Raw materials and applications: Glass fiber has higher temperature resistance, non flammability, corrosion resistance, good insulation and sound insulation, high tensile strength, and good electrical insulation than organic fiber. But it is brittle and has poor wear resistance. Used to manufacture reinforced plastics or reinforced rubber, as a reinforcing material, glass fiber has the following characteristics, which make the use of glass fiber much more extensive than other types of fibers, and its development speed is also listed as follows:

(1) High tensile strength and low elongation (3%).

(2) High elasticity coefficient and good rigidity.

(3) Within the elastic limit, the elongation is large and the tensile strength is high, so the absorption of impact energy is large.

(4) It is an inorganic fiber with non combustible properties and excellent chemical resistance.

(5) Low water absorption.

(6) Excellent scale stability and heat resistance.

(7) Good processability, can be made into products of different forms such as strands, bundles, felt, and woven fabrics.

(8) Transparency can penetrate light.

(9) Good adhesion with resin.

(10) The price is cheap.

(11) Not easy to burn, can melt into glass like beads at high temperatures.
