Glass-reinforced plastic

Definition

Glass-reinforced plastic (GRP) is a composite material made from a polymer matrix reinforced with glass fibers, providing strength and durability while remaining lightweight. This material became increasingly important in the development of ocean energy technologies due to its corrosion resistance and structural integrity, which are essential for devices exposed to harsh marine environments.
