Corrosion Resistance of Various Glass Fiber Reinforcements

For non-load bearing applications using composite materials the polymer matrix typically governs the corrosion performance of the composite. However, in load bearing applications using glass fiber reinforced composite materials the choice of glass fibers is crucial for the long term structural performance of the composite. A number of choices of different glass fibers types are available and not all are suited for corrosive environments. All of these types and their specialty applications will be discussed with attention focused mainly on the most widely used standard E-glass and boron-free E-glass.
