ʻO ka Fiberglass roving kahi kaula mau o nā olonā aniani e hāʻawi ana i ka ikaika kūikawā a me ka versatility i ka hana composite. Hoʻohana nui ʻia ia i nā noi like ʻole ma muli o kona ikaika tensile kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ke kūpaʻa kemika maikaʻi loa. ʻO kekahi o nā noi koʻikoʻi o ka fiberglass roving ʻo ia ka hana ʻana o ka Sheet Molding Compound (SMC). I ke kaʻina hana SMC, ua hānai ʻia ka fiberglass roving i loko o kahi mea ʻoki rotary, kahi e ʻoki ʻia ai i nā lōʻihi pōkole (maʻamau 25mm a i ʻole 50mm) a waiho ʻia ma luna o kahi paʻi resin. A laila hoʻopaʻa ʻia kēia hui pū ʻana o ka resin a me ka roving i ʻoki ʻia i loko o kahi ʻano pepa, e hana ana i kahi mea kūpono loa no ka hoʻoheheʻe ʻana i ka compression.
Ma waho aʻe o SMC, hoʻohana ʻia ka roving fiberglass i nā kaʻina hana pīpī. Maanei, hoʻokomo ʻia ka roving ma o kahi pū pīpī, kahi e ʻoki ʻia ai a hui pū ʻia me ka resin ma mua o ka pīpī ʻia ʻana ma luna o kahi ʻōmole. He kūpono loa kēia ʻano hana no ka hana ʻana i nā ʻano paʻakikī a me nā hale nui, e like me nā ʻili waʻa a me nā ʻāpana kaʻa. ʻO ke ʻano hoʻomau o ka roving e hōʻoiaʻiʻo ana he ikaika mechanical kiʻekiʻe a me ka lōʻihi ka huahana hope loa.
He kūpono hoʻi ka fiberglass roving no nā noi hoʻopaʻa lima, kahi e hiki ai ke ulana ʻia i loko o nā lole a hoʻohana ʻia paha e like me ka hoʻoikaika ʻana i nā laminates mānoanoa. ʻO kona hiki ke omo koke i ka resin (wet-out) e kūpono ia no nā kaʻina hana lima, kahi e koʻikoʻi ai ka wikiwiki a me ka maʻalahi o ka lawelawe ʻana. Ma keʻano holoʻokoʻa, he mea maʻalahi ka fiberglass roving e hāʻawi ana i ka ikaika a me ka hana maikaʻi loa ma nā ʻano hana hana composite like ʻole.
