Product Overview

SikaWrap-600 C is a heavy, unidirectional stitched carbon fibre fabric at 600 g/m2, used as externally bonded reinforcement in the Sika strengthening system. The 0-degree carbon tows are held by a light polyester stitch and binder rather than woven, keeping filaments straight for efficient load transfer once saturated with Sikadur epoxy by the wet lay-up method. The thick cured laminate delivers high tensile capacity per layer, suiting members that need significant flexural, shear or column-confinement reinforcement, seismic upgrades and service-life extension. It bonds to reinforced concrete, masonry, brickwork and timber with minimal added weight. The high areal weight reduces the number of plies on demanding strengthening schemes. Space Arc Engineering, an authorized Sika distributor in India, supplies SikaWrap-600 C with the matching Sikadur resins for strengthening contractors.

Features & Benefits

• Heavy 600 g/m2 stitched sheet provides high tensile capacity per single layer
• Stitched non-woven construction keeps carbon tows straight for efficient load transfer
• Carbon fibres rated about 3,800 N/mm2 tensile strength with a 242,000 N/mm2 modulus
• Optimised for wet lay-up with Sikadur-300 or Sikadur-330 saturating resin
• Reduces ply count on high-demand flexural, shear and confinement strengthening
• Corrosion-immune, low-weight reinforcement avoiding steel plate limitations
