Thanks to deep expertise in pultrusion, Epsilon Composite delivers the most efficient flat carbon reinforcements on the market
- Volume fraction of fiber (Vf) of 70%,
- Peel-ply strip on both sides for optimal bonding,
- Perfect fiber alignment.
Reinforcement of the Westgate Bridge in Melbourne: an unparalleled benchmark
In 2010, Epsilon Composite supplied Carbolam® carbon plates for what would become the largest bridge reinforcement project in the world:
- 100 km of Carbolam® provided for the addition of an extra traffic lane,
- Traffic kept flowing during the work thanks to the ease of implementation of the carbon solution.
- Read the article in Composites World on the topic.
- Read the case study on the project.
Carboglulam: evolution of Carbolam® for the manufacture of large carbon beams
Using patented technology, Carboglulam® beams consist of a successive assembly of carbon plates and are custom-made (length, width, thickness) to meet specific stiffness requirements, where Carbolam® is not sufficient anymore:
- Tensile modulus (E) from 160 to 450 GPa
- Shape: rectangular or bevelled. Can also be curved.
- Length up to 10 metres (more on request)
Simulation of use for our reinforcement solutions:
Reinforcement around holes
- Carbolam® plates externally bonded
- Or Near Surface Mounted reinforcements
Pre-stressed reinforcements
Pre-stressed CFRP plates or rods can be used on a wall, a slab or bridge to increase resistance and decrease deformation
Contact
Seismic reinforcement
«Cross of Saint André» pattern, from either ;
- Carbolam® plates
- Carboglulam® pre-assembled plates
Reinforcement around holes
- Carbolam® plates externally bonded
- Or Near Surface mounted reinforcements.
Ceiling or slab reinforcement
Carbolam® plates externally bonded to reinforce the ceiling of a RC structure (building, parking, bridge…)
Contact
Beam reinforcement
3 different levels of beam reinforcement are possible:
- Level 1: Carbolam® plates can be used to reinforce a beam
- Level 2: Epsilon fabrics can be used for additional shear resistance
- Level 3 : Carbocore® CFRP anchors can be used for higher loads transmission
Pillar reinforcement
3 different levels of pillar reinforcement are possible, to replace or reinforce corroded irons, or to sustain higher loads:
- Level 1: Epsilon fabrics can be used to contain the pillar
- Level 2: Carbolam® plates can be used in addition to fabrics as flexural / buckling reinforcement, either externally bonded or Near Surface Mounted
- Level 3: Carbocore® can be used for higher loads transmission on bottom and top of pillars
Door or window lintel reinforcement
When creating an opening in a wall (door or window), 3 different levels of reinforcement are possible:
- Level 1: Carbolam® plates can be used on the lintel
- Level 2: Epsilon fabrics can be used for additional shear resistance
- Level 3: Carbocore® CFRP anchors can be used for higher loads transmission
Near Surface Mounted reinforcement
Carbolam®, Carborod®, Carbosquare® or Carbospire® invisible reinforcements for slabs, walls or pillars.
Near Surface Mounted (NSM) reinforcement are an effective way to reinforce a RC structure with minimum efforts and visual impact, or in case of limited space.
It also minimize the risk of debonding between CFRP & concrete
