S glass

S glass is a high strength fiberglass  made from the magnesium alumina silicate glass system meeting the needs of military application have been developed and put into volume production since 70's & 90's last century respectively.

Compared with E glass fiber,S glass 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.
