Peb lub fibers loj tshaj plaws hauv ntiaj teb niaj hnub no yog: aramid, carbon fiber, ultra-high molecular weight polyethylene fiber, thiab ultra-high molecular weight polyethylene fiber (UHMWPE) vim nws lub zog tshwj xeeb thiab modulus tshwj xeeb, siv rau hauv tub rog, aerospace, cov khoom siv ua ke siab (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 tsim los ntawm leaps thiab ciam teb. Tam sim no, hauv kev lag luam kev sib txuas lus, cov khoom tseem ceeb yog iav fiber reinforced. Nyob rau ob peb xyoos dhau los, nws kuj tau txhawb nqa vim yog kev ua tau zoo ntawm aramid fiber. Txawm li cas los xij, vim muaj ntau yam xws li tus nqi, kev ua lag luam rau aramid fiber (KEVLAR) reinforced fiber optic cable reinforced core maj mam poob qis, thiab ntau tus neeg tsim khoom thiab cov neeg siv tsom mus rau UHMWPE fiber, vim UHMWPE 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 rau kev ua tiav thiab kev ntub dej ntawm cov resin tau muab tso rau pem hauv ntej. Peb lub tuam txhab tau loj hlob thiab ua tiav siv cov vinyl resins rau cov txheej txheem kho aramid fiber pultrusion, ntawm lub hauv paus no, tau qhia cov vinyl resin uas haum rau ultra-high molecular weight fiber pultrusion, thiab tau siv ua pawg. Hom kev txhawb nqa no yog 40% qis dua tus nqi ntawm aramid fiber, tab sis Muaj cov khoom flexural thiab tensile siab dua.
