Ilaphu le-Checkered aliyi-twist roving plain ilaphu, sisixhobo esisisiseko esibalulekileyo sesandla - coma i-FRP.Amandla e-gingham ikakhulu kwicala le-warp kunye ne-weft yelaphu.Ngezihlandlo ezifuna i-warp ephezulu okanye ukomelela kwe-weft, inokulukwa ibe yindlela enye ye-gingham, enokucwangciswa kwi-warp okanye i-weft ejikelezayo ngakumbi.
Iimfuno zomgangatho we-gingerbread zimi ngolu hlobo lulandelayo: ①Ilaphu liyunifomu, isiphelo sithe tye, umphezulu usicaba kwaye uphothiwe, kwaye akukho mabala, ifuzz, ukushwabana okanye ukushwabana;② Ubuninzi be-Wap kunye ne-weft, ubunzima bendawo, ububanzi belaphu kunye nobude bomqengqelezi buhambelana nomgangatho;③ Ukujija kumbindi wephepha eliqinileyo, ukujija ngokucocekileyo;④ Ukugqithiswa kwe-resin ngokukhawuleza kunye nokulungileyo;⑤ Amandla omatshini owomileyo kunye nomanzi ee-laminates ezenziwe ngelaphu kufuneka ahlangabezane neemfuno.
Iimpawu ze-composite ezityatyekwe ngelaphu le-plaid amandla aphantsi okucheba i-interlaminar kunye noxinzelelo olubi kunye namandla okudinwa.
I-Fiberglass sheet evezwe
(1) Sika umsonto osikiweyo: sika umsonto weglasi (ngamanye amaxesha ungaphoswanga) ube yi-50mm ubude, uwasasaze ngokungacwangciswanga kodwa ngokulinganayo kwibhanti elinomnatha, emva koko sebenzisa isibophelelo se-emulsion okanye isibophelelo sokufefa somgubo, ukunyanga ubushushu kunye nebhondi kumsonto osikiweyo. .Ukusika ukuziva kusetyenziswa ikakhulu kwintlama yesandla, ukwenza ipleyiti eqhubekayo kunye noxinzelelo lokufa kunye nenkqubo ye-SMC.Iimfuno zomgangatho womsonto osikiweyo zivakala ngolu hlobo lulandelayo: ① umgangatho wendawo ufana kwicala lobubanzi;②I-filament esikiweyo yasasazwa ngokulinganayo kwindawo evakalelwayo, akukho mingxunya emikhulu eyenziwe, kwaye i-binder yasasazwa ngokulinganayo.③ ukomelela okuphakathi kokomileyo;④ Ukungena kakuhle kwe-resin kunye nokungena.
(2) Ukuziva ekrwada okuqhubekayo: iglasi yesilika ekrwada eyenziwe kwinkqubo yokuzoba okanye isilika ekrwada eqhubekayo etsalwa kumbhobho wesilika ekrwada isasazeke kwibhanti eqhubekayo eshukumayo yomnatha kumfanekiso 8, kwaye isibophelelo somgubo sidityaniswe kunye.I-fiber ye-fiberglass fibril mat eqhubekayo iyaqhubeka, ngoko ke impembelelo yayo yokomeleza kwizinto ezidibeneyo ingcono kune-cut fiberglass mat.Isetyenziswa kakhulu kwinkqubo ye-pultruding, i-RTM, ingxowa yoxinzelelo kunye neglasi yaziva iplastiki ye-thermal eqinisiweyo (GMT).
3Kuba olu hlobo lokuziva lwenziwe ngeglasi yealkali ephakathi (C), inika ukuxhathisa kweekhemikhali ze-FRP, ngakumbi ukumelana ne-asidi.Kwangaxeshanye, ngenxa yokuba imvakalelo ibhityile kwaye idiameter yefiber yeglasi incinci, inokufunxa iresin eninzi ukwenza umaleko otyebileyo weresin, ogqume ukhozo lwegilasi yezinto eziqinisiweyo (ezifana nelaphu leplaid), kwaye udlale indima yokuguqulwa komphezulu.
(4) Ukuvalelwa kwenaliti: idayiwe inaliti okanye yahlulwe yaba lusinga olufutshane oludityanisiweyo kunye nesilika ekrwada ekrwada enenaliti.Ifayibha eyi-Staple fibre enenaliti eyenziwe ngokusika ifayibha yeglasi ijikeleza ibe ngamaqhekeza angama-50mm kwaye ngokungenamkhethe uwabeke kwi-substrate ebekwe kwangaphambili kwibhanti lokuhambisa.Emva koko iinaliti ezineebhabhu zisetyenziselwa inaliti i-fibers staple kwi-substrate, ngelixa i-crochet ihoxa ezinye iifibers ukuze zenze isakhiwo se-three-dimensional.Izinto ezisisiseko zinokuba yifayibha yeglasi okanye enye ilaphu lefayibha ebhityileyo, olu hlobo lwenaliti luvakala lunovakalelo olungephi.Usetyenziso lwayo oluphambili lubandakanya izinto zokufudumeza ubushushu, izinto zokucoca ubushushu, izinto zokucoca, kwaye zingasetyenziselwa ukuveliswa kwe-FRP, kodwa amandla e-FRP aphantsi, ububanzi bokusetyenziswa bulinganiselwe.Olunye uhlobo oluqhubekayo lwefilament ephambili enaliti ezivalwayo lulwakhiwo olunemigangatho emithathu yokuvakala apho iglasi eqhubekekayo intambo ephambili iphoswa ngokungacwangciswanga kwibhanti yomnatha eqhubekayo ngesixhobo sokujula ngocingo kwaye ifakwe ngepleyiti yenaliti.Olu hlobo lokuziva lusetyenziswa ikakhulu kwimveliso yefiber yeglasi eyomelezwe ngamashiti anesitampu se-thermoplastic.
5Eyangaphambili inokungena endaweni yesibophelelo esisikiweyo esidityanisiweyo esivakele kusetyenziso oluninzi, kwaye le yokugqibela inokutshintsha ifayibha ekrwada eqhubekayo ivakale ukuya kumlinganiselo othile.Iinzuzo zabo eziqhelekileyo azikho i-binder, zigweme ukungcola kwenkqubo yokuvelisa, ngexesha elifanayo, ukungena kakuhle, ukubopha ukusebenza, ixabiso eliphantsi.
