Nā laina pultruded FRP a me nā ʻike hana ʻoihana

Aia nā ʻano hui like ʻole ma laila ke pili i nā kaʻa a me nā ʻano o ka halihali.ʻO FRP, RTM, SMC, a me LFI kekahi o nā mea kaulana loa.Loaʻa i kēlā me kēia me kāna mau pono kūʻokoʻa ponoʻī, e pili ana a kūpono i nā pono a me nā kūlana ʻoihana o kēia lā.Aia ma lalo iho kahi nānā wikiwiki i kēia mau composites a me nā mea a kēlā me kēia o lākou e hāʻawi ai.

Pākīpika i hoʻopaʻa ʻia i ka fiber (FRP)

ʻO FRP kahi mea i hui pū ʻia me kahi matrix polymer i hoʻoikaika ʻia e nā fiber.Hiki i kēia mau fiber ke komo i kekahi mau mea me ka aramid, aniani, basalt, a i ʻole carbon.ʻO ka polymer ka mea maʻamau he plastic thermosetting i loaʻa i ka polyurethane, vinyl ester, polyester, a i ʻole epoxy.

Nui nā pōmaikaʻi o FRP.Ke kūʻē nei kēia ʻano hui i ka corrosion no ka mea ʻaʻohe wai a me ka porous.Loaʻa i ka FRP ka ikaika i ka ratio paona i ʻoi aku ka kiʻekiʻe ma mua o nā metala, thermoplastics, a me ke koneki.Hāʻawi ia i ka hoʻomanawanui hoʻokahi ʻili no ka mea hiki ke hana ʻia me ka hoʻohana ʻana i ka hapalua mold.Hiki ke hoʻohana i ka uila me nā mea hoʻopiha piha, mālama maikaʻi i ka wela nui, a hiki i nā hoʻopau makemake he nui.

Hoʻoheheʻe Resin (RTM)

ʻO RTM kekahi ʻano o ka hoʻoheheʻe wai hui.Hoʻohui ʻia kahi catalyst a paʻakikī paha me kahi resin a laila hoʻokomo ʻia i loko o kahi mole.Aia i loko o kēia poni ka fiberglass a i ʻole nā ​​mea maloʻo ʻē aʻe e kōkua i ka hoʻoikaika ʻana i ka composite.

Hāʻawi ka RTM composite i nā ʻano paʻakikī a me nā ʻano e like me nā pihi hui.He māmā a paʻa loa, me ka hoʻouka ʻana o ka fiber mai 25-50%.o ka RTM aia i loko o ka fiber content.Hoʻohālikelike ʻia me nā mea hoʻohui ʻē aʻe, ʻoi aku ka maʻalahi o ka RTM e hana.Hāʻawi kēia hoʻoheheʻe ʻana i nā ʻaoʻao i hoʻopau ʻia ma waho a me loko me ka hiki ke kala.

Hui Hoʻohui Pepa (SMC)

ʻO SMC kahi polyester i hoʻopaʻa ʻia i hoʻomākaukau ʻia i loko o ka fiber aniani, akā hiki ke hoʻohana ʻia nā fibers ʻē aʻe.Loaʻa ka pepa no kēia composite i nā ʻōwili, a laila ʻoki ʻia i loko o nā ʻāpana liʻiliʻi i kapa ʻia ʻo "charges".Hoʻolaha ʻia nā kaula kalapona lōʻihi a i ʻole aniani ma luna o kahi ʻauʻau resin.ʻO ka resin maʻamau ka epoxy, vinyl ester a i ʻole polyester.

ʻO ka maikaʻi nui o SMC ʻo ia ka hoʻonui ʻana i ka ikaika ma muli o kona mau fiber lōʻihi, ke hoʻohālikelike ʻia me nā pūhui hoʻoheheʻe nui.He kū'ē i ka corrosion, hiki ke hana, a hoʻohana ʻia no nā pono ʻenehana like ʻole.Hoʻohana ʻia ʻo SMC i nā noi uila, a me ka ʻenehana a me nā ʻenehana transit ʻē aʻe.

ʻO ka hoʻoheheʻe ʻana i ka fiber lōʻihi (LFI)

He kaʻina hana ka LFI mai ka hui ʻana o ka polyurethane a me ka fiber ʻokiʻoki ʻia a hoʻoheheʻe ʻia i loko o kahi lua.Hiki ke pena ʻia kēia lua poʻi me ka hana ʻana i kahi ʻāpana i hoʻopau pono ʻia ma waho o ka poʻi.ʻOiai e hoʻohālikelike pinepine ʻia me SMC ma ke ʻano he ʻenehana kaʻina hana, ʻo nā pōmaikaʻi nui ʻo ia ka hāʻawi ʻana i kahi hopena ʻoi aku ka maikaʻi no nā ʻāpana i pena ʻia, me ka loaʻa ʻana o nā kumukūʻai haʻahaʻa haʻahaʻa ma muli o kona haʻahaʻa haʻahaʻa.Aia kekahi mau hana koʻikoʻi ʻē aʻe i ka hana ʻana i nā mea LFI e like me ka ana ʻana, ka ninini ʻana, ka pena, a me ka hoʻōla ʻana.

Hoʻonui ka LFI i ka ikaika ma muli o kāna mau ʻokiʻoki lōʻihi.Hiki ke hana ʻia kēia composite me ka pololei, maʻamau, a me ka wikiwiki e hoʻohālikelike ʻia me nā mea hui ʻē aʻe.ʻOi aku ka māmā o nā ʻāpana i hana ʻia me ka ʻenehana LFI a ʻoi aku ka maʻalahi o ka hoʻohālikelike ʻana i nā kaʻina hana kuʻuna.ʻOiai ua hoʻohana ʻia ʻo LFI no kekahi manawa i kēia manawa i nā kaʻa a me nā mea hana transit ʻē aʻe, ke hoʻomaka nei e loaʻa ka mahalo nui ʻia i ka mākeke kūkulu hale.

Ma ka hōʻuluʻulu

Loaʻa i kēlā me kēia o nā composites maʻamau i hōʻike ʻia ma ʻaneʻi.Ma muli o nā hopena hopena i makemake ʻia o kahi huahana, pono e noʻonoʻo pono kēlā me kēia mea e ʻike i ka mea e kūpono i nā pono o kahi hui.

E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou

Inā he mau nīnau kāu e pili ana i nā koho composite maʻamau a me nā pōmaikaʻi, makemake mākou e kamaʻilio me ʻoe.Ma Romeo RIM, ke hilinaʻi nei mākou e hiki iā mākou ke hāʻawi i ka hopena kūpono i kāu mau pono hana, E kelepona mai iā mākou i kēia lā no ka ʻike hou aku.
