Question

The most commonly used material for glass fiber is
O
B203
O P205
O Ge02
o SiO2​

Answer 1

SiO2

Explanation:

E-glass fibers are the most widely used among all fibrous reinforcements, because of their low cost and relatively low elastic moduli compared to other reinforcements. S-glass fibers are stiffer and stronger than E-glass ones, and have better resistance to fatigue and creep.

Answer 2

Aluminum boron silicate
Aluminum boron silicate glass fibers containing alkali oxide components such as aluminum oxide, less than 1% or less than 0.8%. So it contains very little alkali. It is the most widely used glass fiber formula in the world.
