What are difference between FRP and GRP?
A: FRP stands for fiber-reinforced plastics, it’s a term typically used stateside here in North America. GRP is a term that means the same thing. But it’s generally used over in Europe and Asia and stands for glass-reinforced plastic.
The backbone of the industrial revolution has always been thought to be led by the steel industry. While steel still plays an especially important role in structural building it has drawbacks. In fact, all metals do because even the strongest metal will eventually succumb to rust. Whether aluminum or steel—there is no metal impervious to the elements.
Wood is even more fragile as even though it does not rust, it can be weakened by moisture. It can also be broken by force, ravaged by termites, or succumb to mold.
Some might suggest simple plastic as an alternative and while they’re on the right path—it’s not quite right. Plastic alone can warp and will crack or melt when exposed to high temperatures, and it lacks strength. However, the solution isn’t too far from it.
FRP IS THE ANSWER
In all honesty, there is not a substance on earth that can hold its shape, strength, and structural integrity forever—but FRP comes awfully close.
Now, here in North America, we refer to this superior substance as FRP which as mentioned stands for fiber-reinforced plastic. It is a term that encompasses a wide array of products and applications. In Europe and Asia, they have the same product, but it’s called GRP—glass reinforced plastics. It is the same exact thing, simply different terminology like how a trunk here is a boot in England.
FRP is a composite material comprised of a matrix of a thermoset resin, and is reinforced using fibers. There are many different types of resins used in making FRP depending on the application
