:

Beyer Bau, ụlọ narị afọ nke dị na Technische Universität Dresden dị na Germany, chọrọ nkwado ngwa ngwa n'ihi oke ibu, mana ọ dabere na mmachi nke nchekwa ihe ncheta nyere. Engineers na 6mm oké carbon eriri ntupu ákwà + mkpa oyi akwa nke ngwa agha, na ala nke doo "mado" a oyi akwa nke "transparent band-enyemaka", ọ bụghị nanị na ibu-ebu ikike welie 50%, ma ọ dịghị agbanwe ụlọ na nwetụrụ mbụ ọdịdị, na ọbụna Heritage Board ọkachamara toro: "Dị ka ụlọ ochie na-enweghị atụ ime a.

• Injinia okporo ụzọ "super patch":

Florida, United States, ogidi akwa mmiri gafere, nke ejiri akwa carbon fiber mesh mesie ike na 2003, ike sitere na "ndị na-adịghị ike" gbagoro 420%, ma ugbu a afọ 20 ka e mesịrị, ajọ ifufe ka kwụsiri ike dị ka ugwu dị n'ụsọ oké osimiri.

• “Mgbaaka ahụike” maka ụlọ:

na-etinye ihe mmetụta fiber optic n'imecarbon eriri ntupu, dị ka a "smart nche" maka ụlọ: a ịrịba ama ụlọ na Shanghai na-eji ya nyochaa mmezi na cracks na ozugbo, na data na-ebute site ná ozugbo na njikwa azụ ụlọ ọrụ, nke bụ 100 ugboro nke ọma karịa omenala ntuziaka nnyocha.
