SikaWrap-451 C IN
India-grade 450 g/m2 unidirectional carbon fabric for high-load dry lay-up strengthening
Product Overview
SikaWrap-451 C IN is an India-grade, unidirectional woven carbon fibre fabric at 450 g/m2, engineered for the Sika dry lay-up strengthening system. Its warp uses selected high-strength carbon filaments at 0 degrees, with a heat-set glass weft holding the heavy sheet square for accurate placement. Applied with Sikadur-330 IN as primer and laminating resin, it cures into a thick, high-capacity carbon laminate that raises axial, flexural and shear strength, confines columns and corrects structural defects. The high areal weight delivers maximum reinforcement per layer, making it efficient for heavily loaded members where ply count must be minimised. Locally optimised packaging suits Indian site logistics. Space Arc Engineering, an authorized Sika distributor, supplies SikaWrap-451 C IN with Sikadur-330 IN to strengthening specialists across India.
Features & Benefits
- Heavy 450 g/m2 sheet gives maximum reinforcement per layer, minimising ply count
- High-strength carbon fibres rated about 4,900 N/mm2 with a 250,000 N/mm2 modulus
- Thick 0.250 mm laminate per layer for high-load flexural and confinement work
- Single-resin dry system with Sikadur-330 IN for efficient site application
- Heat-set glass weft keeps the dense fabric aligned and crease-free
- Non-corroding, low-weight upgrade compared with bonded steel plates
Technical Highlights
| Coverage | Sikadur-330 IN consumption is about 0.8 to 1.2 kg/m2 for the first layer and 0.5 to 0.8 kg/m2 for each additional layer. |
| Strength | Carbon fibre tensile strength near 4,900 N/mm2 with a tensile modulus of about 250,000 N/mm2 and elongation at break around 2.1%. |
| Performance | Builds a thick 0.250 mm structural laminate per layer for high tensile capacity; use design values from the TDS. |
| Application Conditions | Apply to a clean, laitance-free, open-textured substrate of at least 1.0 N/mm2 tensile strength; follow Sikadur-330 IN temperature limits, refer to TDS. |
| Packaging | Supplied as one roll per carton, 500 mm wide and 50 m or more in length. |
Applications
- Maximum flexural and shear strengthening of heavily loaded bridge and flyover girders
- Seismic confinement of large-section building and infrastructure columns
- Strengthening industrial transfer beams and structures under major load increases
- Correcting significantly under-reinforced members in commercial construction
- Heavy-duty rehabilitation of distressed columns and beams in residential towers

Frequently Asked Questions
What is SikaWrap-451 C IN best suited for?
It is the heaviest India-grade woven carbon fabric in the range at 450 g/m2, forming a thick 0.250 mm laminate per layer. It is ideal for heavily loaded members where high reinforcement is needed with the fewest possible plies.
How does SikaWrap-451 C IN compare to SikaWrap-301 C IN?
Both are India-grade high-strength carbon fabrics for dry lay-up, but SikaWrap-451 C IN is heavier (450 vs 300 g/m2) with a thicker laminate, giving more reinforcement per layer for higher-load applications.
Which resin is used with SikaWrap-451 C IN?
It is applied by the dry lay-up method using Sikadur-330 IN, which acts as both the priming coat and the impregnating laminating resin that cures to form the structural carbon laminate.
What does SikaWrap-451 C IN strengthen?
It strengthens reinforced concrete, masonry, brickwork and timber – increasing axial, flexural and shear capacity, confining columns and improving seismic performance for buildings, bridges and industrial structures.
