KYK MegaKarbon Wrap 300 K918
Carbon Fiber Structural Strengthening System
Product Description
KYK MegaKarbon Wrap 300 K918 is a carbon fiber reinforced polymer (CFRP) strengthening system consisting of unidirectional carbon fibers with very high tensile strength.
When combined with epoxy resin, it forms a rigid and high-performance composite system that significantly improves structural capacity.
Key features:
- Provides significant improvement in structural performance
- Lightweight and thin structure minimizes impact on architectural appearance
- High tensile strength enables effective reinforcement of structural elements
- Creates a durable composite system when applied with epoxy

Application Areas
KYK MegaKarbon Wrap 300 K918 is suitable for:
- Strengthening reinforced concrete beams, columns, and slabs
- Increasing the load capacity of precast and prestressed concrete elements
- Reinforcing wooden beams and masonry structural elements
- Repairing and strengthening structures damaged by earthquakes, impacts, or external factors
It is widely preferred in structural strengthening projects where high performance is required without adding significant weight to the building.
Product Advantages
- Extremely high fatigue resistance
- Low creep values
- Lightweight structure does not add significant load to the building
- Thin application thickness preserves architectural appearance
- Fast and practical installation
- Provides rigid structural behavior after epoxy bonding
- Long-lasting strengthening performance
Application Instructions
- The surface must be cleaned, sound, and prepared to provide a suitable bonding surface.
- Corners and edges should be rounded with a minimum 30 mm radius chamfer.
- The surface is primed with epoxy (MegaPro Epo Y501).
- The carbon fiber fabric is stretched and bonded in the fiber direction.
- Air bubbles must be removed using a roller.
- For multi-layer applications, a minimum 20 cm overlap should be provided.
- If plastering is required, graded sand should be applied while the epoxy is still wet to improve adhesion.
After application, the system must be protected against:
- Mechanical impacts
- Direct sunlight
- Fire exposure
Frequently Asked Questions
Does KYK MegaKarbon Wrap 300 K918 improve earthquake resistance?
Yes. It increases the load-bearing capacity and performance of structural elements such as beams, columns, and slabs.
Is it only suitable for reinforced concrete structures?
No. It can also be used for strengthening wooden and masonry structural elements.
How many layers should be applied?
The number of layers depends on structural analysis and project requirements. Multiple layers can be applied when necessary.
Can it be applied without epoxy?
No. KYK MegaKarbon Wrap 300 K918 is designed to work as a complete system together with MegaPro Epo Y501 epoxy resin.
Can plaster be applied over the system?
Yes. For proper adhesion, graded sand should be applied on the epoxy surface before curing, allowing plaster application afterward.
