纤维钢筋

以高强玻璃纤维为增强材料，以合成树脂为基体材料，并掺入适量辅助剂复合而成的复合材料，称为玻璃纤维增强塑料（英文缩写：FRP）俗称玻璃钢。玻璃钢筋材是一种粗糙表面螺纹式杆体，其比重一般在1.5-1.9（g/cm³）之间。

产品特点
比强度高：抗拉强度优于普通钢材，高于同规格钢筋的20%，而且抗疲劳性好；
质量轻：仅为同体积钢筋的1/4；
耐腐蚀性强：可抵抗氯离子和低PH值溶液的侵蚀，尤其是抗碳化合物和氯化合物的腐蚀性更强；
材料结合力强：热膨胀系数与钢材相比更接近水泥，因此FRP筋材与混凝土结合握裹力更强；
可设计性强：弹性模量稳定。热应力下尺寸稳定，折弯等形状可任意热成形；安全性能好，不导热、不导电、阻燃抗静电，通过配方改变与金属碰撞不会产生火花；
透磁波性能强：FRP筋材是一种非磁性材料，在非磁性或电磁性的混凝土构件中不用做脱磁处理；
施工方便：可按用户要求生产各种不同截面和长度的标准及非标准件，现场绑扎可用非金属拉紧带，操作简单。混凝土结构增强（需较大安全储备量的部位）需要防结冰液体中的混凝土结构；海水、淡水等腐蚀介质环境的混凝土结构；非承载的混凝土结构，需要脱磁的特殊工程领域。
应用范围：该产品可广泛用于以下领域：混凝土结构增强（需较大安全储备量的部位）需要防结冰液体中的混凝土结构；海水、淡水等腐蚀介质环境的混凝土结构；隧道、钻探勘探工程中短期加固的混凝土结构；对非承载的混凝土结构；对热传导敏感的混凝土结构。如：水利、污水处理系统混凝土结构工程、化工厂、大体积浇拉模板、水中桩柱、交通、煤矿、地下建筑、隧道遂洞工程、港口码头等工程领域

FRP composite rebars are by combining the pultrusion process and an inline winding and coating process for the outside sand surface.
The FRP composite rebar is made from high strength glass fibers along with an extremely durable vinyl ester resin.
The glass fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments.
For improved stiffness and mechanical properties a carbon/vinyl ester product is available.
FRP rebar significantly improves the longevity of civil engineering structures where corrosion is a major factor.

 
The main benefits of FRP composite rebars when compared to steel rebar:
CORROSION RESISTANCE - will not rust, and are impervious to the action of salt ions, chemicals, and the alkalinity inherent in concrete.
LIGHTWEIGHT - weigh approximately one-quarter the weight of an equivalent size steel bar, offering significant savings in both placement and use.
ELECTROMAGNETIC NEUTRALITY - contain no metal, and will not interfere with the operation of sensitive electronic devices such as medical MRI units or electronic testing devices.
THERMAL INSULATOR – highly efficient in resisting heat transfer, such as from building exteriors to interiors.
Utilizing inherent features / benefits, FRP composite rebar has cost effective application as a concrete reinforcing bar in the following markets when analyzed on a life-cycle cost basis:
Reinforced Concrete Exposed to Deicing Salts: Parking structures; bridge decks; Jersey barriers; parapets; curbs; retaining walls and foundations; roads and slabs on grade.
Structures Built in or Close to Sea water: Quays; retaining wall; piers; jetties; caissons; decks; piles; bulkheads; floating structures; canals; roads and buildings; offshore platforms; swimming pools and aquariums.
Applications Subjected to Other Corrosi
