Gain CF sheet method [Structural reinforcement and peeling prevention measures]
High-strength carbon fiber "Gaina CF Sheet" demonstrates significant reinforcement and repair effects on concrete structures without applying any load.
The Gain CF Sheet Method is a technique that involves applying carbon fiber sheets treated with high adhesive penetration to concrete structures for the repair and reinforcement of tunnels. It has passed tests for "flammability, self-extinguishing properties, and the safety of emitted gases," making it suitable for use within tunnels. Additionally, the sheets are treated for high penetration and, when combined with a specialized adhesive, exhibit excellent adhesive performance. This helps to prevent the sheets from peeling during construction, ensuring safe installation. There are two types of sheets with different weaves: the "CR" type, primarily used for fall prevention, which incorporates carbon fibers woven in both vertical and horizontal directions, and the "UD" type, designed for reinforcement, which aligns carbon fibers in one direction. With the addition of the UD300, which has a weight of 300g/m², alongside the existing UD200 and CR200 (both with a weight of 200g/m²), the application range of the Gain CF Sheet Method has expanded.
basic information
The Gain CF sheet method has the following features: ■ Workability - The materials and equipment used are lightweight, allowing for manual labor without the need for heavy machinery. - The Gain CF sheet can be easily cut and processed, making it simple to install according to the shape of the site. - The equipment used is compact, enabling work in confined spaces. ■ Durability - The materials used are non-corrosive, ensuring stability in tunnel environments. ■ Reinforcement Effect - The Gain CF sheet has a specific gravity that is one-fourth that of iron, yet its tensile strength is 6 to 10 times greater, effectively reinforcing concrete without adding load to concrete structures and preventing the spalling of concrete fragments. ■ Cost - By joining Gain CF sheets, continuity is ensured, allowing for application to various shapes and areas, which standardizes construction and enhances economic efficiency. ■ Quality - The Gain CF sheet CR type uses carbon fibers that have undergone an opening treatment, resulting in high resin impregnation and excellent CFRP performance, leading to stable quality.
