Product Description
Chelfix Wrap 301 is a dry fabric constructed of very high strength, aerospace grade carbon fibers.
Areas of Usage
* Load Increase:
- Increase in loads in commercial buildings.
- Increase in traffic weight and volume on bridges.
- Installation of heavy equipment in industrial facilities.
- Increase of vibration in structures.
*Improve Structural Condition:
- Reduce deformations.
- Reduce stresses in existing structural elements.
- Limit or arrest crack propagation.
* Seismic Retrofitting:
- Columns wrapping reinforcement for improving ductility and shear strength.
Masonry walls reinforcement for improving out-of-plane bending and in-plane shear strengths.
- Beam and slab reinforcement.
* Change Structural System (Structural Alterations):
- Removal of walls or columns.
- Removal of slab sections for openings.
* Aging and Damaged Structures:
- Aging of old deteriorated construction materials.
- Corrosion of steel bars in concrete.
- Vehicles collusion impact on structures (impact damage).
* Design or Construction Errors:
- Lack of adequate well-detailed reinforcing bars.
- Inadequate member cross section.
- Substandard concrete material strength.
Advantages
- High strength to weight ratio. Can add significant strength to a structure without adding significant dead load.
- When it's wrapped around the stirrup tightening areas of the column, it acts an additional stirrup.
- Increase the cutting capacity of the column.
- Increases vertical transport capacity when wrapped around circular columns.
- It prevents the wall from being scattered in any kind of wall, in the face of impact and explosion.
- When the column is completely wrapped, the stretchability of the column increases in great extent, so there is no breakage in the columns even at larger oscillations.
- The most obvious advantage of the carbon fiber repair method is that it can achieve a multiple of the robustness achieved with conventional methods, even though it adds only a few millimeters of thickness.
- Stronger than steel but much more lightweight, no corrosion problem. it can easily take shape.
