Uthelekiso lweNdleko-uMsebenzi kunye neCarbon Fiber (CFRP)
Uthelekiso: I-Basalt Fiber (BFRP) vs. I-Carbon Fiber (CFRP)
| Ubukhulu | I-Basalt I-Fiber Reinforced Polymer (BFRP) | I-Carbon Fiber Reinforced Polymer (CFRP) |
| Ixabiso lezinto eziphathekayo | Iipleyiti: malunga ne-60–100 RMB/kg (Ezasekhaya) | Iipleyiti: malunga ne-150–300 RMB/kg (uHlelo lwe-T300) |
| Amandla athile | Phakathi (≈250) | Phezulu (≈600) |
| IModulus ethile | Iphantsi kakhulu (≈20) | Phezulu (≈60-100) |
| Ukumelana neempembelelo | Phakathi (Ubuthuntu obuphezulu kune-CFRP) | Iphezulu kakhulu (Ukuqina okuhle) |
| Iindleko zokucubungula | Iipleyiti ezixutyiweyo kulula ukuzicubungula, kodwa ukubumba okunzima kufuna iinkqubo ezongezelelweyo. | Ixabiso lokucinezela ngobushushu ngaphambi kokulungiselela liphezulu, kodwa livumela ukubumba okudibeneyo. |

| Ukunciphisa Ubunzima | Ukunciphisa ubunzima ngama-20–30% xa kuthelekiswa ne-aluminium alloy. | Ukunciphisa ubunzima ngama-40–50% xa kuthelekiswa ne-aluminium alloy. |
Uhlalutyo lweMeko yoBuchule bokusebenza kakuhle kweendleko
- Iidrone ezixabisa kancinci (umz., ukuhlolwa, iidrone zezolimo): – I-BFRP inokutshintsha ezinye izinto ze-aluminium alloy, ngexabiso eliphantsi ngama-30–50% kune-CFRP kunye nokumelana nokugqwala okuphezulu, okubonelela ngexabiso elifanelekileyo.
- Ii-aplikeshini ezifuna ukuqina okuphezulu kunye noyilo olukhaphukhaphu (umz., iidroni zomdyarho, iidroni zefoto zomoya): – I-CFRP inika inzuzo ebalulekileyo kwi-modulus yokuthamba, inciphisa ukuguquguquka kwe-aerodynamic; nangona ibiza kakhulu, ukusebenza kwayo akunakuthathelwa indawo.
- Izicelo ezineemfuno ezizodwa zokusebenza: Ukuba kufuneka ukukhanya kwe-electromagnetic okanye ukunciphisa ukudambisa/ukungcangcazela, i-BFRP ingasebenza njengesixhobo esongezelelweyo kwizinto ezithile (umz., ii-radar domes).
- Imingeni yoBugcisa kunye neMiyalelo yokuSebenzisa ngcono
- Uyilo lwesakhiwo se-hybrid: I-BFRP + i-CFRP laminates: Kufuywa i-carbon fiber kwiindawo ezineemfuno zokuqina okuphezulu ukuze kulinganiswe iindleko kunye nokusebenza.
- Uphuculo lwenkqubo: Phuhlisa ii-BFRP prepregs okanye izinto eziqiniswe ngefayibha eziprintiweyo nge-3D ukuphucula amandla okwenza izakhiwo ezintsonkothileyo.
- Itekhnoloji yokudibanisa: Sebenzisa iijoyinti ezidityanisiweyo ezinee-adhesive okanye i-ultrasonic welding ukuphucula ukusebenza kakuhle kwamalungu.
Ngokusekelwe kuhlalutyo olungasentla, i-BFRP ifanelekile kwizakhiwo ezinomthwalo ophakathi ukuya kophantsi kwii-UAV ezincinci kwaye inika ixabiso lokusetyenziswa ngokwemiqathango yokunciphisa ubunzima, ukumelana nokugqwala, kunye nokunciphisa ukuxinana/ukungcangcazela; nangona kunjalo, kufuneka ithintelwe kwiindawo ezifuna ukuqina okuphezulu. Ukuba ukuqina akuyonto ibalulekileyo kodwa ixabiso liyiyo, i-BFRP inikezela ngokusebenza ngcono kakhulu kweendleko kune-CFRP.
Ukongeza, uyilo lwe-BFRP/CFRP hybrid lungaqwalaselwa ukuze luphucule iindleko.
Uhlalutyo lwe-Finite element (FEA) lungasetyenziselwa ukulinganisa izinto ezithile (ezifana ne-airframe), ukuthelekisa ubunzima kunye neendleko ze-BFRP kunye ne-CFRP phantsi kwezinto ezifanayo zokhuseleko ukuqhuba ukukhethwa kwezinto ngokusekelwe kwidatha.
