SikaWrap® Hex-117 C

Carbon fiber fabric for structural strengthening

SikaWrap Hex 117C is a unidirectional carbon fiber fabric. Material is field laminated using either Sikadur 300/Hex 300, Sikadur 301 or Sikadur 330 epoxy to form a carbon fiber reinforced polymer (CFRP) used to strengthen structural elements.

  • Lightweight fabric ideal for confined spaces
  • Used for shear, confinement or flexural strengthening
  • Flexible, can be wrapped around complex shapes
  • High strength
  • Non-corrosive
  • Alkali resistant
  • Low aesthetic impact

Application

Application steps

SUBSTRATE PREPARATION

Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials and other bond inhibiting materials from the surface. Consult Sikadur® Hex 300 and Sikadur® 330 technical data sheets for additional information on surface preparation. Existing uneven surfaces must be filled with an appropriate repair mortar. The adhesive strength of the concrete must be verified after surface preparation by random pull-off testing (ACI 503R) at the discretion of the engineer. Minimum tensile strength, 200 psi (1.4 MPa) with concrete substrate failure.

  

Preparation Work: Concrete - Blast clean, shotblast or use other approved mechanical means to provide an open roughened texture. In certain applications and at the engineer’s discretion, the intimate contact between the substrate and the fabric may be determined to be non-critical. In these cases, a thorough cleaning of the substrate using low pressure sand or water blasting is sufficient.

  

Mixing

Consult Sikadur® Hex 300 or Sikadur® 330 technical data sheet for information on epoxy resin.
