Fiberglass Reinforced Polymer (GFRP)yog cov khoom siv ua haujlwm siab ua ke los ntawm cov iav fibers ua tus neeg sawv cev txhawb zog thiab cov khoom siv polymer ua cov matrix, siv cov txheej txheem tshwj xeeb. Nws cov qauv tseem ceeb muaj cov iav fibers (xws liE-iav, S-iav, los yog lub zog siab AR-iav) nrog txoj kab uas hla ntawm 5∼25μm thiab cov thermosetting matrices zoo li epoxy resin, polyester resin, lossis vinyl ester, nrog cov ntim fiber ntau feem ntau ncav cuag 30%∼70% [1-3]. GFRP nthuav tawm cov khoom zoo xws li lub zog tshwj xeeb tshaj 500 MPa / (g / cm3) thiab cov qauv tshwj xeeb tshaj 25 GPa / (g / cm3), thaum tseem muaj cov yam ntxwv zoo li corrosion tsis kam, qaug zog tsis kam, qis coefficient ntawm thermal expansion [(7∼12) × 10-6 ° C−1], thiab electromagnetic transparency.

Hauv thaj chaw aerospace, daim ntawv thov ntawm GFRP tau pib hauv xyoo 1950 thiab tam sim no tau dhau los ua cov khoom tseem ceeb rau kev txo cov qauv tsim thiab txhim kho roj efficiency. Ua piv txwv ntawm Boeing 787, GFRP suav txog 15% ntawm nws cov qauv tsis yog cov khoom siv thauj khoom, siv hauv cov khoom xws li fairings thiab winglets, ua tiav qhov hnyav ntawm 20% ∼ 30% piv rau cov tsoos aluminium alloys. Tom qab cov kab hluav taws xob hauv pem teb ntawm Airbus A320 tau hloov nrog GFRP, qhov loj ntawm ib qho kev tivthaiv tau txo qis los ntawm 40%, thiab nws cov kev ua tau zoo hauv qhov chaw ntub dej tau txhim kho. Nyob rau hauv lub nyoob hoom qav taub sector, lub sab hauv vaj huam sib luag ntawm Sikorsky S-92's alarm siv GFRP honeycomb sandwich qauv, ua tiav qhov sib npaug ntawm qhov cuam tshuam thiab nplaim hluav taws xob (ua raws li FAR 25.853 tus qauv). Piv nrog rau Carbon Fiber Reinforced Polymer (CFRP), tus nqi raw khoom ntawm GFRP raug txo los ntawm 50% ∼70%, muab kev lag luam tseem ceeb hauv cov khoom tsis yog cov khoom lag luam. Tam sim no, GFRP tab tom tsim cov khoom siv gradient daim ntawv thov nrog cov pa roj carbon fiber ntau, txhawb kev txhim kho cov khoom siv dav hlau mus rau lub teeb yuag, lub neej ntev, thiab tus nqi qis.

Los ntawm kev pom ntawm lub cev muaj zog,GFRPkuj muaj qhov zoo tshaj plaws ntawm kev sib sib zog nqus, thermal zog, corrosion kuj, thiab functionalization. Hais txog lub teeb yuag, qhov ntom ntawm iav fiber ntau li ntawm 1.8∼2.1 g / cm3, uas tsuas yog 1/4 ntawm cov hlau thiab 2/3 ntawm aluminium alloy. Hauv kev sim kev kub ntxhov siab, lub zog tuav tau tshaj 85% tom qab 1,000 teev ntawm 180 ° C. Tsis tas li ntawd, GFRP immersed nyob rau hauv 3.5% NaCl tov rau ib xyoos tau pom lub zog poob qis dua 5%, thaum Q235 steel muaj qhov hnyav poob ntawm 12%. Nws cov kua qaub tsis kam yog qhov tseem ceeb, nrog kev hloov pauv huab hwm coj qis dua 0.3% thiab qhov ntim nthuav dav qis dua 0.15% tom qab 30 hnub hauv 10% HCl tov. Silane-kho GFRP cov qauv khaws cia lub zog khoov siab tshaj 90% tom qab 3,000 teev.

Hauv cov ntsiab lus, vim nws qhov tshwj xeeb ua ke ntawm cov khoom, GFRP tau dav siv los ua cov khoom siv dav hlau ua haujlwm siab hauv kev tsim thiab tsim cov dav hlau, tuav lub tswv yim tseem ceeb hauv kev lag luam aerospace niaj hnub thiab kev tsim kho thev naus laus zis.
