I-Resin Transfer Molding Process (RTM)
1. Incazelo yendlela: Imicu eyomile ibekwe esikhunjeni esingaphansi, esingacindezelwa ngaphambili ukuze senze imicu ifanelane nokubunjwa kwesikhunta ngangokunokwenzeka futhi iboshwe ngokunamathela; khona-ke, isikhunta esingaphezulu sigxilwe esikhunjeni esingaphansi ukuze sakhe umgodi, bese i-resin ijova emgodini. Umjovo we-resin osizwa ngevacuum kanye nokungena kwemicu, okwaziwa ngokuthi Umjovo we-Vacuum-Assisted Resin (VARI), uvame ukusetshenziswa. Uma ukufakwa kwe-fiber sekuqediwe, i-valve yesingeniso se-resin ivaliwe futhi inhlanganisela iyaphulukiswa. Umjovo we-resin kanye nokwelashwa kungenziwa ekamelweni lokushisa noma ngaphansi kwezimo ezishisayo.
2. Ukukhethwa Kwezinto:
I-resin: ngokuvamile i-epoxy, i-polyester, i-polyvinyl ester ne-phenolic resin, i-bismaleimide resin ingasetshenziswa ekushiseni okuphezulu.
I-Fiber: akukho mfuneko. I-fiber ethungiwe ifaneleka kakhulu kule nqubo, ngoba igebe phakathi kwe-fiber bundle livumela ukudluliswa kwe-resin; kukhona imicu ethuthukiswe ngokukhethekile engakhuthaza ukugeleza kwe-resin
Izinto eziyinhloko: i-foam yeselula ayifanele, ngoba amangqamuzana e-honeycomb azogcwaliswa nge-resin, futhi ukucindezela kuzophinde kubangele ukugoqa kwegwebu.
3. izinzuzo eziyinhloko:
(1) Ingxenye ephezulu yevolumu ye-fiber, i-porosity ephansi
(2) Impilo nokuphepha, indawo yokusebenza ehlanzekile futhi ehlelekile njengoba inhlaka ivalwe ngokuphelele.
(3) Yehlisa ukusetshenziswa kwezisebenzi
(4) Izinhlangothi ezingenhla nezingezansi zezingxenye zesakhiwo ziyizindawo ezibunjiwe, okulula ukwelashwa okungaphezulu okulandelayo.
4. Okubi kakhulu:
(1) Isikhunta esisetshenziswa ndawonye siyabiza, siyasinda futhi sikhulu ukuze simelane nokucindezela okukhulu.
(2) kuphela ekwenziweni kwezingxenye ezincane
(3) Izindawo ezingafakwanga zingenzeka kalula, okubangela inani elikhulu lezinsalela
5. Izinhlelo zokusebenza ezijwayelekile: i-shuttle yasemkhathini encane neyinkimbinkimbi nezingxenye zemoto, izihlalo zesitimela.
