Kevlar纤维复合材料在土木工程结构加固中的应用

Application of Kevlar Composite Material in Reinforcement of Civil Engineering

简要介绍了用于纤维增强复合材料(FRP)的碳纤维(CF)、对位芳纶(AF)、玻璃纤维(GF)、玄武岩纤维(BF)的特性。用图表介绍了Kevlar49布的规格、技术参数、特点、应用及加固工艺,并对FRP市场需求作了详细分析。结果表明:Kevlar49布具有较强的市场竞争力;中国土木工程结构加固的潜在市场非常巨大,将为高性能纤维及其FRP生产商带来无限商机。

The carbon fiber, aramid fiber, glass fiber and basalt fiber used for fiber reinforced plastics （FRP） are briefly introduced. The specifications, parameters, features, applications and consolidated pro- cess of Kevlar 49 cloth are described in tables and figures, and the market of FRP is analyzed in detail. The results show that Kevlar 49 cloth possesses a stronger competitive power in the market. China has a big potential market in civil construction consolidation and it will bring business opportunities to hi-tech fiber and FRP manufacture.
