Carbon Fiber Reinforced Grids (CFRG) are a type of high-performance composite grid formed using patented technology. Continuous bidirectional carbon fibers are fully impregnated with resin and cured, resulting in this rigid grid structure. CFRG boasts significant advantages such as being lightweight, high-strength, and possessing excellent corrosion resistance, demonstrating unique application value in the field of civil engineering.
The joints of CFRG are meticulously crafted using a special bidirectional interlocking process. Compared to similar FRP (Fiber Reinforced Polymer) bars, this process significantly reduces the required lap splice and anchorage lengths. This not only saves material but also simplifies construction procedures. When used in conjunction with specifically developed anchorage systems, CFRG achieves excellent composite action with cementitious materials. This synergy fully unlocks the ultra-high performance of the carbon fibers, substantially enhancing the load-bearing capacity of structures. Traditional flexible grids cannot achieve this effect.
As a novel structural material in civil engineering, CFRG is not only suitable for strengthening and retrofitting existing concrete and masonry structures, significantly improving the safety and durability of existing buildings, but can also serve as reinforcement material in new concrete structures. It provides reliable assurance for the high-quality construction of modern buildings and is one of the important materials driving technological innovation and development in civil engineering.
