Glass fiber Reinforced Plastics (GRP) or Fiber Glass Reinforced Plastics (FRP) is essentially structural materials that belong to the larger family of composite materials. As a matter of fact, modern composites owe their genesis to glass-fiber reinforced polyester developed in the 1940s. The composite basically consists of e-glass fibers and polyester resin that has excellent mould ability with several desired qualities such as lightweight, high strength, high stiffness, toughness, chemical resistance, electrical properties, aesthetic appeal, etc.
Advantages
• Easy mould ability to architectural forms and shapes
• High strength to weight ratio
• Wide performance range
• Low manufacturing cost
• High resistance to impact
• Resistance to corrosion
• Good electrical characteristics
• Heat and sound insulation
• Translucency and color impregnation
Properties
• Properties of typical 4 mm thick hand lay-up GRP laminate are:
• Glass Content: 450 gms/sq m / mm
• Impact Strength: +40 to 45 KJ/ sq m
• Tensile Strength: +75 to 80 N/mm
• Density: 1.6 to 1.8 gms/cubic cm
• Bar of hardness: 45-50
• Pigmented gel coats: Ultra violet stabilized color fast, no fading
• Fire properties (Surface spread of flame):
Class 3 with general purpose resin as per BS476 Part 7, with special resins Class 1 can be achieved
Applications
• Achitectural panels such as decorative column cladding, façade treatment, insulated, none insulated domes of mosques and commercial buildings.
• Bath tubs, shower trays, wash basins, garden fountains
• Manhole liners, septic tanks, holding tankso Portacabins, prefabricated houses, watchman booth, vending kiosks, etc.
• Water tanks, A.C. covers, vanity tops
• Gold and silver jewels finals for mosques and domes
• Artificial rocks, garden planters
• Stadium canopies, electrical enclosures
