FRP Bridge Vacuum Infusion Method
A bridge that is resistant to salt damage, lightweight, high-strength, and does not decay.
Vacuum Infusion The entire fiberglass mat layered on the mold is covered with a film to seal it, and the air from the fiberglass layer is removed to create a complete vacuum state. Next, using the power of the vacuum, polyester resin is injected into the fiberglass layer, ensuring it spreads evenly throughout, resulting in 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 the hulls of yachts. Laminates produced using this method are used in the structural components of FRP bridges. The high fiberglass 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 as either flat or curved, enabling the creation of elegantly shaped bridge beams.
