FRP Fiber-reinforced polymer

FRP materials, or fiber-reinforced polymers, are composite materials consisting of a polymer matrix reinforced with fibers. They are used in structural rehabilitation to bolster load-bearing capacity due to planned increases in live loads or the removal of load-bearing elements.

The application of FRP strengthening technology is recommended for:

  • Strengthening masonry arches and vaults against static and seismic forces with upper-side lining.
  • Wrapping externally overloaded compression or bending elements such as columns, beams, pipelines, and chimneys.
  • Rehabilitating structures damaged by impacts, like overpasses from oversized vehicles.

Advantages of using FRP systems include:

  • Corrosion resistance High tensile strength
  • Excellent performance under dynamic loading
  • Resistance to most alkalis and acids
  • Vibration damping capability
  • Extremely favorable strength-to-weight ratio (40-50 times higher than steel)

FRP's benefits as a construction material include its high strength-to-weight ratio, specific stiffness, and chemical adhesion. It also reduces labor and equipment costs, minimizes installation time, and disrupts service less during application. However, challenges remain, such as the lack of universal design codes and standards, particularly in upgrading existing structures. Additionally, there's ongoing research needed into the long-term environmental impact of resin use at higher volumes seen in construction compared to aerospace or automotive industries. Our Solidian Wrap is a prime example of such an innovative composite. This non-corrosive, high-strength, lightweight carbon product enhances flexibility without compromising strength, significantly increasing the stiffness and ductility of structural elements.
