ʻO ka mea hoʻoikaika i ka iwi kākoʻo o kahuahana FRP , ka mea e hoʻoholo ai i nā waiwai mechanical o ka huahana pultruded. ʻO ka hoʻohana ʻana i ka mea hoʻoikaika i kekahi hopena i ka hōʻemi ʻana i ka shrinkage o ka huahana a me ka hoʻonui ʻana i ka wela deformation wela a me ka ikaika haʻahaʻa haʻahaʻa haʻahaʻa.
I ka hoʻolālā ʻana o nā huahana FRP, pono e noʻonoʻo pono ke koho ʻana i nā mea hoʻoikaika i ke kaʻina hana o ka huahana, no ka mea, ʻo ke ʻano, ke ʻano o ka waiho ʻana a me nā ʻike o ka hoʻoikaika ʻana i nā mea he mana nui i ka hana o nā huahana FRP, a hoʻoholo lākou i ka mechanical. ikaika a me ka modulus elastic o nā huahana FRP. ʻOkoʻa ka hana o nā huahana pultruded me ka hoʻohana ʻana i nā mea hoʻoikaika ʻokoʻa.
Eia kekahi, ʻoiai e hālāwai ana i nā koi o ka hana huahana o ke kaʻina hana, pono e noʻonoʻo ʻia ke kumukūʻai, a koho ʻia nā mea hoʻoikaika haʻahaʻa e like me ka hiki. ʻO ka mea maʻamau, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka holo ʻole ʻana o nā kaula aniani ma mua o nā lole fiber; ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka lole, a maikaʻi ka impermeability. aka, ua emi ka ikaika; ʻoi aku ka liʻiliʻi o ka fiber alkali ma mua o ka fiber alkali-free, akā me ka piʻi ʻana o ka ʻike alkali, e emi ana kona kūpaʻa alkali, ke kūpaʻa corrosion a me nā waiwai uila.
ʻO nā ʻano o nā mea hoʻoikaika maʻamau e like me kēia:
1. Kaawili ana i ke aniani puluniu
Me ka hoʻohana ʻana i ka mea hoʻonui nui, hiki ke hoʻokaʻawale ʻia ke aniani fiber roving i ʻekolu mau ʻano: ka plied strand, the direct untwisted roving and the bulked untwisted roving.
Ma muli o ka ʻoluʻolu ʻole o nā kaula plied, ua maʻalahi ka sag, e hana i kahi loop loose ma ka hope hānai o nā mea pultrusion, e pili ana i ka holomua holomua o ka hana.
Loaʻa nā hiʻohiʻona o ka hui pū ʻana, ke komo ʻana i ka resin wikiwiki, a me nā waiwai mechanical maikaʻi loa o nā huahana, no laila ka hapa nui o lākou e hoʻohana i nā rovings pololei ʻole i kēia manawa.
He mea maikaʻi ka holo nui ʻana e hoʻomaikaʻi i ka ikaika transverse o nā huahana, e like me ka crimped roving a me ka ea-textured roving. Loaʻa i ka bulk roving ka ikaika kiʻekiʻe o nā fiber lōʻihi mau a me ka nui o nā fiber pōkole. He mea ia me ke kiʻekiʻe o ka wela, ka haʻahaʻa haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion, ka mana kiʻekiʻe a me ka pono kānana kiʻekiʻe. Hoʻopili ʻia kekahi mau fibers i kahi mokuʻāina monofilament, no laila hiki iā ia ke hoʻomaikaʻi i ka maikaʻi o ka ʻili o nā huahana pultruded. I kēia manawa, ua hoʻohana nui ʻia nā rovings bulked ma ka home a me nā ʻāina ʻē, ma ke ʻano he mau lole weft a me nā lole ulana no nā lole i ulana ʻia. Hiki ke hoʻohana ʻia e hana i ka friction, insulation, pale a i ʻole nā mea hoʻopaʻa.
ʻO nā koi hana o ka fiber aniani untwisted roving no ka pultrusion:
(1) ʻAʻohe hanana drape
(2) ʻAʻahu ʻaʻahu ʻokoʻa
(3) ʻO ka hui maikaʻi
(4) Kūleʻa lole maikaʻi
(5) Haʻihaʻi ka liʻiliʻi o nā poʻo, ʻaʻole maʻalahi ke hoʻoulu
(6) Maikaʻi wettability a me ka wikiwiki resin impregnation
(7) Ka ikaika kiʻekiʻe a me ka rigidity.
2. Moena aniani
I mea e lawa ai ka ikaika transverse o nā huahana FRP pultruded, pono e hoʻohana i nā mea hoʻoikaika e like me ka moena ʻoki ʻoki, ka moena kaula mau, ka moena hui, a me ka lole roving. ʻO ka moena strand mau ʻo ia kekahi o nā mea hoʻoikaika maʻamau o ke aniani fiber transverse i kēia manawa. I mea e hoʻomaikaʻi ai i ke ʻano o nā huahana, hoʻohana ʻia ka moena ili i kekahi manawa.
ʻO ka moena strand mau i haku ʻia me nā ʻāpana he nui o nā kīʻaha aniani mau i hoʻomoe wale ʻia i loko o ka pōʻai, a ua hoʻopaʻa ʻia nā kaula me kahi mea hoʻopili. ʻO ka moena ʻili he ʻiʻo like me ka pepa ʻiʻo i hana ʻia e ka waiho ʻana i nā kaula i ʻoki ʻia o ka lōʻihi paʻa a hoʻopaʻa ʻia me kahi mea hoʻopili. ʻO ka maʻiʻo fiber he 5% a 15%, a ʻo ka mānoanoa he 0.3 a 0.4 mm. Hiki iā ia ke hana i ka ʻili o ka huahana i maʻalahi a nani, a hoʻomaikaʻi i ke kūpaʻa ʻelemakule o ka huahana.
ʻO nā hiʻohiʻona o ka moena fiber aniani: ʻo ka uhi maikaʻi, maʻalahi ke hoʻopiha ʻia me ka resin, a me ka ʻike kiʻekiʻe.
ʻO nā koi o ke kaʻina hana pultrusion no ka moena fiber aniani:
(1) Loaʻa iā ia ka ikaika mechanical kiʻekiʻe
(2) No nā moena mānoanoa i kālai ʻia me ke kemika, pono ke kūpaʻa ka mea hoʻopaʻa i nā hopena kemika a me ka wela i ka wā o ka ʻū ʻana a me ka hana mua ʻana e hōʻoia i ka ikaika i ka wā o ke kaʻina hana.
(3) Hiki ke pulu maikaʻi
(4) Liʻiliʻi liʻiliʻi a liʻiliʻi ka haki ʻana i nā hui/hopena
3.PolyesterFiberSurfaceKiʻi
He ʻano hou o ka hoʻoikaika ʻana i ka fiber fiber ma ka ʻoihana pultrusion. Aia kekahi huahana i kapa ʻia ʻo Nexus ma ʻAmelika Hui Pū ʻIa, kahi i hoʻohana nui ʻia i nā huahana pultruded e pani ai i nā moena ili o ke aniani fiber/tissue/fleece. He hopena maikaʻi a me ke kumu kūʻai haʻahaʻa. Ua hoʻohana maikaʻi ʻia ma mua o 10 mau makahiki.
ʻO nā pōmaikaʻi o ka hoʻohana ʻana i ka polyester fiber surface tissue:
(1) Hiki iā ia ke hoʻomaikaʻi i ka pale ʻana i ka hopena, ka pale ʻana i ka corrosion a me ke kūpaʻa kahiko o ka lewa o ka huahana
(2) Hiki iā ia ke hoʻomaikaʻi i ke kūlana ʻili o ka huahana a hoʻomaʻamaʻa i ka ʻili o ka huahana
(3) ʻOi aku ka maikaʻi o ka ʻili o ka polyester fiber, ʻoi aku ka maikaʻi o ka hana pipili a me ka hana tensile ma mua o ka ʻili aniani C / moena, a ʻaʻole maʻalahi ka haki ʻana i nā hopena i ka wā o ka pultrusion, e hōʻemi ana i nā pōpilikia kaʻa.
(4) Hiki iā ia ke hoʻomaikaʻi i ka wikiwiki pultrusion
(5) Hiki iā ia ke ho'ēmi i kaʻaʻahu o ka'ōpala a hoʻonui i ke ola lawelawe.
4. anianiCloth/Tape
I kekahi mau huahana pultruded kūikawā, i mea e hoʻokō ai i kekahi mau koi hana kūikawā, hoʻohana ʻia ka lole aniani me ka laulā paʻa a me ka mānoanoa o lalo o 0.2mm, a maikaʻi loa kona ikaika tensile a me ka transverse ikaika.
5. Noi oUa ʻōlelo ʻo Twō-ʻanoFʻaʻahu& ʻekolu-nuiFʻaʻahu
ʻAʻole maikaʻi nā ʻano mīkini transverse o nā huahana composite pultruded. ʻO ka hoʻohana ʻana i ka braiding ʻelua ala e hoʻomaikaʻi maikaʻi i ka ikaika a me ka paʻakikī o nā huahana pultruded.
ʻAʻole i hui pū ʻia ke kaula a me ka weft o kēia lole i ulana ʻia, akā ua hui pū ʻia me nā mea ulana ʻē aʻe, no laila ʻokoʻa loa ia mai ka lole aniani kahiko. Aia nā fibers i kēlā me kēia ʻaoʻao i kahi kūlana collimated a ʻaʻole i hoʻokumu i kekahi kulou, a no laila ka ikaika a me ka ʻoʻoleʻa o ka huahana pultruded, ʻoi aku ka kiʻekiʻe ma mua o ka composite i hana ʻia me ka manaʻo mau. I kēia manawa, ua lilo ka ʻenehana ulana ʻekolu ala i mea hoʻomohala ʻenehana maikaʻi loa a ʻeleu hoʻi ma ka ʻoihana mea hana. Wahi a nā koi ukana, ua ulana pololei ʻia ka fiber hoʻoikaika i loko o kahi hale me kahi ʻano ʻekolu-dimensional, a ua like ke ʻano me ke ʻano o ka huahana composite i hoʻokumu ʻia. Hiki i ka lole ʻekolu ʻaoʻao i hoʻohana ʻia i ke kaʻina pultrusion ke lanakila i ka shear interlaminar o nā huahana pultrusion fiber hoʻoikaika kuʻuna. Loaʻa iā ia nā hemahema o ka ikaika haʻahaʻa haʻahaʻa a me ka maʻalahi o ka delamination, a he kūpono loa kāna hana interlayer. (Kumu: Fiberglass Composite / Composites Community)
