Kungenzeka Ukusebenzisa I-Basalt Fiber Ezindaweni Ezincane Ze-UAV
Ukubuka Konke Kwezakhiwo ze- I-Basalt Fiber Eqinisiwe I-Polymer (i-bfrp)
Uma sithatha ishidi elinobukhulu obungu-5 mm elinobukhulu obungu-5 mm njengesibonelo, imingcele yalo evamile yomzimba yilena elandelayo: - Amandla okunamathela: ≥500 MPa
- I-Modulus yokunwebeka: ≥40 GPa
- Ubuningi: 1.8–2.0 g/cm³
- Ukwelulwa ngesikhathi sokuphumula: 2.5–3.0%
- Ukumelana Nokugqwala: Kuhle kakhulu (kumelana nama-acid, ama-alkali, kanye nemisebe ye-UV)
- Isilinganiso sokunwetshwa kokushisa: Kufana nokhonkolo; ukusebenza kahle kokushisa okuphansi
Ukuhlaziywa Kokwenzeka Kokusetshenziswa Kwezakhiwo Ezincane Ze-UAV
- Izinzuzo
- Amandla okunciphisa isisindo: Njengoba ubuningi buphansi kunobe-aluminium alloy (2.7 g/cm³), kwenza kube lula ukunciphisa isisindo, ngaleyo ndlela kuthuthukiswe ukukhuthazela kokundiza kanye nokunyakaza.
- Amandla athile kanye ne-modulus ethile: Amandla athile (amandla/ubuningi): ≈250–280 MPa·cm³/g, angcono kune-aluminium alloy (≈140) kodwa aphansi kune-carbon fiber (≈600).
- I-modulus ethile (i-modulus/ubuningi): ≈20–22 GPa·cm³/g, eqhathaniswa ne-aluminium alloy kodwa ingxenye eyodwa kwezintathu kuphela ye-carbon fiber.
- Izici zokudambisa ukudlidliza: I-coefficient ephezulu yokudambisa kune-carbon fiber, kunciphisa ukudlidliza kokundiza nokuthuthukisa ukuzinza kwenzwa. • Ukucaca kwe-electromagnetic: Akuphazamisi izimpawu zokuxhumana, okwenza kufaneleke ezindaweni ze-radar noma ze-antenna.
- Ukumelana nemvelo: Kumelana nokushisa okumanzi nokugqwala, kufanelekile kuma-UAV ezindaweni zasolwandle noma zezimboni.
- Izinhlelo Zokusebenza Ezinconyiwe
- Izakhiwo zomthwalo ophakathi kuya phansi: Ozimele be-fuselage, izisekelo zegiya lokufika, izimbambo zamaphiko.
- Izingxenye ezingathwali umthwalo: Izikhonkwane ze-antenna, amathreyi ebhethri, izindawo zokufaka izinzwa.
- Izingxenye zezindawo ezikhethekile: Izingxenye ezivezwe ezixazululweni zezibulala-zinambuzane kuma-UAV ezolimo, imizimba yama-UAV asemanzini.
Ukuqhathaniswa Kwezindleko Nokusebenza Ne-Carbon Fiber (CFRP)
Ukuqhathanisa: I-Basalt Fiber (BFRP) vs. I-Carbon Fiber (CFRP)
| Ubukhulu | I-Basalt I-Fiber Reinforced Polymer (BFRP) | I-Carbon Fiber Reinforced Polymer (CFRP) |
| Izindleko Zezinto Ezibalulekile | Amapuleti: cishe 60–100 RMB/kg (Ekhaya) | Amapuleti: cishe 150–300 RMB/kg (Ibanga le-T300) |
| Amandla Aqondile | Okuphakathi (≈250) | Okuphezulu (≈600) |
| I-Modulus Ethile | Kuphansi Ngokulinganiselwe (≈20) | Okuphezulu (≈60-100) |
| Ukumelana Nomthelela | Okuphakathi (Ukuphuka okuphezulu kune-CFRP) | Kuphakeme kakhulu (Ukuqina okuhle) |
| Izindleko Zokucubungula | Amapuleti aqhekekile kulula ukuwacubungula, kodwa ukubumba okuyinkimbinkimbi kudinga izinqubo ezengeziwe. | Izindleko zokucindezela ukushisa kusengaphambili ziphezulu, kodwa zivumela ukubumba okuhlanganisiwe. |
| Ukuqina | Ukumelana okuhle nokukhathala, ukumelana okuhle kakhulu nokugqwala. | Ukusebenza kahle kakhulu kokukhathala, kodwa kudinga ukuvikelwa ekugqwaleni kwe-galvanic. |
| Ukunciphisa Isisindo | Ukwehla kwesisindo ngo-20–30% uma kuqhathaniswa ne-aluminium alloy. | Ukunciphisa isisindo ngo-40–50% uma kuqhathaniswa ne-aluminium alloy. |
Ukuhlaziywa Kwesimo Sokusebenza Kahle Kwezindleko
- Ama-drone abiza kancane abalulekile (isb. ukuhlolwa, ama-drone ezolimo): – Ama-BFRP angathatha indawo yezingxenye ezithile ze-aluminium alloy, ngezindleko eziphansi ngo-30-50% kune-CFRP kanye nokumelana nokugqwala okuphezulu, okunikeza ukusebenza kahle kwezindleko jikelele.
- Izinhlelo zokusebenza ezidinga ukuqina okuphezulu kanye nomklamo olula (isb., ama-drone okugijima, ama-drone ezithombe zasemoyeni): – I-CFRP inikeza inzuzo ebalulekile ekuguqukeni kokuguquguquka, inciphisa ukuguquguquka kwe-aerodynamic; yize ibiza kakhulu, ukusebenza kwayo akunakuthathelwa indawo.
- Izinhlelo zokusebenza ezinezidingo ezikhethekile zokusebenza: Uma kudingeka ukukhanya kwe-electromagnetic noma ukunciphisa ukudambisa/ukudlidliza, i-BFRP ingasebenza njengezinto ezengeziwe zezingxenye ezithile (isb., ama-radar domes).
- Izinselele Zobuchwepheshe kanye Neziqondiso Zokuthuthukisa
- Umklamo wesakhiwo esihlanganisiwe: Ama-laminate e-BFRP + CFRP: Endaweni ubeke i-carbon fiber ezindaweni ezinezidingo zokuqina okuphezulu ukuze kulinganiswe izindleko nokusebenza.
- Ukuthuthukiswa kwenqubo: Thuthukisa ama-prepreg e-BFRP noma izinto eziqiniswe nge-fiber eziphrintiwe nge-3D ukuze kuthuthukiswe ikhono lokwakha izakhiwo eziyinkimbinkimbi.
- Ubuchwepheshe bokujoyina: Sebenzisa amalunga ahlanganisiwe anezinti ezinamathelayo noma ukushisela nge-ultrasonic ukuze uthuthukise ukusebenza kahle kwamalunga.
Ngokusekelwe ekuhlaziyweni okungenhla, i-BFRP ifanele izakhiwo ezinomthwalo ophakathi kuya kophansi kuma-UAV amancane futhi inikeza inani lokusetshenziswa maqondana nokunciphisa isisindo, ukumelana nokugqwala, kanye nokunciphisa ukuminyana/ukudlidliza; noma kunjalo, kufanele igwenywe ezindaweni ezidinga ukuqina okuphezulu. Uma ukuqina kungeyona into ebalulekile kodwa izindleko ziyiyo, i-BFRP inikeza ukusebenza kahle kwezindleko okungcono kakhulu kune-CFRP.
Ngaphezu kwalokho, umklamo we-BFRP/CFRP hybrid ungacatshangelwa ukuthuthukisa izindleko.
Ukuhlaziywa kwe-Finite element (FEA) kungasetshenziswa futhi ukulingisa izingxenye ezithile (njenge-airframe), kuqhathaniswe isisindo kanye nezindleko ze-BFRP kanye ne-CFRP ngaphansi kwezici zokuphepha ezifanayo ukuze kuqhutshwe ukukhethwa kwezinto ngokusekelwe kudatha.
