Ulusi watatu wapamwamba kwambiri padziko lonse lapansi masiku ano ndi: aramid, carbon fiber, ultra-high molecular weight polyethylene fiber, ndi ultra-high molecular weight polyethylene fiber (UHMWPE) chifukwa cha mphamvu zake zapadera komanso modulus yeniyeni, imagwiritsidwa ntchito munkhondo, ndege, zinthu zopangidwa ndi zinthu zosiyanasiyana (zipangizo zamasewera, zingwe, ndi zina zotero) zakhala zikugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Pakadali pano, ukadaulo wa ulusi wa molecular weight high ku China wapangidwanso mwachangu kwambiri. Pakadali pano, mumakampani olumikizirana, chinthu chachikulu chomwe chimagwiritsidwa ntchito kwambiri ndi ulusi wagalasi wolimbikitsidwa. M'zaka zingapo zapitazi, chakwezedwanso chifukwa cha magwiridwe antchito a ulusi wa aramid. Komabe, chifukwa cha zinthu zosiyanasiyana monga mtengo, msika wa aramid fiber (KEVLAR) reinforced fiber optic cable reinforced core ukuchepa pang'onopang'ono, ndipo opanga ndi ogwiritsa ntchito ambiri amayang'ana kwambiri ulusi wa UHMWPE, chifukwa UHMWPE fiber reinforced core ili ndi mtengo wocheperako komanso magwiridwe antchito abwino. Komabe, chifukwa cha mawonekedwe osiyanasiyana a ulusi (kuphatikiza kukana kutentha, ndi zina zotero), zofunikira zapamwamba za ulusi wokonzedwa bwino komanso wonyowa zaperekedwa patsogolo. Pogwiritsa ntchito njira yopangira pultrusion ya aramid pamwamba, Beihai yatulutsanso utomoni wa vinyl woyenera pultrusion ya utomoni wolemera kwambiri, ndipo wagwiritsidwa ntchito m'magulu. Mtundu uwu wa core wolimbikitsidwa uli ndi mtengo wotsika kuposa utomoni wa aramid 40%, koma uli ndi mphamvu zambiri zopindika komanso zomangika.
