Carbon-fiber reinforced polymer (CFRP) is currently the leading high-performance fiber used in structural FRP. Its standout advantage is very high specific strength — what is often called "lightweight high-strength."
FRP also offers excellent corrosion resistance, withstanding chemical attack across diverse environments. In chemical-plant buildings, underground works and underwater specialty projects, FRP's corrosion resistance has been validated in actual engineering.
In cold regions and coastal areas of various countries, replacing conventional materials with FRP in bridges and buildings resists de-icing salt and airborne salt corrosion — meaningfully extending service life.
FRP is corrosion-resistant, electrically insulating and non-magnetic, with low thermal conductivity. In addition to its bulk mechanical properties, these traits define its engineering value.
