ʻEhia mau papa o ka moena kaula i ʻoki ʻia? Kaumaha-a-mānoanoa, me nā helu maoli

E nīnau i ʻelima mau mea hoʻolako i ka nui o nā papa o ka moena kaula i ʻoki ʻia āu e pono ai no kahi laminate 3 mm a loaʻa paha iā ʻoe ʻelima mau pane like ʻole. ʻAʻole ia no ka mea ua hewa kekahi - no ka mea ua hūnā ka nīnau i kahi nīnau ʻelua: pehea ka mānoanoa o hoʻokahi papa? A ʻo ka mānoanoa o kahi ply hoʻōla hoʻokahi o CSM ʻaʻole ia he waiwai paʻa o ka moena. Aia ia i ka nui o ka resin āu e huki ai ma o ia mea a me ka paʻakikī o kāu ʻōwili ʻana. ʻO nā helu i paʻi ʻia no ka papa like 450 g/m², no ka laʻana, mai kahi o 0.9 mm a i kahi o 1.15 mm no kēlā me kēia papa - kahi pālahalaha kokoke i 30% - no ka mea ua manaʻo nā kumu like ʻole i nā lakio resin-a-aniani like ʻole.

Hāʻawi kēia ʻatikala iā ʻoe i ke kiʻi piha: he aha ka mea e kaohi maoli ai i ka mānoanoa o ka papa hoʻokahi, kahi papa kuhi no nā papa kaumaha maʻamau ʻeiwa, nā laʻana i hana ʻia e hoʻololi i ka mānoanoa o ka pahuhopu i ka helu papa, a me kahi ʻano hana ʻekolu-ʻanuʻu e hoʻoponopono ai i nā helu i kāu hale hana ponoʻī i ʻole ʻoe e hōʻaiʻē i nā kuhi a haʻi.

No ke aha "Ehia mau papa" ʻaʻohe pane hoʻokahi

Manaʻo ʻia he mana ko ka pakuhi mānoanoa no ka mea e paʻi ana i nā helu pololei. Akā, ʻo kēlā me kēia mānoanoa o ka ply i paʻi ʻia he kuhi i kūkulu ʻia ma luna o ʻelua mau kuhiakau: ka hapa nui o ka fiber a ka mea kākau e manaʻo ai mai ke kaʻina hana, a me ka compaction a ka mea kākau e manaʻo ai mai ka laminator. E hoʻololi i kekahi kuhiakau a ʻo ka moena like e hana i kahi mānoanoa i hoʻōla ʻia.

ʻO ka mea hoʻolako e hoʻopuka ana i nā waiwai i helu ʻia e hōʻike pinepine i kēia. Hoʻokahi mea hoʻolako ʻEulopa, no ka laʻana, e helu ana i kāna mau helu mānoanoa no kēlā me kēia papa ma ke ʻano he "nā waiwai i helu ʻia ma 15 vol.% fiber content" a hoʻomaopopo koke ʻo ia he ʻokoʻa ka mānoanoa maoli me ka nui o ka resin, ka hana ʻana a me ka compaction. Hōʻike nā kumu i kuhikuhi ʻia i ka hale hana i nā helu haʻahaʻa iki no nā papa like no ka mea hōʻike lākou i ka hana lima maʻamau, kahi e ʻōwili ai ka ʻōwili i ka resin keu a ʻoi aku ka kiʻekiʻe o ka fiber content. ʻAʻole hewa kekahi o nā helu; pane lākou i nā nīnau like ʻole.

No laila, ʻo ke ʻano pono o ka nīnau ʻaʻole "ehia mau papa no X mm?" akā "ehia mau papa ma lalo o kaʻu lakio resin a me kaʻu ʻōwili ʻana?" - ʻo ia ke kumu e pau ai kēia ʻatikala me kahi ʻano hoʻoponopono ma mua o kahi pakuhi paʻa.

ʻO ke kaawale ma waena o nā kuhiakau he hopena kālepa, ʻaʻole wale nā mea loea. Inā kūkulu ʻia kahi ʻōlelo kūʻai ma kahi manaʻo ply 0.9 mm a loaʻa i ka papahele ka 1.15 mm me kāna mau ʻano resin, puka mai ka laminate he 0.75 mm oversize ma kahi kūkulu ʻeono-ply - kūʻai ʻia ke aniani keu, hui pū ʻia ka resin keu, hoʻouna ʻia ke kaumaha keu. ʻOi aku ka ʻino o ka hewa hope: kahi ʻōlelo kūʻai e manaʻo ana ʻo ka ply mānoanoa ma lalo o ke kūkulu ʻana i ka ʻāpana, a ʻike wale ʻia ka hemahema ma ka nānā hope loa, i ka wā ʻo ka hoʻoponopono haʻahaʻa loa he ply keu piha ma luna o ka ʻili holoʻokoʻa. ʻO ke kākau ʻana i ka mānoanoa ply i manaʻo ʻia i loko o ka ʻōlelo kūʻai, ma ka ʻaoʻao o ka pahuhopu, ʻo ia ka paukū ʻaelike haʻahaʻa loa hiki i ka mea hana ke hoʻohui.

He aha ka mea e hoʻoholo ai i ka mānoanoa o hoʻokahi papa

Ma hope o ka hoʻōla ʻana, ʻo ka mānoanoa o hoʻokahi papa CSM mai ka nui o nā mea āpau āu i kau ai i lalo: ke aniani me ka resin, me ka ea i ʻōwili ʻia. ʻO ka nui o nā olonā aniani ma kahi o 2.55 g/cm³; aia ka resin polyester i hoʻōla ʻia ma kahi kokoke i 1.2 g/cm³. ʻO ka moena kaula i ʻoki ʻia he mea hoʻoikaika waiwai resin kūlohelohe - ʻo nā laminates waiho lima e pau pinepine ma kahi o 25-35% aniani ma ke kaumaha, ʻoi aku ka haʻahaʻa ma mua o ka mea i loaʻa i nā lole ulana - no ka mea, ʻo ke ʻano o ka fiber bulky a random e hoʻopaʻa i ka nui o ka resin ma waena o nā kaula.

ʻO kēlā mahele resin ka mea e loli ai. Hōʻike pū nā pakeneka kaumaha a me nā pakeneka leo i nā moʻolelo like ʻole: no ka mea, ʻoi aku ka pālua o ka mānoanoa o ke aniani ma mua o ka resin, ʻo ka laminate he 28% aniani ma ke kaumaha he 15% aniani wale nō ma ka leo. No laila, ʻelua mau kumu e ʻōlelo ana "15 vol%" a me "30 wt%" no ka papa like e wehewehe ana i ka laminate like, ʻaʻole kūʻē kekahi i kekahi.

Mai kēia mau mānoanoa hiki iā ʻoe ke helu i kahi kuhi iā ʻoe iho. Me W ke kaumaha moena ma g/m² a me r ka lakio kaumaha resin-a-aniani (ma kahi o 2.0-2.5 no ka waiho lima ʻana ma luna o ka moena), ʻo ka mānoanoa o ka ply i hoʻōla ʻia ma millimeters ma kahi o:

t ≈ W × (0.39 + 0.83 × r) / 1000

ʻElua mau hoʻāʻo noʻonoʻo e kūʻē i nā helu i paʻi ʻia: ma r = 2.5, hana ʻo 300 g/m² i kahi o 0.74 mm - kūlike me ka 0.7–0.77 mm i ʻōlelo ʻia e nā mea hoʻolako no kēlā papa. Ma r = 2.0, hāʻawi ʻo 450 g/m² ma kahi o 0.93 mm - pololei i loko o ka pae 0.9–1.1 mm i ʻōlelo pinepine ʻia no ka hoʻomoe lima. ʻAʻole he kūlana hou ke ʻano; he ala maopopo ia e ʻike ai i ke kuhi e hana ana i ka helu.

ʻEkolu mau levers pono e hoʻoneʻe iā ʻoe ma kēlā pae:

1. Ka lakio o ka resin.ʻO ka hui ʻana me ka pōloli a me ka pulu ʻana me ka palupalu e pahu iā r i 2.5 a hoʻohui i ka mānoanoa o ka resin maʻemaʻe.
2. Kaomi ʻōwili.Hoʻopaʻa ka ʻōwili hoe i hana maikaʻi ʻia i ka ply, ʻomi i nā hakahaka a me ka resin keu, a hoʻopaʻa iā ʻoe ma kahi kokoke i ka hopena lahilahi o ke ana.
3. Kaʻina hana.ʻO ka hoʻokomo ʻana i ka vacuum-backing a me ka infusion e hoʻopili hou aku i ka stack - ʻo nā helu i ʻōlelo pinepine ʻia he 12% ka lahilahi ma mua o ka hoʻopaʻa lima ʻana ma lalo o ka vacuum a ma kahi o 20% ma lalo o ka infusion. E mālama i kēlā mau pakeneka ma ke ʻano he alakaʻi pae mea hoʻolako, ʻaʻole nā kānāwai o ka physics.

Holo ka helu like i hope i ke kauoha ʻana i nā mea, kahi e mālama ai ka helu ʻana i nā papa a i ʻole ke kumukūʻai. Ke hoʻonohonoho ʻia ka waiho ʻana - e ʻōlelo i ʻekolu mau plies o 450 g/m² ma luna o kahi ʻōmole 40 m² - ʻo ka moena e kauoha ai he wahi × plies wale nō, me kahi ʻae ʻoki no ke ʻano o ka ʻōmole. Hiki i nā mea hana piʻo paʻakikī ke hoʻopau maʻalahi i ka 15-20% ʻoi aku ka moena ma mua o ka ʻili o ka ʻupena, no ka mea, ʻaʻole hiki ke hoʻohana hou ʻia nā ʻoki a puni nā kaha hohonu; ʻoi aku ka liʻiliʻi o ka hoʻopau ʻana o nā panela pālahalaha nui. ʻO ke kauoha ʻana ma ka lōʻihi o ka ʻōwili e kūʻē i kēlā helu, ma mua o ka manaʻo maʻamau, ʻo ia ka mea e pale ai i kahi hale hana hana mai ka hoʻopau ʻana i kahi hana me kahi laminate i hoʻopau ʻia a ʻaʻohe ʻōwili like ma ka papa.

ʻEmi ka nui o nā papa kaumaha a i ʻole nā papa māmā?

Pono ke kālepa i kāna ʻāpana ponoʻī, no ka mea, e launa pū ana me kahi kīnā e hoʻonui ai i nā ana mānoanoa: ka ea i paʻa.

He ʻano hāʻule maoli ka "mānoanoa wahaheʻe".ʻO nā hakahaka - nā ʻeke ea liʻiliʻi i waiho ʻia ma waena o nā olonā kahi i pau ʻole ai ka pulu ʻana a i ʻole ka ʻōwili ʻana - e hoʻohui i ka mānoanoa hiki ke ana ʻia akā ʻaʻohe waiwai kūkulu. Hiki i kahi ʻāpana ke puka mai ka ʻōmole ma ka mānoanoa kikoʻī a hana maikaʻi ʻole, no ka mea, ma ka pepa, ʻaʻole hana nā olonā i ka hana a ka mānoanoa e hōʻike nei. He maʻalahi ka hoʻāʻo ʻike maka a kūpono ke aʻo ʻana i kēlā me kēia laminator: huli ka CSM pulu pono i ka translucent; ʻo kēlā me kēia ʻāpana keʻokeʻo he aniani maloʻo a i ʻole ka ea paʻa e pono ai ke ʻōwili ma mua o ka iho ʻana o ka papa aʻe.

Hoʻopili maikaʻi ʻia nā papa lahilahi.ʻO kēlā me kēia ply 300 g/m² e hōʻike ana i ka nui o ka fiber liʻiliʻi no ka hana ʻana o ka wili, no laila ke kūkulu ʻia nei kahi multi-ply hoʻopaʻa ʻia e pili ana i ka hopena haʻahaʻa o ka pae mānoanoa me nā hakahaka liʻiliʻi. Hoʻoikaika nā papa kaumaha i ka pilikia: emi ka ʻōwili ʻana no kēlā me kēia anakahi o ke aniani, a me kahi ply pulu a mānoanoa hoʻi e maʻalahi ke hoʻopau ʻia ma ka interface.

Akā, hoʻokele ka mānoanoa i ka paʻakikī i ʻāpana ʻia.I loko o kahi kumu hoʻohālike kūlou-ʻoʻoleʻa i hoʻomaʻalahi ʻia, piʻi ka ʻoʻoleʻa me ka cube o ka mānoanoa laminate - ʻo kahi ʻāpana 10% lahilahi ma mua o ka mea i hoʻolālā ʻia e hāʻawi ana ma kahi o 27% o kona ʻoʻoleʻa kūlou ma kēlā kumu hoʻohālike. ʻO ia ke kumu e alualu ai i kahi pahuhopu mānoanoa me ka "resin hou aku" he pahele: hoʻohui ka resin keu i ka mānoanoa kino, akā ʻoi aku ka maʻalahi o ka resin ma mua o ke aniani, no laila he liʻiliʻi ka loaʻa ʻana o ka ʻoʻoleʻa a he ʻoiaʻiʻo ka hoʻopaʻi kaumaha. Pono ka mānoanoa mai ka fiber, ʻaʻole mai kahi waihona resin.

A he mau palena ko ka laminate moena wale nō.ʻO ka moena kaula i ʻoki ʻia he quasi-isotropic a waiwai i ka resin ma ka hoʻolālā - he hapa wale nō o kona fiber e hana ana i kekahi ʻaoʻao hoʻokahi, no laila ma ke kaumaha like ʻaʻole hiki ke hoʻokūkū i ka ulana roving no ka ikaika kuhikuhi. ʻO ka moena ka mea hana kūpono no ka conformability, isotropic behavior a me nā ʻili i hoʻopaʻa ʻia, pale i ka haki; ke kāhea kahi hoʻolālā no ka ikaika kuhikuhi ma ke kaumaha liʻiliʻi, hoʻopili pinepine ʻia nā papa moena me ka ulana roving ma mua o ka hoʻopaʻa ʻia ʻana.

E hoʻoponopono i nā ʻanuʻu ʻekolu

E lilo nā mea a pau i luna nei i mea pono maoli ke pani ʻoe i nā kuhi maʻamau me kāu kumu i ana ʻia. Hoʻokahi awakea ia:

Mai ia manawa aku, hoʻohana nā helu papa no nā pahuhopu mānoanoa hou i kāu kumu, ʻaʻole na ka mea hoʻolako. Inā neʻe ʻoe ma hope i ka vacuum bagging a i ʻole ka infusion, e holo hou i ka coupon - ʻo ke kaomi ʻana a kēlā mau kaʻina hana e pili ana i ke ʻano o nā kumu hoʻopaʻa lima ma mua o ka wānana ʻana i ka mānoanoa.

ʻAʻole hana hoʻokahi wale nō ka hoʻoponopono ʻana. ʻO nā ʻāpana resin, ka mahana o ka hale kūʻai ma nā kau like ʻole, a me ke kapa ʻana o ka roller e hoʻoikaika i ka lakio resin kūpono, no laila ke holo hou nei i ka coupon i kēlā me kēia manawa e loli ai kahi loli - kahi mea hoʻolako resin hou, kahi neʻe ʻana mai ke kauwela a i ka hoʻoilo, kahi hui hou ma nā rollers - e mālama pono i ka mea. ʻO nā hale kūʻai e hoʻopaʻa ana i kēlā me kēia mea o ka coupon me ka lā a me ka ʻāpana resin e kūkulu i kahi ʻikepili liʻiliʻi e hoʻololi i nā paio mānoanoa me nā mea kūʻai aku i kahi nānā ʻelima mau minuke ma kahi o ka hoʻopaʻapaʻa. ʻO ke kumukūʻai o ka maʻamau i hoʻokahi awakea i kēlā me kēia kau a kākau mālie i kēlā me kēia ʻōlelo hoʻohiki mānoanoa ma ka puke kauoha.

Nā nīnau i nīnau pinepine ʻia

Pehea ka mānoanoa o hoʻokahi papa o ka moena kaula i ʻoki ʻia he 450 gsm?

Ma kahi o 0.9–1.1 mm i ka waiho lima ʻana, me ka resin: aniani ma waena o 2:1 a me 2.5:1. ʻO nā waiwai i helu ʻia i paʻi ʻia ma nā ʻāpana leo fiber haʻahaʻa e holo iki aʻe, kokoke i 1.15 mm. ʻO ka pane pololei he laulā, ʻaʻole he kiko: e ana i hoʻokahi coupon i hoʻōla ʻia ma kāu laina ponoʻī a e loaʻa iā ʻoe kahi helu ʻoi aku ka maikaʻi ma mua o kekahi pakuhi.

Hiki iaʻu ke kūkulu i koʻu mānoanoa a pau me ka moena wale nō?

Hiki iā ʻoe, a no nā ʻāpana isotropic, curved a i ʻole nā ʻāpana koʻikoʻi o ka ʻili, pono pinepine ʻoe. ʻO ke kumukūʻai ke kaumaha: ʻo nā laminates mat e lawe i ʻelua a ʻelua a me ka hapa manawa o ko lākou kaumaha aniani i loko o ka resin, no laila ʻoi aku ke kaumaha o kahi ʻāpana mat-wale nō a ʻoi aku ka paʻakikī ma mua o ka laminate i ulana ʻia o ka mānoanoa like. No nā ʻāpana kūkulu kahi e koʻikoʻi ai ka paʻakikī no kēlā me kēia kilo, e hoʻopili i ka mat me ka ulana roving ma kahi o ka stacking mat wale nō.

ʻO ke ʻano o ka laminate waiwai i ka resin he laminate nāwaliwali?

ʻAʻole ia he mea hana maʻalahi - ʻo ia hoʻi ke kaulike ʻokoʻa. Hāʻawi ke aniani i ka ikaika; hoʻopiha, sila a hoʻopaʻa i nā papa resin. Waiwai ka resin i nā laminates mat no ka mea ʻo ko lākou ʻano maʻamau a nui e pono ai ka resin e hoʻopuni i kēlā me kēia kaula, a ma ke kūkaʻi ʻana e kūlike lākou me nā ʻōmole paʻakikī, kūʻē i ka paʻi ʻana a hana i nā hoʻoponopono kala. ʻO ke ʻano hāʻule e pale aku ai ʻaʻole "waiwai" akā "voided": ʻo nā ʻeke ea ka mea e hoʻonāwaliwali maoli ai i kahi laminate, ʻo ia ke kumu e ʻoi aku ai ka nui o ka hoʻopaʻi ʻōwili ma mua o ka ratio resin ponoʻī.

E koho i nā māka, a laila e hōʻoia ma kāu ʻōmole

ʻO kahi maʻamau hope loa e pono ke mālama ʻia: i ka wā e loli ai ke kaha kiʻi - ua hoʻoponopono hou ʻia kahi callout mānoanoa, ua hoʻololi ʻia kahi laminate i kahi resin ʻē aʻe - e holo hou i ka kuhi ma mua o ke kauoha mea, ʻaʻole ma hope.
