Peb lub fibers loj tshaj plaws hauv ntiaj teb niaj hnub no yog: aramid fiber, carbon fiber, thiab ultra-high molecular weight polyethylene fiber, thiab ultra-high molecular weight polyethylene fiber (UHMWPE) muaj cov yam ntxwv ntawm lub zog tshwj xeeb thiab modulus tshwj xeeb. Cov khoom sib xyaw ua ke (cov khoom siv kis las, hlua, thiab lwm yam) tau siv dav hauv ntau yam lag luam. Tam sim no, Tuam Tshoj txoj kev siv tshuab ultra-high molecular weight fiber kuj tau ua tiav zoo hauv xyoo tas los no. Cov iav fiber reinforcement yog cov khoom tseem ceeb, thiab ob peb xyoos dhau los, nws tau txhawb nqa mus rau qee qhov vim yog cov khoom siv dav dav ntawm aramid fiber. Txawm li cas los xij, vim muaj ntau yam xws li tus nqi, kev ua lag luam ntawm aramid fiber (KEVLAR) reinforced optical cable reinforced core yog maj mam poob qis, thiab ntau tus neeg tsim khoom thiab cov neeg siv yuav tsom mus rau UHMWPE fiber, vim tias ultra-high molecular weight polyethylene fiber reinforced core muaj tus nqi nruab nrab thiab kev ua tau zoo dua. Txawm li cas los xij, vim muaj ntau yam ntxwv ntawm cov fiber (xws li kev tiv taus kub, thiab lwm yam), cov kev xav tau siab dua tau muab tso rau ntawm kev ua tiav thiab kev ntub dej ntawm cov resin. Lub tuam txhab tau ua tiav siv cov vinyl resin rau cov resin tsis tau kho ntau xyoo dhau los. Raws li cov txheej txheem pultrusion ntawm aramid fiber saum npoo av, cov vinyl resin uas tsim nyog rau ultra-high molecular weight fiber pultrusion kuj tau qhia, thiab tau siv ua pawg. Tus nqi ntawm cov tub ntxhais reinforcing no qis dua 40% piv rau aramid fiber, tab sis muaj cov yam ntxwv flexural thiab tensile siab dua.
