Glass Reinforced Plastic, a composite material made of plastic reinforced with glass fibers.
Acronym formed in the mid-20th century from 'Glass Reinforced Plastic,' as materials science developed new composite technologies. Also known as fiberglass or GFRP (Glass Fiber Reinforced Plastic), reflecting the manufacturing innovation of combining materials for enhanced properties.
GRP revolutionized industries from automotive to marine engineering because it combines the lightweight properties of plastic with the strength of glass, creating materials stronger than steel yet light enough to float. The random orientation of glass fibers in the plastic matrix distributes stress in all directions, making GRP incredibly resistant to cracking and impact damage.
