Technical Data Sheet Carbon Fiber Reinforcing Grids for Concrete Structures DESCRIPTION C-GRID® C50 – ø x 2.7 is one of the C50 Series of high strength carbon fiber/epoxy grids for reinforcing concrete structures. Large high strength carbon strands are aligned in both longitudinal and transverse directions. Non-corrosive; can be used with as little as 1⁄4” (6 mm) of cover Requires less concrete cover leading to lighter structures Marine structures Thin topping slabs and overlays Lightweight, easy to handle and use; can be cut to fit using conventional tin snips Silos and concrete storage tanks High tensile strength and modulus Outstanding mechanical bond with concrete; requires a mimimum 1⁄4” (6 mm) to develop its strength Precast concrete, including architectural and wall panels Concrete repair and shotcrete PHYSICAL PROPERTIES carbon fiber with glass fiber support and epoxy resin Grid geometry (longitudinal x transverse spacing) Supply form (custom widths and lengths also available) TYPICAL MECHANICAL PROPERTIES TRANSVERSE PROPERTIES 0.002860 in2 Average number of strands per unit width Area of strands per unit width Grid tensile strength per unit width Tensile modulus of elasticity Individual strand cross-sectional area Strand tensile strength Application Use Note: C-GRID® remains a relatively novel material without the extensive performance history of traditional construction materials. Reported properties are average values, not design values. Structures and applications using C-GRID® should be designed using appropriate safety factors or load and strength reduction factors. All applications utilizing C-GRID®, including critical life safety and fire rated structures, should be designed and reviewed by a licensed engineer experienced with FRP materials. The data expressed herein is believed to be accurate at the time of publication; however, it is subject to change without notice. 1. 2. 3. 4. Notes: Centerline-to-centerline spacing between strands is nominal and based on the average number of strands per unit width. Actual spacing may vary by ± 0.10” (± 2.5mm). The longitudinal direction is in the direction of the roll, and the transverse direction is across the width of the roll. For example, if a roll of C-GRID® is 47.5” wide, the carbon strands in the transverse direction are 47.5” in length. If a roll of C-GRID® is 500 yards long, the longitudinal strands are 500 yards in length. Individual strand cross-sectional area is normalized to the cross-sectional area of the fibers in accordance with ACI 440.2R. The actual measured thickness and width are larger and shall not be used for design purposes. Reported tensile strengths are typical or average properties based on testing. Tensile modulus values are based on properties reported by the carbon fiber supplier. C-GRID® exhibits linear elastic behavior, so failure strains are estimated using Hooke’s Law.
