The versatility of glass as a fiber makes it a unique industrial textile material. Fiber glass in fabric form offers an excellent combination of properties from high strength to fire resistance. Wide ranges of yarn sizes and braided patterns provide huge number of design potential allowing the end user to choose the best combination for material performance, economics and product flexibility. The combination of properties such as low moisture absorption, high strength, heat resistance and low dielectric constant makes fiber glass fabrics ideal as a reinforcement for printed circuit boards and insulating varnishes.

General Characteristics:

-high surface weight ratio
-amorphous structures
-possible 
 same properties in fiber longitudinal and transverse directions
-In contrast to carbon fiber, glass can undergo more elongation before it breaks
-semi-rigid material
-no stretch or shrink after exposure extremely high or low temperatures 
 returns toloads near the breaking point -----
almost back to its original shape.
