ʻO ka hoʻohele ʻana o ke olonā basalt, i hana ʻia mai ka ʻōpae basalt kūlohelohe ma o ka hoʻoheheʻe ʻana a me ke kaha kiʻi ʻana i ka mahana kiʻekiʻe, he ʻano hou ia o ka mea olonā inorganic aloha kaiapuni. Loaʻa iā ia nā ʻano maikaʻi loa o ka basalt, a me kāna hana maikaʻi loa, hōʻike ia i ka hiki ke hoʻohana nui ʻia ma nā ʻano he nui.

ʻO ka basalt fiber direct roving kahi puʻupuʻu i hoʻokumu ʻia ma ka hoʻohui ʻana i nā kaula like ʻole a i ʻole nā ​​​​kaula like hoʻokahi i kahi mokuʻāina untwisted. ʻAʻole wale ka ikaika kiʻekiʻe o ka fiber basalt, ka modulus kiʻekiʻe, a me ke kūpaʻa hopena e like me nā fibers ʻenehana kiʻekiʻe e like me PPTA (poly (p-phenylenediamine) a me UHMWPE (ultra high molecular weight polyethylene), akā he kūpaʻa kiʻekiʻe hoʻi i ka mahana kiʻekiʻe a me ke kukui, ʻoi aku ka ikaika o ka hoʻopili ʻana me ka resin. No laila, hiki ke hoʻohana ʻia nā kikoʻī like ʻole o ka basalt untwisted roving no ka ulana ʻana, ka wili ʻana, a me ka ulana ʻana i nā ʻāpana composite prefabricated like ʻole.

ʻO ka basalt fiber roving kahi mea hana kiʻekiʻe i hana ʻia mai ka pōhaku basalt kūlohelohe. Hana ʻia ia ma ka hoʻoheheʻe ʻana i ka basalt ma nā mahana kiʻekiʻe a hoʻopuka iā ia i loko o nā olonā mau. ʻIke ʻia no kona mau waiwai mechanical, thermal, a me kemika maikaʻi loa, hoʻohana nui ʻia ka basalt fiber roving i nā ʻoihana like ʻole. Hāʻawi kēia mea i kahi ratio ikaika-a-kaumaha kiʻekiʻe, e hoʻolilo ana iā ia i māmā akā paʻa. He kūpaʻa ia i nā mahana koʻikoʻi, nā kemika, ka radiation UV, a me ka corrosion, e kūpono ana no nā ʻano koi. Eia kekahi, ʻaʻole alakaʻi ka basalt fiber roving a hāʻawi i ka damping haʻalulu maikaʻi. Hoʻokomo ʻia nā noi i nā mea kūkulu hale, nā ʻāpana kaʻa, ka ikehu makani, a me nā ʻoihana aerospace. Ma ke ʻano he mea eco-friendly i loaʻa mai kahi kumuwaiwai kūlohelohe a nui, ʻo ka basalt fiber roving kahi koho maikaʻi loa i nā mea kuʻuna e like me ke kila a i ʻole fiberglass.

ʻO ka ulana ʻana o ka fiber basalt he kaola hui, kahi e hoʻohui ai i ka protofilament parallel stranded me ka sub-thread parallel protofilament i ke kūlana ulana ʻole. ʻAʻole wale ka fiber basalt i ka ikaika kiʻekiʻe like, ka modulus kiʻekiʻe, a me ka hana kū'ē haʻalulu me ke fiber ʻenehana kiʻekiʻe o PPTA a me UHMWPE akā he maikaʻi hoʻi ka thermostability a me ke kū'ē māmā, ʻoiai ke hui pū ʻia me ka resin, a he ikaika hoʻopaʻa kiʻekiʻe. No laila, hiki ke hoʻohana ʻia ka basalt woven roving o nā ʻano kikoʻī no ka ulana ʻana, ka wili ʻana, a me ke ulana ʻana i nā ʻano huahana prefab composite.
