Polymer gbasiri ike na fiberglass (GFRP)bụ ihe na-arụ ọrụ dị elu nke sitere na iko iko dị ka onye na-agba ume na polymer resin dị ka matrix, na-eji usoro a kapịrị ọnụ. Nhazi ya nwere eriri iko (dịkaE-iko, S-glass, ma ọ bụ elu-ike AR-glass) na dayameta nke 5∼25μm na thermosetting matrices dị ka epoxy resin, polyester resin, ma ọ bụ vinyl ester, na a eriri olu ntakiri a na-eru 30% ~ 70% [1-3]. GFRP na-egosiputa ihe ndị dị mma dị ka otu ike karịrị 500 MPa / (g / cm3) na modul dị iche iche gafere 25 GPa / (g / cm3), ebe ọ na-enwekwa àgwà dị ka nguzogide corrosion, ike ọgwụgwụ, obere ọnụọgụ nke mgbasawanye okpomọkụ [(7∼12) × 10-6 ° C-1], na nghọta electromagnetic.

N'ebe aerospace, ngwa nke GFRP malitere na 1950s ma bụrụzi ihe dị mkpa maka ibelata nhazi nhazi yana imeziwanye arụmọrụ mmanụ. Na-ewere Boeing 787 dị ka ihe atụ, GFRP na-aza 15% nke ihe owuwu na-ebu ibu na-abụghị nke mbụ, nke a na-eji na ihe ndị dị ka fairings na winglets, na-enweta mbelata arọ nke 20% ~ 30% ma e jiri ya tụnyere omenala aluminom alloys. Mgbe ejiri GFRP dochie ọnụ ala ụlọ nke Airbus A320, oke otu akụrụngwa belatara site na 40%, yana arụmọrụ ya na gburugburu iru mmiri na-akawanye mma. Na mpaghara helikopta, akụkụ ime ụlọ nke Sikorsky S-92's cabin na-eji usoro Sanwichi mmanụ aṅụ GFRP, na-enweta nguzozi n'etiti nguzogide mmetụta na ire ọkụ (na-agbaso ụkpụrụ FAR 25.853). E jiri ya tụnyere Carbon Fiber Reinforced Polymer (CFRP), ọnụ ahịa akụrụngwa nke GFRP na-ebelata site na 50% ~ 70%, na-enye nnukwu uru akụ na ụba na akụrụngwa anaghị ebu ibu. Ugbu a, GFRP na-etolite sistemu ngwa gradient ihe nwere eriri carbon, na-akwalite mmepe iterative nke akụrụngwa ikuku maka ịdị arọ, ogologo ndụ na ọnụ ala.

Site n'echiche nke ihe anụ ahụ,GFRPnwekwara uru pụtara ìhè n'ihe gbasara ịdị arọ, ihe ọkụ ọkụ, nguzogide corrosion na ịrụ ọrụ. Banyere ịdị arọ, njupụta nke eriri iko sitere na 1.8 ~ 2.1 g / cm3, nke bụ naanị 1/4 nke ígwè na 2/3 nke aluminom alloy. N'ime nnwale ịka nká dị elu, ọnụ ọgụgụ njide ike gafere 85% mgbe awa 1,000 gachara na 180 Celsius. Ọzọkwa, GFRP mikpuru na 3.5% NaCl ngwọta maka otu afọ gosiri mfu ike nke na-erughị 5%, ebe Q235 ígwè nwere corrosion arọ ọnwụ nke 12%. Nguzogide acid ya pụtara ìhè, yana ngbanwe oke dị ala karịa 0.3% yana mmụba olu dị ala karịa 0.15% mgbe ụbọchị 30 gachara na ngwọta 10% HCl.
