Glassfibre Reinforced Plastics (GRP) or Fibre Glass Reinforced Plastics (FRP) are essentially structural materials that belong to the larger family of composite materials.As a matter of fact, modern composites owe their genesis to glass-fibre reinforced polyester developed in the 1940's. The composites basically consists of e-glass fibres and polyester resin, has excellent mouldability combined with several desired qualities like light-weight, high strength, high stiffness, toughness, chemical resistance, electrical properties, aesthetic appeal etc.
