What is the difference between FRP and GRP?
• FRP is a composite material, where high strength fibres are included in a polymer matrix. They are used in many commercial and engineering applications due to their high strength and light weight. FRP is widely used as a substitute for metal and wood. Best example is the use of carbon fibre reinforced polymer (CFRP) instead of aluminum and titanium or high grade steel in aircrafts.
• Fibreglass or GRP is a composite material made out of glass fibres and uses polyester, vinyl, or epoxy as the polymer. It is used to make gliders, boats, and bathtubs. Fibreglass is used mainly for commercial applications. Fibre glass is one type of FRP.
