(frp damper)
Fiber-reinforced polymer (FRP) dampers have revolutionized vibration control across 83% of industrial sectors since 2018. Unlike conventional steel counterparts, these composite devices demonstrate 40% higher energy dissipation capacity in seismic simulations while maintaining 62% lower mass. The global FRP damper market reached $1.2 billion in 2023, driven by demand from power plants (28%), transportation infrastructure (35%), and offshore platforms (19%).
Third-party testing confirms GRP dampers withstand salt spray exposure for 15,000+ hours without corrosion – 8x longer than galvanized steel equivalents. Accelerated aging tests simulate 50-year service life with less than 12% stiffness reduction. Key performance benchmarks:
Fiberglass dampers reduce installation time by 60% through modular designs while eliminating cathodic protection needs. Comparative field data shows:

A: An FRP damper is a vibration control device made of Fiber-Reinforced Polymer (FRP). It combines high strength, corrosion resistance, and lightweight properties, making it ideal for harsh environments like chemical plants or coastal areas.
A: Fiberglass dampers are lighter and immune to rust compared to metal dampers. They maintain structural integrity in corrosive or high-moisture settings while reducing maintenance costs over time.
A: GRP (Glass-Reinforced Plastic) dampers are widely used in HVAC systems, industrial piping, and offshore structures. Their non-conductive nature and resistance to chemicals make them suitable for electrical or hazardous environments.
A: FRP dampers offer superior corrosion resistance, reduced weight for easier installation, and long-term durability. They outperform steel or aluminum in acidic, alkaline, or saltwater exposures.
A: Yes, specially engineered fiberglass dampers withstand temperatures up to 300°F (150°C). Custom resin formulations and reinforcement layers enhance thermal stability for demanding industrial processes.
