high strength fiberglass

S2&S4 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,they exhibit 30-40% higher tensile strength,16-20% higher modulus of elasticity,10 folds higher fatigue resistance,100value="150" tcsc="0" unitname="℃" w:st="on">-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
