CarbonWrap Tape 900/300 is a unidirectional carbon tape on 24K yarn with a warp yarn count of 53 ± 1 per 10 cm, supplied in 50 m rolls 300 mm wide. Like the other tapes of the CarbonWrap external reinforcement system, it is cut to the design layout, impregnated with epoxy saturating resin and bonded to columns and beams; for a tape of this density the CarbonWrap Resin WS+ data sheet provides for its unfilled composition. The tensile strength of the fibre is more than 4.9 GPa, the modulus of elasticity more than 230 GPa.
| Manufacturer | CarbonWrap — OOO “Nanotekhnologicheskiy tsentr kompozitov”, Moscow |
|---|---|
| Type | composite strengthening |
| Use | columns and beams |
| Base | unidirectional tape of high-strength carbon fibres (fibre direction 0°); weft — hot-melt adhesive thread; warp — 24K carbon yarn |
| Packaging | roll of 50 m, width 300 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 tape (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 |
| Key properties | fibre direction 0°; warp yarn count 53 ± 1 yarns per 10 cm (24K); weft yarn count 10 ± 1 yarns per 10 cm; fibre tensile strength > 4.9 GPa; fibre tensile modulus > 230 GPa; fibre elongation at break > 1.5 % |
| Shelf life | 3 years from the date of manufacture; after that — use after repeat tests for compliance with the TU |
| Standards | TU 23.99.14-041-38276489-2017 (identical to 1916-041-38276489-2017) |
