High Strength: Double stronger than steel yet weighs about 60% less.
Chemical Resistance: When treated with appropriate resins, composites with outstanding resistance to chemicals can be developed. The glass fibre resists attack from most chemicals.
Compatibility: Accepts different types of sizes enabling it to be compatible with many synthetic resins as well as mineral matrices like cement, plaster etc.
Part Consolidation: Composite materials of glass fibre can be used to produce one piece part which integrates several functions and thus replacing several other assemblies.
Durability: Does not degrade, or deteriorates as insects or rodents can not attack them.
Fatigue Life: Exhibits very good fatigue properties and can undergo very long cyclic loads without fatigue.
Incombustible: Being a mineral material is neither combustible nor supports combustion. When exposed to heat, it neither emits smoke nor toxic gases.
Inherent resistance to microbiological attack, corrosion and erosion.
Acceptable cost level.
The capability of plastics to be molded into single parts of complete shape and dimensions is a distinct advantage.
