Raw material and its application: Glass fiber has higher temperature resistance than organic fiber, non-combustible, anti-corrosion, good heat and sound insulation, high tensile strength, and good electrical insulation. But it is brittle and has poor wear resistance. It is used to make reinforced plastics (see color picture) or reinforced rubber. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fiber far more extensive than other types of fibers, and its development speed is also far ahead. Its characteristics are listed as follows:
(1) High tensile strength and low elongation (3%).
Glass fiber cut yarn
(2) High elastic coefficient and good rigidity.
(3) The elongation is large within the elastic limit and the tensile strength is high, so the impact energy is large.
(4) It is an inorganic fiber with non-combustibility and good chemical resistance.
(5) Low water absorption.
(6) Dimensional stability and heat resistance are good.
