Ukusetshenziswa kwezindwangu ze-glass fibre composite ku-RTM kanye nenqubo yokufaka i-vacuum

Izindwangu ze-Glass fiber compositeasetshenziswa kabanzi ku-RTM (Resin Transfer Molding) kanye nezinqubo zokumnika i-vacuum, ikakhulukazi kulezi zici ezilandelayo:

1. Ukusetshenziswa kwezindwangu ze-glass fibre composite kunqubo ye-RTM
Inqubo ye-RTM iyindlela yokubumba laphoinhlakaijovelwa esikhunjeni esivaliwe, futhi i-fiber preform iyafakwa futhi iqiniswe ukugeleza kwe-resin. Njengento eqinisayo, izindwangu zengilazi ze-fiber composite zidlala indima ebalulekile kwinqubo ye-RTM.

1. (1) Umthelela wokuqinisa: Izindwangu ze-Glass fibre composite zingathuthukisa ngempumelelo izakhiwo zemishini zezingxenye ezibunjiwe ze-RTM, njengamandla aqinile, amandla okugoba nokuqina, ngenxa yamandla azo aphezulu nezici eziphezulu ze-modulus.
2. (2) Ukujwayela izakhiwo eziyinkimbinkimbi: Inqubo ye-RTM ingakha izingxenye ezinobumo obuyinkimbinkimbi nezakhiwo. Ukuguquguquka nokuklama kwezindwangu ze-glass fiber composite kwenza ukuthi ivumelane nezidingo zalezi zakhiwo eziyinkimbinkimbi.
3. (3) Izindleko zokulawula: Uma kuqhathaniswa nezinye izinqubo zokubumba eziyinhlanganisela, inqubo ye-RTM ehlanganiswe nezindwangu ze-glass fiber composite inganciphisa izindleko zokukhiqiza ngenkathi iqinisekisa ukusebenza, futhi ifanele ukukhiqizwa okukhulu.

2. Ukusetshenziswa kwendwangu yengilazi ye-fiber composite inqubo yokufaka i-vacuum
Inqubo yokufaka i-vacuum (okubandakanya i-VARIM, njll.) iyindlela yokumithisaindwangu ye-fiberizinto zokuqinisa emgodini wesikhunta esivaliwe ngaphansi kwezimo ze-vacuum negative ngokusebenzisa ukugeleza nokungenainhlaka, bese elapha futhi ebumba. Indwangu ye-Glass fiber composite nayo isetshenziswa kabanzi kule nqubo.

• (1) Umthelela wokumila: Ngaphansi kwengcindezi ye-vacuum negative, inhlaka ingagxilisa ngokugcwele indwangu ehlanganisiwe ye-fiber yengilazi, inciphise izikhala nokukhubazeka, futhi ithuthukise ukusebenza okuphelele kwezingxenye.
• (2) Ijwayelanisa nogqinsi olukhulu nezingxenye zikasayizi omkhulu: Inqubo yokufaka i-vacuum inemikhawulo embalwa kusayizi nokuma komkhiqizo, futhi ingasetshenziselwa ukubumba ukushuba okukhulu kanye nezingxenye zesakhiwo ezinosayizi omkhulu, njengama-wind turbine blades, ama-hulls, njll. Indwangu ye-Glass fiber composite, njengento eqinisayo, ingahlangabezana nezidingo zamandla nokuqina zalezi zingxenye.
• (3) Ukuvikelwa kwemvelo: Njengobuchwepheshe bokubumba obuvaliwe, ngesikhathi sokubumbainhlakaukumnika kanye nenqubo yokwelapha yenqubo yokufaka i-vacuum, izinto eziguquguqukayo kanye nezinto ezingcolisa umoya ezinobuthi zivalelwe ifilimu yesikhwama se-vacuum, enomthelela omncane emvelweni. Njengento eqinisayo engangcoliswanga, indwangu yengilazi ye-fiber composite ithuthukisa ukuvikelwa kwemvelo kwenqubo.

3. Izibonelo eziqondile zohlelo lokusebenza

• (1) Emkhakheni we-aerospace, izindwangu eziyinhlanganisela ye-fiber yengilazi ehlanganiswe ne-RTM kanye nenqubo yokufaka i-vacuum ingasetshenziswa ukwenza umsila omile wendiza, iphiko langaphandle nezinye izingxenye.
• (2) Embonini yokwakha umkhumbi, izindwangu ezihlanganisiwe ze-glass fibre zingasetshenziswa ukwenza ama-hulls, amadekhi nezinye izingxenye zesakhiwo.
• (3) Emkhakheni wamandla omoya, izindwangu ezihlanganisiwe ze-glass fiber zisetshenziswa njengezinto zokuqinisa futhi zihlanganiswe nenqubo yokufaka i-vacuum ukuze kukhiqizwe izindwani ezinkulu ze-turbine yomoya.

Isiphetho
Izindwangu ze-Glass fiber composite zinamathemba abanzi okusebenza kanye nenani elibalulekile ku-RTM kanye nezinqubo zokufakwa kwe-vacuum. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwenza kahle okuqhubekayo kwezinqubo, ukusetshenziswa kwezindwangu ze-glass fiber composite kulezi zinqubo ezimbili zizoba ziningi futhi zijule.
