การแนะนำประสิทธิภาพของผลิตภัณฑ์
Fiber Reinforced Polymer (FRP) rebar is a high-performance alternative to traditional steel reinforcement bars used in concrete structures. Made from a combination of fibers such as glass, carbon, or basalt and a polymer resin matrix (usually vinyl ester, polyester, or epoxy), FRP rebar provides superior resistance to corrosion, making it ideal for use in environments where traditional steel reinforcement would deteriorate over time due to exposure to moisture, salt, or chemicals.
One of the most significant advantages of FRP rebar is its non-corrosive nature. In structures such as bridges, marine environments, tunnels, and parking garages, corrosion of steel rebar can lead to spalling, cracking, and overall structural degradation. FRP rebar eliminates this problem, offering a much longer service life and reducing maintenance costs. It is also lightweight—approximately 20% of the weight of steel—which makes transportation, handling, and installation easier and more cost-effective.
FRP rebar also boasts high tensile strength. Although it is not as ductile as steel, FRP can achieve similar structural performance when properly designed. Its electromagnetic neutrality makes it suitable for use in sensitive applications such as MRI rooms or near power transmission lines, where metallic interference would be problematic. Additionally, it does not conduct electricity, enhancing safety in specific installations.
The manufacturing of FRP rebar involves specialized machines designed to combine the fibers and resin into a strong composite bar. FRP rebar production machines are typically automated and involve a pultrusion process. In this process, continuous strands of fiber are pulled through a resin bath, where they are coated and saturated. The saturated fibers are then pulled through a heated die that shapes and cures them into the desired diameter and surface texture of the rebar.
Modern FRP rebar machines are engineered for high efficiency, consistent quality, and scalable output. They can produce rebar in various diameters, surface deformations (for improved bonding with concrete), and lengths. The control systems on these machines allow precise monitoring of speed, temperature, and material ratios to ensure uniform quality. Some advanced systems even integrate quality control mechanisms such as infrared scanners and automatic cutting units for continuous operation.
In recent years, the adoption of FRP rebar and its manufacturing technology has grown significantly due to increasing awareness of sustainable building materials and the rising costs associated with steel corrosion. Governments and infrastructure agencies around the world are incorporating FRP rebar into standards and design codes, paving the way for broader use in civil engineering projects.
The market for FRP rebar and related machinery is expected to grow substantially over the next decade. As the construction industry seeks to meet sustainability goals and reduce lifecycle costs, the demand for durable, non-corrosive reinforcement will continue to rise. Manufacturers of FRP rebar machines are responding with more advanced, automated systems to meet this demand efficiently.

คำถามที่พบบ่อย
ถาม :
Is FRP rebar as strong as steel?
ตอบ :
Yes, FRP rebar has higher tensile strength than steel (up to 1,500 MPa), but it has a lower modulus of elasticity, meaning it stretches more under load. It is designed to match or exceed steel's performance in properly engineered structures.
ถาม :
Can FRP rebar be bent on-site?
ตอบ :
No. Unlike steel, FRP rebar cannot be bent after manufacturing. All bends or shapes must be pre-formed in the factory to required specifications.
ถาม :
Is FRP rebar approved in building codes?
ตอบ :
Yes. Many countries now include FRP rebar in their design standards and building codes, such as ACI 440.1R in the U.S. and CSA S806 in Canada. Approval depends on local regulations and project specifications.
ถาม :
Does FRP rebar bond well with concrete?
ตอบ :
Yes. FRP rebar is manufactured with surface treatments (e.g., sand-coating, helical wraps) to enhance bonding with concrete, achieving bond strengths similar to or better than steel.
ถาม :
What is the lifespan of FRP rebar?
ตอบ :
FRP rebar can last over 100 years in harsh environments due to its corrosion-resistant properties, significantly outperforming steel in high-moisture or chemically aggressive settings.
ถาม :
Is FRP rebar more expensive than steel?
ตอบ :
Initial cost of FRP rebar is typically higher, but the lifecycle cost is lower due to reduced maintenance, longer lifespan, and corrosion resistance.
ถาม :
Can FRP rebar be recycled?
ตอบ :
FRP rebar is not recyclable in the same way as steel, but it can be reused in some cases and disposed of as non-hazardous waste. Some research is being done into composite recycling techniques.
