BASALT FIBER

Basalt fiber Surface mat combines the properties of glass fiber and carbon fiber surface mats．1t not only helps to form a resin-rich (80％)layer in the surface of a composite Product to make the Surface bright and smooth，but also improves the leakproofness and corrosion resistance of the product．The binder of basalt fiber surface mat is well compatible with the resin matrix．and can improve the moldability of i rregular composite products．The mat iS also a best option for pultrusion and filament-winding Processes．
