FRP Materials: Engineering Excellence in Extreme Conditions

Fiber-reinforced polymer (FRP) and glass-reinforced plastic (GRP) materials have become indispensable in thermal and nuclear power applications. These composites withstand temperatures up to 300°C while maintaining structural integrity, outperforming traditional steel alloys by 40% in corrosion resistance. The global market for FRP in energy sectors is projected to reach $2.8 billion by 2028, driven by increasing demand for radiation-resistant materials.

Technical Superiority Over Conventional Materials

FRP products demonstrate exceptional thermal stability, with coefficient of thermal expansion values 80% lower than metallic alternatives. Key technical merits include:

Radiation attenuation capacity: 92% neutron absorption at 15mm thickness
Continuous service temperature: -60°C to 320°C
Hydrochloric acid resistance: 0.02mm/year erosion rate

Independent testing confirms FRP maintains 98% tensile strength after 10,000 hours at 250°C, surpassing ASME BPVC-IV requirements.
