Sengoloa sena se hlahloba liphapang tsa bohlokoa, melemo, mefokolo, le mekhoa e metle ea tšebeliso bakeng sa likhoele tse khaotsoeng le likhoele tse tsoelang pele. Qetellong, u tla ba le kutloisiso e hlakileng ea hore na ke mofuta ofe oa matlafatso o lumellanang le litlhoko tsa hau - ebang u ho etsa likoloi, lifofane, kaho, kapa boenjiniere ba likepe.

1. Likhoele tse khaotsoeng le likhoele tse tsoelang pele ke eng?

Likhoele tse khaotsoeng

Likhoele tse khaotsoengke likhoele tse khutšoane, tse arohaneng (hangata bolelele ba 3mm ho isa ho 50mm) tse entsoeng ka khalase, khabone, kapa thepa e 'ngoe e matlafatsang. Li hasanngoa ka mokhoa o sa reroang ka har'a matrix (joalo ka resin) ho fana ka matla, ho tiea le ho hanyetsa tšusumetso.

Tšebeliso e Tloaelehileng:

Metswako ea ho bopa maqephe (SMC)

Metswako ya ho bopa ka bongata (BMC)

Ho enta ka ente

Lisebelisoa tsa ho fafatsa

Likhoele tse Tsoelang Pele

Likhoele tse tsoelang peleke likhoele tse telele, tse sa robehang tse tsamaisang bolelele bohle ba karolo e kopaneng. Likhoele tsena li fana ka matla a holimo a ho thaepa le ho matlafatsa tsela.

Tšebeliso e Tloaelehileng:

Mekhoa ea ho putlama

Ho kobeha ha filament

Li-laminate tsa sebopeho

Likarolo tsa lifofane tse sebetsang hantle

2. Liphapang tsa Bohlokoa Pakeng tsa Likhoele tse Khaotsoeng le tse Tsoelang Pele

3. Melemo le Mathata

Likhoele tse khaotsoeng: Melemo le Mathata

✓ Melemo:

Ho bonolo ho sebetsana le tsona - E ka kopanngoa ka ho toba le li-resin.

Matlafatso e tšoanang - E fana ka matla mahlakoreng 'ohle.

E bolokang tjhelete – E fokotsa tshenyo le ho sebetsa ka tsela e bonolo.

E sebelisoa ka mekhoa e fapaneng - E sebelisoa lits'ebetsong tsa SMC, BMC, le spray-up.

✕ Mathata:

Matla a ho tsikinyeha a tlase ha a bapisoa le likhoele tse tsoelang pele.

Ha e lokele ho sebediswa bakeng sa dikopo tse nang le kgatello e phahameng (mohlala, mapheo a difofane).

Likhoele tse Tsoelang Pele: Melemo le Mathata

✓ Melemo:

Karolelano e phahameng ea matla ho ea boima - E loketse lifofane le likoloi.

Ho hanyetsa mokhathala hamolemo - Likhoele tse telele li aba khatello ea maikutlo ka katleho e kholo.

Tsela e ka fetoloang – Lifaeba li ka hlophisoa bakeng sa matla a holimo.

✕ Mathata:

E theko e boima haholo - E hloka tlhahiso e nepahetseng.

Ts'ebetso e rarahaneng - E hloka lisebelisoa tse khethehileng joalo ka li-filament winders.

4. Ke efe eo u lokelang ho e khetha?

Nako ea ho Sebelisa Likhoele Tse Khaotsoeng:

✔ Bakeng sa merero e nang le litšenyehelo tse tlase moo matla a phahameng a seng a bohlokoa.
✔ Bakeng sa dibopeho tse rarahaneng (mohlala, diphanele tsa dikoloi, thepa ya bareki).
✔ Ha matla a isotropic (a lekanang mahlakoreng 'ohle) a hlokahala.

Nako ea ho Sebelisa Likhoele tse Tsoelang Pele:

✔ Bakeng sa lits'ebetso tse sebetsang hantle (mohlala, lifofane, mahare a turbine ea moea).
✔ Ha ho hlokahala matla a tataiso (mohlala, methapo ea khatello).
✔ Bakeng sa ho tšoarella nako e telele tlas'a mojaro o potolohang.

5. Mekhoa ea Indasteri le Tebello ea Bokamoso

Tlhoko ea thepa e bobebe, e matla haholo e ntse e eketseha, haholo-holo likoloing tsa motlakase (li-EV), lifofaneng le matla a nchafatsoang.

Likhoele tse khaotsoengba bona tsoelo-pele ea thepa e sebelisitsoeng hape le li-resin tse thehiloeng linthong tsa tlhaho bakeng sa botsitso.

Likhoele tse tsoelang peleli ntse li ntlafatsoa bakeng sa ho beha fiber ka boiketsetso (AFP) le khatiso ea 3D.

Litsebi li bolela esale pele hore metsoako e kopantsoeng (e kopanyang likhoele tse khaotsoeng le tse tsoelang pele) e tla tuma haholo bakeng sa ho leka-lekanya litšenyehelo le ts'ebetso.

Qetello

Ka bobelilikhoele tse khaotsoeng'me likhoele tse tsoelang pele li na le sebaka sa tsona tlhahisong e kopaneng. Khetho e nepahetseng e itšetlehile ka tekanyetso ea projeke ea hau, litlhoko tsa ts'ebetso, le ts'ebetso ea tlhahiso.

Khethalikhoele tse khaotsoengbakeng sa ho matlafatsa isotropic ka mokhoa o theko e tlase.

Khetha likhoele tse sa khaotseng ha matla le ho tšoarella ho hoholo ho le bohlokoa.

Ka ho utloisisa liphapang tsena, baenjiniere le bahlahisi ba ka etsa likhetho tse bohlale tsa thepa, ba ntlafatsa ts'ebetso ea sehlahisoa le ts'ebeliso e ntle ea litšenyehelo.
