Umehluko Wesakhiwo Nokukhiqiza Phakathi Kwe-Filament Mat Eqhubekayo kanye Ne-Chopped Strand Mat

I-Glass fiber reinforcement materials, njengei-continuous filament mat (CFM)futhii-chopped strand mat (CSM), dlala indima ebalulekile ekukhiqizeni okuyinhlanganisela. Ngenkathi zombili zisebenza njengesisekelo sezinqubo ezisekelwe ku-resin, izici zazo zesakhiwo nezindlela zokukhiqiza zehluka kakhulu, okuholela ezinhlelweni zokusebenza ezihlukile ezinhlelweni zemboni.

1. I-Fiber Architecture kanye Nenqubo Yokukhiqiza

I-filament mat eqhubekayo yakhiweama-fiber bundles aqondiswe ngokungahleliwe kodwa angaphazamiseki, ehlanganiswe ndawonye kusetshenziswa izibophezelo zamakhemikhali noma izindlela zemishini. Imvelo eqhubekayo yemicu iqinisekisa ukuthi umata ugcina izintambo ezinde, ezinganqamuki, okwenza inethiwekhi ehlangene. Lokhu buqotho besakhiwo kuvumela ama-filament mats aqhubekayo ukuthi amelane nezingcindezi zemishini ngokuphumelelayo, okuwenza alungeleizinqubo zokubumba ezinomfutho ophezulu. Ngokuphambene, i-strand mat eqoshiwe iquketheama-fiber amafushane, amasegimenti ahlukenekusatshalaliswa ngokungahleliwe futhi kuhlanganiswe nezibophezelo eziyimpuphu noma ze-emulsion. Imicu engaqhubeki iphumela esakhiweni esingaqinile kancane, esibeka phambili ukuphatheka kalula nokuvumelana nezimo kunamandla aluhlaza.

2. Mechanical and Processing Performance  

Ukuqondanisa kwefayibha okuqhubekayo ku-CFM kunikezaizakhiwo zemishini ye-isotropicngamandla okuqina athuthukisiwe kanye nokumelana ne-resin washout. Lokhu kuyenza ifaneleke ikakhulukaziamasu esikhunta esivaliwenjenge-RTM (I-Resin Transfer Molding) noma i-SRIM (I-Structural Reaction Injection Molding), lapho inhlaka kufanele igeleze ngokufanayo ngaphansi kwengcindezi ngaphandle kokukhipha imicu. Amandla ayo okugcina ukuzinza kwe-dimensional ngesikhathi sokufakwa kwe-resin kunciphisa amaphutha kumajometri ayinkimbinkimbi. I-strand mat eqoshiwe, nokho, ihamba phambiliukugcwala kwe-resin ngokusheshakanye nokuvumelana nezimo ezingajwayelekile. Izintambo ezimfishane zivumela ukuphuma komoya okusheshayo nokuphuma komoya okungcono ngesikhathi sokumiswa kwesandla noma ukubunjwa okuvulekile, okukwenza kube ukukhetha okuncanyelwayo kwezinhlelo zokusebenza ezilula, ezizwelayo ezibizayo njenge-bathware noma amaphaneli ezimoto.

3. Izinzuzo eziqondene nohlelo lokusebenza

Ama-filament mats aqhubekayo aklanyelweizinhlanganisela ezisebenza kahle kakhuluedinga ukuqina, njengezingxenye ze-aerospace noma ama-wind turbine blades. Ukumelana kwabo ne-delamination kanye nokumelana nokukhathala okuphezulu kuqinisekisa ukuphila isikhathi eside ngaphansi kwemithwalo ye-cyclic. Ngakolunye uhlangothi, ama-strand mats aqoshiwe alungiselelweukukhiqizwa ngobuningilapho isivinini kanye nokusebenza kahle kwezinto kubalulekile. Ubukhulu bawo obufanayo kanye nokuhambisana nama-resin ahlukahlukene kuwenza alungele ukubumba amashidi (i-SMC) noma ukukhiqizwa kwamapayipi. Ukwengeza, ama-strand mats aqotshiwe angenziwa ngendlela oyifisayo kuhlobo lokuminyana kanye ne-binder ukuze avumelane nezimo ezithile zokuphulukisa, okunikeza ukuguquguquka kwabakhiqizi.

Isiphetho

Ukukhetha phakathi kwe-filament mat eqhubekayo kanye nomata bomucu osikiwe kuncike ekulinganiseni izidingo zesakhiwo, isivinini sokukhiqiza, kanye nezindleko. Omata be-filament abaqhubekayo baletha amandla angenakuqhathaniswa ezinhlanganisela ezithuthukisiwe, kuyilapho ama-strand aqoshiwe abeka phambili ukuguquguquka nomnotho ezinhlelweni zevolumu ephezulu.
