玻璃钢复合资料用于野战工事的优点

The advantages of FRP composite materials used in the fieldwork

玻璃钢（FRP）亦称作GRP，即纤维强化塑料，是一种树脂基复合资料。普通指用玻璃纤维加强不饱和聚脂、环氧树脂与酚醛树脂基体。

Glass fiber reinforced plastic (FRP) is also called GRP, the fiber reinforced plastic, is a kind of resin matrix composite materials. Normal refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix.

玻璃钢是目前世界上产量最大、用处最广的复合资料，玻璃钢工业是往常最抢手的工业之一，它以其优秀的性能在各个范畴得到普遍

的应用，如:储罐、管道、建筑、交通运输、运动与游乐器材、船艇等方面都得到普遍应用。在野战筑城中，用玻璃钢做的各种工事在战争中起到了重要作用，在将来高技术战争中将发挥越来越大的作用。

FRP production in the world is the largest, the most widely use of composite materials, glass fiber reinforced plastic industry is always one of the most popular industry, with its excellent performance has widespread application in various categories, such as: storage tank, pipe, construction, transportation, sports and recreation equipment, boats, etc have been widely used. In field fortification, made of glass fiber reinforced plastic works played an important role in the war, in the future high technology war will play a growing role.

FRP(玻璃纤维加强塑料,简称玻璃钢)是以合成树脂为基体、玻璃纤维(织物)为加强资料的复合资料。具有许多优秀的特性:

FRP (glass fiber reinforced plastics, glass fiber reinforced plastic) is a synthetic resin as the matrix and glass fiber composite material (fabric) in order to strengthen the information. With many excellent properties:

轻质高强，比重114-2.0,约为钢的1/5,铝的1/2,其比强度和比模量超越钢和铝合金；冲击韧性好，适合于接受动荷载及爆炸冲击荷载；抗老化及阻燃性好(玻璃钢中参加阻燃剂或采用阻燃树脂再参加阻燃剂，可满足防火请求)；其夹层构造隔热保温性能好，导热系数和热应力小(分别为钢管的0.14%和1/11)；电绝缘性能好，可平安地应用于输电、电信密集区；设计和可施工性好，装置快捷便当、平安，简直不动火。

Light weight, high strength, the proportion of 114-2.0, which is about 1/5 of the steel, aluminum 1/2, its than strength and modulus of steel and aluminum alloy; Good impact toughness, suitable for dynamic loads and the explosion impact load; Anti-aging and good flame retardancy (FRP flame retardants or using flame retardant resin again to participate in the flame retardants, can meet the fire protection request); The sandwich construction heat insulation performance is good, small coefficient of thermal conductivity and thermal stress (0.14% of the steel tube and 1/11, respectively); Electric insulation performance is good, can be safely used in power transmission and telecommunication concentration areas; Design and construction, installation quick lunch, peace, don't hot.

因而，FRP极适合于制造野战工程中的快速装配式预制构件，在防护工程野战工事的应用上越来越遭到注重。

Therefore, FRP pole is suitable for manufacturing prefabricated prefabricated quickly in field engineering, application in protective engineering fieldwork on more and more notice.

目前所用的玻璃纤维，其应力应变曲线如图所示，从图中能够看出，单纤维受力不分歧，股纱毁坏呈现一个逐渐断裂的过程。最常用的玻璃纤维布有平纹、斜纹和缎纹等除渣机，其中斜纹中的2/2斜纹布铺覆性较好，较适用于制造玻璃钢工事构件。合成树脂在玻璃钢中的作用，是将分散的玻璃纤维或其织物粘结成一个整体，同时已固化的树脂又是玻璃钢的一组分，其性能将直接影响玻璃钢的力学、耐温、耐腐蚀和介电等性能，此树脂的选择也十分重要。用于玻璃钢的常用树脂大局部为热固性树脂，主要有不饱和聚酯、环氧、酚醛以及改性的聚酯和环氧。玻璃钢工事构造设计时，既要满足构件规范化的请求，又要满足荷载请求，同时尽量使生存空间有温馨感紫叶李。其构造方式根本上有两类：筒壳和球壳。关于单一玻璃钢资料，壁厚度通常取6-10mm，关于夹层资料，普通取蒙皮厚2-4mm，夹芯厚40-60mm。
