What is G.R.P 什麼是玻璃纖維?


The formal name for fiberglass is called Glassfibre Reinforced Polyester or GRP/FRP in short. GRP is a strong and durable material, they can be applied in a wide range of building and construction applications.

G.R.P. are structural products comprising a combination of dissimilar constituent materials. The overall engineering performance characteristics of a finished composite far exceed those achievable from any of the individual components used in isolation.

GRP generally consists of high tensile strength glassfibre protected by high quality unsaturated polyester resin. The term composite more accurately describes the products manufactured by today's fiberglass industry in Hong Kong. High performance resins (normally polyester or epoxy) are combined in a mould with high strength fiberglass to form a final product.

Benefits of G.R.P.

GRP is the ideal material for infrastructure uses and all types of specialist construction. The major benefits of GRP can be summarized as:

玻璃纖維之數種特性分別說明於後:

(1)高拉伸強度:與其他紡織纖維比較,玻璃纖維有特異之高拉伸強度,它的強度與重量比(σ/ρ)超過剛絲在某方面之應用。

(2)耐熱及耐火性:因玻璃纖維是無機化合物,故它不自燃亦不助燃。

(3)耐化學性:對部分化學品,玻纖有相當優異之耐化學性,而對蕈、細菌、或昆蟲之攻擊亦相當遲鈍。

(4)抗濕性:玻璃不吸收水分,它既不膨脹亦不拉長及不分解,玻璃纖維不會迅速腐壞,在濕的環境下持續保持一貫的機械強度。

(5)熱性質:由於低的熱線性膨脹係數和高的熱傳導係數,因而在熱環境下玻璃纖維顯現優越的功能。

(6)電性:玻璃是非導電性,對於電性絕緣是理想的材料,所製成之產品具有高介電強度及低介電損失性質
