GRP vs. FRP: What's the Difference?

Nov / 09 / 2023
grp vs frp

GRP and FRP are both composite materials that are made up of a matrix and a reinforcement. The matrix is a polymer that holds the reinforcement together,and the reinforcement provides strength and stiffness.

What is GRP?

GRP (Glass-Reinforced Plastic): This term specifically refers to FRP where the reinforcing fibers are made of glass. GRP is more widely used in Europe and Asia.

What is FRP?

FRP (Fiber-Reinforced Plastic): This is the broader term, encompassing any composite material where plastic is strengthened with fibers. These fibers can be made of glass, carbon, aramid (like Kevlar), basalt, or other materials. FRP is more commonly used in North America.

What are the similarities between GRP and FRP?

GRP and FRP are both composite materials that are made up of a matrix and a reinforcement. They are both strong, lightweight, and corrosion-resistant.

What are the differences between GRP and FRP?

In essence, GRP is a type of FRP, but not all FRP is GRP. When choosing between them, it depends on the specific properties you need. Here are some generalities:

Strength and Elasticity: FRP using fibers like carbon can be stronger and stiffer than GRP.

Heat Resistance: Some FRP types can have better heat resistance than GRP.

Applications: FRP is used in a wider range of industries like automotive, aerospace, and construction. GRP is more common in the power industry.

Which material is right for you?

If you're unsure which term to use, FRP is generally a safe bet as it's the broader term. But if you know for sure the reinforcement is fiberglass, then GRP is the more specific term.
