Tlhahlobo ea Maemo a Ts'ebetso ea Katleho ea Litšenyehelo
- Li-drone tsa bohlokoa tse theko e tlase (mohlala, tlhahlobo, li-drone tsa temo): – BFRP e ka nkela likarolo tse ling tsa alloy ea aluminium sebaka, ka litšenyehelo tse ka tlase ho 30-50% ho feta CFRP le ho hanyetsa mafome ho phahameng, e leng se fanang ka katleho e phahameng ea litšenyehelo ka kakaretso.
- Ditshebediso tse hlokang ho tiea ho hoholo le moralo o bobebe (mohlala, di-drone tsa mabelo, di-drone tsa ho nka difoto tsa moyeng): – CFRP e fana ka monyetla o moholo ho modulus ya ho tenyetseha, e fokotsang phetoho ya aerodynamic; leha e le theko e boima, tshebetso ya yona ha e nkelwe sebaka.
- Ditshebediso tse nang le ditlhoko tse ikgethang tsa tshebetso: Haeba ho hlokahala ponaletso ya motlakase kapa phokotso ya damping/vibration, BFRP e ka sebetsa e le thepa e tlatsetsang bakeng sa dikarolo tse itseng (mohlala, mathule a radar).
- Liphephetso tsa Tekheniki le Litaelo tsa Ntlafatso
- Moralo oa sebopeho se kopaneng: Li-laminate tsa BFRP + CFRP: Sebakeng seo u ka beha faeba ea khabone libakeng tse nang le litlhoko tse phahameng tsa ho tiea ho leka-lekanya litšenyehelo le ts'ebetso.
- Ntlafatso ea ts'ebetso: Hlahisa li-prepreg tsa BFRP kapa thepa e matlafalitsoeng ka fiber e hatisitsoeng ka 3D ho ntlafatsa bokhoni ba ho theha meaho e rarahaneng.
- Theknoloji ea ho kopanya: Sebelisa manonyeletso a kopantsoeng a nang le sekhomaretsi kapa ho tjheseletsa ka ultrasonic ho ntlafatsa katleho ea manonyeletso.
Ho latela tlhahlobo e kaholimo, BFRP e loketse meaho e mahareng ho isa ho e tlase ea mojaro ho li-UAV tse nyane mme e fana ka boleng ba ts'ebeliso mabapi le phokotso ea boima, ho hanyetsa mafome, le phokotso ea mongobo/ho thothomela; leha ho le joalo, e lokela ho qojoa libakeng tse hlokang ho tiea ho hoholo. Haeba ho tiea e se ntlha ea bohlokoa empa litšenyehelo li le teng, BFRP e fana ka katleho e ntle haholo ea litšenyehelo ho feta CFRP.
Ho phaella moo, moralo wa BFRP/CFRP o kopantsweng o ka nkuwa e le ho ntlafatsa ditjeo.
Tlhahlobo ea likarolo tse lekanyelitsoeng (FEA) e ka boela ea sebelisoa ho etsisa likarolo tse itseng (joalo ka sefofane sa moea), ho bapisa boima le litšenyehelo tsa BFRP le CFRP tlas'a lintlha tse tšoanang tsa polokeho ho khanna khetho ea thepa ho latela lintlha.
