Fiberglass Reinforced Polymer (GFRP)chinhu chinoshanda zvakanyanya chakagadzirwa kubva kufiber yegirazi sekusimbisa uye polymer resin sematrix, uchishandisa maitiro chaiwo. Chimiro chayo chikuru chine fiber yegirazi (sengeGirazi remagetsi, S-girazi, kana AR-girazi rakasimba) rine dhayamita ye5∼25μm uye thermosetting matrices senge epoxy resin, polyester resin, kana vinyl ester, ine fiber volume fraction inowanzo kusvika 30%∼70% [1-3]. GFRP inoratidza hunhu hwakanaka senge simba rakati wandei rinodarika 500 MPa/(g/cm3) uye modulus chaiyo inodarika 25 GPa/(g/cm3), ukuwo iine hunhu hwakaita sekudzivirira ngura, kuramba kuneta, coefficient yakaderera yekuwedzera kwekupisa [(7∼12)×10−6 °C−1], uye electromagnetic transparency.

Munzvimbo dzendege, kushandiswa kweGFRP kwakatanga kuma1950 uye ikozvino kwave chinhu chakakosha mukuderedza huremu hwemaumbirwo uye kuvandudza mashandiro emafuta. Tichitora Boeing 787 semuenzaniso, GFRP inokwana 15% yezvimiro zvayo zvisiri zvekutanga zvinotakura mutoro, zvinoshandiswa muzvikamu zvakaita semafairing nemawinglets, zvichideredza huremu ne20% ~ 30% zvichienzaniswa nearuminiyamu yechinyakare. Mushure mekunge matanda epasi pekabhini eAirbus A320 atsiviwa neGFRP, huremu hwechikamu chimwe chete hwakaderera ne40%, uye mashandiro ayo munzvimbo dzine hunyoro akavandudzika zvakanyanya. Muchikamu chehelikopta, mapaneru emukati mekabhini yeSikorsky S-92 anoshandisa chimiro chesandwich cheGFRP, zvichienzanisa pakati pekudzivirira kukanganiswa uye kunonoka kwemurazvo (zvichienderana neFAR 25.853 standard). Zvichienzaniswa neCarbon Fiber Reinforced Polymer (CFRP), mutengo weGFRP wezvinhu zvisina kugadzirwa unoderedzwa ne50% ~ 70%, zvichipa mukana wakakura wehupfumi muzvinhu zvisiri zvekutanga zvinotakura mutoro. Parizvino, GFRP iri kugadzira sisitimu yekushandisa zvinhu ine kabhoni fiber, ichikurudzira kuvandudzwa kwemidziyo yemuchadenga kuti iwedzere kurema, kurarama kwenguva refu, uye mutengo wakaderera.

Kubva pamaonero ehunhu hwemuviri,GFRPinewo mabhenefiti makuru maererano nekureruka, hunhu hwekupisa, kuramba ngura, uye kushanda kwayo. Nezvekureruka, huwandu hwegirazi fiber hunotangira pa1.8∼2.1 g/cm3, inova 1/4 chete yesimbi uye 2/3 yealuminium alloy. Mukuyedza kwekukwegura kwakanyanya, chiyero chekuchengetedza simba chakapfuura 85% mushure memaawa chiuru pa180 °C. Uyezve, GFRP yakanyudzwa mumushonga weNaCl we3.5% kwegore rimwe yakaratidza kurasikirwa nesimba kweasingasviki 5%, nepo Q235 simbi yakarasikirwa nehuremu hwekureruka kwe12%. Kudzivirira kwayo acid kwakakosha, ine chiyero chekuchinja kwehukuru chakaderera pane 0.3% uye chiyero chekuwedzera kwevhoriyamu chakaderera pane 0.15% mushure memazuva makumi matatu mumushonga weHCl we10%. Samples dzeGFRP dzakarapwa neSilane dzakaramba dzichichengetedza simba rakakotama kupfuura 90% mushure memaawa zviuru zvitatu.

Muchidimbu, nekuda kwekusanganiswa kwayo kwakasiyana kwezvivakwa, GFRP inoshandiswa zvakanyanya sechinhu chikuru chemuchadenga chinoshanda zvakanyanya mukugadzira nekugadzira ndege, ichikoshesa zvakanyanya muindasitiri yemuchadenga yemazuva ano uye mukuvandudzwa kwetekinoroji.
