What is FRP? Composite Strengthening Systems™ Overview

Fiber-reinforced polymer (FRP) systems are simply defined as high-strength and lightweight reinforcements created by combining carbon (CFRP) or E-glass fibers with a polymer material. Traditionally, FRP has been used in the civil, aerospace, and automotive industries for applications requiring high strength-to-weight ratios and rigidity.

More recently, the performance characteristics of FRP strengthening have become increasingly popular in construction and retrofit applications, specifically in aging, damaged or overloaded concrete structures.

FRP strengthening solutions are engineered, specified and installed to solve a host of structural deficiencies or demands in existing structures:

  • Durability problems due to poor or inappropriate construction materials
  • Inadequate design or construction
  • Increased loading requirements due to code or use changes
  • Increased life-span requirements made on aging infrastructure
  • Exceptional or accidental loading
  • Seismic retrofit
  • Blast mitigation

Owners of structures such as warehouses and parking garages can generate more revenue from existing assets by making previously un-rentable space rentable.

FRP solutions are normally designed by a structural engineer. Materials are supplied by a manufacturer such as Simpson Strong-Tie. The installation is performed by a field-trained contractor.

Simpson Strong-Tie Composite Strengthening Systems (CSS) provide efficient fiber reinforced polymer (FRP) solutions for the structural reinforcement and strengthening of concrete, masonry and timber structures in need of repair or upgrade.
