Raw material and its application: glass fiber has higher temperature resistance than organic fiber, non-combustible, anti-corrosion, good heat insulation and sound insulation, high tensile strength, and good electrical insulation. But it is brittle and has poor wear resistance. Industrial filter materials, anti-corrosion, moisture-proof, heat insulation, sound insulation, shock-absorbing materials. It can also be used as a reinforcing material to make reinforced plastic 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 the development speed is far ahead.
The characteristics are listed as follows
(1) High tensile strength and small elongation (3%).
(2) High elastic coefficient and good rigidity.
(3) The elongation within the elastic limit is large and the tensile strength is high, so the impact energy can be absorbed greatly.
(4) It is an inorganic fiber, which is non-combustible and has good chemical resistance.
(5) Small water absorption.
(6) Dimensional stability and heat resistance are good.
(7) Good processability, can be made into strands, bundles, felts, weaving and other products in different forms.
(8) Transparent and can pass through light.
(9) The development of a surface treatment agent with good adhesion to resin has been completed.
(10) CHEAP.
(11) It is not easy to burn, and can be melted into glassy beads at high temperature.
