xov xwm

Peb qhov kev ua tau zoo fiber ntau hauv ntiaj teb niaj hnub no yog: aramid fiber, carbon fiber, thiab ultra-high molecular hnyav polyethylene fiber, thiab ultra-high molecular hnyav polyethylene fiber (UHMWPE) muaj cov yam ntxwv ntawm lub zog tshwj xeeb thiab cov qauv tshwj xeeb.Cov khoom sib xyaw ua haujlwm (cov khoom siv ua kis las, hlua, thiab lwm yam) tau siv dav hauv ntau yam lag luam.Tam sim no, Tuam Tshoj lub ultra-siab molecular hnyav fiber ntau tshuab kuj ua tau zoo nyob rau hauv xyoo tas los no.Cov iav fiber reinforcement yog cov khoom tseem ceeb, thiab nyob rau hauv ob peb xyoos dhau los, nws tau nce mus rau ib qho twg vim muaj cov khoom ntawm aramid fiber ntau.Txawm li cas los xij, vim muaj ntau yam xws li tus nqi, kev ua lag luam ntawm aramid fiber ntau (KEVLAR) cov khoom siv kho qhov muag kho qhov muag muaj zog yog nyob rau hauv qhov maj mam shrinking, thiab ntau lub tuam txhab thiab cov neeg siv yuav tsom mus rau UHMWPE fiber ntau, vim tias ultra-siab molecular hnyav polyethylene fiber reinforced. core muaj tus nqi nruab nrab thiab kev ua haujlwm zoo dua.Txawm li cas los xij, vim muaj ntau tus yam ntxwv ntawm cov fiber ntau (xws li qhov kub thiab txias, thiab lwm yam), cov kev xav tau siab dua tau muab tso rau ntawm cov txheej txheem thiab kev ntub dej ntawm cov resin.Lub tuam txhab tau ua tiav siv cov yas yas rau cov khoom siv tsis tau kho ntau xyoo dhau los.Raws li cov txheej txheem saum npoo aramid fiber ntau pultrusion, vinyl resin haum rau ultra-high molecular hnyav fiber ntau pultrusion kuj tau qhia, thiab tau siv rau hauv cov khoom siv.Tus nqi ntawm cov tub ntxhais reinforcing no yog 40% qis dua li ntawm aramid fiber, tab sis muaj ntau dua flexural thiab tensile zog.
