Carbon-fiber-reinforced-polymers (CFRP) are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, and technical applications.

CFRP is used for reliable and high-performance structural strengthening systems. CFRP based solutions consist of CFRP plates and rods, plus structural epoxy resin-based adhesives. These systems are widely used for flexural strengthening of dynamically and statically loaded buildings and other structures such as bridges, beams, ceilings and walls, providing outstanding long-term durability in service.

We are following two methods for composite strengthening;

Plate bonding where the composite plates, which are usually carbon fibre reinforced, are manufactured off-site, and then bonded to the structure using epoxy adhesives and FRP wrap where the dry fibre fabric is either rolled into the wet resin on the structure's surface (dry lay) or the resin is applied to the fibre fabric which is then applied to the structure (wet lay).

Understandably quality control is easier with plates manufactured off-site but for strengthening around beams and columns the wrap system is the only solution. In both cases, there are strict quality control procedures to follow. HCR is qualified to design and install using both techniques and is approved by the leading material suppliers.
