USE OF CARBON FIBRE REINFORCED POLYMER FOR STRUCTURAL STRENGTHENING IS A "GAME CHANGER"
The strength of most elements in a concrete structure can be significantly improved by using carbon fibre reinforced polymer (CFRP) plates, rods, fabric and wrap for increasing flexural, compression and shear/tensile load capacity of elements such as beams, columns, suspended floors, penetrations and decks.
Metal elements can also be strengthened in any load-bearing structure.
FCS Concrete Repairs uses Sika Structural Strengthening Systems for their proven performance and durability.
Carbon Fibre strengthening can successfully extend the functional service life of a building or civil engineering structure and accommodate loading changes when function changes impose increasing demands on the structure.

The Question: Which aircraft has the highest weight ratio for CFRP?
Airbus A350 XWB vs Boeing 787 Dreamliner
The Airbus A350 XWB is built of 52% Carbon Fibre Reinforced Polymer (CFRP) including wing spars and fuselage components, overtaking the Boeing 787 Dreamliner, for the aircraft with the highest weight ratio for CFRP, which was held at 50%.
This was one of the first commercial aircraft to have the wing spars made from composites.
The Airbus A380 was one of the first commercial airliner to have a central wing box made of CFRP; it is the first to have a smoothly contoured wing cross section instead of the wings being partitioned span-wise into sections. This flowing...

Application of FRP Composites in Strengthening the Reinforced Concrete Headstock of a Bridge Structure
Worldwide interest is being generated in the use of fibre-reinforced polymer composites FRP in the rehabilitation of aged or damaged reinforced concrete structures. As a replacement for the traditional steel plates or external posttensioning in strengthening applications, various types of FRP plates, with their high strength-to-weight ratio and good resistance to corrosion, represent a class of ideal material in externally retrofitting.
This paper describes a solution proposed to strengthen the damaged reinforced concrete headstock of the Tenthill Creeks Bridge, Queensland, Australia, using FRP composites.

THE EGYPTIAN MUSEUM
The famous Egyptian Museum which houses priceless Egyptian antiquities features a series of steel reinforced concrete arches which have suffered considerable deterioration through corrosion during the past century since it was opened.
The spans are approximately 17 metres across and they were successfully strengthened using Carbon Fibre Reinforced Polymer.
The process was to remediate the existing steel reinforcement prior to applying the CFRP to the underside of the arches and to the faces. Anchors were also fixed during the repair process to anchor the flexural strips and to increase the shear strength.

Sika CarboDur® - FLEXURAL STRENGTHENING
Sika CarboDur® is a carbon fiber reinforced polymer used to allow concrete, beams and floors to carry much higher loads. Sika CarboDur® makes it easy to strengthen concrete beams and floors to make new design loadings or take heavier loadings. It`s cost effective and because it can be installed so quickly, disruption is minimal. See how Sika Carbodur fibre reinforced polymer plates (FRP) allow concrete beams and floors to carry much higher loads. CarboDur® another smart, innovative strengthening solution from Sika.
