FRP Wrap Materials

Carbon and Glass Fibre Reinforced Polymers (FRP), also called composite materials, are popularly used in structural strengthening for steel, wood, concrete, seaport and aerospace applications because of their cost-effectiveness and superior performance in high strength, light weight, corrosion resistance, bomb blast and earthquake protections.

American Society for Testing and Materials (ASTM), American Concrete Institute (ACI), British and European Standards established design and test criteria for metal and concrete structural repair for decades.

The design codes are BS8110, EN1504, ACI440 and composite laminate analysis.

Wrapping Process, Qualification Tests and Long-term Structural Health Monitoring (SHM) are as follows:

  • Surface preparation
  • Installation of FRP composite wrap
  • Quality control
  • Surface finishing
  • Pull-out test, scaling-down load test and NDT test
  • Full-scale load test, aging test, corrosion monitoring, fibre optic sensing (FOS) SHM test
