Histori ea thepa e entsoeng ka polasetiki
Ha lisebelisoa tse peli kapa ho feta tse fapaneng li kopantsoe, phello e ba thepa e nang le motsoako.Tšebeliso ea pele ea thepa e kopantsoeng e qalile ka 1500 BC, ha Baegepeta ba pele le bajaki ba Mesopotamia ba ne ba kopanya seretse le joang ho theha mehaho e matla le e tšoarellang.Litlhaka li ntse li tsoela pele ho fana ka matlafatso bakeng sa lihlahisoa tsa khale tsa motsoako ho kenyelletsa le lipitsa tsa letsopa le likepe.
Hamorao, ka 1200 AD, Mamongolia a ile a qapa seqha sa pele sa motsoako.
Ho sebelisa motsoako oa lehong, masapo le "sekhomaretsi sa liphoofolo", seqha se phuthetsoe ka makhapetla a birch.Liqha tsena li matla ebile li nepahetse.Seqha se kopaneng sa Mongolia se thusitse ho netefatsa puso ea sesole ea Genghis Khan.
Tsoalo ea "Plastic Era"
Ha bo-rasaense ba etsa lipolasetiki, mehla ea kajeno ea lisebelisoa tse entsoeng ka metsoako e ile ea qala.Pele ho mona, lirekere tsa tlhaho tse nkiloeng limela le liphoofolo e ne e le tsona feela mohloli oa likhomaretsi le likhomaretsi.Mathoasong a lekholo la bo20 la lilemo, ho ile ha etsoa lipolasetiki tse kang vinyl, polystyrene, phenolic le polyester.Lisebelisoa tsena tse ncha tsa maiketsetso li phahametse li-resin tse le 'ngoe tse nkiloeng tlhahong.
Leha ho le joalo, polasetiki feela e ke ke ea fana ka matla a lekaneng bakeng sa lisebelisoa tse ling tsa meralo.Matlafatso ea hlokahala ho fana ka matla a eketsehileng le ho tiea.
Ka 1935, Owens Corning (Owens Corning) o ile a hlahisa fiber ea pele ea khalase, fiber ea khalase.Motsoako oa fiber ea khalase le polymer ea polasetiki e hlahisa mohaho o matla haholo oo hape o leng bobebe.
Ena ke qalo ea indasteri ea fiber reinforced polymer (FRP).
Ntoa ea II ea Lefatše-Ho khothaletsa boqapi ka thepa e kopaneng
Bongata ba tsoelo-pele e kholo ka ho fetisisa ea thepa e kopantsoeng ke liphello tsa litlhoko tsa nako ea ntoa.Feela joalokaha Mamongolia a ile a hlahisa liqha tse kopantsoeng, Ntoa ea II ea Lefatše e ile ea tlisa indasteri ea FRP ho tloha laboratoring ho ea ho tlhahiso ea sebele.
Lisebelisoa tse bobebe tsa lifofane tsa sesole li hloka lisebelisoa tse ling.Baenjiniere ba ile ba lemoha ka potlako melemo e meng ea lisebelisoa tse kopantsoeng, ho phaella ho bobebe le bo matla.Ka mohlala, ho ile ha fumanoa hore thepa e entsoeng ka khalase ea fiber e ne e le pepeneneng ho maqhubu a seea-le-moea, 'me thepa e ne e se e loketse ho sireletsa thepa ea radar ea elektronike (Radomes).
Ho ikamahanya le lisebelisoa tse kopantsoeng: "nako ea sebaka" ho "letsatsi le leng le le leng"
Qetellong ea Ntoa ea Bobeli ea Lefatše, indasteri e nyenyane ea li-composites e ne e ntse e tsoela pele.Ka ho fokotseha ha tlhokahalo ea lihlahisoa tsa sesole, palo e nyenyane ea baetsi ba lisebelisoa tse entsoeng ka metsoako e se e sebetsa ho hlahisa thepa e kopantsoeng limmarakeng tse ling.Sekepe ke sehlahisoa se totobetseng se ruisang molemo.Mohaho oa pele oa khoebo o kopantsoeng o ile oa qalisoa ka 1946.
Ka nako ena, Brandt Goldsworthy o atisa ho bitsoa "ntate-moholo oa li-composites" 'me o hlahisitse mekhoa e mengata e mecha ea tlhahiso le lihlahisoa, ho kenyeletsoa le letlapa la pele la fiberglass, le ileng la fetola lipapali.
Goldsworthy o ile a boela a qapa mokhoa oa ho etsa o bitsoang pultrusion, o lumellang lihlahisoa tse matlafalitsoeng le tse matla tsa khalase.Kajeno, lihlahisoa tse entsoeng ka mokhoa ona li kenyelletsa lipina tsa litepisi, lithupa tsa lisebelisoa, liphaephe, metsu, lihlomo, mekato ea terene le lisebelisoa tsa bongaka.
Khatelo-pele e tsoelang pele ea lisebelisoa tse kopantsoeng
Indasteri ea thepa e kopaneng e ile ea qala ho hola ka bo-1970.Theha li-resin tsa polasetiki tse betere le likhoele tse ntlafalitsoeng tse matlafatsang.Ho thehile mofuta oa fiber ea aramid e bitsoang Kevlar, e fetohileng khetho ea pele bakeng sa lihlomo tsa 'mele ka lebaka la matla a eona a holimo, boima bo phahameng le boima bo bobebe.Fiber ea carbon le eona e ile ea hlahisoa ka nako ena;e ntse e tsoela pele ho nkela likarolo tse entsoeng ka tšepe sebaka pele.
Indasteri ea li-composite e ntse e tsoela pele, 'me boholo ba kholo e itšetlehile haholo ka matla a ka nchafatsoang.Li-blade tsa turbine tsa moea, haholo-holo, li tsoela pele ho hatella litšitiso tsa boholo mme li hloka lisebelisoa tse tsoetseng pele tse kopaneng.
