Compared with E glass fiber,S glass fiber exhibit 30-40% higher tensile strength,16-20% higher modulus of elasticity,10 folds higher fatigue resistance,100-150℃ higher temperature endure,also they have excellent impact resistance because of high elongation to break,high ageing & corrosion resistance,quick resin wet-out properties.
