GFRP Reinforcement and Repair Material Advantages

• Composite materials have high specific strength and specific modulus;
• Composite materials have strong designability;
• Composite materials have a variety of molding processes, which facilitate reinforcement over large areas or for structures that are more complex;
• The repair process does not require shutdown, has a short repair time, low cost, and requires simple equipment for on-site repair.

Commonly used composite materials for pipeline defect repair include Glass Fiber Reinforced Plastic (GFRP), Carbon Fiber Reinforced Plastic (CFRP), and Aramid Fiber Reinforced Plastic (AFRP). Glass fiber is a good insulating material and will not undergo electrochemical corrosion with the pipeline, hence, glass fiber reinforcement technology has been widely applied in pipelines.

GFRP repair technology can be divided into two processes: wet wrapping and full cure.
