Carbon fibre solutions for the construction and reinforcement of civil engineering structures and infrastructures (bridges, silos, buildings, etc.)
Use of composites for the reinforcement of civil structures
Since the 1990s, thousands of structures around the world have been repaired and reinforced with carbon laminates (usually plates or rods), and installed on bridges, car parks, buildings, industrial installations, silos, dykes, chimneys, etc.
Today, the use of pultruded composite carbon fibre reinforcements on concrete structures is a recognised and effective reinforcement method, proving to be much more efficient than the use of steel plates (which are heavy and vulnerable to corrosion).
- The repair or strengthening of concrete elements that have deteriorated over time
- The reinforcement of undersized beams and floors (better flexion resistance).
- The reinforcement of load-bearing elements of buildings undergoing superimposed loads.
- Anti-seismic compliance of structures located in high-risk areas to be ensured.
Examples of structures such as this: bridges, plates, slabs, vaults and containers, or structures with a high radius of curvature.
A common solution for reinforcing concrete structures is the application of carbon fibre textiles, which does not provide optimal mechanical properties. In the 1990s, CARBOLAM® was developed using Epsilon Composite’s unique technology and expertise in carbon pultrusion and epoxy matrices.
CARBOLAM® are flat laminates made from unidirectional carbon fibre combined with a polymer resin and protected by a peel-ply strip on each face, thus ensuring that the yield of the fibres used is maximised.
The use of different carbon fibres (high strength, high modulus, and very high modulus) makes it possible to offer different grades of CARBOLAM® depending on the required stiffness.
CARBORODs are circular pultruded rods that operate on the same principle as CARBOLAMs.
With a variable diameter (between 3 and 20mm), they can also integrate a peel-ply strip to ensure better anchoring and to protect the rod until it is installed.
Adhesive bonding assembly of CARBOLAM plates makes it possible to obtain CARBOGLULAM beams, following a process patented by Epsilon Composite.
These beams make it possible to produce thick reinforcements, with a variable thickness over the length and by integrating radii of curvature if necessary.
