Steel and concrete may be very hard materials, but they are not impenetrable by corrosion. Complete replacement or construction of new structures is expensive, and we know you don’t always have time to do so. Composite strengthening reinforcement systems can be used to increase strength, reinforcement and load-bearing capacity, which is an effective and affordable option.
Fiber-reinforced polymer (FRP) composite material system to enhance bending, shear, axial load, and seismic upgrades of various structures. Carbon fiber reinforced plastics (CFRP) are used in these applications, and carbon fiber reinforced plastics are used in most structural applications. FRP composite materials have been used for decades in the aerospace and manufacturing fields, which require low weight, high tensile strength and non-corrosive structural properties. In civil engineering applications, carbon fiber has proven to be a very effective external bonding reinforcement. Carbon fiber composites are successful because they have low creep properties, and compared to steel, they are thinner and lighter, and their tensile strength is 10 times that of steel. In addition to bonding carbon fiber cloth to the concrete surface, it can also be placed in a slot in the concrete to strengthen the structure's bending and shear reinforcement applications.
Types of composite strengthening reinforcement systems:
Structural carbon fiber fabric system
Structural carbon plate system
Aadhesive
Advantages of composite strengthening reinforcement
Less likely to interfere with other finishes or building components
The carbon fiber reinforcement system is very light. When a structure already needs additional reinforcement, the last thing you should do is increase its own weight
Composite materials can be adapted to existing surfaces. Use in small spaces, unique angles and different positions to provide greater flexibility and eliminate unnecessary changes to the structure
Carbon fiber reinforced plastics and carbon fiber reinforced plastic product systems can provide many cost-effective advantages, requiring less infrastructure changes and simplified installation procedures
Lightweight and economical solutions to improve the bending, axial and shear strength of existing concrete structures and components
Application of composite strengthening reinforcement
The FRP composite strengthening industry initially started with the seismic retrofitting of bridge columns, but since then it has gained momentum in various applications.
