Izindaba

Izakhiwo zesamishi ngokuvamile ziyinhlanganisela eyenziwe ngezingqimba ezintathu zezinto.Izendlalelo ezingenhla nezingezansi ze-sandwich composite material zinamandla aphezulu kanye ne-high-modulus materials, kanti ungqimba oluphakathi luyimpahla engasindi kakhulu.Isakhiwo sesemishi le-FRP empeleni siyinhlanganisela yezinto eziyinhlanganisela nezinye izinto ezingasindi.Isakhiwo sesangweji sisetshenziselwa ukuthuthukisa ukusetshenziswa okusebenzayo kwezinto kanye nokunciphisa isisindo sesakhiwo.Ukuthatha izingxenye ze-beam-slab njengesibonelo, ngesikhathi sokusetshenziswa, kuyadingeka ukuhlangabezana nezidingo zamandla nokuqina.Izici zamapulasitiki aqiniswe nge-fiber fiber zingamandla aphezulu, i-Modulus iphansi.Ngakho-ke, lapho ingilazi eyodwa yengilazi eqinisiwe impahla yepulasitiki isetshenziselwa ukwenza imishayo nama-slabs ukuhlangabezana nezidingo zamandla, ukuchezuka kuvame ukuba kukhulu kakhulu.Uma umklamo usekelwe ekuphambukeni okuvumelekile, amandla azokweqa kakhulu, okuholela ekulahlekeni.Kuphela ngokwamukela ukwakheka kwesakhiwo sesangweji lapho kungaxazululwa khona lokhu kuphikisana.Lesi futhi isizathu esiyinhloko sokuthuthukiswa kwesakhiwo samasemishi.

Ngenxa yamandla aphezulu, isisindo esilula, ukuqina okuphezulu, ukumelana nokugqwala, ukufakwa kukagesi kanye nokudluliswa kwe-microwave kwesakhiwo sesemishi le-FRP, sekusetshenziswe kabanzi ezindizeni, ezijikijelwayo, emikhathini namamodeli, amaphaneli ophahleni embonini yezindiza kanye nemboni ye-aerospace.Yehlisa isisindo sesakhiwo futhi uthuthukise umsebenzi wokusetshenziswa.Iphaneli yesangweji yengilazi esobala eqinisiwe isetshenziswe kabanzi ophahleni lokukhanyisa lwezitshalo zezimboni, izakhiwo ezinkulu zomphakathi kanye nezindawo zokugcina izithombo ezindaweni ezibandayo.Emkhakheni wokwakha umkhumbi nezokuthutha, izakhiwo zesemishi ze-FRP zisetshenziswa kabanzi ezingxenyeni eziningi kumikhumbi-ngwenya ye-FRP, abavukuzi basezimayini, kanye nezikebhe.Amabhuloho ezinyawo ze-FRP, amabhuloho emigwaqo emikhulu, izimoto nezitimela, njll. aklanywe futhi akhiqizwa ezweni lami konke amukela isakhiwo sesemishi le-FRP, esihlangabezana nezidingo zokusebenza eziningi zesisindo sokukhanya, amandla aphezulu, ukuqina okuphezulu, ukwahlukanisa ukushisa nokugcina ukushisa.Esembozweni sombani esidinga ukudluliswa kwe-microwave, isakhiwo sesangweji se-FRP sesiphenduke into ekhethekile ezinye izinto ezingenakuqhathaniswa nazo.

Izinhlobo nezici ze-FRP sandwich izakhiwo

Ngokwezinhlobo ezahlukene kanye nezinhlobo zezinto eziyinhloko ezisetshenziswa esakhiweni sesangweji, isakhiwo sesangweji se-FRP sihlukaniswe: isakhiwo sesemishi le-foam, isakhiwo sesemishi lezinyosi, isakhiwo sesemishi lepuleti le-trapezoidal, isakhiwo sesemishi elingunxande kanye nesakhiwo sesemishi esiyindilinga.

(1) Isakhiwo sesemishi yepulasitiki eyigwebu Isakhiwo sesemishi yepulasitiki eyigwebu sisebenzisa ishidi lepulasitiki eliqiniswe ngengilazi njengesikhumba (iphaneli) kanye negwebu njengongqimba oluyisisekelo.Izingxenye ezinamandla amancane nezimfuneko zokusebenza eziphezulu zokushisa, njengemisila yendiza, imigudu yokungenisa umoya eshisayo nezifanekiso.

(2) Isakhiwo sesemishi yekhekhe lezinyosi Isakhiwo sesemishi yekhekhe lezinyosi sisebenzisa ingilazi yepulasitiki eqiniswe ngefayibha yepulasitiki njengesikhumba, kanye nezinto zekhekheba lezinyosi (indwangu yengilazi yekhekhe lezinyosi, ikhekheba lezinyosi lephepha noma enye indwangu kakotini nekhekheba lezinyosi ze-aluminium, njll.) njengongqimba oluyisisekelo.Isakhiwo sesemishi lezinyosi sinesisindo esilula, sinamandla amakhulu futhi siqinile, futhi sisetshenziselwa kakhulu izingxenye zesakhiwo ezinobukhulu obukhulu besakhiwo kanye nezidingo zamandla aphezulu, njengamapuleti athwala imithwalo amabhuloho e-FRP, izakhiwo zophahla oluyindilinga, ama-radomes, ukukhanya. izindawo ezingaphezulu, izitezi zamaloli eziqandisiwe kanye nezakhiwo zamabhokisi Linda.

(3) Isakhiwo sesendlalelo se-trapezoidal kanye ne-rectangular lead-action layer Iphaneli (isikhumba) yalesi sakhiwo sesendlalelo se-lead-action siyishidi lepulasitiki eliqiniswe nge-fiber yengilazi, futhi ungqimba lwesemishi luyi-glass fiber eqiniswe ngeplasitiki ye-trapezoidal noma ipuleti elingunxande.Lesi sakhiwo sesemishi sinokuqondiswa okuqinile futhi silungele kuphela amapuleti ayisicaba aphezulu, hhayi emikhiqizweni enezimo ezigobile.

(4) Isakhiwo sesemishi emise okwendandatho Isebenzisa ingilazi yepulasitiki eqiniswe ngefayibha njengesikhumba kanye nendandatho yepulasitiki eqiniswe ngomucu wengilazi njengongqimba oluyisisekelo.Izici zalesi sakhiwo sesemishi ukuthi ukusetshenziswa kwezinto eziyinhloko kuphansi, amandla aphakeme kakhulu, futhi amandla epuleti awanakho ukuqondiswa.Yipuleti lesakhiwo sesangweji lepulasitiki elifanele kakhulu elibonakala lingenasici ukuze likhanyise.
