What Does Fiberglass Reinforced Plastic (FRP) Mean?
Fiberglass reinforced plastic (FRP) is a chemically reinforced type of material that is composed of a thermoset resin matrix and engineered fibers to improve durability.
FRPs are widely used for several industrial applications due to their improved physical characteristics. They have greater chemical and corrosion resistance compared to steel and other metals. They also have a low maintenance rate and a longer product lifetime.
Corrosionpedia Explains Fiberglass Reinforced Plastic (FRP)
Fiberglass reinforced plastic (FRPs) are made up of thermoset polymer resins and fibers. Examples of such resins are vinyl ester, epoxy and phenol formaldehyde. Examples of such fibers are basalt, carbon and glass.
There are five major types of fiberglass used for FRP production:
- A-glass (alkali glass) - Good chemical resistance, poor electrical properties
- C-glass (chemical glass) - High chemical resistance
- E-glass (electrical glass) - Good insulation and water resistance
- S-Glass (structural glass) - Good mechanical properties
- D-glass (dielectric glass) - Best electrical properties, poor mechanical properties
