Me ka wikiwiki o ka hoʻomohala ʻana i ke kahua o nā plastics i hoʻoikaika ʻia me ke aniani ʻenekinia,nā mea i hoʻokumu ʻia i ka resin phenolicua hoʻohana nui ʻia ma nā ʻoihana like ʻole. ʻO kēia ma muli o ko lākou ʻano kūikawā, ka ikaika mīkini kiʻekiʻe, a me ka hana maikaʻi loa. ʻO kekahi o nā mea hōʻike koʻikoʻi loamea resin fiber aniani phenolic.
ʻO ke aniani phenolic, ma waena o nā resins synthetic mua loa, he polycondensate maʻamau i hoʻokumu ʻia e ka polymerization o nā phenols a me nā aldehydes i ke alo o kahi mea hoʻoulu alkaline. A laila hoʻokomo ʻia kekahi mau mea hoʻohui e hoʻopili i ka ʻano macromolecular, e hoʻololi ana iā ia i loko o kahi ʻano macromolecular ʻekolu-dimensional insoluble a infusible, a laila e lilo i mea maʻamau.mea polymer thermosettingHe waiwai nui nā resins phenolic no ko lākou mau waiwai koʻikoʻi, me ka pale ʻana i ka lapalapa maikaʻi loa, ke kūpaʻa o ka dimensional, a me ka ikaika mechanical maikaʻi. Ua hoʻoikaika kēia mau ʻano i ka noiʻi nui a me ka hoʻohana ʻana i nā mea resin fiber phenolic glass.
I ka holomua wikiwiki ʻana o nā hoʻokele waiwai ʻoihana, ua kau ʻia nā koi e hoʻonui ana i ka hana o nā mea fiber aniani phenolic. No laila,nā olonā aniani phenolic i hoʻololi ʻia me ka ikaika kiʻekiʻe a me ke kūpaʻa welake hoʻomohala nui ʻia nei a hoʻohana ʻia nei.ʻO ka resin phenolic i hoʻololi ʻia i hoʻoikaika ʻia e ke aniani (FX-501)ʻo ia kekahi o nā mea resin fiber phenolic i hoʻololi ʻia i kēia manawa. He ʻano hou ia o nā mea phenolic i hoʻololi ʻia a hoʻoikaika ʻia i hana ʻia ma ka hoʻohui ʻana i nā fibers aniani i loko o ka matrix resin mua ma o ka hui ʻana.
Nā Waiwai Mekanika a me nā Kūlana Kumu
ʻO ka resin fiber aniani phenolicua koho pinepine ʻia ma ke ʻano he matrix nonā mea kūpaʻa i ke kapa, tensile, a me nā mea compressivema muli o kona ikaika tensile maikaʻi, ke kūpaʻa solvent, a me nā waiwai mechanical maikaʻi loa e like me ka pale ʻana i ka lapalapa.mea matrixhana nui ʻia ma ke ʻano he mea hoʻopaʻa, e hoʻopili ana i nā ʻāpana āpau.Nā olonā anianilawelawe ma ke ʻano he mau ʻāpana halihali nui i nā mea kūpaʻa i ke komo ʻana, e hāʻawi ana i ka hiki ke halihali ukana, a ʻo kā lākou hana kiʻekiʻe e hoʻopilikia pololei i ka hopena hoʻoikaika ma ka matrix.
ʻO ke kuleana o ka mea matrix ka hoʻopaʻa pono ʻana i nā ʻāpana ʻē aʻe o ka mea tensile, e hōʻoia ana ua hoʻoili like ʻia nā ukana, hoʻolaha ʻia, a hoʻokaʻawale ʻia i nā olonā aniani like ʻole. Hāʻawi kēia i kahi ikaika a me ka paʻakikī i ka mea. ʻO nā olonā maʻamau, me nā olonā aniani, nā olonā organik, nā olonā kila, a me nā olonā mineral, he kuleana ko lākou i ka hoʻoponopono ʻana i ka ikaika tensile o ka mea.
Ka Hāpai Ukana i nā Composites a me ka Hopena o ka ʻIke Fiber
In mea hui pū ʻia o ke aniani phenolicnā ʻōnaehana, ʻo nā mea ʻeluake kaumaha o nā olonā a me ka resin matrix, me nā olonā aniani e waiho ana i ka mea lawe ukana mua. Ke hoʻokau ʻia nā hui olonā aniani phenolic i ke kaumaha kūlou a i ʻole ke kaumaha compression, ua hoʻoili like ʻia ke kaumaha mai ka resin matrix i nā olonā aniani pākahi ma o ka interface, e hoʻopuehu pono ana i ka ikaika i lawe ʻia. Hoʻomaikaʻi kēia kaʻina hana i nā waiwai mechanical o ka mea hui. No laila, kahi hoʻonui kūpono ihiki i ka ʻike o ka fiber aniani ke hoʻonui i ka ikaika o nā composites fiber aniani phenolic.
Hōʻike nā hopena hoʻokolohua i kēia mau mea:
- Nā hui pū ʻia o ke aniani phenolic me 20% o ka nui o ke anianihōʻike i ka hoʻolaha like ʻole o ka fiber, me kekahi mau wahi i nele i nā fiber.
- Nā hui pū ʻia o ke aniani phenolic me 50% o ka nui o ke anianihōʻike i ka hoʻolaha like ʻana o ke olonā, nā ʻili haki ʻano ʻole, a ʻaʻohe hōʻailona koʻikoʻi o ka huki nui ʻana o ke olonā. Hōʻike kēia e hiki i nā olonā aniani ke hāpai pū i ka ukana, e hopena anaikaika flexural kiʻekiʻe.
- Ke loaʻa ka nui o ke aniani fiber i 70%, ʻo ka nui o ka fiber e alakaʻi ai i kahi ʻike resin matrix haʻahaʻa. Hiki i kēia ke hana i nā hanana "resin-poor" ma kekahi mau wahi, e pale ana i ka hoʻoili ʻana o ke kaumaha a me ka hana ʻana i nā ʻano stress kūloko. No laila, ʻo nā waiwai mechanical holoʻokoʻa o ka mea hui fiber aniani phenolice emi iho ana.
Mai kēia mau ʻike, ʻo kaʻO ka hoʻohui ʻia ʻana o ke aniani fiber i ʻae ʻia i loko o nā composites phenolic glass fiber he 50%.
Hoʻonui Hana a me nā Kumu Hoʻohuli
Mai ka ʻikepili helu,nā hui pū ʻana o ke aniani phenolicaia he 50% fiber anianihōʻike ma kahi oʻekolu manawa o ka ikaika flexurala meʻehā manawa o ka ikaika compressivehoʻohālikelike ʻia me ka resin phenolic maʻemaʻe. Eia kekahi, ʻo nā mea ʻē aʻe e hoʻopilikia ana i ka ikaika o nā plastics i hoʻoikaika ʻia me ka fiber phenolic glass e komo pū me kaka lōʻihi o nā olonā aniania me kā lākoukuhikuhi ʻana.
