Unidirectional aramid fiber fabric is similar as carbon fiber fabric, also designed for structural strengthening, structural reinforcement, concrete repairs, construction retrofitting and construction leveling. It displays excellent dimensional stability with a slightly negative coefficient of thermal expansion (-2.4 x 10-6/℃). It’s resistant to chemicals with the exception of a few strong acids and alkalis. We can provide aramid fabric with different area weight, such as 280gsm, 415gsm, 623gsm,830gsm.
Advantages for FRP Structural Strengthening
- High strength to weight ratio
- Dimension stability, the glass fiber yarns are fixed tightly by the glued fiberglass yarn of low linear density
- Resistant to chemical corrosion, it’s resistant to most chemicals.
- Electrical insulation
- Low thermal conductivity
Applications of FRP Reinforcement
- Slab strengthening
- Bridge strengthening
- Tunnel strengthening
- dock strengthening
- Increase shear and flexural strength
- Increase load capacity
- Column wrap
