SikaWrap-301 C IN
India-grade 300 g/m2 unidirectional carbon fabric for dry lay-up strengthening
Product Overview
SikaWrap-301 C IN is an India-grade, unidirectional woven carbon fibre fabric at 300 g/m2, built for the Sika dry lay-up strengthening system. Its warp uses selected high-strength carbon filaments oriented at 0 degrees, while a heat-set glass weft keeps the heavier sheet dimensionally stable for accurate placement. Impregnated with Sikadur-330 IN as primer and laminating resin, it cures into a robust carbon laminate that increases axial, flexural and shear capacity, confines columns and corrects design or construction defects. The higher areal weight provides more reinforcement per layer than 230-class fabrics, reducing the number of plies on demanding members. Space Arc Engineering, an authorized Sika distributor, supplies SikaWrap-301 C IN together with Sikadur-330 IN to strengthening specialists across India.
Features & Benefits
- Heavier 300 g/m2 sheet delivers more reinforcement per layer, often cutting ply count
- High-strength carbon fibres rated about 4,900 N/mm2 with a 250,000 N/mm2 modulus
- Heat-set glass weft keeps the dense fabric straight and easy to align
- Single-resin dry system with Sikadur-330 IN streamlines application
- India-grade specification and packaging tuned for local site needs
- Lightweight, non-corroding upgrade compared with bonded steel plate
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 0.166 mm structural laminate per layer for high tensile reinforcement; 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
- High-demand flexural and shear strengthening of bridge and flyover girders
- Seismic confinement of heavily loaded building columns
- Strengthening industrial beams and transfer girders under increased loads
- Upgrading defective or under-reinforced members in commercial buildings
- Wrapping residential columns and heavy slabs during major rehabilitation

Frequently Asked Questions
How is SikaWrap-301 C IN different from SikaWrap-231 C IN?
Both are India-grade high-strength carbon fabrics, but SikaWrap-301 C IN is heavier at 300 g/m2 with a thicker 0.166 mm laminate per layer, providing more reinforcement per ply for higher-load applications.
What resin is used with SikaWrap-301 C IN?
It is applied by the dry lay-up method using Sikadur-330 IN, which serves as both the priming coat and the impregnating laminating resin that cures to form the structural carbon laminate.
What is the consumption of resin for SikaWrap-301 C IN?
Sikadur-330 IN is typically used at about 0.8 to 1.2 kg/m2 for the first layer and 0.5 to 0.8 kg/m2 for each following layer, varying with substrate profile. Confirm in the current TDS.
What structures can SikaWrap-301 C IN strengthen?
It strengthens reinforced concrete, masonry, brickwork and timber – boosting axial, flexural and shear capacity, confining columns and improving seismic performance for buildings, bridges and industrial structures.
