ʻO ka mea hoʻoikaika i ka iwi kākoʻo o ka huahana FRP, kahi e hoʻoholo pono 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, i ka wā e hoʻokō ai i nā koi 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 koʻi ʻole ʻana o nā kaula aniani ma mua o nā lole fiber; ke kumukuai omoena fiber anianiʻoi aku ka haʻahaʻa 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. Untwisted aniani puluniu roving

Me ka hoʻohana ʻana i ka mea hoʻonui i hoʻopaʻa ʻia, ʻaʻole i kāwili ʻiaaniani puluniu rovingHiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano: siliki maka, ʻo ka holo pololei ʻole a me ka roving untwisted bulked.

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 o ka hana.

Loaʻa nā hiʻohiʻona o ka paipu maikaʻi, ke komo ʻana o ka resin wikiwiki, a me nā waiwai mechanical maikaʻi o nā huahana, no laila ke hoʻohana ʻia nei ka hapa nui o nā rovings untwisted pololei i kēia manawa.

He mea maikaʻi ka holo ʻana i ka nui no ka hoʻomaikaʻi ʻana i ka ikaika transverse o nā huahana, e like me ka crimped rovings a me ka ea-textured rovings. 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 ka pale wela kiʻekiʻe, 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 wili a me ka ulana no nā lole i ulana ʻia a ʻoihana. Hiki ke hoʻohana ʻia e hana i ka friction, insulation, pale a i ʻole nā ​​​​mea hoʻopaʻa.

Nā koi o ka hana no ka wili aniani fiber rovings no ka pultrusion:

(1) ʻAʻohe hanana overhang;

(2) ʻAʻahu like ke ʻano o ka fiber;

(3) ʻO ka hui maikaʻi;

(4) Kūleʻa maikaʻi i ka lole;

(5) He kakaikahi na poo naha, a aole maalahi ka fluff;

(6) Maikaʻi wettability a me ka wikiwiki resin impregnation;

(7) Ka ikaika kiʻekiʻe a me ka rigidity.

Hoʻopuʻu ʻia ka fiberglass i ka holo ʻana 

2. Moena fiber aniani

I mea e lawa ai ka ikaika transverse o nā huahana FRP pultruded, pono e hoʻohana ʻia nā mea hoʻoikaika e like me ka moena ʻoki ʻoki ʻia, ka moena wili mau, ka moena hui, a me ka lole wili ʻole. 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,moena ilihoʻohana ʻia i kekahi manawa.

ʻO ka moena strand mau i haku ʻia me nā ʻāpana he nui o nā fiber aniani mau i waiho wale ʻia i loko o ka pōʻai, a ua hoʻopaʻa ʻia nā kaula me nā mea hoʻopili. ʻO ka manaʻo o ka ʻili he ʻano pepa lahilahi 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: maikaʻi ka uhi ʻana, maʻalahi ke hoʻopiha ʻia me ka resin, ʻike kiʻekiʻe ke kāpili

ʻO nā koi o ke kaʻina hana pultrusion no ka moena fiber aniani:

(1) Loaʻa i ka ikaika mechanical kiʻekiʻe

(2) No nā moena mānoanoa i kālai ʻia me ke kemika, pono e kūʻē ka mea hoʻopaʻa i nā hopena kemika a me ka wela i ka wā o ka hoʻoluu ʻana a me ka hana mua ʻana e hōʻoia i ka ikaika i ka wā o ke kaʻina hana;

(3) Hiki maikaʻi ka pulu;

(4) Liʻiliʻi liʻiliʻi a liʻiliʻi nā poʻo haki.

3. Polyester fiber ili moena

ʻO ka polyester fiber surface he ʻano hou o ka hoʻoikaika ʻana i nā mea fiber i ka ʻoihana pultrusion. Aia kekahi huahana i kapa ʻia ʻo Nexus ma ʻAmelika Hui Pū ʻIa, i hoʻohana nui ʻia i nā huahana pultruded e pani aimoena ili pulu aniani. 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 moena ʻiʻo polyester fiber:

(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 nā huahana;

(2) Hiki iā ia ke hoʻomaikaʻi i ke kūlana ili o ka huahana a hoʻomāmā i ka ʻili o ka huahana;

(3) ʻOi aku ka maikaʻi o ka noi a me nā waiwai tensile o ka polyester fiber surface ma mua o ka C glass surface i manaʻo ʻia, a ʻaʻole maʻalahi ka haki ʻana i nā hopena i ka wā o ka pultrusion, e hōʻemi ana i nā pōpilikia kaʻa;

(4) Hiki ke hoʻonui i ka wikiwiki pultrusion;

(5) Hiki iā ia ke ho'ēmi i kaʻaʻahu o ka'ōpala a hoʻonui i ke ola lawelawe o ka'ōpala

4. Lipine lole fiber aniani

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. Hoʻohana i nā lole ʻelua a me nā lole ʻekolu

ʻAʻole maikaʻi nā ʻano mīkini transverse o nā huahana pultruded composite, a ʻo ka hoʻohana ʻana i ka braiding bidirectional e hoʻomaikaʻi maikaʻi i ka ikaika a me ka ʻoʻoleʻa 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 i 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 ka huahana composite i hoʻokumu ʻia. Hoʻohana ʻia ka lole ʻekolu ala i ke kaʻina pultrusion e lanakila ai 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 ʻoi aku ka maikaʻi o kāna hana interlayer.
