FRPs using glass fibers are the predominant reinforcing fiber in all FRPs. E-glass is the most commonly used fiber. It has high electrical insulating properties, good heat resistance, and has the lowest cost. S-Glass fibers have higher heat resistance and about one-third higher tensile strength than E-glass. The specialty AR-glass fibers are resistant to the alkaline environment found in concrete but have much higher cost.
- Well-distributed, uniform tensile strength, good vertical performance.
- Fast impregnation, good mold drapability, easily removing air bladder.
- High mechanical strength, less strength loss in wet condition.
It has high mechanical property, anti-corrosion. Widely applied on yacht, auto, sports equipment, cooling tower.
