Kugona Kushandisa Basalt Fiber kuZvivako Zvidiki zveUAV
Pfupiso yeZvinhu zve Basalt Fiber Yakasimbiswa Polymer (bfrp)
Tichitora jira rakapwanyika rine ukobvu hwe5 mm semuenzaniso, maparamita aro epanyama akajairika ndeaya anotevera: - Simba rekudhonza: ≥500 MPa
- Modulus yekusimba: ≥40 GPa
- Kuwanda: 1.8–2.0 g/cm³
- Kureba panguva yekuzorora: 2.5–3.0%
- Kuramba Kuora: Yakanaka kwazvo (inodzivirira acids, alkalis, uye UV mwaranzi)
- Kuwedzerwa kwemafuta muchiyero chenguva dzose: Zvakafanana nekongiri; kushanda zvakanaka pakupisa kwakaderera
Kuongorora Kushanda KwemaUAV Madiki
- Zvakanakira
- Kugona kuderedza huremu: Nekuwanda kwayo kwakaderera pane kwearuminiyamu (2.7 g/cm³), inoita kuti huremu huderere, nokudaro ichivandudza kutsungirira kwekubhururuka uye kufamba-famba.
- Simba rakati uye modulus chaiyo: Simba rakati (simba/huremu): ≈250–280 MPa·cm³/g, iri nani pane aruminiyamu alloy (≈140) asi yakaderera pane carbon fiber (≈600).
- Modulus chaiyo (modulus/density): ≈20–22 GPa·cm³/g, inoenzaniswa nealuminium alloy asi chikamu chimwe chete muzvitatu checarbon fiber.
- Hunhu hwekudzima damping: Yakakwira damping coefficient kupfuura carbon fiber, inoderedza kudengenyeka kwekubhururuka uye inovandudza kugadzikana kwesensa. • Kujeka kwemagetsi: Haikanganisi masaini ekutaurirana, zvichiita kuti ive yakakodzera nzvimbo dzeradar kana antenna.
- Kusapindirana kwezvakatipoteredza: Kusapindirana nekupisa kwakanyorova uye ngura, kwakakodzera maUAV munzvimbo dzegungwa kana dzemaindasitiri.
- Zvikumbiro Zvinokurudzirwa
- Zvivako zvinotakura zvinhu zviri pakati nepakati kusvika pasi: Mafuremu efuselage, zvinotsigira zvekumhara, mbabvu dzemapapiro.
- Zvinhu zvisingatakuri mutoro: MaAntena mounts, matireyi emabhatiri, ma sensor housings.
- Zvikamu zvenzvimbo dzakakosha: Zvikamu zvakasangana nemishonga yezvipembenene paUAV dzekurima, matumba eUAV dzemugungwa.
Kuenzanisa Kwemutengo-Kushanda neCarbon Fiber (CFRP)
Kuenzanisa: Basalt Fiber (BFRP) vs. Carbon Fiber (CFRP)
| Chiyero | Basalt Fiber Reinforced Polymer (BFRP) | Kabhoni Fiber Yakasimbiswa Polymer (CFRP) |
| Mutengo weZvinhu | Maplate: anenge 60–100 RMB/kg (Yemumba) | Maplate: anenge 150–300 RMB/kg (T300 Giredhi) |
| Simba Rakananga | Pakati nepakati (≈250) | Yakakwira (≈600) |
| Modulus chaiyo | Yakaderera Zvishoma (≈20) | Yakakwira (≈60-100) |
| Kuramba Kukanganisa | Pakati nepakati (Kuomarara kwakanyanya kupfuura CFRP) | Yakakwirira Zvishoma (Kusimba kwakanaka) |
| Mutengo wekugadzirisa | Maplate akapwanyika ari nyore kugadzirisa, asi kuumba kwakaoma kunoda mamwe maitiro ekuwedzera. | Mutengo wekushandisa prepreg hot-pressing wakakwira, asi unobvumidza kuumbwa kwakabatana. |
| Kugara kwenguva refu | Kuramba kuneta kwakanaka, kuramba ngura kwakanaka. | Kushanda zvakanaka kwazvo pakuneta, asi kunoda dziviriro kubva mukuora kwegalvanic. |
| Kuderedza Huremu | Kuderedzwa kwehuremu ne20–30% zvichienzaniswa nearuminiyamu. | Kuderedzwa kwehuremu ne40–50% zvichienzaniswa nearuminiyamu. |
Kuongorora Mamiriro Ezvinhu Nekushanda Kwemari
- Madrone anodhura zvishoma (semuenzaniso, kuongorora, madrone ekurima): – BFRP inogona kutsiva zvimwe zvikamu zvealuminium alloy, nemitengo yakaderera ne30–50% pane CFRP uye inodzivirira ngura zvakanyanya, zvichipa kushanda zvakanaka kwemari.
- Mashandisirwo anoda kuomarara kwakanyanya uye dhizaini yakareruka (semuenzaniso, madrone ekumhanya, madrone ekutora mifananidzo yemuchadenga): - CFRP inopa mukana wakakura mukuchinja kwesimba, ichideredza kushanduka kwemhepo; kunyangwe ichidhura zvakanyanya, mashandiro ayo haatsiviwi.
- Mashandisirwo ane zvinodiwa zvakakosha zvekushanda: Kana kujeka kwemagetsi kana kuderedza kupfava/kudedera kwekudengenyeka kuchidikanwa, BFRP inogona kushanda sechishandiso chekuwedzera kune zvimwe zvikamu (semuenzaniso, radar domes).
- Matambudziko eUnyanzvi uye Mirayiridzo yeKugadzirisa
- Dhizaini yechivakwa chehybrid: BFRP + CFRP laminates: Isa carbon fiber munzvimbo dzine zvinodiwa zvekuomarara zvakanyanya kuti mutengo uye mashandiro azvo zvienzane.
- Kuvandudzwa kwemaitiro: Gadzira maBFRP prepregs kana zvinhu zvakadhindwa ne3D zvakasimbiswa nefiber kuti zviwedzere kugona kuumba zvivakwa zvakaoma.
- Tekinoroji yekubatanidza: Shandisa majoini ane jira rinonamira kana welding ye ultrasonic kuti uvandudze kushanda zvakanaka kwemajoini.
Zvichibva paongororo iri pamusoro apa, BFRP yakakodzera zvivakwa zvine mutoro uri pakati nepakati kusvika pasi muUAV diki uye inopa kukosha kwekushandiswa maererano nekuderedza huremu, kuramba ngura, uye kuderedza damping/vibration; zvisinei, inofanira kudzivirirwa munzvimbo dzinoda kuomarara kwakanyanya. Kana kuomarara kusiri chinhu chakakosha asi mutengo uripo, BFRP inopa kushanda kuri nani pamutengo kupfuura CFRP.
Pamusoro pezvo, dhizaini yeBFRP/CFRP hybrid inogona kutariswa senzira yekugadzirisa mitengo.
Kuongororwa kweFinite element (FEA) kunogonawo kushandiswa kutevedzera zvikamu zvakati (zvakadai se airframe), kuenzanisa huremu nemutengo weBFRP neCFRP pasi pezvinhu zvakaenzana zvekuchengetedza kuti zvitungamirire kusarudzwa kwezvinhu zvichibva padata.
