ʻO nā fibers hana kiʻekiʻe ʻekolu i ka honua i kēia mau lā: ʻo ka fiber aramid, ka fiber carbon, a me ka ultra-high molecular weight polyethylene fiber, a me ka ultra-high molecular weight polyethylene fiber (UHMWPE) nā hiʻohiʻona o ka ikaika kikoʻī kiʻekiʻe a me ka modulus kikoʻī. Ua hoʻohana nui ʻia nā huahana composite hana (nā mea haʻuki, nā kaula, a me nā mea ʻē aʻe) i nā ʻoihana like ʻole. I kēia manawa, ua holomua nui ka ʻenehana fiber molecular kiʻekiʻe o Kina i nā makahiki i hala iho nei. ʻO ka hoʻoikaika ʻana i ka fiber glass ka mea nui, a i nā makahiki i hala iho nei, ua hoʻolaha ʻia i kekahi ʻano ma muli o nā waiwai piha o ka aramid fiber. Eia nō naʻe, ma muli o nā kumu like ʻole e like me ke kumukūʻai, ʻo ka mākeke o ka aramid fiber (KEVLAR) i hoʻoikaika ʻia i ka uwea optical i hoʻoikaika ʻia i loko o ka emi ʻana, a ʻoi aku ka nui o nā mea hana a me nā mea hoʻohana e kālele ana i ka UHMWPE fiber, no ka mea, ʻo ka ultra-high molecular weight polyethylene fiber reinforced core he haʻahaʻa kumukūʻai a ʻoi aku ka maikaʻi o ka hana. Eia nō naʻe, ma muli o nā ʻano ʻano like ʻole o ka fiber (me ka pale ʻana i ka mahana, a me nā mea ʻē aʻe), ua kau ʻia nā koi kiʻekiʻe ma luna o ka processability a me ka wettability o ka resin. Ua hoʻohana maikaʻi ka hui i ka resin vinyl i ka resin i mālama ʻole ʻia i nā makahiki he nui aku nei. Ma ke kumu o ka ili aramid fiber pultrusion kaʻina, vinyl resin kūpono no ka ultra-kiʻekiʻe molecular kaumaha fiber pultrusion ua hoʻolauna ʻia, a ua hoʻohana ʻia i nā batches.The kumu kūʻai o kēia reinforcing core he 40% haʻahaʻa ma mua o ka aramid fiber, akā He kiʻekiʻe flexural a me nā waiwai tensile.
