ʻO ka mea hoʻoikaika ke iwi kākoʻo o ka huahana FRP, ʻo ia ke kumu e hoʻoholo ai i nā waiwai mechanical o ka huahana pultruded. ʻO ka hoʻohana ʻana i ka mea hoʻoikaika he hopena koʻikoʻi nō hoʻi ia i ka hōʻemi ʻana i ka emi ʻana o ka huahana a me ka hoʻonui ʻana i ka mahana deformation thermal a me ka ikaika hopena haʻahaʻa.

I ka hoʻolālā ʻana o nā huahana FRP, pono e noʻonoʻo pono ke koho ʻana i nā mea hoʻoikaika i ke kaʻina hana hoʻoheheʻe o ka huahana, no ka mea, ʻo ke ʻano, ke ʻano o ke kau ʻana a me ka nui o nā mea hoʻoikaika he mana nui ia i ka hana o nā huahana FRP, a ʻo ia ke kumu e hoʻoholo ai i ka ikaika mechanical a me ka modulus elastic o nā huahana FRP. ʻOkoʻa nō hoʻi ka hana o nā huahana pultruded me ka hoʻohana ʻana i nā mea hoʻoikaika like ʻole.

Eia kekahi, ʻoiai e hoʻokō ana i nā koi hana huahana o ke kaʻina hana hoʻoheheʻe ʻia, pono e noʻonoʻo ʻia ke kumukūʻai, a pono e koho ʻia nā mea hoʻoikaika haʻahaʻa e like me ka hiki. Ma keʻano laulā, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka roving non-picking o nā kaula fiber aniani ma mua o nā lole fiber; ke kumukūʻai omoena anianiʻoi aku ka haʻahaʻa ma mua o ka lole, a maikaʻi ka impermeability. , akā haʻahaʻa ka ikaika; ʻoi aku ka liʻiliʻi o ke kumukūʻai o ka fiber alkali ma mua o ka fiber alkali-free, akā me ka hoʻonui ʻia o ka ʻike alkali, e emi ana kona kūpaʻa alkali, kūpaʻa i ka corrosion, a me nā waiwai uila.

ʻO nā ʻano mea hoʻoikaika i hoʻohana pinepine ʻia penei:

1. Ke kaʻahele ʻana o ka fiber aniani i wili ʻole ʻia

Ke hoʻohana nei i ka mea hoʻonui i hoʻoikaika ʻia, wehe ʻiake kaʻahele ʻana o ke aniani fiberhiki ke puʻunaue ʻia i ʻekolu ʻano: silika maka i wili ʻia, ka roving pololei me ka wili ʻole ʻia, a me ka roving bulked me ka wili ʻole ʻia.

Ma muli o ke kuʻi like ʻole o nā kaula i hoʻopili ʻia, he maʻalahi ke kūlou, kahi e hana ai i kahi loop wehe ma ka hopena hānai o nā lako pultrusion, kahi e hoʻopilikia ai i ka holomua o ka hana.

ʻO ka roving pololei me ka wili ʻole ʻia he mau ʻano o ka bunching maikaʻi, ka komo wikiwiki ʻana o ka resin, a me nā waiwai mechanical maikaʻi loa o nā huahana, no laila ʻo ka hapa nui o nā rovings pololei me ka wili ʻole ʻia e hoʻohana pinepine ʻia i kēia manawa.

He mea maikaʻi nā rovings bulked no ka hoʻomaikaʻi ʻana i ka ikaika transverse o nā huahana, e like me nā rovings crimped a me nā rovings air-textured. Loaʻa i ka rovings bulk ka ikaika kiʻekiʻe o nā olonā lōʻihi hoʻomau a me ka nui o nā olonā pōkole. He mea ia me ke kūpaʻa wela kiʻekiʻe, ka conductivity thermal haʻahaʻa, ke kūpaʻa corrosion, ka mana kiʻekiʻe a me ka pono kānana kiʻekiʻe. Hoʻopili ʻia kekahi mau olonā i loko o 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 ma waho, e like me nā olonā warp a me weft no nā lole ulana hoʻonaninani a ʻoihana paha. Hiki ke hoʻohana ʻia e hana i nā mea friction, insulation, protection a i ʻole sealing.

Nā koi hana no nā rovings fiber aniani i wili ʻole ʻia no ka pultrusion:

(1) ʻAʻohe hanana overhang;

(2) Ua like ke kaumaha o ke olonā;

(3) Puʻupuʻu maikaʻi;

(4) Ke kūpaʻa maikaʻi ʻana i ka ʻaʻahu;

(5) He kakaikahi nā poʻo haki, a ʻaʻole maʻalahi ke hoʻoluliluli;

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

(7) Ikaika a me ka paʻakikī kiʻekiʻe.

Hoʻopuehu ʻia ka fiberglass roving 

2. Moena olonā 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 kaula i ʻoki ʻia, ka moena kaula hoʻomau, ka moena hui pū ʻia, a me ka lole olonā i wili ʻole ʻia. ʻO ka moena kaula hoʻomau kekahi o nā mea hoʻoikaika transverse fiber aniani i hoʻohana nui ʻia i kēia manawa. I mea e hoʻomaikaʻi ai i ke ʻano o nā huahana,moena ʻilihoʻohana ʻia i kekahi manawa.

ʻO ka moena kaula hoʻomau i haku ʻia me kekahi mau papa o nā olonā aniani hoʻomau i hoʻonohonoho pono ʻole ʻia i loko o kahi pōʻai, a ua hoʻopaʻa ʻia nā olonā me nā mea hoʻopili. ʻO ka ʻili i hoʻopaʻa ʻia he ʻili pepa lahilahi i hana ʻia ma ke kau ʻana i nā olonā i ʻoki ʻia o ka lōʻihi paʻa a hoʻopaʻa ʻia me kahi mea hoʻopili. ʻO ka nui o ka olonā he 5% a 15%, a ʻo ka mānoanoa he 0.3 a 0.4 mm. Hiki iā ia ke hoʻolilo i ka ʻili o ka huahana i laumania a nani, a hoʻomaikaʻi i ke kūpaʻa ʻana o ka huahana i ka wā ʻelemakule.

ʻO nā ʻano o ka moena fiber aniani: uhi maikaʻi, maʻalahi ke hoʻopiha ʻia me ka resin, kiʻekiʻe ka nui o ke kāpili

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

(1) Loaʻa ka ikaika mīkini kiʻekiʻe

(2) No nā moena kaula i ʻoki ʻia i hoʻopaʻa ʻia me ke kemika, pono e kūpaʻa ka mea hoʻopaʻa i nā hopena kemika a me ka wela i ka wā e luʻu ai a me ke kūkulu mua ʻana e hōʻoia i ka ikaika kūpono i ka wā o ke kaʻina hana;

(3) Maikaʻi ka pulu ʻana;

(4) ʻOi aku ka liʻiliʻi o ka fluff a me nā poʻo haki.

Moena i humuhumu ʻia me ka fiberglass

Moena hui ʻia o ke aniani

3. Moena ʻili o ka fiber polyester

ʻO ka polyester fiber surface felt kahi ʻano hou o ka mea hoʻoikaika fiber i ka ʻoihana pultrusion. Aia kahi huahana i kapa ʻia ʻo Nexus ma ʻAmelika Hui Pū ʻIa, kahi i hoʻohana nui ʻia i nā huahana pultruded e paninā moena ʻili aniani. He hopena maikaʻi kona a he haʻahaʻa ke kumukūʻai. Ua hoʻohana pono ʻia no nā makahiki he 10 a ʻoi.

Nā pōmaikaʻi o ka hoʻohana ʻana i ka moena tissue fiber polyester:

(1) Hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa hopena, ke kūpaʻa i ka pala a me ke kūpaʻa ʻana o ka lewa o nā huahana;

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

(3) ʻOi aku ka maikaʻi o ka noi a me nā waiwai tensile o ka polyester fiber surface felt ma mua o ka C glass surface felt, a ʻaʻole maʻalahi ka uhaki ʻana i nā wēlau i ka wā o ke kaʻina hana pultrusion, e hōʻemi ana i nā ulia kaʻa;

(4) Hiki ke hoʻonui ʻia ka wikiwiki o ka pultrusion;

(5) Hiki iā ia ke hōʻemi i ke komo ʻana o ka ʻōpala a hoʻomaikaʻi i ke ola lawelawe o ka ʻōpala

4. Lipine lole 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 ikaika transverse.

5. Hoʻopili ʻia nā lole ʻelua-dimensional a me nā lole ʻekolu-dimensional

ʻOi aku ka maikaʻi ʻole o nā waiwai mechanical transverse o nā huahana composite pultruded, a ʻo ka hoʻohana ʻana i ka ulana bidirectional e hoʻomaikaʻi maikaʻi i ka ikaika a me ka ʻoʻoleʻa o nā huahana pultruded.

ʻAʻole i ulana ʻia nā olonā warp a me weft o kēia lole ulana me kekahi i kekahi, akā ua ulana ʻia me kahi mea ulana ʻē aʻe, no laila he ʻokoʻa loa ia mai ka lole aniani kuʻuna. Aia nā olonā ma kēlā me kēia ʻaoʻao i ke kūlana collimated a ʻaʻole hana i kekahi kūlou, a no laila ʻoi aku ka ikaika a me ka paʻakikī o ka huahana pultruded ma mua o ka hui ʻana i hana ʻia me ka felt hoʻomau.

I kēia manawa, ua lilo ka ʻenehana ulana ʻekolu ala i kahua hoʻomohala ʻenehana hoihoi a ikaika loa i ka ʻoihana mea hui. Wahi a nā koi ukana, ua ulana pololei ʻia ka fiber hoʻoikaika i loko o kahi ʻano me kahi ʻano ʻekolu-dimensional, a ua like ke ʻano me ka huahana hui i hana ʻia. Hoʻohana ʻia ka lole ʻekolu ala i ke kaʻina hana pultrusion e lanakila ai i ka ʻoki interlaminar o nā huahana pultrusion fiber hoʻoikaika kuʻuna. Loaʻa iā ia nā hemahema o ka ikaika ʻoki haʻahaʻa a me ka maʻalahi o ka delamination, a kūpono loa kāna hana interlayer.
