Umahluko kuLwakhiwo kunye nokuVeliswa phakathi kweFilament Mat eqhubekayo kunye neStrand Mat eQiweyo

Izinto zokuqinisa ifayibha yeglasi, njengei-continuous filament mat (CFM)kwayeukhuko olunqunqiweyo (CSM), dlala indima ebalulekileyo kwimveliso edibeneyo. Ngelixa zombini zisebenza njengesiseko sezixhobo zenkqubo esekwe kwi-resin, iimpawu zabo zolwakhiwo kunye neendlela zokuvelisa zahluka kakhulu, ezikhokelela kwiingenelo zokusebenza ezahlukeneyo kwizicelo zamashishini.

1. I-Fiber Architecture kunye neNkqubo yokuVelisa

I-filament mat eqhubekayo yenziwei-fiber bundles engaphazamisekiyo, zidityaniswe kunye kusetyenziswa izibophelelo zeekhemikhali okanye iindlela zoomatshini. Ubume obuqhubekayo beefibers buqinisekisa ukuba i-mat igcina imicu emide, engapheliyo, idala inethiwekhi edibeneyo. Le mfezeko yolwakhiwo ivumela iimethi zefilament eziqhubekayo ukuba zimelane noxinzelelo lomatshini ngokufanelekileyo, zibenze zilungele.iinkqubo zokubumba zoxinzelelo oluphezulu. Ngokwahlukileyo, i-strand mat enqunqiweyo iquketheamafutshane, amacandelo efiber discreteisasazwe ngokungacwangciswanga kwaye idityaniswe ngomgubo okanye i-emulsion binders. Iintsinga ezingapheliyo zikhokelela kwisakhiwo esincinci, esibeka phambili ukukhululeka kokuphatha kunye nokulungelelanisa ngaphezu kwamandla akrwada.

2. Oomatshini kunye neNdlela yokuSebenza  

Ulungelelwaniso lwefayibha oluqhubekayo kwiCFM lubonelelaiimpawu ze-isotropic mechanicalngokuqina kokuqina okuphuculweyo kunye nokuxhathisa ukuhlamba iresin. Oku kuyenza ifaneleke ngokukodwaiindlela zokubumba ezivaliweyonjenge-RTM (i-Resin Transfer Molding) okanye i-SRIM (i-Structural Reaction Injection Molding), apho i-resin kufuneka ihambe ngokufanayo phantsi koxinzelelo ngaphandle kokukhupha iifayili. Ukukwazi kwayo ukugcina ukuzinza kwe-dimensional ngexesha lokufakwa kwe-resin kunciphisa iziphene kwiijometri eziyinkimbinkimbi. I-strand mat echotshiweyo, nangona kunjalo, iyagqwesangokukhawuleza i-resin saturationkunye nokuhambelana neemilo ezingaqhelekanga. Iintsinga ezimfutshane zivumela ukuphuma okumanzi ngokukhawuleza kunye nokukhululwa komoya okungcono ngexesha lokubeka isandla okanye ukubumba okuvulekileyo, okwenza kube yinto ekhethwayo kwizicelo ezilula, ezingabizi kakhulu njenge-bathware okanye iipaneli zemoto.

3. Isicelo-Izinto eziluncedo ezithile

Iimethi zefilament eziqhubekayo zenzelweimidibaniso yokusebenza okuphezuluifuna ukuqina, okufana nezixhobo ze-aerospace okanye iiblade zeinjini yomoya. Ukuchasana kwabo kwi-delamination kunye nokumelana nokudinwa okuphezulu kuqinisekisa ubomi obude phantsi kwemithwalo ye-cyclic. Iimethi ze-strand ezinqunqiweyo, kwelinye icala, zilungiselelweimveliso enkuluapho isantya kunye nokusebenza kakuhle kwezinto kubalulekile. Ubungqingqwa bawo obufanayo kunye nokuhambelana kweereyini ezahlukeneyo kubenza ukuba bafaneleke kwikhompawundi yokubumba amaphepha (SMC) okanye ukwenziwa kwemibhobho. Ukongeza, iimethi ze-strand ezinqunqiweyo zinokwenziwa ngokwezifiso kuhlobo lokuxinana kunye ne-binder ukuze zihambelane neemeko ezithile zokunyanga, ezinikezela ukuguquguquka kubavelisi.

Ukuqukumbela

Ukhetho phakathi kwemethi yefilament eqhubekayo kunye neemethi zomsonto onqunqiweyo zixhomekeke ekulinganiseni iimfuno zesakhiwo, isantya semveliso, kunye neendleko. Iimethi ze-filament eziqhubekayo zihambisa amandla angenakuthelekiswa nanto kwii-composites eziphambili, ngelixa ii-strand strand ezinqunqiweyo zibeka phambili ukuguquguquka kunye noqoqosho kwizicelo eziphezulu.
