ʻO ka uhi FRP kahi ʻano hana maʻamau a koʻikoʻi loa no ka kaohi ʻana i ka palaho i ke kūkulu ʻana i ka hana kaumaha anti-corrosion. I waena o lākou, hoʻohana nui ʻia ka FRP lay-up lima ma muli o kona hana maʻalahi, ka maʻalahi a me ka maʻalahi. Hiki ke ʻōlelo ʻia ʻo ke ʻano hana lay-up lima no ka ʻoi aku ma mua o 80% o ke kūkulu ʻana i ka FRP anti-corrosion. ka nui. ʻO nā "mea nui ʻekolu" resin, fiber a me ka pauka fiber i loko o ka FRP i waiho lima ʻia nā iwi o FRP, e kākoʻo ana i ka ikaika o ka ʻōnaehana FRP, a he ʻāpana koʻikoʻi ia o ka hoʻomaopopo ʻana i ka hopena lōʻihi o ka anti-corrosion o FRP.

Wahi a ka ʻokoʻa o ke kaiapuni ʻino a me ke kikowaena, e loli pū nā mea hana o ka FRP. ʻO ke koho ʻana i nā mea kūlana i ka wā o ke kūkulu ʻana he mea nui ia e hōʻoia i ka hiki i ka huahana FRP i hoʻopau ʻia ke hoʻololi i ke kaiapuni ʻino a me kona kūpaʻa. No laila, pono e hoʻoholo ʻia ke koho ʻana o nā mea hoʻoikaika FRP ma mua o ke kūkulu ʻana. No ka laʻana, ʻo nā mea hoʻoikaika i hōʻike ʻia e ka fiber aniani nā mea fiber maʻamau, hiki ke kū i ka hapa nui o ka corrosion acid; akā naʻe, ʻaʻole lākou e kū i ka hydrofluoric acid a me ka phosphoric acid corrosion wela. E hoʻohana i ka polyester, polypropylene a me nā lole fiber organik a me ka felt, hiki iā ʻoe ke koho e hoʻohana i ka linen a i ʻole ka gauze degreased, a pono kekahi mau huahana FRP i ke kūpaʻa a me ka conductivity, hiki iā ʻoe ke koho i nā mea fiber carbon. I kahi huaʻōlelo, ʻo ke koho ʻana i ka fiber i hoʻoikaika ʻia me ka FRP he mākaukau a me ka ʻike e pono ai i ka ʻenehana anti-corrosion a me nā mea hoʻolālā ke aʻo.

I loko o nā huahana FRP i hoʻopili ʻia, ʻo ka hapa nui o nā olonā hoʻoikaika he olonā aniani, inā he lole, he huluhulu paha, a he olonā paha. ʻO ke kumu nui, ma waho aʻe o ke kumu kūʻai, loaʻa iā ia nā ʻano maikaʻi loa:
01 Ke kū'ē kemika
ʻAʻole e pala, ʻōpala a pala paha nā olonā lole fiberglass inorganic. He kūpaʻa lākou i ka hapa nui o nā waikawa koe wale nō ka hydrofluoric a me ka waikawa phosphoric wela.
02 Paʻa ka nui
ʻAʻole e kīkoʻo a emi paha nā olonā aniani i hoʻohana ʻia no ka hana ʻana i nā lole aniani ma muli o nā loli o nā kūlana lewa. ʻO ka elongation maʻamau i ka haki ʻana he 3-4%. ʻO ka awelika linear thermal expansion coefficient o ka bulk E-glass he 5.4 × 10-6 cm/cm/°C.
03 Hana wela maikaʻi
ʻOi aku ka haʻahaʻa o ka coefficient o ka hoʻonui wela o nā lole Fiberglass a ʻoi aku ka kiʻekiʻe o ka conductivity thermal. Hoʻopau wikiwiki ka Fiberglass i ka wela ma mua o ka asbestos a i ʻole nā ​​​​​​lohi organik.
04 Ikaika tensile kiʻekiʻe
He kiʻekiʻe ka lakio o ka ikaika a me ke kaumaha o ka olonā fiberglass. ʻOi aku ka ikaika o ka paona o ka olonā fiberglass ma mua o ka uea kila. ʻO ka hiki ke hana i ka ikaika hoʻokahi a i ʻole bidirectional i loko o ka lole e hoʻonui nui i ka maʻalahi o nā huahana hoʻohana hope.
05 Ke kūpaʻa wela kiʻekiʻe
ʻAʻole wela nā olonā aniani inorganic a palekana loa i nā mahana hoʻomoʻa a hoʻōla kiʻekiʻe i loaʻa pinepine ʻia i ka hana ʻoihana. E mālama ka Fiberglass ma kahi o 50% o kona ikaika ma 700°F a me 25% ma 1000°F.
06 Hygroscopicity haʻahaʻa
Hana ʻia nā olonā fiberglass me nā olonā non-porous a no laila he haʻahaʻa loa ka omo ʻana o ka makū.
07 Palekana uila maikaʻi
ʻO ka ikaika dielectric kiʻekiʻe a me ka dielectric constant haʻahaʻa, me ka haʻahaʻa o ka omo wai a me ke kūpaʻa wela kiʻekiʻe, e hana i nā lole fiberglass i mea maikaʻi loa no ka insulation uila.
08 Ka maʻalahi o ka huahana
ʻO nā filaments maikaʻi loa i hoʻohana ʻia i nā olonā fiberglass, nā ʻano nui a me nā hoʻonohonoho olonā like ʻole, nā ʻano ulana like ʻole, a me nā hoʻopau kūikawā he nui e hoʻolilo i nā lole fiberglass i mea pono no nā ʻano hoʻohana ʻoihana like ʻole.
09 kumukūʻai haʻahaʻa kumukūʻai haʻahaʻa
Hiki i nā lole Fiberglass ke hana i ka hana a ua like ke kumukūʻai me nā lole fiber synthetic a me nā lole fiber kūlohelohe.

No laila, ʻo ka fiber aniani kahi mea hoʻoikaika lima FRP kūpono loa, he mea hoʻokele waiwai, ʻaʻole pipiʻi, a maʻalahi hoʻi e hana. ʻO ia kekahi o nā mea i hoʻohana nui ʻia ma waena o nā mea hoʻoikaika he nui i kēia manawa.
