Ukuhlolwa kokumelana nomthelela wezinto eziyinhlanganisela
1. Indlela yokuhlola umthelela wesivinini esiphansi
Ukuze kulingise ukuziphatha komthelela wezinto ezisetshenziswayo ngaphansi kwezimo zangempela, abacwaningi bahlongoze inani elikhulu lezindlela zokuhlola.Ngokwesimo sangempela somthelela, umthelela ngokuvamile uhlukaniswa ngomthelela wesivinini esiphezulu kanye nomthelela wesivinini esiphansi.
Umthelela wejubane eliphezulu ubizwa nangokuthi umthelela we-ballistic.Ngenxa yokuthi umthelela wesivinini esiphezulu uthole ukunakwa okubalulekile emkhakheni we-aerospace nezempi, abantu benze ucwaningo oluningi lokuhlola ngomthelela wesivinini esikhulu.Umthelela wesivinini esikhulu ngokuvamile usebenzisa i-projectile encane ukushaya into ngesivinini esiphezulu, futhi ikakhulukazi usebenzisa izibhamu zomoya ukwethula ama-projectile ukuze kufundwe ukuziphatha komthelela wesivinini esikhulu wezinto eziyinhlanganisela, njengoba kuboniswe esithombeni:
Ukuhlolwa komthelela wesivinini esiphansi kuvame ukulingisa umthelela wento enesisindo esikhulu ebusweni bento ngesivinini esiphansi, njengokwehla ngephutha kwethuluzi ngesikhathi sokulungiswa, kanye nedivayisi yokuhlola isisindo ngokuvamile isetshenziselwa ukuhlola. ukulingiswa.
Umfanekiso 2 Drop idivayisi yokuhlola isando
Imiphumela yocwaningo ibonisa ukuthi ukuma, ikhwalithi kanye nesivinini se-projectile kuzoba nomthelela omkhulu endleleni yokwehluleka kwezinto ezihlanganisiwe.Isibonelo, abacwaningi benze ucwaningo oluningi ngobudlelwano phakathi komumo wekhanda lesando kanye nokuziphatha komthelela wezinto eziyinhlanganisela.Ngokuvamile, lapho kusetshenziswa ikhanda lesando libukhali, yilapho uhla lomonakalo womthelela lwenziwa ngokwendawo, futhi imodi yokwehluleka eyinhloko ishintsha ukusuka ku-delamination ukuya ekuhlulekeni kwe-matrix kanye nokulimala.I-Fiber iyaphuka.
2. Umthelela wezici zemvelo ekusebenzeni komthelela wesivinini esiphansi
Izingxenye zesakhiwo esihlanganisiwe kufanele zithole imiphumela eyinkimbinkimbi yemvelo ngesikhathi sokusetshenziswa kwesikhathi eside, njengezinga lokushisa eliphezulu, izinga lokushisa eliphansi, ukushisa okumanzi, nemijikelezo yokushisa.Ucwaningo luye lwabonisa ukuthi ngaphansi kwesenzo salezi zindawo, izakhiwo zemishini yezinto ezihlanganisiwe zizoshintsha kakhulu.Ukuhamba ngebhayisikili okushisayo ngokuvamile kunciphisa amandla okugoba nawokuguquguquka okuqinile kwezinto eziyinhlanganisela, futhi kukhiqiza inani elikhulu lama-microcracks ku-matrix.
Ikakhulukazi sebenzisa ukuhlolwa kwangaphambili kwemvelo kanye nokulingisa imvelo ukuze ufunde umthelela wemiphumela yemvelo.Lokhu okubizwa ngokuthi ukwelapha kwangaphambili kwemvelo ukubeka into eyinhlanganisela ukuze ihlolwe endaweni ethile ukuze icutshungulwe kusenesikhathi, bese ubeka okokusebenza okucutshunguliwe ekuhlolweni komthelela wesivinini esiphansi kuzinga lokushisa elilingana negumbi.Ukuhlolwa kokulingisa kwemvelo ukubeka izinto eziyinhlanganisela egumbini lezemvelo ngenkathi kunomthelela.Le ndlela isetshenziselwa ukutadisha ukusebenza komthelela kwezingxenye ezindaweni ezihlukene zesevisi.
3. Umthelela wezakhiwo ezibonakalayo ekusebenzeni komthelela wesivinini esiphansi
I-fiber isetshenziswa kabanzi njengokuqinisa ekukhiqizeni izinto eziyinhlanganisela.Ngesikhathi esifanayo, njengomthwali oyinhloko womthwalo, ukusebenza kwefayibha kunomthelela omkhulu ekuphikiseni komthelela okuphelele kwezinto eziyinhlanganisela.Imicu esetshenziswa embonini ye-aerospace ikakhulukazi ihlanganisai-carbon fiber, ingilazi fiberkanye ne-Kevlar fiber.Ngenxa yokuqina okuyingqayizivele kwe-carbon fiber, ukumelana komthelela kwezinhlanganisela ze-resin matrix ye-carbon fibre kubuthakathaka kune-glass fiber ne-Kevlar fiber.
I-matrix ye-fiber-reinforced resin-based composite materials idlala indima ebaluleke kakhulu ezintweni eziyinhlanganisela.I-resin matrix ayihlukaniseki kusukela ekutheni idlulise umthwalo, igcine umumo wemicu noma igcine ubuqotho bento.Imiphumela yocwaningo ibonisa ukuthi nakuba izici zemishini ye-thermosetting resins zingcono kunezo ze-thermoplastic resins, isakhiwo se-molecular esixhunywe ngokuphambana se-thermosetting resins siwenza angabi namandla, okuwenza athambekele kakhulu ekuhlulekeni ngaphansi komthwalo womthelela.
Isixhumi esibonakalayo sidlala indima yokudlulisa umthwalo ku-fiber ezintweni eziyinhlanganisela, ngakho-ke ukusebenza kwesixhumi esibonakalayo kuzothinta ukusebenza okuphelele kwezinto eziyinhlanganisela.Impahla eyinhlanganisela enokusebenzelana okungalungile kokuhlangana phakathi kwefayibha kanye ne-matrix kuzobonisa amandla aphansi nokuqina, futhi ukubopha okuqine kakhulu kuzokwenza into ibe brittle.
I-Hebei Yuniu Fiberglass Manufacturing Company Limitedkuyintoumkhiqizi wezinto ezibonakalayo ze-fiberglass onolwazi olungaphezu kweminyaka eyi-10, isipiliyoni sokuthekelisa seminyaka engu-7.
Singabakhiqizi bezinto zokusetshenziswa ze-fiberglass, njenge i-fiberglass roving, intambo ye-fiberglass, i-fiberglass eqoshiwe ye-strand mat, izintambo eziqoshiwe ze-fiberglass, i-fiberglass black mat, i-fiberglass woven roving, indwangu ye-fiberglass, indwangu ye-fiberglass..Njalo njalo.
Uma kukhona izidingo, sicela usithinte ngokukhululekile.
Sizokwenza konke okusemandleni ethu ukukusiza futhi sikusekele.
