Sika SikaWrap Hex 103C 25"x50' Roll 104sf 103837
SikaWrap Hex-103 C is a high-strength unidirectional carbon fiber fabric in a 25 in x 50 ft roll for structural concrete strengthening. It field-laminates with Sikadur-300 or Hex-300 epoxy for shear, confinement, seismic, and flexural CFRP work.
- Unidirectional carbon fiber fabric, 18 oz per sq yd
- Shear, confinement, seismic, and flexural strengthening
- ICC ESR-3288 evaluated FRP system
SikaWrap Hex-103 C
SikaWrap Hex-103 C is a high-strength unidirectional carbon fiber fabric field-laminated with Sikadur-300 / Sikadur Hex-300 to form a CFRP strengthening system. This 25 in x 50 ft roll is the same fabric as the 25 in x 300 ft roll. Area density is 18 oz per sq yd with a 0.04 in nominal ply, dry fiber tensile strength is 550 ksi, and the system is covered under ICC ESR-3288.

Frequently Asked Questions
What strengthening work is SikaWrap Hex-103 C used for?
Shear, confinement, seismic, and flexural strengthening of structural concrete. Typical drivers include load increases, seismic upgrades, damage repair, and design corrections.
What fiber construction does SikaWrap Hex-103 C use?
Unidirectional (0 deg) carbon fiber at 18 oz per sq yd with a 0.04 in nominal ply thickness.
What epoxy laminates SikaWrap Hex-103 C?
Sikadur-300 / Sikadur Hex-300 epoxy forms the CFRP laminate in the field. Follow the current resin data sheets for prep and wet-out.
What ICC evaluation covers SikaWrap Hex-103 C?
The system is independently tested to ICC AC125 and referenced under evaluation service report ICC ESR-3288.
What dry-fiber tensile strength does SikaWrap Hex-103 C have?
Published dry fiber tensile strength is 550 ksi, with tensile modulus 34 msi and elongation at break 1.5%.
What design guides apply to SikaWrap Hex-103 C?
Systems follow ACI 440 guides for externally bonded FRP on concrete and unreinforced masonry, plus IBC/IRC compliance noted on the sheet.
