S2&S4 highstrength fiberglass made from the magnesium alumina silicateglass system meeting the needs of military application have beendeveloped and put into volume production since 70's & 90's last centuryrespectively.

Compared with Eglass fiber,they exhibit 30-40% higher tensile strength,16-20% higher modulusof elasticity,10 folds higher fatigue resistance,100-150℃ highertemperature endure,also they have excellent impact resistance because of highelongation to break,highageing & corrosion resistance,quick resin wet-out properties.
