产品介绍

​二级碳纤维布技术简介 (Grade II Carbon Fiber Cloth Technical Profile)​

​特点 (Features)​

二级碳纤维布以​​高强度碳纤维丝束​​(12K小丝束编织)为核心,抗拉强度≥3000 MPa,弹性模量≥200 GPa,伸长率≥1.5%,具备​​轻量化​​(200g/㎡厚度0.111mm,300g/㎡厚度0.167mm)和​​耐腐蚀性​​(耐酸碱/盐雾环境)。其表面呈​​灰白色或浅灰色​​,光泽度较低,丝束均匀但略粗糙,无断经/脱纬缺陷,且​​不可弯折​​(弯曲易断裂)。

​优点 (Advantages)​

  • ​经济高效​​:成本较一级布低20%-30%,适用于常规加固场景,性价比突出;
  • ​施工便捷​​:自重轻(仅为钢的1/4),单层粘贴即可提升承载力,无需复杂设备;
  • ​耐久性强​​:耐疲劳性优异(循环荷载下性能稳定),使用寿命超20年;
  • ​多功能适配​​:支持潮湿基面施工,兼容环氧树脂/聚氨酯等多种浸渍胶。

​用途 (Applications)​

  • ​建筑加固​​:混凝土梁/柱抗弯/抗剪加固(承载力提升25%-40%),砌体结构补强;
  • ​桥梁修复​​:桥墩/板梁裂缝修复(抗拉强度≥3000 MPa),抗震节点增强;
  • ​工业设备​​:储罐/管道防腐加固(耐化学腐蚀),重型机械底座防震;
  • ​体育器材​​:高尔夫球杆/赛艇轻量化部件(减重30%同时增加强度)。

​Grade II Carbon Fiber Cloth Technical Profile​

​Features​

Grade II carbon fiber cloth features ​​high-strength carbon fiber tow​​ (12K small tow woven), with tensile strength ≥3000 MPa, elastic modulus ≥200 GPa, and elongation ≥1.5%. It is ​​lightweight​​ (200g/㎡ thickness 0.111mm, 300g/㎡ 0.167mm) and ​​corrosion-resistant​​ (acid/alkali/salt fog resistance). The surface is ​​gray-white/light gray​​ with low gloss, uniform tow but slightly rough texture, free from broken warp/weft, and ​​non-bendable​​ (prone to fracture when bent).

​Advantages​

  • ​Cost-effective​​: 20%-30% lower cost than Grade I, ideal for routine reinforcement;
  • ​Easy installation​​: Lightweight (1/4 of steel), single-layer application for load enhancement;
  • ​Durability​​: Fatigue resistance under cyclic loads, service life >20 years;
  • ​Multi-functional​​: Wet-surface adhesion compatible with epoxy/polyurethane resins.

​Applications​

  • ​Building reinforcement​​: Concrete beam/column bending/shear strengthening (25%-40% load capacity increase), masonry repair;
  • ​Bridge restoration​​: Pier/slab crack repair (≥3000 MPa tensile strength), seismic node reinforcement;
  • ​Industrial equipment​​: Tank/pipeline anti-corrosion (chemical resistance), heavy machinery vibration damping;
  • ​Sports equipment​​: Golf clubs/sailboat components (30% weight reduction + strength gain).

 

​注​​:施工需严格遵循​​单向铺贴​​(纤维方向与受力方向一致),搭接长度≥100mm,配套使用​​浸渍胶​​(如B-7000型)并控制固化温度(15-35℃)。
