Yakanyanya Kubudirira Yakagadziridzwa Material: Girazi Fiber Yakasimbiswa Yakagadziriswa Phenolic Resin (FX-501)

Nekukurumidza kukura mumunda weinjiniya girazi fiber yakasimbiswa mapurasitiki,phenolic resin-based zvinhuakashandiswa zvakanyanya mumaindasitiri akasiyana siyana. Izvi zvinokonzerwa nemhando yavo yakasiyana-siyana, simba remagetsi repamusoro, uye kushanda kwakanaka. Imwe yezvakakosha zvinomiririra zvinhu ndeyephenolic girazi fiber resin zvinhu.

Phenolic girazi fiber, pakati pekutanga maindasitiri ekugadzira resins, inowanzoita polycondensate inoumbwa ne polymerization ye phenols uye aldehydes pamberi pe alkaline catalyst. Zvimwe zvinowedzerwa zvinobva zvaunzwa kuyambuka-kubatanidza iyo macromolecular chimiro, ichichishandura kuita isingagoneki uye isingagoneki matatu-dimensional macromolecular chimiro, nekudaro ichiva chakajairwa.thermosetting polymer zvinhu. Phenolic resins inokosheswa zvakanyanya kune yavo yakatanhamara zvivakwa, zvinosanganisira yakanakisa murazvo retardancy, dimensional kugadzikana, uye yakanaka mechanic simba. Aya hunhu akasimudzira tsvakiridzo yakakura uye kushandiswa kwephenolic girazi fiber resin zvinhu.

Sezvo hupfumi hwemaindasitiri huchifambira mberi nekukurumidza, kuwedzera kudiwa kunoiswa pakuita kwephenolic girazi fiber zvinhu. Naizvozvo,yakakwirira-simba uye inodzivirira kupisa yakagadziridzwa phenolic glass fibersari kugadzirwa zvakanyanya uye kushandiswa.Girazi faibha yakasimbiswa yakagadziridzwa phenolic resin (FX-501)parizvino ndeimwe yeakanyanya kubudirira akagadziridzwa phenolic girazi fiber resin zvinhu. Irwo rudzi rutsva rwezvakagadziridzwa uye zvakasimbiswa phenolic zvinhu zvakagadzirwa nekubatanidza girazi fibers mune yepakutanga resin matrix kuburikidza nekusanganiswa.

 Mechanical Properties uye Constituent Mabasa

Phenolic girazi fiber resininowanzosarudzwa sematrix yekupfeka-resistant, tensile, uye compressive zvinhunekuda kwesimba rayo rakanaka rekusimba, kusagadzikana kwekunyungudutsa, uye yakanakisa michina zvinhu senge flame retardancy. Thematrix zvinhuinonyanya kushanda sebhainda, organically inobatanidza zvikamu zvose.Girazi fibersanoshanda semahombe-anotakura mayuniti muzvinhu zvinopfekwa, achipa hutakuri hwekutakura, uye kuita kwavo kwepamusoro kunokanganisa zvakananga kusimba kweiyo matrix.

Basa rematrix zvinhu nderekusunga zvakasimba zvimwe zvikamu zvezvinhu zvinorema, kuve nechokwadi chekuti mitoro inofambiswa zvakafanana, kugovaniswa, uye kugoverwa kune akasiyana magirazi fiber. Izvi zvinopa imwe simba uye kuomarara kune izvo zvinhu. Mafibisi akajairika, anosanganisira girazi fibers, organic fibers, simbi fibers, uye mineral fibers, anoita basa mukugadzirisa kusimba kwekusimba kwechinhu.

 Kutakura Kutakura muComposites uye Impact yeFiber Content

In phenolic girazi fiber composite zvinhuzvirongwa, zvosefiber uye matrix resin inotakura mutoro, ine magirazi mafiber akasara ari ekutanga anotakura. Kana phenolic girazi refiber composites rinoiswa pasi pekukotama kana kudzvinyirira kushushikana, kushushikana kunotamiswa zvakafanana kubva kune matrix resin kune yega girazi fibers kuburikidza neiyo interface, zvinobudirira kuparadzira simba rinotakurwa. Iyi nzira inovandudza ma mechanical properties ye composite material. Naizvozvo, kuwedzera kwakakodzera mugirazi fiber yemukati inogona kuwedzera kusimba kwephenolic girazi fiber composite.

Zviyedzo zvinoratidza zvinotevera:

• Phenolic girazi faibha macomposites ane 20% girazi fiber contentkuratidza kusaenzana kwefiber kugovera, nedzimwe nzvimbo dzichitoshaya mafiber.
• Phenolic glass fiber composites ine 50% girazi fiber contentratidza yunifomu faibha kugovera, kusajairika kwakatyoka nzvimbo, uye hapana akakosha zviratidzo zveyakawanda fiber kudhonza-kunze. Izvi zvinoratidza kuti magirazi fibers anogona pamwechete kutakura mutoro, zvichikonzerayakakwirira flexural simba.
• Kana iyo girazi fiber yemukati iri 70%, iyo yakawandisa fiber yemukati inotungamira kune yakaderera matrix resin yemukati. Izvi zvinogona kukonzera "resin-varombo" zviitiko mune dzimwe nzvimbo, zvichikanganisa kutamisa kushushikana uye kugadzira kushushikana kwenzvimbo. Nekuda kweizvozvo, iyo yakazara mechanic zvimiro zve phenolic girazi fiber composite zvinhudzinoita kudzikira.

Kubva pane izvi zvakawanikwa, theyakanyanya kubvumidzwa kuwedzera kwegirazi fiber mune phenolic girazi fiber composite i50%.

 Kuvandudza Kuita uye Kufurira Zvinhu

Kubva pane nhamba data,phenolic girazi fiber compositesine 50% yegirazi fiberkuratidza anengekatatu simba rekushanduka-shandukauyekakapetwa kane simba rekumanikidzakuenzaniswa ne pure phenolic resin. Pamusoro pezvo, zvimwe zvinhu zvinopesvedzera kusimba kwephenolic girazi fiber yakasimbiswa mapurasitiki anosanganisira iyokureba kwegirazi fibersuye yavoorientation.
