Iintlobo kunye neempawu zeteknoloji yokuvelisa isakhiwo sesandwich kwinkqubo yokuvelisa i-FRP

Uphuhliso olusempilweni noluzinzileyo lwalo naliphi na ishishini yimeko eyimfuneko kuphuhliso oluzinzileyo lwekhonkco loshishino lonke. Uphuhliso olusempilweni noluhlala luhleli lwemathiriyeli yemveli edibeneyo (ifayibha yeglasiiplastiki eyomeleziweyo) ishishini kufuneka lisekelwe kuphuhliso olusempilweni noluhlala luhleli lwefiber yeglasi enyukayo kunye nemizi-mveliso yepolyester engaxutywanga. Umzi-mveliso we-glass fiber ugqibe ukudityaniswa kwemizi-mveliso, wenza imveliso yelizwe yaseTshayina ekhuphisanayo, ngelixa ishishini le-resin elingaxutywanga lisanda kuqalisa ukuhlengahlengiswa koshishino, kwaye utshintsho oluzayo ngokuqinisekileyo luya kuzisa inzuzo kwishishini lezinto ezidityanisiweyo zemveli. zinempembelelo enkulu.

Ulwakhiwo lwesandwich ludla ngokuba yimidibano eyenziwe ngamaleko amathathu wemathiriyeli. Iingqimba eziphezulu kunye nezantsi ze-sandwich composite material ziphezulu-amandla kunye ne-high-modulus materials, kunye nomgangatho ophakathi yinto enzima kakhulu. IIsakhiwo sesandwich ye-FRPngokwenene ludibaniso lwemathiriyeli edibeneyo kunye nezinye izinto ezikhaphukhaphu. Ukusetyenziswa kwesakhiwo sesandwich kukuphucula ukusetyenziswa okusebenzayo kwezinto kunye nokunciphisa ubunzima besakhiwo. Ukuthatha amacandelo e-beam-slab njengomzekelo, kwinkqubo yokusetyenziswa, kuyimfuneko ukuhlangabezana neemfuno zamandla kunye nokuqina. Iimpawu zezinto ze-FRP zinamandla amakhulu, i-Modulus iphantsi. Ke ngoko, xa ifayibha enye yeglasi eyomeleziweyo yeplastiki isetyenziselwa ukwenza imiqadi kunye ne-slabs ukuhlangabezana neemfuno zamandla, ukuphambuka kuhlala kukhulu. Ukuba uyilo lusekelwe ekuphambukeni okuvumelekileyo, amandla aya kugqithwa kakhulu, okubangela inkunkuma. Kuphela ngokwamkela uyilo lwesakhiwo sesandwich apho oku kuphikisana kungasonjululwa ngokufanelekileyo. Esi sesona sizathu siphambili sophuhliso lwesakhiwo sesandwich.

Ngenxa yamandla aphezulu, ubunzima obukhanyayo, ukuqina okuphezulu, ukumelana nokugqwala, ukugqunywa kombane kunye nokuhanjiswa kwe-microwave yesakhiwo sesandwich ye-FRP, isetyenziswe ngokubanzi kwiinqwelomoya, imijukujelwa, i-spacecraft kunye nemodeli, iipaneli zephahla kwishishini le-aviation kunye ne-aerospace industry. Ukunciphisa ubunzima besakhiwo kunye nokuphucula umsebenzi wokusetyenziswa. Eselubalaifayibha yeglasiIphaneli yesandwich yeplastiki eqinisiweyo isetyenziswe ngokubanzi ekukhanyeni kwezityalo zezityalo, izakhiwo zoluntu ezinkulu kunye neendawo zokugcina izityalo kwiindawo ezibandayo. Kwintsimi yokwakhiwa kweenqanawa kunye nokuthutha, izakhiwo ze-sandwich ze-FRP zisetyenziswa ngokubanzi kumacandelo amaninzi kwi-submarines ye-FRP, i-minesweepers, kunye ne-yachts. Iibhulorho zabahambi ngeenyawo ze-FRP, iibhulorho zendlela, iimoto kunye noololiwe, njl.njl. ezenzelwe kwaye zenziwe kwilizwe lam zonke zamkela isakhiwo sesandwich ye-FRP, ehlangabezana neemfuno zokusebenza ezininzi zobunzima bokukhanya, amandla aphezulu, ukuqina okuphezulu, ukufudumala ukushisa kunye nokugcinwa kobushushu. Kwisigqubuthelo sombane esifuna ukuhanjiswa kwe-microwave, isakhiwo se-sandwich ye-FRP siye saba yinto ekhethekileyo kwezinye izinto ezingenakuqhathaniswa nazo.
