Teknowrap 300 is a high tenacity unidirectional carbon fiber fabric used to reinforce structures.
Carbon fibers are one of the strongest materials in the world. Although carbon fibers are as thick as fabric, they are 14 times more tensile-resistant than STL steel and weigh about 1/5 that of steel. The advantage of using fibers is their elasticity, thanks to which they easily take the desired shape and harden when laminating with a special epoxy resin (Teknobond 300 Tix).

Applications:

  • To increase the durability and reliability of structures
  • For repairing damaged beams and arches
  • To increase the bearing capacity of structural elements
  • For the reconstruction of historical objects
  • To bring objects to the requirements of modern standards
  • When restoring bridges, viaducts, etc. when damaged due to corrosion
  • When correcting mistakes made during construction

Characteristics:

  • A more reliable method of strengthening structures compared to classical ones
  • Possibility to reinforce surfaces with non-standard geometry
  • Minimum weight and material thickness
  • High modulus of elasticity and high mechanical strength
  • Prevents surface damage from impact or explosions.

Surface quality, seams and joint surfaces must be dry and free from any kind of dust, dirt, loose and loose particles, grout residues, oil and grease. If present on weak concrete parts, they should be removed and the surface repaired with Teknogrout or Teknorep repair mortars.
The concrete base must be strong and have sufficient compressive strength (minimum 25 N/mm²) and a peel strength of at least 1.5 N/mm².
First you need to prepare and cut the carbon fibers of the required size. Then prepare the Teknobond 300 Tix epoxy adhesive and evenly apply it to the concrete surface with a spatula, then press the Teknowrap 300 carbon fiber cloth to the surface. Remains of glue should be removed immediately with a plastic roller with small teeth.
After the completion of the laying of carbon fibers, it is recommended to sprinkle with a thin layer of sand and apply plaster, because carbon fibers do not burn, however, the epoxy grout can catch fire at a certain temperature.
Notes:

  • A structural reinforcement project should be designed and executed under the supervision of an experienced civil engineer.
  • Clean tools and equipment with water immediately after use. Hardened material can only be removed mechanically.
  • The product may cause irritation if it comes into contact with the skin. Work clothes, protective gloves, mask and goggles must be used. Before starting work, you can apply a protective cream on your hands. In case of contact with eyes, immediately rinse eyes with warm water and seek medical advice.
