Carbon Fiber Reinforcement Polymer (CFRP) Systems
Carbon Fiber Reinforcement Polymer (CFRP) System
INFRASTRUCTURE REPAIR
RepWrap 300 UD and RepWrap 600 UD are lightweight, high-tensile strength, stitch bonded, uni-directional carbon fabric that is produced from our continuous, low-carbon fiber. It easily wets out with RepWrap Bond saturating resin and can be installed using either the “wet lay-up” or “dry lay-up” technique. The light weight of the fabric allows dry application to RepWrap Bond epoxy coated surfaces followed with a saturating coat of RepWrap Bond Saturant, and finally by RepCoat UV anti-carbonization and UV resistant topcoat significantly simplifying field application.
TuffTex Materials RepWrap Systems are used to obtain a bonded CFRP (Carbon fiber reinforced polymer) field laminate reinforcement system that will strengthen and enhance the performance of structural elements once installed.
1 | Concrete
It is preferred to have an ICRI profile of CSP 3. Surface can be profiled and prepared for CFRP application with PrepEtch biodegradable etching compound.
​
2 | RepPatch VOH Concrete Patching Compound or RepCrete QP polymer concrete may be used if needed.
​
3 | RepWrap Bond saturant Wet and dry layup SAT should be applied at 40-50 sf per gallon.
​
4 | RepWrap Sheets: 300UD or 600UD
Shall be cut beforehand into prescribed lengths. Sheets shall be lapped in longitudinal direction 6 inches minimum or as needed. (Note: no lapping is required of the sheets parallel to the direction of fiber orientation). Apply FRP/CFRP sheets fiber side down to the concrete over fresh saturant using a ribbed roller and squeegee to remove any air bubbles.
​
5 | RepWrap Bond
2nd coat should be applied at 100 sf per gallon.
​
6 | RepCoat UV
Topcoat should be applied at 130-150 sf per gallon.

RepWrap™ Bond Hi-Mod, Moisture Tolerant CFPR Saturating Resin RepWrap™ Bond is a two-component, high modulus, low viscosity, high strength, 100% solids, structural-epoxy adhesive for use with TuffTex Materials’s FRP Structural Strengthening Systems. RepWrap™ Bond provides a long working time for application with no offensive odor.
RepPatch™ VOH - Vertical/Overhead Mortar One Component Polymer-Modified Vertical & Overhead Repair Mortar RepPatch™ VOH is a single component, polymer-modified, cement-based mortar designed to repair and rehabilitate vertical and overhead concrete and masonry surfaces without the need for costly form work.
RepCrete™ QP - Quick Patch Concrete Repair - TXDOT Approved! Horizontal Road & Deck Patching Mortar Kit. RepCrete™ QP is a unique three-component rapid curing, non-shrink, hybridized polymer based elastomeric concrete that cures to a dense, semi-flexible, weather, abrasion and impact resistant polymer mortar for the repair of spalls on roadways, bridges and parking decks.
RepCoat™ UV CFRP Topcoat & Protective Coating TuffCoat UV forms a weatherproof barrier against nature’s harsh extremes. Steel and concrete structures expand and contract in response to the weather and structural stresses. Unlike typical exterior coating, this coating fills and bridges hairline cracks, helping to prevent damaging water penetration. It passes Federal Specification TT-C-555B, sec.3.3.3, withstanding 98 mph wind-driven rain.
