FRP Bridge Vacuum Infusion Method

FRP Bridge Vacuum Infusion Method

A bridge that is resistant to salt damage, lightweight, high-strength, and does not decay.

Vacuum Infusion The entire glass fiber mat layered on the mold is covered with a film and sealed, creating a complete vacuum state by removing the air from the glass fiber layer. Next, using the power of the vacuum, polyester resin is injected into the glass fiber layer, ensuring it spreads evenly to create a uniform and strong FRP laminate. This manufacturing method is referred to as "Vacuum Infusion (VI)." This technique is also used in the production of large blades for wind turbines and yacht hulls. Laminates produced using this method are used in the structural components of FRP bridges. The high glass fiber content allows for lightweight and strong laminates, and there is the advantage of being able to produce very large laminate sheets. The shape of the mold can be freely designed, whether flat or curved, enabling the creation of elegantly shaped bridge girders.

Underground buried tank leak detection device with inner FRP double-shell structure.

Eliminate abnormal pressure fluctuations in the small space between the outer shell of the SF double-shell tank made of FRP and the inner shell made of steel at low cost! No need for repairs at each location every time an anomaly is detected!

Underground tanks at facilities handling hazardous materials such as SS have been equipped with SF double-walled tanks since around 1994, and as of March 31, 2011, a total of 41,572 SF double-walled tanks have been installed. In this situation, during leakage inspections of underground tanks, abnormal pressure fluctuations have been confirmed in the small space between the outer FRP shell and the inner steel shell of the SF double-walled tanks. Even if the cause is identified and the leakage point is repaired, there are cases where new abnormalities appear elsewhere, or abnormalities in different locations are confirmed several years after the first repair, making it impossible to guarantee that past repair work will be completed in one go. However, the fire department is also struggling with the reality that they cannot provide strong guidance due to economic issues. Our company's "Underground Storage Tank Leakage Detection Device with Inner FRP Double-Wall Structure" offers a low-cost solution to these problems. 【Benefits】 - There is no need to repair each location every time an abnormality is detected. - The number of facilities that cannot be repaired due to economic reasons decreases, reducing the risk of accidents. - Even facilities that cannot be inspected frequently can be safely monitored from a remote location. *For more details, please download the PDF or contact us.

Gain CF sheet method [Structural reinforcement and peeling prevention measures]

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.
