Types of Glass Fibre

E-glass (electrical): lower alkali content (<1%) and stronger.
Good tensile and compressive strength and stiffness, good electrica properties and relatively low cost, but impact resistance relatively poor.
E-glass is the most common form of fibre used in polymer composites.

C-glass (chemical): best resistance to chemical attack.
Mainly used in the form of surface tissue in the outer layer of
laminates used in chemical and water pipes and tanks.

R, S or T-glass: manufacturers trade names of equivalent fibres. R (Vetrotex,
France), S (Owen Corning, USA) and T (Nittobo, Japan)
Having higher tensile strength and modulus than E glass, with
better wet strength retention. Higher ILSS and wet out properties
are achieve through smaller filament diameter.

A-glass: Soda lime glass with high alkali content between 10-15%.
Very poor mechanical properties but high resistant to chemical attacks.

D-glass: Improved dielectric glass developed for high performance electronic applications.
