Carbon Fiber Reinforcement and Repair Materials ②
Carbon Fiber-Reinforced Plastic Strips (e-Plate)
In the e-Plate strengthening construction method, a carbon fiber-reinforced plastic sheet that has been processed into a strip shape by a carbon fiber pultrusion method is bonded to an existing structure with a paste epoxy adhesive. Compared with conventional carbon fiber sheets, the amount of strengthening per unit width is significantly increased, so the attachment of a single e-Plate can provide a large strengthening effect. e-Plate is a very effective construction method for bending strengthening of deck slab and beams, which are necessary for changes to the purpose of a building and as measures for the increasing of bridge design load.
Features
- Improvement of Light Construction Workability and Reduction of Environmental Impact
Since e-Plate is simply bonded on the repair and strengthening points with a paste adhesive, it exhibits excellent workability. The amount of dust that is generated during construction is reduced because less surface treatment area and curing is required. - Stable Construction Quality and Improved Construction Efficiency
There are no concerns about impregnation defects, floating, blisters, and resin whitening, which are problems with the conventional carbon fiber sheet pasting method. Efficient construction is possible even in locations where pipes intersect or where repair space is limited. - Short Construction Period and Low Cost
One highly elastic e-Plate is equivalent to nine layers of highly elastic carbon fiber sheet *. Since e-Plate has excellent strength and rigidity, it is not necessary to bond several layers to the entire surface of the structure unlike carbon fiber sheets, and both the amount of work and the amount of strengthening materials are significantly reduced, which shortens the construction period and reduces costs.

Applications
Used for seismic strengthening and repair of deterioration in the fields of construction and civil engineering.

Carbon fiber-reinforced plastic rods (LEADLINETM)
LEADLINETM embedding method uses carbon fiber-reinforced plastic rods that are manufactured by processing carbon fiber into a rod shape by the pultrusion method. The rods are embedded in epoxy resin mortar or ultra-rapid hardening polymer cementitious mortar and bonded to an existing concrete deck slab of a road bridge to strengthen it.
Features
- Strengthening Member Protection When Renewing a Bridge Surface
Prevents damage to the strengthening members when renewing the asphalt layer or bridge waterproofing layer. - Shortened Construction Period
Compared with the carbon fiber construction method, the number of curing cycles can be reduced, so the construction period can be shortened. - Cost Reduction
LEADLINETM embedding method reduces construction costs by 85 to 95% compared to the carbon fiber sheet method. - Early Road Opening Possible
Since the curing time is fast, the LEADLINETM method is ideal for repairing and strengthening road bridges that need to be opened soon.
Applications
Used for seismic strengthening and repair of deterioration in the fields of construction and civil engineering.
Specifications
Construction
Two types of embedding methods are available: use of epoxy resin mortar and use of ultra-rapid hardening type polymer cementitious mortar for early opening of the bridge to traffic.
