Uvavanyo lokumelana neempembelelo zemathiriyeli edibeneyo
1. Indlela yokuvavanya impembelelo yesantya esisezantsi
Ukuze ukulinganisa ukuziphatha kwempembelelo yezinto phantsi kweemeko zangempela, abaphandi bacebise inani elikhulu leendlela zokulinga.Ngokweyona meko yempembelelo, impembelelo ngokubanzi yahlulahlulwe ibe yimpembelelo yesantya esiphezulu kunye nesantya esisezantsi.
Impembelelo yesantya esiphezulu ikwabizwa ngokuba yi-ballistic impact.Ngenxa yokuba impembelelo yesantya esiphezulu ifumene ingqwalasela ebalulekileyo kwi-aerospace kunye nemimandla yasemkhosini, abantu baye baqhuba uphando oluninzi lovavanyo kwimpembelelo yesantya esiphezulu.Impembelelo enesantya esiphezulu ihlala isebenzisa iprojectile encinci ukubetha izinto ngesantya esiphezulu, kwaye ikakhulu isebenzisa imipu yomoya ukuqalisa iiprojectiles ukufundisisa isantya esiphezulu sokuziphatha kwezixhobo ezihlanganisiweyo, njengoko kubonisiwe kumfanekiso:
Uvavanyo lwempembelelo yesantya esisezantsi ludla ngokulinganisa impembelelo yento enobunzima obukhulu kumphezulu wezinto ngesantya esisezantsi, njengokuhla ngengozi kwesixhobo ngexesha lokulungiswa, kunye nesixhobo sokuvavanya ubunzima siqhele ukusetyenziselwa uvavanyo. ukulinganisa.
Umzobo 2 Drop isixhobo sokuvavanya isando
Iziphumo zophando zibonisa ukuba imilo, umgangatho kunye nesantya seprojekthi iya kuba nempembelelo enkulu kwindlela yokungaphumeleli kwezinto ezidibeneyo.Ngokomzekelo, abaphandi baye benza uphando oluninzi malunga nobudlelwane phakathi kobume bentloko yehamile kunye nempembelelo yokuziphatha kwezinto ezidibeneyo.Ngokuqhelekileyo, xa kusetyenziswa intloko yehamile ngokubukhali, ubuninzi bomonakalo wempembelelo yendawo yendawo, kunye neyona ndlela yokungaphumeleli engundoqo itshintsha ukusuka kwi-delamination ukuya kwi-matrix ukusilela kunye nomonakalo.Ifayibha ikhefu.
2. Impembelelo yeemeko zokusingqongileyo ekusebenzeni kwempembelelo enesantya esiphantsi
Amalungu olwakhiwo oludibeneyo kufuneka abe neziphumo ezinzima zokusingqongileyo ngexesha lokusetyenziswa kwexesha elide, njengobushushu obuphezulu, ubushushu obuphantsi, ubushushu obumanzi, kunye nemijikelo yobushushu.Uphononongo lubonise ukuba phantsi kwezenzo zale mimandla, iimpawu zemishini yezinto ezidibeneyo ziya kutshintsha kakhulu.Ukuhamba ngebhayisikile nge-thermal ngokuqhelekileyo kunciphisa ukugoba kunye nokuguquguquka kwamandla e-tensile yemathiriyeli edibeneyo, kwaye ivelise inani elikhulu le-microcracks kwi-matrix.
Ikakhulu sebenzisa ukunyangwa kwangaphambili kokusingqongileyo kunye novavanyo lokulinganisa kokusingqongileyo ukufunda ifuthe leempembelelo zokusingqongileyo.Into ebizwa ngokuba yi-pretreatment yokusingqongileyo kukubeka imathiriyeli edibeneyo ukuze ivavanywe kwindawo ethile ukuze iqhutywe kwangaphambili, kwaye emva koko ibeka izinto ezicwangcisiweyo kuvavanyo lwempembelelo yesantya esisezantsi kwiqondo lokushisa.Uvavanyo lokulinganisa lokusingqongileyo kukubeka izinto ezidibeneyo kwigumbi lokusingqongileyo ngelixa uchaphazela.Le ndlela isetyenziselwa ukufunda ukusebenza kwempembelelo yamacandelo kwiindawo ezahlukeneyo zenkonzo.
3. Impembelelo yezinto eziphathekayo ekusebenzeni kwempembelelo yesantya esisezantsi
I-Fiber isetyenziswa ngokubanzi njengokuqinisa kwimveliso yezinto ezidibeneyo.Kwangaxeshanye, njengowona mthwalo uphambili womthwalo, ukusebenza kwefiber kunempembelelo enkulu ekuchaselweni kwempembelelo epheleleyo yezinto ezidibeneyo.Imicu esetyenziswa kwishishini le-aerospace ikakhulu ibandakanyacarbon fiber, ifayibha yeglasikunye neKevlar fiber.Ngenxa yobuqhophololo obukhethekileyo befayibha yekhabhoni, ukuxhathisa kwekhabhoni ifayibha eyomeleziweyo yeresin matrix komdibaniso buthathaka kunoko kwefiber yeglasi kunye nefiber yeKevlar.
I-matrix ye-fiber-reinforced resin-based composite materials idlala indima ebaluleke kakhulu kwizinto ezidibeneyo.I-matrix ye-resin ayinakwahlulwa nokuba ihambisa umthwalo, igcine ukuqhelaniswa neentsinga okanye ukugcina ingqibelelo yezinto.Iziphumo zophononongo zibonisa ukuba nangona iipropathi zoomatshini be-thermosetting resins zingcono kunezo ze-thermoplastic resins, i-cross-linked molecular structure ye-thermosetting resins ibenza bangabi nzima, nto leyo eyenza ukuba bangaphumeleli ngakumbi phantsi komthwalo wempembelelo.
I-interface idlala indima yokudlulisa umthwalo kwifiber kwizinto ezidibeneyo, ngoko ke ukusebenza kwe-interface kuya kuchaphazela ukusebenza ngokubanzi kwezinto ezidibeneyo.Izinto ezidityanisiweyo ezinonxibelelwano olulambathayo phakathi kwefiber kunye ne-matrix ziya kubonisa amandla asezantsi kunye nokuqina, kwaye i-Bonding eyomeleleyo kakhulu iya kwenza ukuba izinto zibe brittle.
