FRP采光板的英文名字是Fibreglass Reinfored Polyester，翻譯成中文就是玻璃纖維強(qiáng)化聚酯（采光板），俗稱玻璃鋼，習(xí)慣上以其手寫字母FRP簡稱。國外還有一種叫法GRP，為Glassfibre Reinfored Polyester的簡稱。 采光板的主要成分是：上膜、強(qiáng)化聚酯、玻璃纖維。其中上膜要起到很好的抗紫外線抗靜電的作用，抗紫外線是為了保護(hù)采光板的聚酯不發(fā)黃老化，過早的喪失透光特性?？轨o電是為了保證表面的灰塵輕易被雨水沖走或被風(fēng)吹走，維持清潔美觀的表面。
玻璃纖維聚酯采光板（FRP）與玻璃卡布?。≒C）板之性能比較
1、FRP的基材為間苯二甲酸聚脂，PC板為普通聚碳酸脂；
2、FRP的熱膨脹系數(shù)為2.2×10-5 /cm/cm /℃，PC的熱膨脹系數(shù)為6.75×10-5/cm/cm/℃；FRP的熱膨脹系數(shù)接近鋼材的熱膨脹系數(shù)，由冷熱變化而引起的相對(duì)位移較少，不易因變形而漏水。而PC板引起的相對(duì)位移過大，引致螺釘孔周緣板撕裂、變形而漏水。
3、FPR的拉力強(qiáng)度較高，為94MPa能承受與鋼板相近的較高荷載，抗臺(tái)風(fēng)能力強(qiáng)。PC的拉力強(qiáng)度為60MPa，承受荷載的能力弱，與鋼板承受荷載的能力相差較大，抗臺(tái)風(fēng)能力弱。
4、FRP采用上下膜與玻纖加強(qiáng)的結(jié)構(gòu)形式，使其抗拉撕裂性能好。PC其分子結(jié)構(gòu)的特殊性致使PC板的抗撕裂性能差，容易被金屬的毛刺刺裂而漏水，所以不能只用螺釘來固定，以及與金屬直接接觸，固定PC板通常采用鋁壓板。
5、FRP的采光率為50% - 85%，PC的一般為85% - 91%。
6、FRP的熱傳導(dǎo)率為0.158w/m.k，PC的為0.166w/m.k，F(xiàn)RP的隔熱性能勝于PC板；
7、FRP的施工成本因板材的拉力強(qiáng)度、鋼度較高承受荷載能力強(qiáng)，能與鋼板配合在太跨度大檀距的鋼結(jié)構(gòu)屋面上使用。PC的板材鋼度差以及熱脹冷縮系數(shù)大，所以必須采用小分格小檀距或凸拱起弧增加強(qiáng)度，不適合用于大檀距的鋼結(jié)構(gòu)屋面上否則容易凹下面積水、漏水。
1, what is the light board lighting board's English name is Fibreglass Reinfored Polyester, translated into Chinese is glass fiber reinforced polyester (lighting plate), commonly known as fiberglass, used by its handwritten letter FRP for short. There is also a short name for GRP abroad called Glassfibre Reinfored Polyester. The main components of the daylighting board are: upper membrane, reinforced polyester and glass fiber. The upper film should play a very good anti - ultraviolet and anti - static effect. The anti - ultraviolet is to protect the polyester from the yellowing and aging, and the prematurely loss of light transmittance. Antistatic is to ensure that the dust on the surface is easily washed away by the rain or blown away by the wind, so as to maintain a clean and beautiful surface. The properties of glass fiber polyester lighting plate (FRP) and glass carbone (PC) board are compared 1, FRP substrate is polystyrene two formic acid polycarbonate, PC plate is ordinary polycarbonate; 2, FRP thermal expansion coefficient is 2.2 x 10-5 /cm/cm / C, the thermal expansion coefficient of PC is 6.75 x 10-5/cm/cm/. The thermal expansion coefficient of FRP is close to the thermal expansion of steel. The coefficient of expansion is less than the relative displacement caused by cold and heat, and it is not easy to leak due to deformation. The relative displacement caused by the PC plate is too large, which causes the edge plate of the screw hole to be torn, deformed and leaked. 3, the tensile strength of FPR is high, 94MPa can withstand high load similar to steel plate, and has strong typhoon resistance. The tensile strength of PC is 60MPa, the ability to bear load is weak, and the ability to withstand load is quite different from that of steel plate, and the ability to resist typhoon is weak. 4. FRP adopts upper and lower membrane and glass fiber reinforced structure to make it better in tensile and tear properties. The special molecular structure of PC leads to the poor tearing performance of the PC plate, which is easy to leak out by the burr of metal, so it can not be fixed by screw and direct contact with metal. The fixed PC plate usually uses aluminum plate. 5. The daylight rate of FRP is 50% - 85%, and PC is generally 85% - 91%. 6, the thermal conductivity of FRP is 0.158w/m.k, PC is 0.166w/m.k, and the insulation performance of FRP is better than that of PC plate; the construction cost of 7 and FRP is strongly loaded because of the tensile strength and steel degree of the plate, and can be used with steel plate in the steel structure roof with long span and large sandalwood distance. PC's plate steel degree difference and heat expansion and cold shrinkage coefficient are large, so the small sandalwood distance or convex arch arc must be adopted to increase the strength, not suitable for the steel structure roof of the big sandalwood distance, otherwise the water and water leakage are easily underneath.
