For structures of complex shape and work in confined conditions the manufacturer offers CarbonWrap Fabric 450/1200 — a bidirectional 2×2 twill of 12K carbon yarn with fibres at 0° and 90°. It is part of the CarbonWrap external reinforcement system and, after impregnation with CarbonWrap Resin epoxy saturating resin, is used for restoration, repair, strengthening and seismic retrofitting of reinforced concrete, concrete, masonry, steel and timber elements. The fibre strength is at least 4.9 GPa, the elongation at break 1.8 %.
| Manufacturer | CarbonWrap — OOO “Nanotekhnologicheskiy tsentr kompozitov”, Moscow |
|---|---|
| Type | composite strengthening |
| Use | columns and beams |
| Base | bidirectional carbon fabric of high-strength carbon fibres, fibre direction 0°/90°, 2×2 twill weave; warp and weft — 12K carbon yarn |
| Packaging | rolls of 50 and 100 linear m, width 1200 ± 10 mm, 1 roll per cardboard box; sold by the roll |
| Application method | cutting to the design bonding layout on a clean, flat surface covered with protective film; cut with scissors or a sharp knife, wearing protective gloves; keep free of sand, dust, water, oils and solvents; do not fold the fabric (the fibres break at the fold), it may be rolled up for transport; prevent splitting into strands and damage to the fibre; impregnation and bonding with CarbonWrap Resin epoxy saturating resin |
